We disclose a compound of formula I: [X]n-[Y]m-Z where X represents a fluorophore group covalently linked to the rest of the molecule by way of an oxygen atom or an NH group; Y is a self-immolative linking group; Z represents an N-blocked dipeptide Gly-Pro; n is 1 -2; and m is 0-1. The fluorophore X does not fluoresce when attached to the rest of the molecule by way of a covalent bond, but is capable of fluorescence following cleavage of said covalent bond. The compounds of formula I are useful as a fluorescent probe in the diagnosis of fibrotic conditions in vivo, such as keloidal and/or hypertrophic scarring, and may also be used in an in vitro test to screen for compounds useful to treat such fibrotic conditions. Also disclosed herein is the use of RepSox and thiazovivin, whether alone or in combination, to treat fibrotic conditions.
我们披露了一种具有
化学式I的化合物:[X]n-[Y]m-Z,其中X代表与分子其余部分通过氧原子或NH基共价连接的荧光团;Y是自灭联结基团;Z代表N-阻断二肽甘
氨酸-脯
氨酸;n为1-2;m为0-1。荧光团X在通过共价键连接到分子其余部分时不发出荧光,但在断开该共价键后能够发出荧光。
化学式I的化合物可用作体内纤维化疾病的诊断荧光探针,例如瘢痕性和/或肥厚性瘢痕,并且还可用于体外试验以筛选用于治疗这些纤维化疾病的化合物。本文还披露了使用RepSox和thiazovivin,无论是单独使用还是结合使用,来治疗纤维化疾病。
