Abstract: In order to show antiproliferation and cancerous cell growth inhibition of quinazoline derivatives, a series of 2-(chloromethyl)-3-phenylquinazolin-4(3H)-ones (H1–H11) were synthesized. In vitro cytotoxic activities were evaluated against three human cancer cell lines: A549, MCF-7 and SW1116 using colorimetric MTT assay. Comparing their effects together and with cisplatin as a positive control indicated that H3, H5 and H6 exhibited better antitumor activities on A549 cell line with IC50 values less than 10?μM versus 12?μM for cisplatin. In the case of MCF-7 and SW1116 cell lines, almost all compounds displayed better cytotoxic activities than cisplatin. Molecular docking studies were applied on epidermal growth factor receptor (EGFR) as the main target of quinazoline scaffolds in cancer therapy to predict the binding energies, binding modes and orientation of these ligands toward the active site of the receptor. In silico physicochemical parameters and ADMET profiling calculations also were done. All compounds showed lower binding energies than erlotinib, the inhibitor of EGFR. Taken together, our findings showed potential anticancer effect of quinazoline compounds bearing various phenyl ring substitutions. Graphic abstract: [Figure not available: see fulltext.]

Two novel series of quinazolinone-pyrimidine (series a: 9a-9i) and benzyl-pyrimidine hybrids (series b: 12a-12c) were designed, synthesized and characterized by spectroscopic methods. The dipeptidyl peptidase-4 inhibition potencies of these compounds were assessed through a MAK 203 kit. Compound 9e was found to be the most potent agent with an IC50 value of 34.3 ± 3.3 μM. A kinetic study revealed that it acted as a competitive inhibitor. Molecular modeling of these compounds was in agreement with the in vitro results. Due to the crucial role of dipeptidyl peptidase-4 in cancer therapy, the cytotoxic activities of the compounds were also evaluated against three cancerous cell lines (HT-29, SW1116 and A549). Almost all the compounds displayed better antiproliferative activity on colon cancer cell lines (HT-29 and SW1116) compared to a lung cancer cell line (A549). Compounds 9e and 12c exhibited significant activity toward the HT-29 cell line with an IC50 of 10.67 ± 0.3 μM and 27.9 ± 6.5 μM in comparison to sitagliptin and cisplatin as a positive control, respectively. Among the different cells, the compounds showed the best inhibitory effects on HT-29, which was compatible with the greater expression of the dipeptidyl peptidase-4 marker detected by flow cytometry in this cell line. Further studies on the hit compounds (9e and 12c) through cell cycle and apoptosis assays also showed that these compounds could induce cell death by apoptosis or arrest cells in the G2/M phase. Accordingly, the results imply that 9e is a potent inhibitor of dipeptidyl peptidase-4 with efficient anti-cancer activity and could play a role as a cytotoxic agent in colorectal cancer.

Aseries of novel thioglycoside derivatives containing 4(3H)-quinazolinone was designed and synthesized from 2-chloromethyl-quinazolin-4(3H)-ones and 1-thioglycose. Several 2-chloromethyl-quinazolin-4(3H)-ones were synthesized on refluxing with 2-(chloroacetylamino)-benzoic acid and arylamines in acetonitrile. All of the novel compounds were characterized by IR, 1H NMR spectra and elemental analysis. The structures of compounds 7b, 8b and 8c have been determined by X-ray diffraction analysis.

Stereoselective diazotization of (S)-2-amino-2-phenyl acetic acid (L-phenyl glycine) (4) with NaNO2 in 6% H2SO4 in a mixture of acetone and water gave optically pure (S)-2-hydroxy-2-phenyl acetic acid (L-mandelic acid) (5). Esterification, gave (S)-2-hydroxy-2-phenyl acetic acid esters (6). The latter was treated with chloroacetyl chloride in the presence of triethylamine (TEA) in dichloromethane (DCM) to yield (S)-2-chloroacetyloxy phenyl acetic acid ester (2). In another sequence, the reaction of 2-(chloromethyl)-3-arylquinazolin- 4(3H)-one (9) treated with N-Boc piperazine, followed by deprotection of the Boc group, to obtain 3-aryl-2-((piperazin-1-yl)methyl) quinazolin-4(3H)-one (3). Reaction of 2 with 3 in the presence of K2CO3 and KI gave the title compound, 2-(2-(4-((3,4-dihydro-4-oxo-3-arylquinazolin-2-yl)methyl)piperazin-1-yl) acetoyloxy)-2-phenyl acetic acid esters (1). The structures of all the new compounds obtained in the present work are supported by spectral and analytical data. Copyright Taylor & Francis Group, LLC.
