Hydrolysis of the new types of iminium salts was used to synthesize O,O-dialkyl-S-(1,1-dimethyl-2-oxoethyl)dithiophosphates or 2-dialkoxythiophosphorylthio-substituted aldehydes with C isochain. Reactions of aldehydes with N-, N,N-, and O,N-nucleophiles gave new phosphorylated imines containing an acetal group at different positions, perhydro-1,3-diazol and oxazol with the diisopropoxythiophosphorylthio group in a side chain, and hydrazone of this aldehyde and diphenylphosphinylacetic acid hydrazide.

Habibi, Azadeh Ebrahim published the artcileThermostabilization of Bacillus amyloliquefaciens α-amylase by chemical crosslinking, Recommanded Product: Bis(2,5-dioxopyrrolidin-1-yl) O,O’-ethane-1,2-diyl disuccinate, the publication is Journal of Biotechnology (2006), 123(4), 434-442, database is CAplus and MEDLINE.

Chem. crosslinking of a mesophilic α-amylase from Bacillus amyloliquefaciens (BAA) was carried out. Intramol. crosslinks between Lys residues upon treatment of the enzyme with ethylene glycol bis(succinic acid N-hydroxy succinimide ester) resulted in enhancement of thermostability as indicated by irreversible thermoinactivation experiments Enhancement of thermostability coincided with a dramatic protection against aggregation, combined with a decrease in surface hydrophobicity. Deamidation, another important mechanism of irreversible thermoinactivation, was also diminished upon modification. While no significant changes in the kinetic parameters were evident, rigidification of the protein structure was suggested by CD and fluorescence studies.

Ali, Barkat published the artcileImpact of Soy-Cow’s mixed milk enzyme modified cheese on bread aroma, Synthetic Route of 111-29-5, the publication is LWT–Food Science and Technology (2022), 112793, database is CAplus.

The effect of spray-dried Soy-Cow’s mixed milk enzyme modified (SC-EM) cheese on wheat dough properties and bread aroma was evaluated at either 0.1, 0.5, 1.0, 1.5 or 2.0% (weight/weight). Significant accumulation of amino acids and peptides of dough were noted as SC-EM cheese levels increased. After baking a total of 118 volatile compounds (VCs) were identified in breads having aldehydes, alcs., esters and acids in major proportions. Higher contents of Maillard product 3-hydroxy-2-butanone, 2-methyl-1-propanol, phenylethyl alc., undecane, L-limonene, 2-pentyl furan and lipid oxidation compounds hexanoic acid Et ester, octanoic acid Et ester, decanoic acid Et ester, butanoic acid, hexanoic acid and octanoic acid were observed Isoamyl alc., lactic acid Et ester, Et sorbate and sorbic acid were the newly identified VCs. These results revealed that SC-EM cheese could be used as improver in dough and contribution to bread aroma. Thus, SC-EM cheese has been proposed to be included in fortified bakery products.

Khan, Atta Ullah published the artcileIron-doped zinc oxide nanoparticles-triggered elicitation of important phenolic compounds in cell cultures of Fagonia indica, Product Details of C8H8O3, the publication is Plant Cell, Tissue and Organ Culture (2021), 147(2), 287-296, database is CAplus and MEDLINE.

The callus cultures of Fagonia indica could prove as factories for the production of important phytochems. when triggered through different types of stress. In this study, we initiated callus cultures from healthy stem explants in the presence of iron-doped zinc oxide nanoparticles (Fe-ZnO-NPs). We performed experiments with the callus cultures of F. indica to determine the impact of Fe-ZnO-NPs in concentrations (15.62-250μg/mL) on biomass accumulation, production of important phenolic and flavonoids, and antioxidative potential. Our results showed that maximum callus biomass [Fresh weight (FW) = 13.6 g and Dry weight (DW) = 0.58 ± 0.01] was produced on day 40 when the media was supplemented with 250μg/mL Fe-ZnO-NPs. Similarly, maximum total phenolic content (268.36μg GAE/g of DW) was observed in 40 days old callus added with 125μg/mL Fe-ZnO-NPs. Maximum total flavonoid content (78.56μg QE/g of DW) was recorded in 20 days old callus grown in 62.5μg/mL Fe-ZnO-NPs containing media. Maximum total antioxidant capacity (390.74μg AAE/g of DW) was recorded in 40 days old callus with 125μg/mL Fe-ZnO-NPs treated cultures, resp. Similarly, the highest free radical scavenging activity (93.02%) was observed in callus derived from media having 15.62μg/mL Fe-ZnO-NPs. The antioxidant potential was observed to have pos. correlation with TPC (r = 0.44). HPLC anal. showed that Fe-ZnO-NPs produced compounds (e.g., Epigallocatechin gallate) that were either absent or in lesser quantities in the control group. These results showed that Fe-ZnO-NPs elicitors could increase the biomass and activate secondary metabolism in F. indica cells.

Regioregular head-to-tail 3-alkoxy-substituted polythiophenes (PTs) (with R=C₆H₁₃O- and CH₃OC₂H₄OC₂H₄O-) and poly(2,5-(3-functionalized-3,4-ethylenedioxy)bithiophene) with dodecyl and diethyleneglycol Me Et as hydrophobic and hydrophilic substituents, resp., were polymerized via a Grignard Methathesis Method (GRIM). Mol. weights were characterized by gel permeation chromatog. (GPC) and matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectroscopy, where the latter was used to obtain the end group composition UV-vis NIR spectroscopic studies showed that due to the presence of the electron donating oxygen atom, directly attached to the ring, the 3-alkoxy-substituted PTs possess a lower band gap than their alkyl analogs. The polymers self-oxidized in air and conductivity measurements revealed that further doping with I2 increases conductivity and prolongs the stability of the doped state. Poly(3-alkoxythiophenes) remain in the doped state for as long as three weeks.

Vozhdaeva, Margarita Yu. published the artcileMonitoring and statistical analysis of formation of organochlorine and organobromine compounds in drinking water of different water intakes, Product Details of C5H11BrO, the publication is Molecules (2021), 26(7), 1852, database is CAplus and MEDLINE.

The main drawback of drinking water chlorination involves the formation of quite hazardous disinfection byproducts (DBPs), represented mainly by halogenated species. Based on the authors’ monitoring data since 2002, the prevalence of chlorine over bromine in the composition of volatile DBPs was shown for the drinking water in Ufa (Russia). However, the situation was completely reversed in the case of semi-volatile DBPs. The principal goal of the present study involved rationalization of the results of the long-term monitoring. Gas chromatog.-mass spectrometry (GC-MS) was used for the qual. and quant. anal. of volatile DBPs. Identification of semi-volatile compounds was carried out with GC-MS, while gas chromatog. with an at. emission detector (GC-AED) was used for their quantification. A significant contribution of oxygen to the composition of semi-volatile compounds proves the decisive role of the dissolved organic matter oxidative destructive processes. Statistical anal. revealed notable linear correlations for trihalomethane and haloacetic acid formation vs. chlorine dose. On the contrary, halogenated semi-volatile products do not demonstrate any correlations with the water quality parameters or chlorine dose. Principal component anal. (PCA) placed them into sep. groups. The results allow for proposing that formation of the organohalogenated species involved the fast penetration of bromine into the humic matter mols. and, further, their oxidative destruction by active chlorine.
