effective therapies. The RGD (Arg‐Gly‐Asp) integrin αvβ1 was recently investigated for its role in fibrotic disease, and thus warrants therapeutic targeting. Herein we describe the identification of non‐RGD hit small‐molecule αvβ1 inhibitors. We show that αvβ1 activity is embedded in a range of published α4β1 (VLA‐4) ligands; we also demonstrate how a non‐RGD integrin inhibitor (of α4β1 in this case) was
在发达国家,多达45%的死亡可归因于慢性纤维增生性疾病,这凸显了对有效疗法的需求。最近研究了RGD(Arg-Gly-Asp)整联蛋白αvβ1在纤维化疾病中的作用,因此值得治疗靶向。在本文中,我们描述了非RGD命中的小分子αvβ1抑制剂的鉴定。我们表明,αvβ1的活性嵌入了一系列已发布的α4β1(VLA-4)配体中。我们还展示了如何将非RGD整联蛋白抑制剂(在这种情况下为α4β1)转化为有效的非两性离子RGD整联蛋白抑制剂(在这种情况下为αvβ1)。我们设计了对α4β1和其他αv整联蛋白(αvβ3,αvβ5,αvβ6,αvβ8)具有优异选择性的脲配体。在计算机对接模型和密度泛函理论(DFT)计算的帮助下,发现了尿素铅系列。
