AMG 511 是一个高效、口服有效的 I 类pan-PI3K抑制剂,对 PI3Kα, β, δ 和 γ 作用的Ki值分别为 4 nM, 6 nM, 2 nM 和 1 nM。AMG 511 减少 p-Akt (Ser473), 体现了它显著抑制了 PI3K 信号。AMG 511 在小鼠胶质母细胞瘤移植瘤模型中具有抗肿瘤活性。
生物活性 | AMG 511 is a potent and orally available pan inhibitor of class IPI3Ks, withKis of 4 nM, 6 nM, 2 nM and 1 nM forPI3Kα, β, δ and γ, respectively. AMG 511 significantly suppressesPI3Ksignaling that is indicated by p-Akt (Ser473) decrease. AMG 511 exhibits anti-tumor activity in mouse glioblastoma xenograft model[1]. |
IC50& Target | PI3Kα 4 nM (Ki) | PI3Kβ 6 nM (Ki) | PI3Kδ 2 nM (Ki) | PI3Kγ 1 nM (Ki) |

体外研究 (In Vitro) | AMG 511 shows the inhibition of AKT (Ser473) phosphorylation in U87 malignant glioma (MG) cells with an IC50of 4 nM[1].
|
体内研究 (In Vivo) | AMG 511 potently blocks the targeted PI3K pathway in a mouse liver pharmacodynamic model (3-30 mg/kg; p.o.) and inhibits tumor growth in a U87 MG glioblastoma xenograft model (3-30 mg/kg; p.o.; daily; for 12 days)[1]. AMG 511 shows excellent in vivo efficacy and pharmacokinetic profile[1].
Animal Model: | Female CD1 NU/NU mice, with U87 MG glioblastoma xenograft model[1] | Dosage: | 1 mg/kg, 3 mg/kg, 10 mg/kg | Administration: | Oral administration, daily, for 12 days | Result: | Inhibited tumor growth. |
Animal Model: | Male Sprague-Dawley rats[1] | Dosage: | 1 mg/kg | Administration: | Oral administration (Pharmacokinetic Analysis) | Result: | Had a superior pharmacokinetic profile with low clearance (0.4 L/h/kg, 12% of liver blood flow), good oral bioavailability (F = 60%), and a commensurate high oral exposure (AUC = 5.0 μM·h). |
