Amycolatopsin A is a 20-membered macrolide, that can be isolated from a strain of the rare actinomycete Amycolatopsis sp. MST‐108494. Amycolatopsin A shows antimycobacterial activity against Mycobacterium bovis (BCG) and M. tuberculosis (H37Rv) with IC50 values of 0.4 μM and 4.4 μM, respectively[1].
Biological Activity
Amycolatopsin A is a macrolide polyketide originally isolated from Amycolatopsis that has antimycobacterial and anticancer activities.1 It is active against M. bovis and M. tuberculosis (IC50s = 0.4 and 4.4 μM, respectively) but not B. subtilis, S. aureus, E. coli, or P. aeruginosa (IC50s = >30 μM for all). Amycolatopsin A is cytotoxic to SW620 colorectal and NCI H460 lung cancer cells (IC50s = 0.08 and 1.2 μM, respectively).
