Description
Curator's Comment: https://www.ncbi.nlm.nih.gov/pubmed/27876600 https://www.ncbi.nlm.nih.gov/pubmed/27373660

Helvolic acid is a mycotoxin with antibacterial activity that shows broad activity against Gram positive and negative bacteria. For example Helvolic acid showed potent inhibitory effects against Staphylococcus aureus and Pseudomonas aeruginosa with MIC (minimum inhibitory concentration) values of 5.8 and 4.6ug/mL, respectively. It is a steroidal triterpene that is an inhibitor of the protein biosynthesis through archeal EF-2 (elongation factor 2). Shows antioxidant effects. Helvolic acid also showed in vitro antitrypanosomal activity against Trypanosoma brucei brucei. It showed inhibitory activity against Candida albicans and Plasmodium falciparum.

Originator

Curator's Comment: Helvolic Acid Helvolic acid was initially known also as fumigacin, it was isolated by Waksman et al. (1943)

Sample Use Guides

Doses of 10 and 20 mg/kg/day helvolic acid did not exert significant antitumor activity. Co-administration of 10 mg/kg/day helvolic acid and 20 mg/kg/day cyclophosphamide (CTX) - showed promising antitumor activity
Route of Administration: Oral
Helvolic acid was shown to inhibit C. albicans with MIC 31.5 ug/mL
