An NMR fragment screen for binders to the bromodomains of BRD4 identified 2-methyl-3-ketopyrroles 1 and 2. Elaboration of these fragments guided by structure-based design provided lead molecules with significant activity in a mouse tumor model. Further modifications to the methylpyrrole core provided compounds with improved properties and enhanced activity in a mouse model of multiple myeloma.
对BRD4溴结构域结合剂的NMR片段筛选确定了2-甲基-3-酮吡咯1和2。通过基于结构的设计指导对这些片段进行加工,可在小鼠肿瘤模型中提供具有重要活性的先导分子。在多发性骨髓瘤的小鼠模型中,对甲基吡咯核的进一步修饰为化合物提供了改善的特性和增强的活性。
