Abstract

β-Lap prodrug micelle strategy improves the formulation properties of β-lap therapeutics. The resulting micelles yield apparent high β-lap solubility (>7 mg mL(-1) ), physical stability, and ability to reconstitute after lyophilization. In the presence of esterase, β-lap prodrugs are efficiently converted into parent drug (i.e., β-lap), resulting in NQO1-dependent lethality of NSCLC cells.

摘要

β-拉帕替尼前药胶束策略改善了β-拉帕替尼治疗药物的制剂性质。所得胶束具有明显的高β-拉帕替尼溶解度(>7毫克/毫升)、物理稳定性以及冻干后复溶的能力。在酯酶存在的情况下,β-拉帕替尼前药可有效转化为母体药物(即β-拉帕替尼),从而导致非小细胞肺癌细胞发生NQO1依赖性致死。
