体外研究
(In Vitro)

PF-4989216 (Compound 10) has excellent PI3Kα K_i(0.6 nM), good cellular potency (S473 IC₅₀=79 nM), and good selectivity against mTOR (mTOR K_i=1440 nM). PF-4989216 has PI3Kα K_iless than 1 nM and mTOR K_imore than 1 μM. PF-4989216 also has excellent selectivity over 40 other kinases, and no major CYP inhibitions are observed. Less than 30% inhibition is observed in 1A2, 2C9, 2D6, and 3A4 CYP enzymes at 3 μM^[1]. The toxicity of PF-4989216 in several drug-sensitive and MDR cancer cell lines, including cells overexpressing ABCB1 or ABCG2, and in HEK293 cells transfected with human ABCB1 or ABCG2 is determined. PF-4989216 inhibits human colon carcinoma S1 cell line and ABCG2-overexpressing subline S1-M1-80 with IC₅₀s of 1.11±0.09 and 6.79±1.00 uM, respectively. PF-4989216 inhibits human breast carcinoma MCF-7 and ABCG2-overexpressing sublines MCF7-FLV1000 and MCF7-AdVp3000 IC₅₀s of 2.30±0.68, 23.26±2.94 and 62.57±5.46 uM, respectively. PF-4989216 inhibits pcDNA-HEK293, ABCB1-transected MDR19-HEK293, ABCG2-tranfected R482-HEK293 cells with IC₅₀s of 0.44±0.05, 0.38±0.06 and 5.05±0.89 uM, respectively^[2].

体内研究

1.
请依序添加每种溶剂： 10% DMSO 40%PEG300 5%Tween-80 45% saline
Solubility: ≥ 2.5 mg/mL (6.57 mM); Clear solution
此方案可获得 ≥ 2.5 mg/mL (6.57 mM，饱和度未知) 的澄清溶液。
以 1 mL 工作液为例，取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中，混合均匀；向上述体系中加入50 μL Tween-80，混合均匀；然后继续加入 450 μL生理盐水定容至 1 mL。
将 0.9 g 氯化钠，完全溶解于 100 mL ddH2O 中，得到澄清透明的生理盐水溶液
