With the aim to address an undesired cardiac issue observed with our related compound in the recently disclosed novel series of renin inhibitors, further chemical modifications of this series were performed. Extensive structure-activity relationships studies as well as in vivo cardiac studies using the electrophysiology rat model led to the discovery of clinical candidate trans-adamantan-1-ol analogue 56 (DS-8108b) as a potent renin inhibitor with reduced potential cardiac risk. Oral administration of single doses of 3 and 10 mg/kg of 56 in cynomolgus monkeys pre-treated with furosemide led to significant reduction of mean arterial blood pressure for more than 12 h.

Novel nonpeptide small molecule renin inhibitors bearing an N-isopropyl P1 motif were designed based on initial lead structures 1 and aliskiren (2). (P3-P1)-Benzamide derivatives such as 9a and 34, as well as the corresponding P1 basic tertiary amine derivatives 10 and 35 were found to display low nanomolar inhibition against human renin in vitro.
