  1,2,4-Triazolo[4,3-a]pyrazine derivatives with human renin inhibitory activity. 1. Synthesis and biological properties of alkyl alcohol and statine derivatives

  摘要：

  A series of 1,2,4-triazolo[4,3-a]pyrazine derivatives with human renin inhibitory activity, which incorporate (1S,2S)-2-amino-1,3-dicyclohexyl-1-hydroxypropane, statine (Sta), and (3S,4S)-4-amino-5-cyclohexyl-3-hydroxy-pentanoic acid (ACHPA) transition-state mimetics, have been prepared. Structure-activity relationships for renin inhibitory activity in the series are consistent with the 2-[8-isobutyl-6-phenyl-1,2,4-triazolo[4,3-a]pyrazin-3-yl]-3-(3 pyridyl)propionic acid moiety 10b acting as a non-peptidic replacement for the P4-P2 (Pro-Phe-His) residues of the natural substrate angiotensinogen. Compounds 12m, 12o and 12q were potent inhibitors of partially purified human renin (IC50 values 1.7, 6.8, and 3.7 nM, respectively), and also effectively lowered blood pressure in anesthetized, sodium depleted marmosets following intravenous administration. On oral administration however, no blood pressure lowering activity could be detected, and absorption studies in bile duct cannulated rats indicate that this may be due primarily to poor oral absorption, rather than rapid biliary excretion. The reason for the observed poor oral activity is not clear, but it seems unlikely that poor aqueous solubility or metabolic instability to gut enzymes are rate-determining, and other factors such as high molecular weight may also be very important.

  The synthesis of a variety of potent macrocyclic growth hormone secretagogues, i.e.5, 9, 12, and 20–22, based on the known lead structure L-692,429 (1) is described. These conformationally constrained growth hormone secretagogues were prepared by joining the two essential pharmacophores, the amino-acid side chain at the 1H-1-benzazepine moiety and the 1,1′-biphenyl moiety with a variety of linkers

  The carbapenem class of β‐lactams has been optimized against Gram‐negative bacteria producing extended‐spectrum β‐lactamases by introducing substituents at position C2. Carbapenems are currently investigated for the treatment of tuberculosis as these drugs are potent covalent inhibitors of l,d‐transpeptidases involved in mycobacterial cell wall assembly. The optimization of carbapenems for inactivation

  碳青霉烯类β-内酰胺类通过针对C2位置引入取代基而针对产生广谱β-内酰胺酶的革兰氏阴性细菌进行了优化。目前正在研究碳青霉烯类药物用于治疗结核病，因为这些药物是l，d的有效共价抑制剂参与分枝杆菌细胞壁组装的转肽酶。本文通过利用C 8羟基的亲核性引入化学多样性来寻找用于灭活这些异常靶标的碳青霉烯类的优化。由于β-内酰胺是肽聚糖前体的结构类似物，因此选择取代基可增加药物和底物之间的相似性。有效地合成了十四个肽-卡宾。由于在位置C2引入苯乙硫基取代基的积极影响，它们比美罗培南参考药物更有效，但在位置C8添加的拟肽不能进一步提高活性。因此，可以修饰位置C8以调节高效碳青霉烯类的药代动力学性质。
