The husks of mature Caracas cacao fruits extracted with EtOH and Me₂CO, the residue heated 0.5 h. at 15 lb. pressure in an autoclave with H₂O (50 cc./g.) and filtered, the filtrate poured into 2 volumes 95% EtOH, and the precipitated H₂O-soluble polysaccharide (I) washed with EtOH and dried over CaCl₂ in a vacuum desiccator gave material, [α]_D²⁵ 114°, intrinsic viscosity 10.12, pH 1% solution 6.36, natural ash 8.2%, ash after dialysis 0.3%, containing 0.557% N. The seed shaken 2 h. at room temperature with H₂O, and the mucilaginous seed coat extracted in a similar manner gave the seed polysaccharide (II), [α]_D²⁵ 106°, intrinsic viscosity 6.73, pH 1% solution 6.85, ash natural 8.3%, ash after dialysis 0.2%, containing 3.68% N. Aqueous 1% I diluted at 25° with stirring with increments of absolute EtOH, the mixture stirred after addition of each increment 10 min. and centrifuged 10 min. at 804 times gravity, and the precipitates dried and weighed gave only in the range 54.5-62.0% by volume EtOH precipitates II precipitated under similar conditions within the range 64.8-70.0% EtOH. Aqueous 1% I precipitated in the same manner with 1.0M KCl gave a precipitate of 16.5% of the I by a total KCl molarity of 0.60; no precipitation of II occurred up to 0.83M KCl concentration Sep. samples of I hydrolyzed 8 h. at 100° with N H₂SO₄ or HCl, neutralized with BaCO₃ or Ag₂O, resp., and the hydrolyzate chromatographed on paper showed the presence of rhamnose (III), arabinose (IV), glucose (V), galactose (VI), and a slow moving spot. I (and II) gave a pos. test for P and neg. tests for urinic acid and sulfate. I hydrolyzed at 43° with 2% H₂SO₄, and 2-cc. aliquots withdrawn periodically, neutralized with BaCO₃, filtered, and chromatographed showed the following order of release of monosaccharides: IV 0.5 h., VI 1.5 h., mannose and phosphate 8 h., III 12 h. II gave similarly: IV 0.5 h., mannose 1.5 h., VI 5, III and phosphate 8 h. I hydrolyzed with 5% H₂SO₄ and in another case with 43% HCl, the resulting sugar sirup (3.8 g.) chromatographed with 18:3:1:4 EtOAc-AcOH-HCO₂H-H₂O on a cellulose column gave 246 mg.

VI plus a trace V [α-D-VI, m. 160-1° (from aqueous AcOH), [α]_D²⁵ 81.2° (equilibrium)]. The unknown pentose saccharide crystallized from MeOH melted at about 35°, resolidified at 60-70°, and melted again at about 190°. Aqueous 2% I and II hydrolyzed 8 h. at 100° by N H₂SO₄, neutralized with BaCO₃, and the hydrolyzate chromatographed on Whatman Number 1 paper for 40 h. with EtOAc-pyridine-H₂O (8:2:1) showed the following compositions (% given): I: 37.97 III, 13.27 IV, VII plus trace of V 9.98, VI 38.77. II: 36.29 III, 28.81 IV, VII plus trace of V 12.02, VI 22.86. H₂O-soluble polysaccharides were isolated from the pulp, the mucus seed cover, and the seed placenta in yields of 0.17, 0.10, and 0.01% of the dry fruit; hydrolysis of these polysaccharides gave the same monosaccharides as I and II; the placenta and mucus also contained traces of xylose in contrast to II.

