This invention is based on the discovery that many eye conditions associated with aging are mediated at least in part by cells bearing a senescent phenotype. Senescent cells accumulate with age, and express factors that contribute to the pathophysiology of age related conditions. The data show that in age-matched patients, the severity of age-related conditions correlates with the abundance of senescent cells, and that clearing senescent cells can help abrogate the condition. Small molecule drugs that remove senescent cells from affected tissue in the eye are provided that have special efficacy in treating ophthalmic conditions. They not only inhibit progression of the disease, they can also reverse some of the pathophysiology—such as neovascularization and vaso-obliteration—that lead to vision loss. These senolytic agents have an appropriate dose and specificity profile to be effective in the clinical management of previously intractable ophthalmic conditions.
本发明基于以下发现:许多与衰老相关的眼部疾病至少部分是由具有衰老表型的细胞介导的。衰老细胞随着年龄的增长而积聚,并表达有助于老年相关疾病病理生理学的因子。数据显示,在年龄匹配的患者中,年龄相关疾病的严重程度与衰老细胞的数量相关,清除衰老细胞有助于缓解病情。清除眼部受影响组织中衰老细胞的小分子药物在治疗眼科疾病方面具有特殊疗效。它们不仅能抑制疾病的发展,还能逆转一些导致视力下降的病理生理学现象,如新生血管和血管闭塞。这些衰老溶解剂具有适当的剂量和特异性特征,可以有效地用于以前难以治愈的眼科疾病的临床治疗。
