Background | Galeterone is a selective CYP17 inhibitor and androgen receptor (AR) (androgen receptor) antagonist. |
Biological Activity | TOK-001 是一种多功能的抗雄激素,是 CYP17 抑制剂,在去势抵抗性前列腺癌中,IC50 为 47 nM。[1-3] |
IC50 | 47nM(CYP17)[1] |
In Vitro | TOK-001提供强大的CYP17裂解酶抑制作用,IC50为47 nM [1]。 TOK-001既是CYP17A1抑制剂又是雄激素受体拮抗剂,这些结合模式的相似性可能是这种双重作用机制的原因。这种CYP17A1与阿比特龙和TOK-001结合,吸光度在402 nm处降低,在424 nm处增加,与氮结合血红素铁(II型相互作用)一致,Kd <100 nM [2]。当LNCaP细胞在补充有炭剥离血清(CSS,T <1 nM)的培养基中培养,然后用增加浓度的TOK-001处理后,AR蛋白的稳态水平显著降低(高达84%,15 μMTOK-001)。在LAPC-4细胞中,在浓度大于或等于1μM时,阿比特龙醇比TOK-001更大程度地降低AR表达。当用20μMTOK-001处理LNCaP细胞24小时时,AR mRNA水平降低38%[3]。 |
In Vivo | 用LAPC-4肿瘤接种的小鼠每天两次皮下注射0.15mmol / kg TOK-001。与对照相比,用TOK-001处理的小鼠在第31天具有更小的平均肿瘤体积(p = 0.0001)。与对照相比,TOK-001治疗还显著降低肿瘤生长的生长速率(p <0.0001)。切除后,与用对照和阉割治疗的动物相比,用TOK-001治疗的动物的最终肿瘤重量也显著降低(p <0.05)[1]。 |
Cell Experiment | 在转染前一天,将LNCaP细胞接种在24孔板中,70%汇合。然后用携带pIR-AR 5'UTR-Luc(5'UTR;测试)或pIRES-Luc(IRES,对照)的质粒DNA(0.5μg/孔)在无血清和无抗生素条件下转染细胞6小时。 。两种荧光素酶报告基因的转录都在CMV启动子的控制下。根据制造商的说明,Lipofectamine 2000试剂用于所有转染。然后用5%FBS/T培养基中的TOK-001(0,10和20μM)剂量处理细胞。使用BMG Labtech酶标仪在处理后36小时使用来自Promega的荧光素酶测定系统测量荧光素酶报告基因活性。将相对荧光素酶单位标准化为总蛋白质,然后标准化为载体对照(pIR-AR 5'UTR-Luc),结果表示为荧光素酶活性。对于细胞增殖研究,在药物处理前24小时接种96孔板中的LNCaP细胞,然后用对照(模拟),TOK-001(10μM)或阿比特龙醇(10μM)在5%FBS/T中处理。 - 培养72小时。使用MTS确定细胞增殖[3]。 |
Animal Experiment | 小鼠[1]每天两次用0.15mmol / kg TOK-001皮下处理用LAPC-4肿瘤接种的小鼠。与对照相比,用TOK-001处理的小鼠在第31天具有更小的平均肿瘤体积(p = 0.0001)。与对照相比,TOK-001治疗还显著降低了肿瘤生长的生长速率(p <0.0001)。切除后,与用对照和阉割处理的动物相比,用TOK-001处理的动物的最终肿瘤重量也显著降低(p <0.05)。 |
Kinase Experiment | 使用具有UV检测的改良HPLC方法评估孕酮17α-羟基化。将CYP17A1(50pmol)和大鼠NADPH-细胞色素P450还原酶1:4混合,在冰上孵育(20分钟),并加入含有黄体酮(0-50μM)的缓冲液(50mM Tris,pH7.4和5mM MgCl2)中。总体积为500μL。包括磷脂酰胆碱(25μg)用于与全长酶的并列动力学比较。对于IC50测定,对于阿比特龙,抑制剂浓度为0-1500nM,对于TOK-001,抑制剂浓度为0-3000nM(Shanghai Haoyuan Chemexpress Co.,Shanghai,China)。升温(37℃,3分钟)后,通过添加NADPH(20μL25mM)引发反应,温育10分钟(37℃),并用20%三氯乙酸(300μL)淬灭并置于冰上。在HPLC分离后,通过在248nm的UV检测鉴定17α-羟孕酮代谢物,并用真实标准物共洗脱。 HPLC流动相为40%乙腈,60%水和1%乙酸,以1 mL/min运行(Phenomenex,Luna5μ,C18,50×4.6 mm)[2]。 |
