Abstract
Etonogestrel在制备抗B细胞淋巴瘤产品中的应用。
Description
本发明涉及生物技术领域,尤其涉及一种Etonogestrel在制备抗B细胞淋巴瘤产品中的应用。
肿瘤是威胁人类健康的最常见也是最严重的一种疾病,研发高效抗肿瘤药物对延长患者的生存周期至关重要。近年来,随着肿瘤基因组学学和分子药理学的飞速发展,新型抗肿瘤药物的研发取得了不错的成果,但由于新药研发投入大,周期长等瓶颈无法克服,以及肿瘤个体遗传变异大等特征,导致许多传统抗肿瘤药物效果不加,新药价格昂贵,副作用未明。
Etonogestrel是一种主要用于避孕的皮下植入剂,属于甾体孕激素。该药物的避孕机制主要通过对垂体-性腺轴的排卵抑制作用来实现,同时还可以增加子宫颈粘液的粘稠程度,防止精子的进入。目前也有人在背侧海马注射Etonogestrel来对痴呆大鼠学习记忆影响机制进行药物重定位研究。
