生物活性
Methotrexate α-tert-butyl ester,经 OtBu 修饰,显著降低 HT1080 荷瘤小鼠的肿瘤生长。Methotrexate 是一种抗代谢和抗叶叶酸剂,也是一种免疫抑制剂和抗肿瘤药物。体外研究
OtBu-MTX-PVG is less HT1080 than MTX-PVG against HT1080 cells. It shows that protection of the α-carboxyl group of MTX results in reduced in vitro activity.
体内研究
Lys-MTXcleavable- (OtBu) significantly reduces tumor growth in HT1080 tumor bearing mice.
The protection of the α-carboxyl group of methotrexate may be used to improve the circulatory half-life and reduce the liver accumulation of similar MTX-conjugated dendrimers, while still retaining antitumor activity in vivo.
