Eleutherol is a naphthalene isolated from E. americana with antifungal activities. Eleutherol is against yeasts Candida albicans, C. tropicalis, Saccharomyces cerevisiae and Cryptococcus neoformans with MIC values between 7.8 μg/mL and 250 μg/mL. Eleutherol inhibits α-glucosidase function with an IC50>1.00 mM.

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.
