  Structure–activity relationship study of beta-carboline derivatives as haspin kinase inhibitors

  摘要：

  Haspin is a serine/threonine kinase that phosphorylates Thr-3 of histone H3 in mitosis that has emerged as a possible cancer therapeutic target. High throughput screening of approximately 140,000 compounds identified the beta-carbolines harmine and harmol as moderately potent haspin kinase inhibitors. Based on information obtained from a structure-activity relationship study previously conducted for an acridine series of haspin inhibitors in conjunction with in silico docking using a recently disclosed crystal structure of the kinase, harmine analogs were designed that resulted in significantly increased haspin kinase inhibitory potency. The harmine derivatives also demonstrated less activity towards DYRK2 compared to the acridine series. In vitro mouse liver microsome stability and kinase profiling of a representative member of the harmine series (42, LDN-211898) are also presented. (C) 2012 Elsevier Ltd. All rights reserved.

  四氢-β-咔啉和β-咔啉的微波辅助合成

  摘要：

  开发了一种利用 1,2-二氯乙烷 (DCE) 和三氟乙酸 (TFA) 的微波介导的 Pictet-Spengler 程序，以提供高产率的四氢-β-咔啉盐。反应在 20 分钟或更短的时间内完成，产物以高产率和纯度从溶液中沉淀，无需液-液萃取或柱色谱。这种方法具有广泛的功能，并且可以在毫克到克的范围内进行。随后还利用催化 Pd/C 开发了合成的四氢-β-咔啉到 β-咔啉的后续微波介导的芳构化。芳香化在 60 分钟或更短的时间内完成，大多数底​​物需要最少的纯化。

  chromatography. This method tolerates a wide range of functionality and can be performed on milligram to gram scales. A subsequent microwave-mediated aromatization of the synthesized tetrahydro-β-carbolines to β-carbolines was also developed utilizing catalytic Pd/C. The aromatization is complete in 60 min or less with most substrates requiring minimal purification.