(2R,3R,4S,5S)-2,3,4,5-tetrahydroxyhexanal hydrate (cas: 10030-85-0) belongs to alcohols. Because alcohols are easily synthesized and easily transformed into other compounds, they serve as important intermediates in organic synthesis. Converting an alcohol to an alkene requires removal of the hydroxyl group and a hydrogen atom on the neighbouring carbon atom. Dehydrations are most commonly carried out by warming the alcohol in the presence of a strong dehydrating acid, such as concentrated sulfuric acid.Safety of (2R,3R,4S,5S)-2,3,4,5-tetrahydroxyhexanal hydrate

Origanum vulgare L. essential oil inhibits virulence patterns of Candida spp. and potentiates the effects of fluconazole and nystatin in vitro was written by Cid-Chevecich, Camila;Muller-Sepulveda, Andrea;Jara, Jose Antonio;Lopez-Munoz, Rodrigo;Santander, Rocio;Budini, Mauricio;Escobar, Alejandro;Quijada, Raul;Criollo, Alfredo;Diaz-Dosque, Mario;Molina-Berrios, Alfredo. And the article was included in BMC Complementary Medicine and Therapies in 2022.Recommanded Product: 5-Isopropyl-2-methylphenol This article mentions the following:

Recurrence and resistance of Candida spp. infections is associated with the ability of these microorganisms to present several virulence patterns such as morphogenesis, adhesion, and biofilm formation. In the search for agents with antivirulence activity, essential oils could represent a strategy to act against biofilms and to potentiate antifungal drugs. To evaluate the antivirulence effect of Origanum vulgare L. essential oil (O-EO) against Candida spp. and to potentiate the effect of fluconazole and nystatin. The effect of O-EO was evaluated on ATCC reference strains of C. albicans and non-albicans Candida species. Min. inhibitory concentration (MIC) was determined through broth microdilution assay. Adhesion to microplates was determined by crystal violet (CV) assay. An adapted scratch assay in 24-well was used to determine the effect of essential oil on biofilms proliferation. Viability of biofilms was evaluated by MTT reduction assay and through a checkerboard assay we determined if O-EO could act synergistically with fluconazole and nystatin. MIC for C. albicans ATCC-90029 and ATCC-10231 was 0.01 mg/L and 0.97 mg/L, resp. For non-albicans Candida strains MIC values were 2.6 mg/L for C. dubliniensis ATCC-CD36 and 5.3 mg/L for C. krusei ATCC-6258. By using these concentrations, O-EO inhibited morphogenesis, adhesion, and proliferation at least by 50% for the strains assayed. In formed biofilms O-EO decreased viability in ATCC 90029 and ATCC 10231 strains (IC50 7.4 and 2.8 mg/L resp.). Finally, we show that O-EO interacted synergistically with fluconazole and nystatin. This study demonstrate that O-EO could be considered to improve the antifungal treatment against Candida spp. In the experiment, the researchers used many compounds, for example, 5-Isopropyl-2-methylphenol (cas: 499-75-2Recommanded Product: 5-Isopropyl-2-methylphenol).

5-Isopropyl-2-methylphenol (cas: 499-75-2) belongs to alcohols. Alcohols are among the most common organic compounds. They are used as sweeteners and in making perfumes, are valuable intermediates in the synthesis of other compounds, and are among the most abundantly produced organic chemicals in industry. Alcohols may be oxidized to give ketones, aldehydes, and carboxylic acids. These functional groups are useful for further reactions. Oxidation of organic compounds generally increases the number of bonds from carbon to oxygen (or another electronegative element, such as a halogen), and it may decrease the number of bonds to hydrogen.Recommanded Product: 5-Isopropyl-2-methylphenol

Solvent and additive-free efficient aerobic oxidation of alcohols by perovskite oxide-based heterogeneous catalyst was written by Kumar, Nikhil;Naveen, Kumari;Bhatia, Anita;Muthaiah, Senthilkumar;Siruguri, Vasudeva;Paul, Avijit Kumar. And the article was included in Reaction Chemistry & Engineering in 2020.Formula: C7H6Cl2O This article mentions the following:

