The phosphoinositide 3-kinase (PI3K) family is one of the most frequently activated enzymes in a wide range of human cancers; thus, inhibition of PI3K represents a promising strategy for cancer therapy. Herein, a series of benzylamine substituted arylsulfonamides were designed and synthesized as dual PI3K/mTOR inhibitors using a strategy integrating focused library design and virtual screening, resulting in the discovery of 13b (NSC765844). The compound 13b exhibits highly potent enzyme inhibition with IC50s of 1.3, 1.8, 1.5, 3.8 and 3.8 nM for PI3Kα, β, γ, δ, and mTOR, resp. 13b was further evaluated in NCI by an in vitro cytotoxic screening program. Broad-spectrum antitumor activities with mean GI50 value of 18.6 nM against approx. 60 human tumor cell lines were found. 13b displayed favorable physicochem. properties and superior pharmacokinetic profiles for animal studies. It significantly inhibited tumor growth when administered orally in an A549 non-small-cell lung carcinoma xenograft and BEL7404 human hepatocellular carcinoma xenograft models. On the basis of its excellent in vivo efficacy and superior pharmacokinetic profiles, 13b has been selected for further preclin. investigation as a promising anticancer drug candidate.
European Journal of Medicinal Chemistry published new progress about Antitumor agents. 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, SDS of cas: 112-63-0.
