  Structure-activity relationships in prazosin-related compounds. Effect of replacing a piperazine ring with an alkanediamine moiety on .alpha.1-adrenoreceptor blocking activity

  摘要：

  Several prazosin-related compounds were synthesized in which the piperazine ring of prazosin (1) was replaced by an alkanediamine chain and were evaluated for their blocking activity on alpha 1- and alpha 2-adrenoreceptors in isolated rat vas deferens. All the compounds investigated proved highly selective toward the alpha 1-adrenoreceptor owing to a very low affinity for alpha 2-adrenoreceptors. Furthermore, compounds 2, 9, and 13 were also investigated in vivo to determine their hypotensive effect on anesthetized rats, which were compared with that of prazosin (1). It was confirmed that the piperazine moiety of 1 is not essential for potency. However, optimum activity depends on two parameters: carbon-chain length of the alkanediamine moiety and N-methylation of both the amide and the 2-amino functions. In the desmethyl series, optimum activity was associated with the lower homologues (2-4) bearing a chain of two to four methylenes whereas in the N,N'-dimethyl series peak potency was observed with a six-carbon chain as in 13. Compound 13 proved the most active of the series and was more potent than prazosin (1) in both in vivo and in vitro assays. It is hypothesized that the alpha 1-adrenoreceptor incorporates a lipophilic area that is located between the binding sites for the quinazoline and the furoyl moieties and is able to accommodate a polymethylene chain.

  尿素硫代糖苷的合成，作为新型昆虫β-N-乙酰基己糖胺酶Hex1抑制剂。

  摘要：

  β-昆虫ñ从-acetylhexosaminidase OfHex1亚洲玉米螟（最具破坏性的农业害虫之一）已被认为是有希望的农药目标。在这项研究中，基于OfHex1与底物的催化机理和共晶体结构，设计并合成了一系列新颖且易于获得的脲基硫糖苷。通过酶抑制实验评估后，发现硫糖苷11c和15k具有对OfHex1的抑制活性，其K i值分别为25.6 µM和53.8 µM。此外，所有这些脲基硫代糖苷对hOGA和HsHexB（K i> 100μM）。此外，为了研究其抑制机理，基于分子对接分析推导了11c和15k与OfHex1的可能结合方式。这项工作可能为进一步合理设计OfHex1抑制剂提供有用的结构起点。
