  Synthesis and structure–activity relationships of a series of pyrrole cannabinoid receptor agonists

  摘要：

  We designed and synthesized a series of pyrrole derivatives with the aim of investigating the structure-activity relationship (SAR) for the binding of non-classical agonists to CB1 and CB2 cannabinoid receptors. Superposition of two pyrrole-containing cannabinoid agonists, JWH-007 and JWH-161, allowed us to identify positions 1, 3 and 4 of the pyrrole nucleus as amenable to additional investigation. We prepared the 1-alkyl-2,5-dimethyl-3,4-substituted pyrroles 10a-e, 11a-d, 17, 21, 25 and the tetrahydroindole 15, and evaluated their ability to bind to and activate cannabinoid receptors. Noteworthy in this set of compounds are the 4-bromopyrrole 11a, which has an affinity for CB1 and CB2 receptors comparable to that of well-characterized heterocyclic cannabimimetics such as Win-55,212-2; the amide 25, which, although possessing a moderate affinity for cannabinoid receptors, demonstrates that the 3-naphthoyl group, commonly present in indole and pyrrole cannabimimetics, can be substituted by alternative moieties; and compounds 10d, 11d, showing CB1 partial agonist properties.

  吡咯-3-甲酰胺衍生物作为EZH2（zeste同源物2的增强剂）抑制剂和抗癌剂的设计，合成和生物学活性

  摘要：

  Zeste增强子同源物2（EZH2）在各种恶性肿瘤中高表达，可以通过H3K27的三甲基化沉默沉默抑癌基因。本文首先报道了一系列带有吡啶酮片段作为EZH2抑制剂的吡咯-3-羧酰胺衍生物。通过将计算模型，体外细胞分析以及进一步的合理的构效关系探索和优化相结合，化合物DM-01对EZH2具有强大的抑制作用。在蛋白质印迹试验中，发现DM-01具有降低K562细胞中细胞H3K27me3水平的显着能力。同时，我们的数据显示，敲低A549细胞中的EZH2导致细胞对DM-01的敏感性降低在50和100μM下 DM-01还可以以剂量依赖的方式增加DIRAS3的转录表达，这是EZH2下游的一种抑癌剂，表明它有必要进一步研究作为先导化合物。

  The present invention provides a method for treating NSCL, pancreatic, colon or breast cancer tumors or tumor metastases in a patient, comprising administering to the patient simultaneously or sequentially a therapeutically effective amount of a combination of an EGFR kinase inhibitor and an agent that sensitizes tumor cells to the effects of EGFR kinase inhibitors, wherein the agent is an mTOR inhibitor, with or without additional agents or treatments, such as other anti-cancer drugs or radiation therapy. The present invention also provides a method for treating tumors or tumor metastases in a patient, comprising administering to said patient simultaneously or sequentially a therapeutically effective amount of a combination of an EGFR kinase inhibitor and an agent that sensitizes tumor cells to the effects of EGFR kinase inhibitors, wherein said agent is an mTOR inhibitor that binds to and directly inhibits both mTORC1 and mTORC2 kinases. The present invention also provides a pharmaceutical composition comprising an EGFR kinase inhibitor and an mTOR inhibitor that binds to and directly inhibits both mTORC1 and mTORC2 kinases, in a pharmaceutically acceptable carrier. A preferred example of an EGFR kinase inhibitor that can be used in practicing the methods of this invention is the compound erlotinib HCl (also known as TARCEVA®).
