Objective: The aim of this research work was to characterize the metabolism of S002-333, (2-(4'-methoxy-benzenesulfonyl)-2,3,4,9-tetrahydro-1H-pyrido (3,4-b) indole-3-carboxylic acid amide) and its enantiomers, S004-1032 (R-form) and S007-1558 (S-form) in pooled human liver microsomes (PHLM) and pooled liver microsomes (LM) of rat (RLM), rabbit (RABLM), dog (DLM) and monkey (MLM). Another objective of this study was to identify suitable surrogate species to humans for further development of lead candidates.

Method: In vitro metabolic stability and metabolite identification of S002-333 and enantiomers were carried out in PHLM and LM of various species.

Various 2,4-dimethoxyphenylsemicarbazones were synthesized starting from 2,4-dimethoxyaniline via a phenylcarbamate intermediate. The structures were confirmed by spectral and elemental analyses. The anticonvulsant activity of the synthesized compounds was established after intraperitoneal administration in three seizure models in mice which include maximal electroshock seizure, subcutaneous pentylenetetrazole, and subcutaneous strychnine-induced seizure screens.
