Selective inhibitors of human peptide deformylase (HsPDF) are predicted to constitute a new class of antitumor agents. We report the identification of benzofuran-4,5-diones as the first known selective HsPDF inhibitors and we describe their selectivity profile in a panel of metalloproteases. We characterize their structure–activity relationships for antitumor activity in a panel of cancer cell lines
预计人类肽去甲酰酶 (HsPDF) 的选择性抑制剂将构成一类新的抗肿瘤药物。我们报告了苯并呋喃-4,5-二酮作为第一个已知的选择性 HsPDF 抑制剂的鉴定,我们在一组金属蛋白酶中描述了它们的选择性特征。我们表征了它们在一组癌细胞系中抗肿瘤活性的构效关系,并评估了它们在小鼠异种移植模型中的体内功效。我们的结果表明,基于苯并呋喃-4,5-二酮支架的选择性 HsPDF 抑制剂构成了一类在体外和体内均有效的新型抗肿瘤剂。
