inhibition of alpha-chymotrypsin in the presence of Zn2+
1,2-propanediol
residual activity of bovine pancreatic alpha-chymotrypsin is studied in water/1,2-propanediol mixtures in the entire range of water content at 25°C. The degree of stabilization/ destabilization of alpha-chymotrypsin depends strongly on the water content in organic solvent. At high water content, the residual activity values are higher than 100%. At low water content, the residual catalytic activity is about 90-95%, compared with that observed after incubation in pure water

the presence of substituents on benzene ring reduces the inhibitory potential of benzoxazinone. The increased inhibitory potential due to fluoro group at phenyl substituent is observed followed by chloro and bromo substituents. Compounds with strong electron donating or withdrawing groups on phenyl substituent, show a good inhibitory potential at ortho > meta > para position. Kinetic studies show diverse types of inhibition, except uncompetitive-type inhibition

cyanopeptolin
Arg-containing cyanopeptolins inhibit trypsin at low IC50 values (0.00024-0.00026 mM)and show mild activity against chymotrypsin (IC50 0.0031-0.0038 mM), while Tyr-containing cyanopeptolins are selectively and potently active against chymotrypsin (IC50 0.00026 mM). Neither of the cyanopeptolins are active against thrombin, elastase or protein phosphatase 1. Two cyanopeptolins (CP962 and CP985) have no cytotoxic effects on MCF-7 breast cancer cells. Strong and selective activity of the new cyanopeptolin variants makes them potential candidates for the development of drugs against metabolic disorders and other diseases

as the wild-type inhibitor, the recombinant inhibitor, while acting as a strong subtilisin inhibitor, is much less efficient against alpha-chymotrypsin. Mutant E49S of the wheat subtilisin/chymotrypsin inhibitor shows a limited anti-chymotrypsin activity. Mutants E49P, Y50G and M48P/E49G are inactive against alpha-chymotrypsin
