Dasatinib was identified as a potent orally administered Src/Abl kinase inhibitor with excellent antiproliferative activity against Philadelphia chromosome-positive chronic myelogenous leukemia in chronic phase. The low bioavailability of Dasatinib may be due to both incomplete oral absorption and first-pass metabolism. A prodrug, JLTN, was synthesized to minimize the first-pass effect of Dasatinib and improve the oral bioavailability following oral administration via targeting intestinal peptide transporter and enhancing chemical stability. Biological evaluation data indicated that there was a 150%-fold increase in oral bioavailability of this prodrug compared to the parent drug Dasatinib in monkeys.
达沙替尼被确定为一种有效的口服 Src/Abl 激酶抑制剂,对慢性期费城染色体阳性慢性粒细胞白血病具有优异的抗增殖活性。达沙替尼的生物利用度低可能是由于口服吸收不完全和首过代谢所致。合成了前药 JLTN,以最大限度地减少达沙替尼的首过效应,并通过靶向肠肽转运蛋白和增强化学稳定性来提高口服给药后的口服生物利用度。生物学评价数据表明,该前药在猴子体内的口服生物利用度比母药达沙替尼增加了150%。