A new heterogeneous catalyst for the solvent-free efficient oxidation of alcs. has been developed for a sustainable future with a green reaction technol. This work presents the additive and solvent-free catalytic conversions of primary and secondary alcs. as well as diols into their corresponding carbonyl compounds in moderate to excellent yields. The developed catalyst system is green as it oxidises alcs. under solvent-free conditions and uses simple atm. oxygen as the oxidising agent. We have exptl. proved that the alc. oxidation reaction proceeds through an aerobic oxidative pathway. The double perovskite oxide catalyst CaLaScRuO_6+δ was prepared by the conventional solid-state method. The crystal structure was refined and characterized thoroughly to observe the effect of mixed valent Ru⁵⁺/Ru⁴⁺ ions in the oxygen-rich disordered structure. The conversion of diols into four-, five- and six-membered lactones can enhance the novelty of the present catalyst. The catalyst was found to be very selective for the alc. oxidation and resulted in the oxidised product without affecting the other functional groups present in the aromatic ring. A reaction mechanism has been proposed for understanding the possible role of mixed metals in heterogeneous catalysis. In the experiment, the researchers used many compounds, for example, (2,4-Dichlorophenyl)methanol (cas: 1777-82-8Formula: C7H6Cl2O).

(2,4-Dichlorophenyl)methanol (cas: 1777-82-8) belongs to alcohols. Alcohols are among the most common organic compounds.

Ultrasound-assisted nanoemulsion of Trachyspermum ammi essential oil and its constituent thymol on toxicity and biochemical aspect of Aedes aegypti was written by Subaharan, Kesavan;Senthamarai Selvan, Periyasamy;Subramanya, Thagare Manjunatha;Senthoorraja, Rajendran;Manjunath, Sowmya;Das, Tania;Pragadheesh, Vppalayam Shanmugam;Bakthavatsalam, Nandagopal;Mohan, Muthu Gounder;Senthil-Nathan, Sengottayan;Uragayala, Sreehari;Samuel, Paulraj Philip;Govindarajan, Renu;Eswaramoorthy, Muthuswamy. And the article was included in Environmental Science and Pollution Research in 2022.HPLC of Formula: 499-75-2 This article mentions the following:

Aedes aegypti is the main vector of yellow fever, chikungunya, Zika, and dengue worldwide and is managed by using chem. insecticides. Though effective, their indiscriminate use brings in associated problems on safety to non-target and the environment. This supports the use of plant-based essential oil (EO) formulations as they are safe to use with limited effect on non-target organisms. Quick volatility and degradation of EO are a hurdle in its use; the present study attempts to develop nanoemulsions (NE) of Trachyspermum ammi EO and its constituent thymol using Tween 80 as surfactant by ultrasonication method. The NE of EO had droplet size ranging from 65 ± 0.7 to 83 ± 0.09 nm and a poly dispersity index (PDI) value of 0.18 ± 0.003 to 0.20 ± 0.07 from 1 to 60 days of storage. The NE of thymol showed a droplet size ranging from 167 ± 1 to 230 ± 1 nm and PDI value of 0.30 ± 0.03 to 0.40 ± 0.008 from 1 to 60 days of storage. The droplet shape of both NEs appeared spherical under a transmission electron microscope (TEM). The larvicidal effect of NEs of EO and thymol was better than BEs (Bulk emulsion) of EO and thymol against Ae. aegypti. Among the NEs, thymol (LC50 34.89 ppm) had better larvicidal action than EO (LC50 46.73 ppm). Exposure to NEs of EO and thymol causes the shrinkage of the larval cuticle and inhibited the acetylcholinesterase (AChE) activity in Ae. aegypti. Our findings show the enhanced effect of NEs over BEs which facilitate its use as an alternative control measure for Ae. aegypti. In the experiment, the researchers used many compounds, for example, 5-Isopropyl-2-methylphenol (cas: 499-75-2HPLC of Formula: 499-75-2).

5-Isopropyl-2-methylphenol (cas: 499-75-2) belongs to alcohols. The oxygen atom of the strongly polarized O―H bond of an alcohol pulls electron density away from the hydrogen atom. This polarized hydrogen, which bears a partial positive charge, can form a hydrogen bond with a pair of nonbonding electrons on another oxygen atom. Secondary alcohols are easily oxidized without breaking carbon-carbon bonds only as far as the ketone stage. No further oxidation is seen except under very stringent conditions.HPLC of Formula: 499-75-2

And the article was included in Organic & Biomolecular Chemistry in 2014.SDS of cas: 60549-26-0 This article mentions the following:

A new strategy for the synthesis of highly substituted benzofurans, e.g., I (X-rays single crystal structure shown), from meta-substituted hydroxybenzenes and alkynes via a rhodium(III)-catalyzed activation of a sterically hindered C-H bond is demonstrated. A possible mechanism involving dual directing group assisted ortho C-H bond activation is proposed. In the experiment, the researchers used many compounds, for example, 3-Hydroxy-5-methylbenzaldehyde (cas: 60549-26-0SDS of cas: 60549-26-0).

