恶性肿瘤是一种严重威胁人类生命健康的重大疾病。目前的治疗手段主要有手术治疗、化学治疗、靶向治疗等。化学治疗是利用化学药物杀死肿瘤细胞、抑制肿瘤细胞生长的一种治疗方式，是一种全身性治疗手段。由于恶性肿瘤的异质性，化学疗法仍然是治疗肿瘤的重要方法。然而正是这种全身性治疗，导致化学疗法具有很大的副作用。开发具有靶向作用的化疗药物存在巨大的未满足的临床需求。
醛酮还原酶(AKR1C3)是醛酮还原酶家族成员，主要参与激素合成和毒素的清除。AKR1C3可被吸烟、酒精、乙型肝炎或丙型肝炎感染等因素诱发过度表达。AKR1C3在多种难治性癌症中过度表达，如肝癌、肺癌、胃癌、食道癌、结直肠癌、前列腺癌，急性淋巴性白血病，尤其是肝癌，其高表比例在60％以上。
目前在临床上有开发AKR1C3抑制剂药物，但没有取得很好的进展。浩鼎公司报道了一种靶向AKR1C3酶化合物OBI-3424。OBI-3424是一个选择性前药，在高表达AKR1C3酶的肿瘤细胞中释放出强效DNA烷基化剂，选择性杀伤高表达AKR1C3的肿瘤细胞，使化学药物具有明显的靶向作用。
目前这个靶点的研究还处在早期阶段，只有OBI-3424进入临床1/2期，适应症主要是肝细胞癌(HCC)、去势性前列腺癌(CRPC)、胰腺癌和T细胞急性淋巴细胞白血病(T-ALL)等，其有效性和安全性还在验证中。所以这一领域还需要更多的探索和研究。

实验例3：式(I)化合物对人肝癌Hep G2原位异种移植瘤模型的体内药效学研究
实验目的：
本试验使用HepG2原位异种移植肿瘤裸小鼠模型评价化合物的抗肿瘤作用。
实验材料：
雌性Balb/C裸小鼠，周龄为6-8周龄，体重为18～22克，胎牛血清(PBS)，培养基EMEM(货号30-2003)，磷酸盐缓冲液，双抗(货号15240-062)，Matrigel基质胶，胰酶。
实验方法与步骤
1.细胞培养准备：HepG2-luc细胞体外单层培养，培养条件为EMEM培养基中加10％热灭活胎牛血清，于37℃含5％CO2培养箱中培养。一周两次用胰酶-EDTA进行消化处理传代。当细胞饱和度为80％-90％时，细胞用胰酶-EDTA消化，计数，重悬于PBS和基质胶中(PBS：基质胶＝1:1)，密度为166.67×106个细胞/mL。
2.肿瘤细胞接种分组：经肌肉注射60mg/kg舒泰50+1.5mg/kg甲苯噻嗪将动物麻醉，待动物至深麻时，将动物进行适当固定，用75％酒精棉球清洁腹部皮肤，用手术剪开约10mm的创口，将0.03mL(PBS：Matrigel＝1:1)的HepG2-luc细胞原位接种于每只小鼠的肝左大叶上，然后将肌肉层创口用可吸收肠线缝合，皮肤创伤口用缝合器缝合。将手术完成的动物放置在保温毯上保温至苏醒。为减少动物的疼痛，将在术后连续3天给予2mg/kg的美洛昔康(皮下注射给药，每天一次)。随机择取15只动物检测信号生长情况，当信号开始上升时，根据生物荧光信号值随机分组，开始给药治疗，详细治疗方案见表7。
表7实验动物分组及给药方案

3.实验指标
实验指标是肿瘤生长能否被延迟或肿瘤能否被治愈。肿瘤接种后每周检测1次动物的生物发光信号和动物体重，持续至观察期结束。生物发光信号数值可被用来计算T/C(其中T为给药组，C为空白对照组在设定时间的生物发光平均强度值)。肿瘤抑制率TGI计算公式：TGI(％)＝[1-(Ti-T0)/(Vi-V0)]×100，其中Ti为治疗组在设定时间的生物发光平均强度；T0为给药起始点的生物发光平均强度。Vi为空白对照组在设定时间的生物发光平均强度；V0为给药起始点生物发光平均强度。
4.化合物对HepG2肝癌裸鼠皮下移植肿瘤生长的抑制作用
本实验评价了式(I)化合物在HepG2肝癌原位异种移植瘤模型中的药效。给药21天时，式(I)化合物在1mg/kg给药剂量下具有显著的抑制肿瘤生长作用，于溶媒对照组相比均为p<0.05。增加式(I)化合物的给药剂量至3mg/kg，抑瘤效果增强。
