Leoidin

Leoidin is a depsidone originally isolated from L. gangaleoides that has antibacterial and enzyme inhibitory activities.{52316,52317,48817} It is active against the bacteria E. faecalis, H. influenzae, M. catarrhalis, S. aureus, and S. pneumoniae (MICs = 8, 32, 1, 128, and 64 µg/ml, respectively).{52317} Leoidin inhibits phenylalanyl-tRNA synthetase (PheRS) isolated from P. aeruginosa (IC50 = 42 µM). It also inhibits organic anion-transporting polypeptide 1B1 (OATP1B1) and OATP1B3 with Ki values of 0.08 and 1.84 µM, respectively, in CHO cells expressing the human transporters.{48817}
