Sparsentan (RE-021; BMS-346567; PS433540; DARA-a) is a highly potent dual angiotensin II and endothelin A receptor antagonist with Kis of 0.8 and 9.3 nM, respectively.
Sparsentan dose dependently antagonizes the angiotensin II-induced pressor response with an ED50 value of 0.8 µmol/kg iv and 3.6 µmol/kg po. Sparsentan also shows efficacious and long acting in the big ET-1-induced pressor model. Sparsentan causes a significant lowering of blood pressure at the lowest dose tested (10 µmol/kg/day) in spontaneously hypertensive rats. Sparsentan shows good oral bioavailability in rats, dogs, and monkeys, averaging 40%, 86%, and 21% F, respectively. At 100 µmol/kg/day, Sparsentan reduces the blood pressure from 170 to less than 100 mmHg during the course of the drug's pharmacokinetic duration. Sparsentan at 100 µmol/kg/day essentially converts the spontaneously hypertensive rats into normotensive rats during the course of its pharmacokinetic duration[1].
