体外研究 | 培美曲塞(LY231514)二钠是一种新型经典抗叶酸剂,其抗肿瘤活性可能是由于其多聚谷氨酸化代谢物同时和多重抑制几种关键的叶酸需要酶。培美曲塞(LY231514)是已知用于FPGS的最佳底物之一(Km =1.6μM和Vmax/Km = 621)。多糖化和LY231514的多谷氨酸化代谢物可能在确定该新药的选择性和抗肿瘤活性方面发挥重要作用。尽管LY23154仅适度抑制TS(Ki = 340nM,重组小鼠),但LY23154的戊谷氨酸的效力是100倍(Ki = 3.4nM),使得LY231514成为最有效的基于叶酸的TS抑制剂之一[1]。 |
体内研究 | 用PC61加培美曲塞治疗的小鼠组在统计学上显示出比其他组更长的存活期。在生存分析中,与单用PC61,大鼠IgG加培美曲塞治疗或未治疗的患者相比,用PC61加培美曲塞治疗的小鼠组观察到明显更好的生存[2]。 |
激酶实验 | 通过在A298监测由10-甲酰基 - [6R,S] -5,6,7,8-四氢叶酸的[6S] -5,6,7,8-四氢叶酸的形成,在室温下进行AICARFT抑制试验。所有溶液在使用前用N 2气体吹扫。反应溶液含有33mM Tris-Cl,pH 7.4,25mM KCl,5mM 2-巯基乙醇,0.05mM AICA核糖核苷酸和16nM(2毫单位/ mL)AICARFT。使用10-甲酰基 - [6R,S] -5,6,7,8-四氢叶酸盐浓度0.037,0.074和0.145mM(分别为其Km值的0.61,1.23和2.45倍)。测试LY231514作为0.08-0.8mM(四种浓度)的抑制剂。当LY231514的三 - 和五谷氨酸盐用作抑制剂时,浓度为0.0005-0.009mM(八种浓度)。通过添加酶引发酶测定。使用ENZFITTER程序分析数据以进行竞争性抑制。 |
细胞实验 | 产生剂量 - 反应曲线以确定50%生长抑制所需的浓度(IC 50)。培美曲塞最初以4mg / mL的浓度溶解于DMSO中,并进一步用细胞培养基稀释至所需浓度。将完全培养基中的CCRF-CEM白血病细胞加入到24孔Cluster平板中,终浓度为4.8×10 4细胞/孔,总体积为2mL。将各种浓度的测试化合物加入到两个孔中,使得DMSO的最终体积为0.5%。将板在37℃,5%CO 2的空气气氛中温育72小时。在孵育结束时,在ZBI Coulter计数器上测定细胞数。对照孔通常在孵育结束时含有4×105至6×10 5个细胞。对于一些研究,在300μMAICA,5μM胸苷,100μM次黄嘌呤或5μM嘧啶加100μM次黄嘌呤的组合存在下测定每种化合物的IC50 [1]。 |
动物实验 | 小鼠[2]使用6-8周龄的雌性CBA小鼠和雌性NOD / SCID小鼠(NOD.CB17-Prkdcscid)。从第4-8天(连续5天)腹膜内给予预甲状腺素(100mg / kg)至荷瘤小鼠,以探索当与抗CD25Ab或IgG对照组合时的协同效应。在当前研究中用于培美曲塞的剂量和时间表是基于先前在小鼠中的研究确定的。 |
