Ecdysteroids as Potent Enzyme Inhibitors and Verification of Their Activity Using In Vitro and In Silico Docking Studies

Life, 2022
Ecdysteroids represent arthropods’ steroidal hormones, and they exist in about 5–6% of plant species. In this study, the enzyme inhibitory activity of 20 ecdysteroids was assessed for the first time via determining their inhibition versus ...