3-Hydroxy-5-methylbenzaldehyde (cas: 60549-26-0) belongs to alcohols. Alcohols are weak acids. The most acidic simple alcohols (methanol and ethanol) are about as acidic as water, and most other alcohols are somewhat less acidic. The most common reactions of alcohols can be classified as oxidation, dehydration, substitution, esterification, and reactions of alkoxides.SDS of cas: 60549-26-0

New pleconaril and [(biphenyloxy)propyl]isoxazole derivatives with substitutions in the central ring exhibit antiviral activity against pleconaril-resistant coxsackievirus B3 was written by Schmidtke, Michaela;Wutzler, Peter;Zieger, Romy;Riabova, Olga B.;Makarov, Vadim A.. And the article was included in Antiviral Research in 2009.Quality Control of 4-Hydroxy-3-methylbenzonitrile This article mentions the following:

Amino acid 1092 (AA1092) in capsid protein 1 of coxsackievirus B3 (CVB3) is located in close vicinity to the central phenoxy group of capsid binders (i.e. pleconaril). Whereas isoleucine is associated with drug susceptibility, leucine and methionine confer resistance to pleconaril. In the present study, novel analogs with different substitutions in the central phenoxy group were synthesized to study their influence on anti-CVB3 activity with the aim to overcome pleconaril resistance. Two [(biphenyloxy)propyl]isoxazoles and pleconaril were synthesized without Me groups in the central phenoxy ring using Suzuki coupling reaction and tested for antiviral activity against the pleconaril-resistant CVB3 Nancy. Furthermore, pleconaril with 3-Me, 3-methoxy, 3-bromine, 2,3-di-Me in the central ring as well as the external rings in meta position were synthesized for structure-activity relationship anal. with CVB3 variants containing leucine, methionine or isoleucine at position 1092, other coxsackieviruses B (CVB) as well as several rhinoviruses. The results demonstrate a high impact of substituents in the central ring of capsid inhibitors for anti-enteroviral activity. Pleconaril resistance of CVB3 based on Leu1092 or Met1092 was overcome by unsubstituted analogs or by monosubstitution with 3-Me as well as 3-bromine in the central Ph. The 3-bromine derivative inhibited a broad spectrum of CVB and rhinoviruses. In the experiment, the researchers used many compounds, for example, 4-Hydroxy-3-methylbenzonitrile (cas: 15777-70-5Quality Control of 4-Hydroxy-3-methylbenzonitrile).

1-Octen-3-ol is formed from its primeveroside after mechanical wounding of soybean leaves was written by Ntoruru, Juliano Mwenda;Ohnishi, Toshiyuki;Katsumata, Fumiya;Koeduka, Takao;Matsui, Kenji. And the article was included in Plant Molecular Biology in 2022.Reference of 3391-86-4 This article mentions the following:

Hydrolysis of 1-octen-3-yl β-primeveroside implemented by a system with high structure-specificity is accountable for the rapid formation of 1-octen-3-ol from soybean leaves after mech. wounding. 1-Octen-3-ol is a volatile compound ubiquitous in fungi; however, a subset of plant species also has the ability to form 1-octen-3-ol. Owing to its volatile nature, it has been anticipated that 1-octen-3-ol is associated with the effort of the emitter to control the behavior of the surrounding organisms; however, its ecol. significance and the enzymes involved in its biosynthesis have not been fully elucidated, particularly in plants. We previously found that soybean (Glycine max) seeds contain 1-octen-3-yl β-primeveroside (pri). To elucidate the physiol. significance and the biosynthesis of 1-octen-3-ol in plants, changes in the amount of 1-octen-3-yl pri during development of soybean plants was examined A high 1-octen-3-yl pri level was found in young developing green organs, such as young leaves and sepals. Treatment of soybean leaves with Me jasmonates resulted in a significant increase in the amount of 1-octen-3-yl pri; suggesting its involvement in defense responses. Although 1-octen-3-ol was below the detection limit in intact soybean leaves, mech. damage to the leaves caused rapid hydrolysis of almost all 1-octen-3-yl pri to liberate volatile 1-octen-3-ol. Under the same conditions, the other glycosides, including isoflavone glycoside and linalool diglycoside, were hardly hydrolyzed. Therefore, the enzyme system to liberate aglycon from glycosides in soybean leaves should have strict substrate specificity. 1-Octen-3-yl pri might function as a storage form of volatile 1-octen-3-ol for immediate response against stresses accompanying tissue wounding. In the experiment, the researchers used many compounds, for example, Oct-1-en-3-ol (cas: 3391-86-4Reference of 3391-86-4).

