Recently I am researching about BIOLOGICAL EVALUATION, Saw an article supported by the Council of Scientific and Industrial Research (CSIR), New Delhi, IndiaCouncil of Scientific & Industrial Research (CSIR) – India [DST-SERB/EEQ/2017/095]. HPLC of Formula: C15H12O. Published in PERGAMON-ELSEVIER SCIENCE LTD in OXFORD ,Authors: Vanaparthi, S; Bantu, R; Jain, N; Janardhan, S; Nagarapu, L. The CAS is 94-41-7. Through research, I have a further understanding and discovery of Chalcone

A new series of 1,2,3-triazole tethered chalcone acetamide derivatives (7a-c & 8a-r) have been synthesized in excellent yields and their structures were determined by analytical and spectral (FT-IR, H-1 NMR, C-13 NMR HRMS) studies. The newly synthesized derivatives were evaluated for their cytotoxic activity against four human cancer cell lines, such as HeLa (Human cervical cancer), A549 (Human alveolar adenocarcinoma), MCF-7 (Human breast adenocarcinoma) and SKNSH (Human brain cancer). Among them, compound 7c exhibited good anti-proliferation activity with HeLa (IC50 7.41 + 0.8 mu M), SKNSH (IC50 8.68 + 1.1 mu M), MCF-7 (IC50 9.76 + 1.3 mu M) and MDA-MB-231, while compounds 7a and 7b showed promising anti-proliferation against above four human cancer cell lines with IC50 7.95-11.62 mu M, respectively, compared with the standard drug Doxorubicin. We explored the probable key active site and binding mode interactions in HDAC8 (PDB ID:3SFH) and EHMT2 (PDB ID:3K5K) proteins. The docking results are complementary to the experimental observations.

Several hundred (396) compounds from New Zealand flora with medicinal properties were analyzed for their physicochemical properties. It was found that approximately 10% fulfilled all the requirements to be considered to be lead-like, over half of the compounds were deemed to be in the drug-like space and approximate to 75% were in the known drug space. These results indicate the presence of a significant proportion of compounds that are of particular interest to pursue as potential lead compounds or therapeutics. Additionally, compound classes were analyzed separatelymost carbonyl-containing compounds (aldehydes, ketones, esters and lactones), along with phenols were the most lead-like compounds, which also displayed very good proportions in the drug-like and known drug space. The information presented herein can be harnessed and utilized in future work, through focussing on the compounds and compound classes that exhibit high-levels of lead-likeness for further development.

Acyl radicals have been generated from alpha-keto acids using inexpensive and commercially available 2-chloro-thioxanthen-9-one as the photoredox catalyst under visible light illumination. These reactive species added to olefins or coupled with aryl halides via a bipyridyl-stabilized Ni(II) catalyst, enabling easy access to a diverse range of ketones. This reliable, atom-economical, and eco-friendly protocol is compatible with a wide range of functional groups.

A series of novel chalcone derivatives containing a thiophene sulfonate group were designed and synthesized. The structures of all title compounds were determined by H-1-NMR, C-13-NMR and HRMS. Antibacterial bioassays indicated that, compound 2l demonstrated excellent antibacterial activities against Xanthomonas axonopodis pv. citri (Xac), with an EC50 value of 11.4 mu g mL(-1), which is significantly superior to those of bismerthiazol (BT) (51.6 mu g mL(-1)) and thiodiazole-copper (TC) (94.7 mu g mL(-1)). Meanwhile, the mechanism of action of compound 2l was confirmed by using scanning electron microscopy (SEM). In addition, compound 2e showed remarkable inactivation activity against Tobacco mosaic virus (TMV), with an EC50 value of 44.3 mu g mL(-1), which was superior to that of ningnanmycin (120.6 mu g mL(-1)). Microscale thermophoresis (MST) also showed that the binding of compounds 2e and 2h to Tobacco mosaic virus coat protein (TMV-CP) yielded K-d values of 0.270 and 0.301 mu mol L-1, which are better than that of ningnanmycin (0.596 mu mol L-1). At the same time, molecular docking studies for 2e and 2h with TMV-CP (PDB code: ; 1EI7) showed that the compound was embedded well in the pocket between the two subunits of TMV-CP in each case. These results suggested that chalcone derivatives containing a thiophene sulfonate group may be considered as activators in the design of antibacterial and antiviral agents.

Two chiral polymers based on binaphthol(BINOL) were synthesized. The polymer can be used as a chiral inducer to coordinate with ZnEt2 to form a recoverable self-supporting catalyst, which could be used in the asymmetric catalytic reaction of alpha, beta-unsaturated ketones. The target products of high yield and good enantioselectivity(e.e. value up to 99%) can be obtained under mild conditions. The catalytic activity was not reduced significantly after 4 or 5 cycles of recovery of the recovered polymers.
