產品介紹

AMG319 is a potent and selective PI3Kδ kinase inhibitor with IC50 of 18 nM.

產品描述：

AMG319 is a potent and selective PI3Kδ kinase inhibitor with IC50 of 18 nM.

靶點：

PI3Kδ:18 nM (IC50);PI3Kγ:850 nM (IC50);PI3Kβ:2.7 μM (IC50);PI3Kα:33 μM (IC50);PI3K

體外研究：

AMG319 inhibits PI3Kδ, PI3Kγ, PI3Kβ and PI3Kα with IC50s of 18 nM, 850 nM, 2.7 μM and 33 μM, respectively. AMG319, a compound with an IC50 of 16 nM in a human whole blood assay (HWB), excellent selectivity over a large panel of protein kinases, and a high level of in vivo efficacy as measured by two rodent disease models of inflammation. AMG319 has minimal CYP3A4/2D6 inhibition and does not inhibit CYPs (1A2, 2C8, 2C9, 2C19, 2E1, all >20 μM). There is no time dependent inhibition (TDI) against CYPs 3A4, 2D6, 1A2, and 2C9 nor CYP induction (3A4, 2D6, 1A2, 2B6) as measured in hepatocytes. AMG319 is clean in a hERG binding assay (>25 μM), and an Ames micronucleus test proved negative. AMG319 has minimal effects in a BSEP assay up to >200 μM. Additionally, AMG319 is clean in a large side effect profiling panel (CEREP) and has no activity in a large panel of 359 unique protein kinases tested at 10 μM drug concentration

體內研究：

The study is performed to determine the correlation between biochemical coverage (i.e., pAKT) with functional activity in vivo. AMG319 achieves this coverage at the 3 mg/kg level, which also coveres the human whole blood assay (HWB) (CD-69) IC90 at trough for a full 24 h period. The lower doses 0.1, 0.3, and 1 mg/kg cover trough concentrations between the HWB IC50 and IC90 and evince partial efficacy. Similarly, the plasma concentration of AMG319 covers the IC90 at the 1 mg/kg dose of the mouse anti-IgM pAKT in vitro assay

細胞實驗：

Cells are seeded in 96-well plates at 2,000 (Sup-T1, Jurkat, and DND-41) or 10,000 (HPB-ALL or TALL-1) cells/well in growth media supplemented with 10% fetal bovine serum. Serial dilutions of Nirogacestat (PF-03084014) are done in DMSO, appropriate controls or designated concentrations of Nirogacestat (PF-03084014) are added to each well, and cells are incubated at 37°C for 7 days (final DMSO content 0.1%). Resazurin at a final concentration of 0.1 mg/mL is added to the cells and plates are incubated for 2 to 4 hours. Fluorescent signals are read as emission at 590 nm after excitation at 560 nm. IC50 values are calculated by using the sigmoidal dose-response (variable slope) in GraphPad Prism.

動物實驗：

Mice Athymic female mice (nu/nu, 6-8 weeks) are used. For antitumor efficacy, animals bearing tumors of 150 to 300 mm3 in size are randomly divided into groups that received either vehicle (0.5% methylcellulose) or Nirogacestat (PF-03084014) (150 mg/kg, diluted in vehicle), and dosed by oral gavage. Animal body weight and tumor measurements are obtained every 2 to 3 days. Tumor volume (mm3) is measured with Vernier calipers and calculated. Percent (%) inhibition values are measured on the final day of study for drug-treated compared with vehicle-treated mice and are calculated. For all tumor growth inhibition experiments, 8 to 10 mice per dose group are used. Student's t test is used to determine the P value.
