The article was 《Potent noncovalent inhibitors of the main protease of SARS-CoV-2 from molecular sculpting of the drug perampanel guided by free energy perturbation calculations》. The article mentions the following:

Starting from our previous finding of 14 known drugs as inhibitors of the main protease (Mpro) of SARS-CoV-2, the virus responsible for COVID-19, we have redesigned the weak hit perampanel to yield multiple noncovalent, nonpeptidic inhibitors with ca. 20 nM IC50 values in a kinetic assay. Free-energy perturbation (FEP) calculations for Mpro-ligand complexes provided valuable guidance on beneficial modifications that rapidly delivered the potent analogs. The design efforts were confirmed and augmented by determination of high-resolution X-ray crystal structures for five analogs bound to Mpro. Results of cell-based antiviral assays further demonstrated the potential of the compounds for treatment of COVID-19. In addition to the possible therapeutic significance, the work clearly demonstrates the power of computational chem. for drug discovery, especially FEP-guided lead optimization. The experimental part of the paper was very detailed, including the reaction process of 3,3,3-Trifluoropropan-1-ol(cas: 2240-88-2Computed Properties of C3H5F3O)

3,3,3-Trifluoropropan-1-ol(cas: 2240-88-2) is a important organic intermediate. It can be used in agrochemical, pharmaceutical and dyestuff field.Computed Properties of C3H5F3O

Application In Synthesis of (R)-Oxiran-2-ylmethanolOn March 19, 2021, Bold, Christian P.; Klaus, Cindy; Pfeiffer, Bernhard; Schurmann, Jasmine; Lombardi, Rafael; Lucena-Agell, Daniel; Diaz, J. Fernando; Altmann, Karl-Heinz published an article in Organic Letters. The article was 《Studies toward the Synthesis of an Oxazole-Based Analog of (-)-Zampanolide》. The article mentions the following:

Studies are described toward the synthesis of an oxazole-based analog I of (-)-zampanolide. Construction of (-)-dactylolide analog 22 was achieved via alc. II and acid III through esterification and Horner-Wadsworth-Emmons (HWE)-based macrocyclization; however, attempts to attach (Z,E)-sorbamide to I proved unsuccessful. The C(8)-C(9) double bond of the macrocycle was prone to migration into conjugation with the oxazole ring, which may generally limit the usefulness of zampanolide analogs with aromatic moieties as tetrahydropyran replacements. The experimental process involved the reaction of (R)-Oxiran-2-ylmethanol(cas: 57044-25-4Application In Synthesis of (R)-Oxiran-2-ylmethanol)

Recommanded Product: Octadecan-9-olOn November 30, 2014 ,《A general method for the synthesis of enantiopure aliphatic chain alcohols with established absolute configurations. Part 2, via catalytic reduction of acetylene alcohol MαNP esters》 appeared in Tetrahedron: Asymmetry. The author of the article were Akagi, Megumi; Sekiguchi, Satoshi; Taji, Hiromi; Kasai, Yusuke; Kuwahara, Shunsuke; Watanabe, Masataka; Harada, Nobuyuki. The article conveys some information:

A general method for synthesizing enantiopure (100% ee) aliphatic alcs. with established absolute configurations has been developed and applied to alcs. CH3(CH2)n-CH(OH)-(CH2)mCH3, the enantiomeric discrimination of which is the most difficult, if m = n + 1 and n is large. Racemic saturated alcs. with short chains could be directly enantioresolved as (S)-(+)-2-methoxy-2-(1-naphthyl)propionic acid [MαNP acid (I)] esters by HPLC on silica gel, and their absolute configurations were simultaneously determined by 1H NMR diamagnetic anisotropy. However, the application of this powerful MαNP ester method to alcs. with long chains was difficult, because of smaller values of the separation factor α. In such cases, the use of the corresponding acetylene alc. MαNP esters was crucial. Acetylene alc. MαNP esters were largely separated by HPLC on silica gel, and their absolute configurations were unambiguously determined by 1H NMR as reported in the Part 1 paper. The MαNP esters obtained with established absolute configurations were catalytically hydrogenated to yield saturated alc. MαNP esters. It was evidenced that no racemization occurred at the stereogenic center of the alc. moiety during catalytic hydrogenation, by the co-injection of MαNP esters in HPLC. From the MαNP esters obtained, enantiopure (100% ee) aliphatic chain alcs. with established absolute configurations were recovered. Although the [α]D values of these alcs. were too small for the identification of the enantiomers, it was clarified that the anal. HPLC of MαNP esters is useful for identification in most cases. In the experimental materials used by the author, we found Octadecan-9-ol(cas: 591-70-8Recommanded Product: Octadecan-9-ol)

