A new series of benzimidazole bearing pyridine derivatives were synthesized by condensation of 1,2-phenylenediamine with 2-oxo-1,2-dihydro-pyridine-3-carboxylic acid derivative 2 in phosphoric acid to give 3-(1Hbenzo[ d]imidazol-2-yl)-pyridin-2(1H)-one derivative 3. Compound 3 on further reaction with a mixture of phosphorus oxychloride and phosphorus pentachloride gave 2-(2-chloro-) pyridin-3-yl)-1H-benzo[d] imidazole derivative 4. Moreover, 4 were reacted with different amines to give 3-(1H-benzo[d]imidazol-2-yl)-N-(substituted) pyridin-2-amine derivatives 5a-c. Meanwhile, N-(N-(substituted) sulfamoyl) pyridin-3-yl)-1H-benzo[d]imidazole-1-carboxamide derivatives 7a,b were synthesized by reaction of 5c with chlorosulfonyl isocyanate to give 2-(pyridin-3-yl)-1H-benzo [d]imidazole-1-carbonyl) sulfamoyl chloride derivative followed by reaction of the latter with different amines. On the other hand, upon treatment compound 4 with hydrazine hydrate gave the hydrazide derivative 8. The reaction of compound 8 with different alkyl/arylisothiocyanates gave the corresponding thiosemicarbazide derivatives 9a-d, while their cyclo condensation reaction with ethyl chloro acetate gave the corresponding thiazolidin-4-one derivatives 10a-c. Moreover, condensation of 10a,c with aromatic aldehydes afforded the corresponding 5-arylidine-thiazolidin-4-one derivatives 11a,b. Cytotoxic evaluation of some of the newly synthesized compounds against human breast carcinoma cell line MCF-7 revealed that, these compounds showed promising activity compared with Doxorubicin as positive control.

New Advances in Chemical Research in 2021. Reactions catalyzed within inorganic and organic materials interfaces commonly occur at high coverage, causing turnover rates to depend strongly on interfacial structure and composition, In a patent, 76186-04-4, name is (S)-4-Isopropylthiazolidine-2-thione, introducing its new discovery. Application of 76186-04-4

Enantioselective approaches to the construction of four complex building blocks of the structurally intricate marine macrolide known as spongistatin 1 are presented. The first phase of the synthetic effort relies on a practical approach to a desymmetrized, enantiomerically pure spiroketal ring system incorporating rings A and B. Concurrently, the C17-C28 subunit, which houses one-fifth of the stereogenic centers of the target in the form of rings C and D, was assembled via a composite of stereocontrolled aldol condensations. Once arrival at the entire C1-C28 sector had been realized, routes were devised to provide two additional highly functionalized sectors consisting of C29-C44 and C38-C51. A series of subsequent transformations including cyclization of the E ring and hydroboration to afford the B-alkyl intermediate for the key Suzuki coupling to append the side chain took advantage of efficient stereocontrol. Ultimately, complete assembly and functionalization of the western EF sector of spongistatin was thwarted by an inoperative Suzuki coupling step intended to join the side chain to the C29-C44 sector, and later because of complications due to protecting groups, which precluded the complete elaboration of the late stage C29-C51 intermediate.

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.

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.
