Govaniadine (1), a tetrahydroprotoberberine-type alkaloid, is one of the main active constituent isolated fromCorydalis govanianaWall., Papaveraceae, with several biological activities: antinociceptive, anti-urease, and leishmanicidal. Some articles reporting tetrahydroprotoberberine and structurally related alkaloids cytotoxicity prompted us to evaluate the influence of compound1on cellular viability in two different cell lines: human hepatoma carcinoma (HepG2) and human embryonic kidney (HEK-293T) and its permeation across the human colon carcinoma cell line (Caco-2). Cellular viability reduction of compound1was observed between 30 and 100 mu M (HepG2) and between 70 and 100 mu M (HEK-293T). However, the effects were weaker than those in the positive controls (T-2 toxin and camptothecin). Prior to proceed the transport studies, a method for compound1quantification in Hank's Balanced Salt Solution medium was developed and validated by LC-MS/MS. The two calibration curves were linear over the concentration range of 6.3-200 nM and 0.2-10 mu M. The apparent permeability coefficient for absorptive transport was 20.6 +/- 3.9 x 10(-6) cm/s, indicating compound1crossed the cell monolayer by passive diffusion and it was not subjected to active efflux.
