Electric Literature of 92-30-8, Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. 92-30-8, Name is 2-(Trifluoromethyl)-10H-phenothiazine, SMILES is FC(C(C=C1N2)=CC=C1SC3=C2C=CC=C3)(F)F, belongs to thiazines compound. In a article, author is Niu Liping, introduce new discover of the category.
Synthesis of the Fused Tetracyclic Thiazinan-4-one Derivatives and Their Anti-tumor Activitiy
The benzothiazin-4-one intermediates were prepared by the one-pot three-components condensation from the N-Boc-L-prolinal 1, amino acid ethyl/methyl ester hydrochlorides 2a similar to 2d, and mercaptobenzoic acids 3a similar to 3b. After removal of Boc, the target novel fused tetracyclic thiazinan-4-one derivatives 6 similar to 11 were afforded by the intramolecular cyclo- amidation reaction. The absolute configurations of the newly generated chiral carbon (1-C) were determined by the coupling constants of H-1 and H-2 and the X-ray crystallographic structures. The tetracyclic alkaloids were examined for their anti-proliferative activity against Hela and A549 tumor cells. The results showed that some compounds could moderately inhibit the growth of Hela cells, and among them, (13aR, 13bR)-1,2,3,13b-tetrahydrobenzo[e]pyrrolo[2′, 1′: 3,4] pyrazino[2,1b][1,3] thiazine-5,8(6H, 13aH)-dione (6b) was the best one with the IC50 value of 9.50 mu mol/L. However, all the compounds showed no anti-tumor activity against A549.
Electric Literature of 92-30-8, Because enzymes can increase reaction rates by enormous factors and tend to be very specific, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 92-30-8.
