We have investigated the protective effect of YM598, a selective endothelin type A receptor antagonist, against an endothelin-1-induced proliferation of rat mesangial cells and renal function in Otsuka Long-Evans Tokushima Fatty (OLETF) rats, an animal model of type II diabetes. YM598, but not K-8794, a selective endothelin type B receptor antagonist, inhibited the endothelin-1-induced proliferation of cultured mesangial cells derived from intact Wistar rats in a concentration-dependent manner. YM598 (0.1 or 1 mg/kg), enalapril (5 mg/kg), an angiotensin- converting enzyme inhibitor, or vehicle was administered once daily by gastric gavage to 22-week-old male OLETF rats for 32 weeks. YM598 blunted the development of albuminuria in a dose-dependent manner. A higher dose of YM598 reduced albuminuria comparable with enalapril. Urinary endothelin-1 excretion was greater in the diabetic rats than in the control rats, and was not substantially influenced by the agents. Enalapril, but not YM598, mildly lowered the blood pressure in the diabetic rats, indicating that blood pressure reduction is not involved in the major mechanism of the renoprotective effect of YM598 in OLETF rats. These data suggest that endothelin is involved in the progression of diabetic nephropathy in OLETF rats, and an endothelin type A antagonist is promising for the treatment of diabetic nephropathy.
