a normotensive rabbit model, with a significant difference in activity observed. No toxic effects on cell structure or alterations in morphology of the aqueous humor outflow pathway were observed after treatment with the most efficacious compound, (3S,4R)-2, suggesting that it is a strong candidate for development as an ocular hypotensive agent.
ATP敏感性钾(K ATP)通道开放剂已成为治疗青光眼,降低动物模型和培养的人前眼节的眼内压(IOP)的潜在疗法。我们已经制备了K ATP的水溶性磷酸酯和二肽衍生物开沟剂cromakalim并评估了它们在体内降低IOP的能力。通常,在血压正常的小鼠模型中,每天给药一次,磷酸盐衍生物在降低IOP方面具有更强的化学稳定性和有效性。在正常血压的兔子模型中进一步评估了其中的两种磷酸盐衍生物,观察到活性存在显着差异。用最有效的化合物(3 S,4 R)-2处理后,未观察到对房水流出通道的细胞结构或形态变化有毒害作用,表明它是发展为眼压降压药的强力候选者。 。