Oct-1-en-3-ol (cas: 3391-86-4) belongs to alcohols. Because alcohols are easily synthesized and easily transformed into other compounds, they serve as important intermediates in organic synthesis. Grignard and organolithium reagents are powerful tools for organic synthesis, and the most common products of their reactions are alcohols.Reference of 3391-86-4

Comparative genomic analysis reveals potential pathogenicity and slow-growth characteristics of genus Brevundimonas and Description of Brevundimonas pishanensis sp. nov. was written by Huang, Zhenzhou;Yu, Keyi;Xiao, Yue;Wang, Yonglu;Xiao, Di;Wang, Duochun. And the article was included in Microbiology Spectrum in 2022.Synthetic Route of C4H10O4 This article mentions the following:

The genus Brevundimonas consists of Gram-neg. bacteria widely distributed in environment and can cause human infections. However, the genomic characteristics and pathogenicity of Brevundimonas remain poorly studied. Here, the whole-genome features of 24 Brevundimonas type strains were described. Brevundimonas spp. had relatively small genomes (3.13 ± 0.29 Mb) within the family Caulobacteraceae but high G + C contents (67.01 ± 2.19 mol%). Two-dimensional hierarchical clustering divided those genomes into 5 major clades, in which clades II and V contained nine and five species, resp. Interestingly, phylogenetic anal. showed a one-to-one match between core and accessory genomes, which suggested coevolution of species within the genus Brevundimonas. The unique genes were annotated to biol. functions like catalytic activity, signaling and cellular processes, multisubstance metabolism, etc. The majority of Brevundimonas spp. harbored virulence-associated genes icl, tufA, kdsA, htpB, and acpXL, which encoded isocitrate lyase, elongation factor, 2-dehydro-3-deoxyphosphooctonate aldolase, heat shock protein, and acyl carrier protein, resp. In addition, genomic islands (GIs) and phages/prophages were identified within the Brevundimonas genus. Importantly, a novel Brevundimonas species was identified from the feces of a patient (suffering from diarrhea) by the analyses of biochem. characteristics, phylogenetic tree of 16S rRNA gene, multilocus sequence anal. (MLSA) sequences, and genomic data. The name Brevundimonas pishanensis sp. nov. was proposed, with type strain CHPC 1.3453 (= GDMCC 1.2503T = KCTC 82824T). Brevundimonas spp. also showed obvious slow growth compared with that of Escherichia coli. Our study reveals insights into genomic characteristics and potential virulence-associated genes of Brevundimonas spp., and provides a basis for further intensive study of the pathogenicity of Brevundimonas. In the experiment, the researchers used many compounds, for example, (2R,3S)-rel-Butane-1,2,3,4-tetraol (cas: 149-32-6Synthetic Route of C4H10O4).

(2R,3S)-rel-Butane-1,2,3,4-tetraol (cas: 149-32-6) belongs to alcohols. The oxygen atom of the strongly polarized O―H bond of an alcohol pulls electron density away from the hydrogen atom. This polarized hydrogen, which bears a partial positive charge, can form a hydrogen bond with a pair of nonbonding electrons on another oxygen atom. Secondary alcohols are easily oxidized without breaking carbon-carbon bonds only as far as the ketone stage. No further oxidation is seen except under very stringent conditions.Synthetic Route of C4H10O4
