Structural Optimization and Biological Evaluation of 2-Substituted 5-Hydroxyindole-3-carboxylates as Potent Inhibitors of Human 5-Lipoxygenase
摘要:
Pharmacological suppression of leukotriene biosynthesis by inhibitors of 5-lipoxygenase (5-LO) is a strategy to intervene with inflammatory and allergic disorders. We recently presented 2-amino-5-hydroxy-1H-indoles as efficient 5-LO inhibitors in cell-based and cell-free assays. Structural optimization led to novel benzo[g]indole-3-carboxylates exemplified by ethyl 2-(3-chlorobenzyl)-5-hydroxy-1H-benzo[g]indole-3-carboxylate (compound 11a), which inhibits 5-LO activity in human neutrophils and recombinant human 5-LO with IC50 values of 0.23 and 0.086 mu M, respectively. Notably, 11a efficiently blocks 5-LO product formation in human whole blood assays (IC50 = 0.83-1.6 mu M) and significantly prevented leukotriene B-4 production in pleural exudates of carrageenan-treated rats, associated with reduced severity of pleurisy. Together, on the basis of their high potency against 5-LO and the marked efficacy in biological systems, these novel and straightforward benzo[g]indole-3-carboxylates may have potential as anti-inflammatory therapeutics.
由于 Axl 与肿瘤生长、转移、较差的存活率和耐药性具有很强的相关性,因此 Axl 已成为癌症治疗的一个有吸引力的靶点。在此,我们报告了一系列吡咯并[2,3- d ]嘧啶衍生物作为新型 Axl 抑制剂的设计、合成和构效关系 (SAR) 研究。其中,最有前途的化合物13b显示出高酶促和细胞 Axl 效力。此外,13b具有较好的药代动力学特性,并在 BaF3/TEL-Axl 异种移植肿瘤模型中显示出良好的治疗效果。化合物13b可作为新抗肿瘤药物发现的先导化合物。
