Idiopathic pulmonary fibrosis (IPF) is a serious and deadly disease for which treatment options are limited. The recent approval of antifibrosis agent nintedanib represents one of the first therapeutic approaches for the treatment of IPF. Here, we report novel indolinone-based multikinase inhibitors that target angiogenesis and fibrosis pathways and may serve as potential therapeutics for IPF. KBP-7018
特发性肺纤维化(IPF)是一种严重且致命的疾病,治疗选择有限。抗纤维化剂nintedanib的最新批准代表了治疗IPF的首批治疗方法之一。在这里,我们报告了新型的基于吲哚啉酮的多激酶抑制剂,这些抑制剂靶向血管生成和纤维化途径,并可能作为IPF的潜在疗法。KBP-7018是一种新型的酪氨酸激酶选择性抑制剂,对三种纤维化激酶(c-KIT,PDGFR和RET)具有有效作用。KBP-7018的药代动力学(PK)特性在小鼠,大鼠和狗中均有利。在博来霉素(BLM)诱导的小鼠肺纤维化模型中,每天10、30和100 mg / kg剂量(qd)的KBP-7018以剂量依赖性方式改善28天生存率。与nintedanib相比,KBP-7018的功效提高,为PDGFR,c-KIT和RET参与IPF提供了一定水平的化学验证。因此,KBP-7018代表了一种新型的多激酶抑制剂,具有差异化的活性,高度增强的选择性和可接受的PK谱,将进入I期临床试验。
