New Advances in Chemical Research, May 2021. Related Products of 5908-62-3, Redox catalysis has been broadly utilized in electrochemical synthesis due to its kinetic advantages over direct electrolysis. 5908-62-3, Name is 1,1-Dioxo-isothiazolidine, molecular formula is C3H7NO2S. In a Article，once mentioned of 5908-62-3

The telomerization of several acrylamides, most containing chiral auxiliary groups, was investigated. The first-formed stereogenic center in the n = 2 telomer (the penultimate center) has a significant effect on the configuration of the second (ultimate) center in the product. The penultimate chiral center of oxazolidine-derived acrylamides directs the configuration of the ultimate center such that the erythro n = 2 product is preferred. Sultam-substituted acrylamides preferentially lead, on the other hand, to threo products or give products with little stereoselectivity.

Chemical Research Letters, May 2021. An article , which mentions SDS of cas: 2682-49-7, molecular formula is C3H5NOS. The compound – Thiazolidin-2-one played an important role in people’s production and life., SDS of cas: 2682-49-7

Background: Medicinal interest has focused on beta-carbolines as anticancer agents. Methodology/Results: Several beta-carbolines were designed, synthesized and evaluated for their cytotoxic activity against MCF-7 and A-549 cancer cell lines using MTT assay. Compounds 13a, 13c, 13d and 20a were the most promising showing high selectivity indices. Compounds 13c and 20a showed potent inhibition of topoisomerase (topo-I) and kinesin spindle protein (KSP/Eg5 ATPase) which was confirmed by their docking results into the active site of both enzymes. In silico physicochemical calculations predicted that compounds 13a, 13d and 20a obeyed Lipinski’s rule of five. Conclusion: Compounds 13c and 20a are multitarget anticancer leads that act as potent inhibitors for both topo-I and/or KSP ATPase.
