摘要
背景:在过去的几年里,对首次鉴定的histone demethylase LSD1的鉴定和鉴定有了很大的关注,它可以抹去单 - 和二 - 甲基化组蛋白3赖氨酸4和9。由于LSD1的异常过表达参与了各种病理过程,尤其是癌症,获得选择性和有效的LSD1抑制剂已成为药物化学研究中的一个关键问题。 方法:目前已经建立了几种LSD1抑制剂筛选模型,包括酶偶联试验、基于lc - ms的分析和基于焦虑的分析。然而,由于某些特殊仪器的要求以及lc - ms和烦恼的额外费用,酶耦合试验是LSD1抑制剂筛选最广泛应用的方法。 结果:我们总结并比较了几种体外LSD1抑制剂筛选模型。每一种方法都有各自的优点和缺点,这些方法都不完美。为了排除错误的阳性结果,至少应该应用一个额外的方法来筛选LSD1抑制剂。

摘要: Background: In the past few years, great of attention has been paid to the identification and characterization of selective and potent inhibitors of the first identified histone demethylase LSD1, which may erase mono- and di-methylated histone 3 lysine 4 and 9. As the aberrant overexpression of LSD1 is involved in various pathological processes, especially cancer, obtaining selective and potent LSD1 inhibitors has emerged as a crucial issue in medicinal chemistry research.
Method: Until now, several LSD1 inhibitor screening models have been established, including enzyme coupled assay, LC-MS based assay, and FRET based assay. Nevertheless, due to some special instrument requirement and additional costs of LC-MS and FRET, the enzyme coupled assay is the most widely applied method for LSD1 inhibitor screening. Result: We summarized and compared several reported in vitro LSD1 inhibitor screening models. Each of them has distinct advantages and disadvantages, and none of these methods is perfect. In order to exclude the false positive results, at least one additional method should be applied to screen LSD1 inhibitors.Export Options
