In vitro: GLPG1690 (Ziritaxestat) shows no CYP3A4 TDI and decreases hERG inhibitory activity with IC50 of 15 μM in manual patch clamp assay.
In vivo: GLPG1690 (Ziritaxestat) inhibits ATX-induced LPA 18:2 production in mouse, rat, and healthy donor plasma in a concentration-dependent manner, with IC50 values of 418 nM, 542 nM, and 242 nM, respectively. GLPG1690 displays improved pharmacokinetic properties, with a low plasma clearance and high bioavailability in mouse and rat. The good pharmacokinetic profile is further confirmed in dog, with GLPG1690 showing low plasma clearance (0.12 L/h/kg) and a high bioavailability (63%).

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
