We determined the experimental solubility of CNS marketed drugs. Of the 98 drugs measured, greater than 90% had solubility >10 μM in pH 7.4 buffer. Only seven drugs had solubility <10 μM. Using these data, we established a solubility criterion to support CNS discovery. The implication of poor solubility with potential safety concerns and undesirable side effects are discussed.
我们测定了中枢神经系统(CNS)上市药物的实验溶解度。在所测量的 98 种药物中,大于 90%的药物在 pH 7.4 缓冲液中的溶解度大于 10 μM。只有 7 种药物的溶解度小于 10 μM。利用这些数据,我们建立了一个溶解度标准来支持 CNS 药物的发现。讨论了溶解度差与潜在安全问题和不良副作用的关系。
