BI99179 is a potent and selective type I fatty acid synthase (FAS) inhibitor with an IC50 of 79 nM. BI 99179 exhibits significant exposure (both peripheral and central) upon oral administration in rats[1].
BI 99179 is potent in the mouse hypothalamic N-42 cell with an IC50 of 0.6 μM. BI 99179 shows no significant LDH release in the cytotoxicity assay up to 30 μM[1].
BI 99179 has a super pharmacokinetic profile in male Han/Wistar rats (oral application of 4 mg/kg)with half life (t1/2) of 3.0 h[1].
