Comparative anti-glycation and alpha-glucosidase inhibition studies of microbial transformed compounds of dydrogesterone

Anti-glycation and alpha-glucosidase inhibition activities of microbial transformed compounds of dydrogesterone [1]; 20R-hydroxy-9 beta,10 alpha-pregna-4,6-diene-3-one [2], 17 beta-hydroxy-9 beta,10 alpha-androsta-4,6-diene-3-one [3] and 9 beta,10 alpha- androsta-4,6-diene-3,17-dione [4] were evaluated. Compounds 1 and 4 showed potent alpha-glucosidase inhibitory activities, while 2 and 3 were found to be weak inhibitors, whereas anti-glycation activities of 1-4 were not observed