The article was titled 《Hybrids of coumarin-indole: design, synthesis and biological evaluation in Triton WR-1339 and high-fat diet induced hyperlipidemic rat models》. The information in the text is summarized as follows:

In this study, a series of coumarin-indole hybrids have been synthesized and evaluated for their lipid lowering activity. Preliminary biol. screening of the synthesized compounds was undertaken in an in vitro model of the HMG-CoA reductase enzyme, and the activity was confirmed in Triton WR-1339 induced hyperlipidemic rats. Among the hybrids, compound 26 was found to be the best as it significantly reduced the serum and hepatic lipid profiles in an HFD-fed hyperlipidemic rat model. The mechanism of action seems to be associated with the regulation of HMG-CoA reductase activity in the liver, which is in good agreement with binding mode studies. Compound 26 exhibited favorable pharmacokinetic behavior for its oral administration, which underscores the potential of this template as a new class of hypolipidemic agents. In the part of experimental materials, we found many familiar compounds, such as 5-(tert-Butyl)-4-hydroxyisophthalaldehyde(cas: 153759-59-2Recommanded Product: 153759-59-2)

The article was titled 《Isolation of Polysaccharides from Trichoderma harzianum with Antioxidant, Anticancer, and Enzyme Inhibition Properties》. The information in the text is summarized as follows:

In this work, a total of six polysaccharides were isolated from culture filtrate (EPS1, EPS2) and mycelia (IPS1-IPS4) of Trichoderma harzianum. The HPLC anal. results showed that EPS1, EPS2, IPS1, and IPS2 were composed of mannose, ribose, glucose, galactose, and arabinose. The FT-IR, 1H, and 13C NMR chem. shifts confirmed that the signals in EPS1 mainly consist of (1→4)-linked α-d-glucopyranose. EPS1 and IPS1 showed a smooth and clean surface, while EPS2, IPS2, and IPS3 exhibited a microporous structure. Among polysaccharides, EPS1 displayed higher ABTS+ (47.09 ± 2.25% and DPPH (26.44 ± 0.12%) scavenging activities, as well as higher α-amylase (69.30 ± 1.28%) and α-glucosidase (68.22 ± 0.64%) inhibition activity than the other polysaccharides. EPS1 exhibited high cytotoxicity to MDA-MB293 cells, with an IC50 of 0.437 mg/mL, and this was also confirmed by cell staining and FACS assays. These results report the physicochem. and bioactive properties of polysaccharides from T. harzianum.

Maeda, Haruka; Tsuyama, Taku; Takabe, Keiji; Kamitakahara, Hiroshi; Takano, Toshiyuki published their research in Journal of Wood Science on December 31 ,2019. The article was titled 《Preparation and properties of a coniferin enantiomer》.Safety of rel-(3R,4S,5S,6R)-6-(Hydroxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetraol The article contains the following contents:

L-Coniferin (1L), which is an enantiomer of natural coniferin (D-coniferin (1D)), was prepared from L-glucose according to the conventional method for compound 1D. The reactivity of L-glucose and its derivatives was found to be almost same as that of the corresponding D-glucose and its derivatives during the preparation for compound 1L. Compound 1L showed resistance toward enzymic hydrolysis by com. β-glucosidase from Almond. However, unlike compound 1D, compound 1L was not transported across the membrane obtained from differentiating xylem of a hybrid poplar in the present assay. The result suggested for the first time that the D-/L-configuration of the glucose moiety of coniferin is an important factor affecting coniferin transport across the membrane.

And the article was published in MedChemComm in 2016. Name: 5-(tert-Butyl)-4-hydroxyisophthalaldehyde The author mentioned the following in the article:

A series of new dihydropyrimidinone-semicarbazone hybrids were successfully synthesized by integrating regioselective multicomponent reaction with the pharmacophore hybridization approach. All the synthesized compounds were evaluated for their hLig1 inhibition potency and most of them were found to be good to moderately active. Out of the tested derivatives, compound 6f showed selective anti-proliferative activity against HepG2 cells in a dose-dependent manner with an IC50 value of 10.07 ± 1.2. It also reduced cell survival at ≤20 μM concentration Further, anal. of treated HepG2 cell lysates by western blot assay showed increased γ-H2AX levels and upregulation of p53, leading to apoptosis. In silico docking results explain the binding modes of compound 6f to the DNA-binding domain of hLig1 enzyme thereby preventing its nick sealing activity. In addition, the favorable pharmacokinetic properties suggest that this new class of hLig1 inhibitors could be promising leads for further drug development.
