Hazard Information | Back Directory | [Description]
A-66 is a potent, selective inhibitor of the PI3K isoform p110α (IC50 = 32 nM in a cell-free assay).1 It displays over 100-fold selectivity for p110α over other isoforms. A-66 is effective in vivo, suppressing the growth of SK-OV-3 tumor xenografts in mice.1 It also impairs all measures of in vivo insulin action in mice.2 A-66 partially suppresses B cell receptor-dependent Akt activation and proliferation.3 | [Uses]
A66 is a potent and specific p110α inhibitor. Inhibition of p110α can block phosphoinositide 3-kinase (PI3K) signalling and tumor growth in certain cell types. | [Definition]
ChEBI: (2S)-N1-[5-(2-tert-butyl-4-thiazolyl)-4-methyl-2-thiazolyl]pyrrolidine-1,2-dicarboxamide is a proline derivative. | [Enzyme inhibitor]
This potent and highly selective p110α inhibitor (FW = 393.53; CAS
1166227-08-2; Solubility: 79 mg/mL DMSO, 1 mg/mL H2O), also known
as (2S) -N1- (5- (2-tert-butylthiazol-4-yl) -4-methylthiazol-2-yl) pyrrolidine-1,
2-dicarboxamide, has a IC50 value of 32 nM for the wild-type
phosphoinositide-3 kinase p110 α as well as oncogenic forms of p110α
such as p110α E545K (IC50 = 43 nM) and p110α H1047R (IC50 = 43 nM)
. A66 inhibition also demonstrated that cancer-specific mutations in the
iSH2 (inter-SH2) and nSH2 (N-terminal SH2) domains of p85α, the
regulatory subunit of phosphatidylinositide 3-kinase (PI3K), show gain of
function, inducing oncogenic cellular transformation, stimulating cellular
proliferation, and enhancing PI3K signaling. | [storage]
