Stearoyl-CoA desaturase-1 (SCD1) catalyzes de novo synthesis of monounsaturated fatty acids from saturated fatty acids. Studies have demonstrated that rodents lacking a functional SCD1 gene have an improved metabolic profile, including reduced weight gain, lower triglycerides, and improved insulin response. In this study, we discovered a series of piperazinylpyridazine-based highly potent, selective, and orally bioavailable compounds. Particularly, compound 49 (XEN103) was highly active in vitro (mSCD1 IC50 = 14 nM and HepG2 IC50 = 12 nM) and efficacious in vivo (ED50 = 0.8 mg/kg). It also demonstrated striking reduction of weight gain in a rodent model. Our findings with small-molecule SCD1 inhibitors confirm the importance of this target in metabolic regulation, describe novel models for assessing SCD1 inhibitors for efficacy and tolerability and demonstrate an opportunity to develop a novel therapy for metabolic disease.
