13-d in a panel of cancer cell lines showed a selective inhibition of proliferation of a subset of AML lines. Pharmacokinetic studies established that 13-d had properties compatible with oral dosing in mouse models of disease (Fpo 49%). We propose that NI-42 (13-d) is a new chemical probe for the BRPFs suitable for cellular and in vivo studies to explore the fundamental biology of these proteins.
BRPF(含溴结构域和PHD的手指)家族是支架蛋白,对于将MYST家族的组蛋白乙酰基转移酶募集到染色质中很重要。尽管对急性髓细胞性白血病(AML)的作用有了新的认识,但对BRPF家族作为潜在药物靶标的评价仍处于早期阶段。我们报告优化片段命中5b到13-d作为有偏见的,有效的BRPF的BRD抑制剂具有优于非IV BRD蛋白的选择性的最佳选择。在一组癌细胞系中对13-d的评估显示选择性抑制了AML系的一个子集的增殖。药代动力学研究确定13 d具有与疾病小鼠模型中的口服剂量兼容的特性(F Po 49%)。我们建议NI-42(13-d)是BRPF的新化学探针,适用于细胞和体内研究,以探索这些蛋白质的基本生物学特性。
