(3β,20E)-24-Norchola-5,20(22)-diene-3,23-diol is a steroid-based allylic alcohol.

Crustecdysone (Hydroxyecdysone) is a steroid hormone that regulates the processes of molting or ecdysis in insects.

TAN 420E is a bacterial metabolite originally isolated from Streptomyces. It scavenges 2,2-diphenyl-1-picrylhydrazyl radicals in a cell-free assay (IC50 = 1.3 μM) and reduces thiobarbituric acid reactive substances (TBARS) in rat liver microsomes by 72% when used at a concentration of 100 μg/ml. TAN 420E is active against B. brevis, B. cereus, M. flavus, and S. aureus (MICs = 50-100 μg/ml). It is cytotoxic to P388 and KB lymphocytic leukemia cells (EC50s = 0.022 and 0.3 μg/ml, respectively).

Pseudoginsenoside Rh2 has cytotoxicity, it induces mitochondrial apoptosis in A549 cells and is responsible for excessive activation of the Ras/Raf/ERK/p53 pathway. (20Z) -Pseudoginsenoside Rh2 and (20E)-Pseudoginsenoside Rh2 have antioxidative activity.

LDHA/PDKs-IN-1 (compound 20e) is a highly effective dual inhibitor of PDKs and LDHA, displaying IC50 values of 0.8 μM and 0.15 μM, respectively. It significantly suppresses A549 cell proliferation (EC50 = 13.2 μM), reduces lactate formation, and enhances oxygen consumption. This compound holds great promise for cancer research [1].

Ecdysone is a major steroid hormone in insects and herbs. Ecdysone triggers mineralocorticoid receptor activation and induces cellular apoptosis. Ecdysone signaling through Ecdysone receptor isoform B1 is required cell autonomously for the muscle death.
