摘要:

目的: 研究新型微管蛋白抑制剂YMR-65在Caco-2单层细胞模型中摄取、转运机制,为新药研发提供思路与方法。方法: 建立Caco-2细胞模型,以Caco-2细胞内摄取量考察时间、浓度及温度对化合物YMR-65在Caco-2细胞中摄取的影响,以表观渗透系数(Papp)评价时间、浓度及P-糖蛋白(P-gp)抑制剂维拉帕米对转运的影响。结果: 在摄取模型中,化合物YMR-65在Caco-2细胞中以时间、浓度依赖性方式进行摄取且在测定浓度范围内无明显饱和,温度对化合物摄取无统计学差异;在转运模型中,化合物YMR-65在Caco-2细胞中转运呈现时间、浓度依赖性,且时间、浓度及P-gp抑制剂对化合物在Caco-2细胞中的顶侧及基底侧Papp无统计学差异。结论: 被动扩散是化合物YMR-65在Caco-2细胞模型中的主要摄取转运方式,化合物YMR-65可能不是P-gp的底物。

Abstract:

AIM: To study the uptake and transport characteristics of a novel tubulin inhibitor, YMR-65, in Caco-2 cells model and to provide ideas and methods for new drug development. METHODS: By establishing Caco-2 cell model, the effects of time, concentration and temperature on the uptake of YMR-65 were studied using intracellular uptake amount. Time, concentration or verapamil on its transport in Caco-2 cells were evaluated using apparent permeability coefficient (Papp). RESULTS:In Caco-2 uptake model, the cumulative amount of YMR-65 in Caco-2 cells increased in time- and concentration- manners without obvious saturation and it seemed that the uptake characteristics was unaffected by temperature. Time, concentrations or P-gp inhibitor showed no significant difference to the apparent permeability coefficient (Papp) in Caco-2 cells. CONCLUSION: YMR-65 is passively diffused into Caco-2 cells and it suggests that P-gp might not be involved in the intracellular transport of YMR-65 and it might not be the substrate of P-gp.

Key words: novel tubulin inhibitor, YMR-65, Caco-2 cells
