(author), TNO Kwaliteit van Leven (author)PLD-118 is a novel, oral antifungal drug, under development for the treatment of Candida infections. Possible metabolism of PLD-118 by rat, dog and human S9 liver homogenates and inhibition of human cytochrome P450 (CYP) enzymes were investigated. PLD-118 (10 and 100 μm) incubated for 0-60 min with S9 fractions and NADPH was determined by HPLC,...article 2005

(author), TNO Voeding (author)The effect of cimetidine on the metabolism of zaleplon (ZAL) in human liver subcellular fractions and precision-cut liver slices was investigated. 2. ZAL was metabolized to a number of products including 5-oxo-ZAL (M2), which is known to be formed by aldehyde oxidase, N-desethyl-ZAL (DZAL), which is known to be formed by CYP3A forms, and N...article 2002

(author), Centraal Instituut voor Voedingsonderzoek TNO (author)The effects of the mycotoxin fumonisin B1 (FB1) on the hepatic cytochrome P450 system were investigated in male rats dosed daily by oral gavage with 3 mg FB1 per kg body weight for 9 consecutive days. FB1 treatment resulted in a reduced weight gain. At the same time, CYP2E activity was increased, which is considered to mark the metabolic changes...article 2000
