背景说明 |
Ro 48-8071 fumarate 是一种氧化鲨烯环化酶抑制剂。 |
生物活性 |
Ro 48-8071 fumarate is an inhibitor of OSC (Oxidosqualene cyclase) with IC50 of appr 6.5 nM.[1-4] |
IC50 |
IC50: appr 6.5 nM (Oxidosqualene cyclase)[1] |
In Vitro |
在 HepG2 细胞中,Ro 48 -8071 降低胆固醇合成剂量依赖性,IC50 值约为 1.5 nM[1]。Ro 48 -8071 (10 μM) 显著降低 PC-3 前列腺癌细胞的活力,但不降低正常前列腺细胞的活力。Ro 48 -8071 (10-30 μM) 以剂量依赖的方式诱导 LNCaP 和 C4-2 细胞系的凋亡。在用 Ro 48 -8071 处理 24 小时后,去势抵抗性 PC-3 和 DU145 细胞也表现出显著水平的细胞凋亡。Ro 48 -8071 (10-25 μM) 以剂量依赖的方式降低 AR 蛋白的表达。Ro 48 -8071 (0.1-1 μM) 在激素依赖性 LNCaP 和去势抵抗性 PC-3 细胞中剂量依赖性地增加 ERβ 蛋白表达[2]。使用经过改造以表达人 ERα 或 ERβ 蛋白的哺乳动物细胞,连同 ER 反应性荧光素酶启动子,Ro 48 -8071 剂量依赖性地抑制 17β-雌二醇 (E2) 诱导的 ERα 反应性荧光素酶活性 (IC50,appr 10 μM),在对细胞无毒的条件下[3]。 |
In Vivo |
Ro 48 -8071 在每天 150 μmol/kg 时最大程度地降低约 60% 的 LDL-C,在每天 300 μmol/kg 时不会进一步降低,而 HDL-C 在仓鼠中的所有剂量下均保持不变。Ro 48 -8071 (每天≥00 μMol/kg) 增加仓鼠肝脏中的 MOS 量。Ro 48 -8071 (每天 300 μmol/kg) 显著降低仓鼠的 VLDL 分泌[1]。Ro 48 -8071 (5 或 20 mg/kg) 显著减少小鼠体内肿瘤的生长,而小鼠体重没有减轻。此外,浓度为 20 mg/kg 的 Ro 48 -8071 在测试的时间范围内完全根除了小鼠中监测的 12 种肿瘤中的两种[2]。Ro 48 -8071 (20 毫克/天/千克体重) 导致 BALB/c 小鼠整个小肠中胆固醇合成的快速和持续抑制 (>50%)。大肠和胃中的甾醇合成也减少[4]。 |
动物实验 |
Six-week-old male athymic nude mice (nu/nu) weighing 20-22 g are used in the assay. Castration-resistant PC-3 cells (5×106 in 0.15 mL solution) are mixed with matrigel and RPMI-1640 medium (1/1, v/v) and injected subcutaneously into both flanks of each mouse (n=6 animals/group) and tumors allowed to develop. The tumors are measured twice per week with a digital caliper. Tumor volumes are calculated by the formula (L × W × H) × π/6. Drug treatment is started when tumor volumes reach appr 100 mm3. Mice are given daily tail vein injections of 0.1 mL solution of either 5 or 20 mg/kg Ro 48-8071 for 5 days. This is followed by an injection every other day for six additional treatments and then a final injection 2 hours prior to sacrifice. Control mice receive the same volume of phosphate-buffered saline on the same schedule. The animals are weighed and tumor volumes are measured twice weekly throughout the drug treatment period. |
