inhibitors with an improved safety profile by selective targeting of a subset of the eight bromodomains of the BET family has triggered extensive medicinal chemistry efforts. In this article, we disclose the identification of potent and selective drug-like pan-BD2 inhibitors such as pyrazole 23 (GSK809) and furan 24 (GSK743) that were derived from the pyrrole fragment 6. We transpose the key learnings from
pan-BET 抑制剂的深远功效已得到充分证明,但这些表观遗传药物在肿瘤临床试验中已显示出药理学驱动的毒性。通过选择性靶向 BET 家族的八个溴结构域的一个子集来识别具有改进安全性的抑制剂的机会引发了广泛的药物化学工作。在这篇文章中,我们公开了从吡咯片段6衍生的有效和选择性药物样泛 BD2 抑制剂的鉴定,例如吡唑23 (GSK809) 和呋喃24 (GSK743) 。我们将先前吡啶酮系列 (GSK620 2 作为一个代表性的例子)到这类新型抑制剂,其特点是相对于我们之前的研究显着提高了溶解度。
