  Derivatives of the potent angiotensin converting enzyme inhibitor 5(S)-benzamido-4-oxo-6-phenylhexanoyl-L-proline: effect of changes at postions 2 and 5 of the hexanoic acid portion

  摘要：

  Several derivatives of the potent angiotensin converting enzyme inhibitor 5(S)-benzamido-4-oxo-6-phenylhexanoyl-L-proline (1) were synthesized and tested for converting enzyme inhibition activity and blood pressure lowering effects in rats. One compound, 5(S)-benzamido-2(R)-methyl-4-oxo-6-phenylhexanoyl-L-proline (2a), had and I50 against angiotensin converting enzyme of 1.0 x 10(-9) M and is the most potent inhibitor prepared thus far in this class of compounds. Testing of 2a orally at 30 mg/kg for inhibition of the angiotensin I induced blood pressure increase in conscious normotensive rats gave 100% inhibition that required 143 min before the angiotensin I blood pressure response returned to 70% of the pretreatment control response. In the conscious renal hypertensive rat, 2a given orally at a dose of 3 mg/kg caused a lowering of blood pressure that reached its maximum of 40 mmHg 8 h following drug administration.

  in vitro angiotensin converting enzyme (ACE) inhibitory activity of 1 was confirmed. Some of the novel analogues (6, 11, 13, and 17) were also found to be potent inhibitors of ACE in vitro with an IC50 of 1.4-8.8 x 10(-9) M (IC50 for captopril = 0.9 x 10(-8) M). In vivo these compounds (6, 11, 17, and 18) were much less active than captopril, especially by the oral route. Against angiotensin I (AI) challenge

Analogue II was a full agonist contracting the isolated guinea pig ileum with a potency of 70% compared to the parent hexapeptide [pGlu6]SP6-11. It was also a potent inhibitor of SP degrading activity in rat diencephalon membranes with a Ki of 20 microM whereas analogue I was a weak inhibitor.

  A new approach to the enantiocontrolled synthesis of α-amino ketone derivatives is disclosed by employing a nickel-catalyzed decarboxylative acylation strategy. Starting from readily available acyl chlorides and α-amino acids-derived redox-active esters, the reaction exhibits broad substrate scope, easy scalability, and is applied to dramatically simplify the synthesis of several known structures.
