  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.

• Enzymatic Formation of a Skipped Methyl‐Substituted Octaprenyl Side Chain of Longestin (KS‐505a): Involvement of Homo‐IPP as a Common Extender Unit

  Longestin (KS‐505a), a specific inhibitor of phosphodiesterase, is a meroterpenoid that consists of a unique octacyclic terpene skeleton with branched methyl groups at unusual positions (C1 and C12). Biochemical analysis of Lon23, a methyltransferase involved in the biosynthesis of longestin, demonstrated that it methylates homoisopentenyl diphosphate (homo‐IPP) to afford (3Z)‐3‐methyl IPP. This compound

  Longestin（KS‐505a）是磷酸二酯酶的特异性抑制剂，是一种类萜，由独特的八环萜烯骨架组成，在异常位置（C1和C12）带有分支甲基。Lon23（一种参与Longestin生物合成的甲基转移酶）的生化分析表明，它可以将均异戊烯基二磷酸（homo-IPP）甲基化以提供（3 Z）-3-甲基IPP。该化合物与IPP一起被Lon22（香叶基香叶基香叶基二磷酸（GGPP）合酶同系物）选择性地接受为扩展单元，从而生成二甲基化GGPP（dmGGPP）。dmGGPP的绝对配置确定为（4 R，12 R）降解和手性GC分析。这些发现使我们能够为不寻常的同萜类长汀的生物合成途径的关键步骤提出酶促序列。

  日期：2007.5

  A convenient synthesis method of antisepsis agent TAK-242 ((R)-1) through diastereomeric resolution was developed. By condensation of racemate rac-1 with chiral acid (S)-O-acetylmanderic acid (6a), the desired diastereomer 5a was isolated with 98% de in 39% yield by simple crystallization. Deacylation of 5a with aq NaOH followed by recrystallization provided (R)-1 with 99% ee in 20% yield from rac-1
