Popis: This study reports the pharmacokinetics and tissue distribution of a novel histone deacetylase and DNA methyltransferase inhibitor, psammaplin A (PsA), in mice. PsA concentrations were determined by a validated LC-MS/MS assay method (LLOQ 2 ng/mL). Following intravenous injection at a dose of 10 mg/kg in mice, PsA was rapidly eliminated, with the average half-life (t(1/2, λn)) of 9.9 ± 1.4 min and the systemic clearance (CL(s)) of 925.1 ± 570.1 mL/min. The in vitro stability of PsA was determined in different tissue homogenates. The average degradation t(1/2) of PsA in blood, liver, kidney and lung was found relatively short (≤ 12.8 min). Concerning the in vivo tissue distribution characteristics, PsA was found to be highly distributed to lung tissues, with the lung-to-serum partition coefficients (K(p)) ranging from 49.9 to 60.2. In contrast, PsA concentrations in other tissues were either comparable with or less than serum concentrations. The high and specific lung targeting characteristics indicates that PsA has the potential to be developed as a lung cancer treatment agent.
