The hepatic organic anion transporting polypeptides (OATPs) influence the pharmacokinetics of several drug classes and are involved in many clinical drug-drug interactions. Predicting potential interactions with OATPs is, therefore, of value. Here, we developed in vitro and in silico models

Previously, the steroid hormone progesterone has been demonstrated to stimulate OATP2B1-mediated transport of estrone-3-sulphate (E(1)S), dehydroepiandrosterone sulphate (DHEAS) and pregnenolone sulphate (PS), which may influence the uptake of precursor molecules for steroid hormone synthesis. However, it is unclear whether OATP2B1
