Herquline A is an alkaloid fungal metabolite originally isolated from P. herquei. It inhibits cell death induced by influenza A strain A PR 8 34 in MDCK cells with an IC50 value of 10 μg ml and inhibits viral replication in a plaque assay in a concentration-dependent manner. Herquline A also inhibits platelet aggregation induced by ADP and platelet-activating factor (PAF) in vitro (IC50s = 180 and 240 μM, respectively).
Telmisartan acyl-β-D-glucuronide is a major metabolite of the angiotensin II receptor antagonist telmisartan . It does not bind human serum albumin and is cleared from rat plasma with a clearance rate of 180ml/min/kg following intravenous administration.
Lucialdehyde C (Lucidal) exhibits potent cytotoxicity against LLC, T-47D, Sarcoma 180, and Meth-A tumor cells with ED(50) values of 10.7, 4.7, 7.1, and 3.8 microg/ml, respectively.
