Aberrant activation of FMS-like tyrosine receptor kinase 3 (FLT3) is implicated in the pathogenesis of acute myeloid leukemia (AML) in 20–30% of patients. In this study we identified a highly selective (phenylethenyl)quinazoline compound family as novel potent inhibitors of the FLT3-ITD and FLT3-D835Y kinases. Their prominent effects were confirmed by biochemical and cellular proliferation assays followed by mice xenograft studies. Our modelling experiments and the chemical structures of the compounds predict the possibility of covalent inhibition. The most effective compounds triggered apoptosis in FLT3-ITD AML cells but had either weak or no effect in FLT3-independent leukemic and non-leukemic cell lines. Our results strongly suggest that our compounds may become therapeutics in relapsing and refractory AML disease harboring various ITD and tyrosine kinase domain mutations, by their ability to overcome drug resistance.

The ecto-nucleotide pyrophosphatase/phosphodiesterase-1 (NPP1) was recently shown to promote mineralization of the aortic valve, hence, its inhibition represents a significant target. A quinazoline-4-piperidine sulfamide compound (QPS1) has been described as a specific and non-competitive inhibitor of NPP1. We report herein the synthesis and in vitro inhibition studies of novel quinazoline-4-piperidine sulfamide analogues using QPS1 as the lead compound. Of the 26 derivatives prepared, four compounds were found to have Ki 105 nM against human NPP1.

A series of novel quinazolinone hybrids were synthesized by employing click chemistry and evaluated for anti-proliferative activities against MCF-7, HeLa and K562 cell lines. Among these cell lines, HeLa cells were found to respond effectively to these quinazolinone hybrids with IC50 values ranging from 5.94 to 16.45 μM. Some of the hybrids (4q, 4r, 4e, 4k, 4t, 4w) with promising anti-cancer activity were further investigated for their effects on the cell cycle distribution. FACS analysis revealed the G1 cell cycle arrest nature of these hybrids. Further to assess the senescence inducing ability of these compounds, a senescence associated β-gal assay was performed. The senescence inducing nature of these compounds was supported by the effect of hybrid (4q) on p16 promoter activity, the marker for senescence. Moreover, cells treated with most effective compound (4q) show up-regulation of p53, p21 and downregulation of HDAC-1, HDAC-2, HDAC-5 and EZH2 mRNA levels. Docking results suggest that, the triazole nitrogen showed Zn+2 mediated interactions with the histidine residue of HDACs.

The mutant p53 proteins and their corresponding cellular response can be manipulated by novel quinazolinone derivatives 4-8 (a-i) in p53 mutant cancer cells. Of the two most potent compounds, 4a exhibited promising broad-spectrum anti-cancer effects, whereas 6c showed selective and exclusive inhibition activity in p53 mutant cancer cell lines but low toxicity to wild-type p53 cancer cell A375 and normal lung fibroblast WI-38 cells. Furthermore, 6c exhibited a more sophisticated mechanism for cell-destructive response by causing S/G2 phase arrest effect and cell size reduction. Compared with the cellular response of 6b and genetic background of cell lines studied, p53 mutation was found to be the key factor and main target for 6c evoked cell-destructive response. Molecular mechanism studies indicated that p53 phosphorylation and acetylation dual-targeting inhibitor 6c exerted anti-cancer activities with a special mechanism in evoking cell apoptosis by arresting mutant p53 function to trigger the deregulation of Cdk2 caused Bim-mediated apoptosis. To the best of our knowledge, 6c is the first quinazolinone derivative to dictate mutant p53 function for apoptotic cell death.

The reactivity of variably substituted 2-methyl-4H-3,1-benzoxazin-4-ones and 2-methyl-4H-pyrido[2,3-d][1,3]oxazin-4-one towards carbon and oxygen nucleophiles under microwave irradiation conditions was investigated. Optimization of the reaction conditions of oxazinones with carbon nucleophiles led to the synthesis of a series of 4-hydroxy-quinolin-2-ones and 4-hydroxy-1,8-naphthyridin-2-ones in high yields, whereas reaction with a variety of alcohols proceeded smoothly to the formation of the corresponding N-acetyl-anthranilates and nicotinates.

Organofluorine compounds are of high interest in modern drug discovery and material sciences. We herein report a new synthetic access to o-amino-2,2,2-trifluoroacetophenones starting from commercially available o-amino benzoic acids, which can easily be converted into the corresponding benzoxazinones. In a second step the trifluoromethylated ketone is formed via addition of Ruppert's reagent following acidic work up.

We describe a new class of subunit-selective antagonists of N-methyl d-aspartate (NMDA)-selective ionotropic glutamate receptors that contain the (E)-3-phenyl-2-styrylquinazolin-4(3H)-one backbone. The inhibition of recombinant NMDA receptor function induced by these quinazolin-4-one derivatives is noncompetitive and voltage-independent, suggesting that this family of compounds does not exert action on the agonist binding site of the receptor or block the channel pore. The compounds described here resemble CP-465,022 ((S)-3-(2-chlorophenyl)-2-[2-(6-diethylaminomethyl-pyridin-2-yl)-vinyl] -6-fluoro-3H-quinazolin-4-one), a noncompetitive antagonist of AMPA-selective glutamate receptors. However, modification of ring substituents resulted in analogues with greater than 100-fold selectivity for recombinant NMDA receptors over AMPA and kainate receptors. Furthermore, within this series of compounds, analogues were identified with 50-fold selectivity for recombinant NR2C/D-containing receptors over NR2A/B containing receptors. These compounds represent a new class of noncompetitive subunit-selective NMDA receptor antagonists.

Piriqualone (1) was found to be an antagonist of AMPA receptors. Structure-activity optimization was conducted on each of the three rings in 1 to afford a series of potent and selective antagonists. The sterically crowded environment surrounding the N-3 aryl group provided sufficient thermal stability for atropisomers to be isolated. Separation of these atropisomers resulted in the identification of (+)-38 (CP-465,022), a compound that binds to the AMPA receptor with high affinity (IC50 = 36 nM) and displays potent anticonvulsant activity.
