KR-67607, also known as NTX-101 is novel selective 11β-hydroxysteroid dehydrogenase 1 (11β-HSD1) inhibitor. KR-67607 decreased 4-hydroxynonenal expression and increased antioxidant and mucus secretion in BAC-treated rat eyes. KR-67607 showed its protective effects against ischemia-reperfusion-induced eye injury. KR-67607 effectively reduced cortisol levels in mouse eyes and maintained the trabecular meshwork (TM) structure in the presence of transient ischemic stress. Furthermore, KR-67607 reversed the elevation of intra-ocular pressure (IOP), suggesting that the TM structure maintained by KR-67607 prevented the excessive rise in IOP that exacerbates glaucoma.
