  Structure−Activity Relationship of Quinoline Derivatives as Potent and Selective α_2C-Adrenoceptor Antagonists

  摘要：

  Starting from two acridine compounds identified in a high-throughput screening campaign (1 and 2, Table 1), a series of 4-aminoquinolines was synthesized and tested for their properties on the human alpha(2)-adrenoceptor subtypes (alpha(2A), alpha(2B), and alpha(2C.)). A number of compounds with good antagonist potencies against the alpha(2C)-adrenoceptor and excellent subtype selectivities over the other two subtypes were discovered. For example, (R)-{4-[4-(3,4-dimethylpiperazin-1-yl) phenylamino] quinolin- 3- yl} methanol 6j had an antagonist potency of 8.5 nM against, and a subtype selectivity of more than 200-fold for, the alpha(2C)-adrenoceptor. Investigation of the structure-activity relationship identified a number of structural features, the most critical of which was an absolute need for a substituent in the 3-position of the quinoline ring. The 3-position on the piperazine ring was also found to play an appreciable role, as substitutions in that position exerted a significant and stereospecific beneficial effect on the alpha(2C)-adrenoceptor affinity and potency. Replacing the piperazine ring proved difficult, with 1,4-diazepanes representing the only viable alternative.

  For an analog‐based design of novel Wee1 inhibitors, we profiled in vitro ADMET and in vivo PK properties of adavosertib. Based on the properties of adavosertib, we aimed to improve its metabolic stability by designing a novel target compound 1a with an aminosulfonyl group instead of the 2‐hydroxypropan‐2‐yl moiety in adavosertib. Derivatives of target compound 1a were synthesized and evaluated for Wee1 enzyme inhibition and liver microsomal phase I stability. We identified compound 1a as a sub‐nanomolar Wee1 inhibitor and 10 additional compounds with one‐digit nanomolar Wee1 inhibitory activity, among which seven compounds including 1a exhibited improved metabolic stabilities compared with adavosertib. However, MDA‐MB‐231 cell growth inhibitory activities of all synthesized compounds and Wee1 substrate phosphorylation inhibitory activities of selected compounds were inferior to adavosertib overall. Moreover, the representative compound 1a exhibited low permeability, which may be the reason for the low cellular activities of compound 1a.

  摘要为了设计基于类似物的新型Wee1抑制剂，我们分析了adavosertib的体外ADMET和体内PK特性。根据阿达沃舍替的特性，我们设计了一种新型靶向化合物 1a，用氨基磺酰基取代阿达沃舍替中的 2-羟基丙-2-基，从而提高其代谢稳定性。我们合成了目标化合物 1a 的衍生物，并对其 Wee1 酶抑制作用和肝微粒体 I 期稳定性进行了评估。我们发现化合物 1a 是亚纳摩尔 Wee1 抑制剂，另有 10 个化合物具有一位数纳摩尔的 Wee1 抑制活性，其中包括 1a 在内的 7 个化合物的代谢稳定性比 adavosertib 有所提高。然而，所有合成化合物的 MDA-MB-231 细胞生长抑制活性和所选化合物的 Wee1 底物磷酸化抑制活性总体上均逊于 adavosertib。此外，代表性化合物 1a 的渗透性较低，这可能是化合物 1a 细胞活性较低的原因。
