产品描述

CHMFL-PI3KD-317 is a highly potent, selective and orally active PI3Kδ inhibitor, with an IC50 of 6 nM, and exhibits over 10-1500 fold selectivity over other class I, II and III PIKK family isoforms, such as PI3Kα (IC50, 62.6 nM), PI3Kβ (IC50, 284 nM), PI3Kγ (IC50, 202.7 nM), PIK3C2A (IC50, >10000 nM), PIK3C2B (IC50, 882.3 nM), VPS34 (IC50, 1801.7 nM), PI4KIIIA (IC50, 574.1 nM) and PI4KIIIB (IC50, 300.2 nM). CHMFL-PI3KD-317 inhibits PI3Kδ-mediated Akt T308 phosphorylation in Raji cells, with an EC50 of 4.3 nM. CHMFL-PI3KD-317 has antiproliferative effects on cancer cells[1].

CHMFL-PI3KD-317 has antiproliferative effects, with GI50s of 3.5?±?0.8, 4.0?±?0.9, 4.8?±?0.2, 3.3?±?0.2, 3.0?±?0.4 μM against PF382, NALM-6, MV4-11, MOLM-14 and MOLM-13 cells, respectively[1].

CHMFL-PI3KD-317 (Compound 15i; 25, 50 and 100?mg/kg/day, p.o., for 14 days) inhibits the growth of the MOLM14 tumor in mice[1].
CHMFL-PI3KD-317 shows favorable oral bioavailability and acceptable half-life (T1/2?=?3.28?h) in Sprague-Dawley rats[1].

Animal Model: Female nu/nu mice bearing MOLM-14 tumor xenografts[1]
Dosage: 25, 50 and 100?mg/kg/day
Administration: P.O. for 14 days
Result: Inhibited the growth of the MOLM14 tumor without mortality or obvious weight loss in mice.

Research Update

Discovery of (S)-2-amino-N-(5-(6-chloro-5-(3-methylphenylsulfonamido)pyridin-3-yl)-4-methylthiazol-2-yl)-3-methylbutanamide (CHMFL-PI3KD-317) as a potent and selective phosphoinositide 3-kinase delta (PI3Kδ) inhibitor

Eur J Med Chem 2018 Aug 5;156:831-846.PMID:30053721DOI:10.1016/j.ejmech.2018.07.036

PI3Kδ, which is mainly expressed in leukocytes, plays a critical role in B-cell receptor mediated signaling pathway and has been extensively studied as a drug discovery target for B cell malignances such as AML, CLL etc. In this manuscript, we report the discovery, SAR optimization and pharmacological evaluation of a novel series of aminothiazole-pyridine containing PI3Kδ inhibitors. Among them compound 15i (CHMFL-PI3KD-317) displays an IC50 of 6 nM against PI3Kδ in the ADP-Glo biochemical assays. It also exhibits over 10-1500 fold selectivity over other class I, II and III PIKK family isoforms. In addition, in the cellular context, 15i can selectively and potently inhibit PI3Kδ mediated phosphorylation of Akt T308 but not PI3Kα, β, γ mediated Akt phosphorylation. 15i also exhibits an excellent selectivity profile in the protein kinases including 468 kinases/mutants at the concentration of 1 μM. 15i has acceptable pharmacokinetic properties and can dose-dependently inhibit the tumor growth of AML cell line MOLM14 inoculated xenograft mouse model. The high selectivity and potency makes 15i a potential valuable addition to the current PI3Kδ armory.
