  9-Benzyl-6-(dimethylamino)-9H-purines with antirhinovirus activity

  摘要：

  A series of 9-benzyl-6-(dimethylamino)-9H-purines and 9-benzyl-2-chloro-6-(dimethylamino)-9H-purines were synthesized and tested in cell culture for activity against rhinovirus type 1B. The 9-benzylpurines that were unsubstituted in the 2-position had weak activity. However, introduction of a 2-chloro substituent resulted in a substantial increase in antiviral activity. One of the most active compounds, 2-chloro-6-(dimethylamino)-9-(4-methylbenzyl)-9H-purine (29), had an IC50 value of 0.08 microM against serotype 1B. Four compounds were tested against 18 other rhinovirus serotypes, but the majority tested were less sensitive than type 1B. The range of serotype sensitivity for 29 varied from 0.08 to 14 microM. These 9-benzyl-2-chloro-9H-purines represent a new class of antiviral agents with in vitro activity against rhinoviruses.

  3d and 3h, elicit high affinities to the H3R (Ki values of 2.91 and 5.51 nM, respectively). Both compounds are more potent than the reference drug pitolisant (Ki 6.09 nM) and show low toxicity with in vitro models (IC50 > 30 µM on HEK-293, SH-SY5Y and HepG2 cell lines). Subsequently, binding modes of these ligands are obtained using a model of H3R by docking and molecular dynamics studies, thus determining

  继续我们的计划以获得新的组胺 H 3受体 (H 3 R) 配体，在这项工作中，我们介绍了一系列八种新的可合成嘌呤衍生物的合成、H 3 R 亲和力和计算机模拟研究。这些化合物是根据我们之前的配体吡咯并 [2,3- d ] 嘧啶环中呈现的支架被嘌呤核心等排替代而设计的。该设计还考虑在 C-4 处保留双哌啶片段，在 N-9 处保留带有吸电子基团的芳香环，因为这些片段是拟议药效团的一部分。体外筛选结果表明，两种嘌呤衍生物3d和3h对 H 具有高亲和力3 R（Ki 值分别为 2.91 和 5.51 nM）。这两种化合物都比参考药物 pitolisant (K i 6.09 nM) 更有效，并且在体外模型中表现出低毒性（在 HEK-293、SH-SY5Y 和 HepG2 细胞系上， IC 50 > 30 µM）。随后，使用 H 3 R 模型通过对接和分子动力学研究获得这些配体的结合模式，从而确定嘌呤环在增强亲和力方面的重要性，因为

  9-Benzylpurines have been lithiated in the 8-position and subsequently brominated when trapped with BrCCl2CCl2Br. The 8-bromopurines were isolated in excellent yields when the benzyl group carried an alkoxy or alkyl group in the ortho or para position. Without these substituents, the conversion was generally less, and formation of 8,8'-purinyl dimers was observed. There was also evidence of debenzylation in some instances. Bromination of 7-benzylpurines employing the same set of reaction conditions has also been achieved.
