Sorbic acid
Catalog No: CFN90061
Sorbic acid is important food preservatives and powerful fungistatic agents, it inhibits various bacteria, including sporeformers, at various stages of their life cycle (germination, outgrowth and cell division). Sorbic acid is a more potent uncoupler of the membrane potential than acetic acid, the effect may also slow the rate of ATP synthesis significantly and may thus (partially) explain Sorbic acid's effectiveness.
Demethylzeylasteral
Catalog No: CFN90136
Demethylzeylasteral exhibits strong inhibition towards UDP-glucuronosyltransferase (UGT) 1A6 and 2B7, and the inhibition kinetic parameters (Ki) are calculated to be 0.6 uM and 17.3 uM for UGT1A6 and UGT2B7, respectively. Demethylzeylasteral has antimicrobial, strong immunosuppressive, and antifertility activities; it concentration-dependently and in a partially reversible manner can inhibit the Ca(2+) current in spermatogenic cells with an IC(50) of 8.8 microg/ml, and it also can inhibit significantly the sperm acrosome reaction initiated by progesterone.
