Irilone has immunomodulatory, and α-amylase inhibitory activities, it exhibits the selective inhibition toward CYP3 A4 rather than other major human CYPs.

N-methylnicotinamide is a metabolite of niacin (or nicotinamide) and is commonly found in human urine. However low levels of urinary excretion of N-methylnicotinamide indicates niacin deficiency. In patients with liver cirrhosis nicotinamide methylation is increased leading to a rise in urinary N-methylnicotinamide. N-methylnicotinamide has been found to be a microbial metabolite.

HeE1-2Tyr, a pyridobenzothiazole compound, is a flavivirus RNA dependent RNA polymerases (RdRp) inhibitor. It significantly inhibits West Nile, Dengue and SARS-CoV-2 RdRps (IC50 of 27.6 μM) activity in vitro.
