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
Design, synthesis, molecular simulation, and biological activities of novel quinazolinone-pyrimidine hybrid derivatives as dipeptidyl peptidase-4 inhibitors and anticancer agents
Twelve novel quinazolinone–pyrimidine hybrids were synthesized, of which some of them showed dual functions as DPP-4 inhibitors and anti-cancer agents.
合成了十二种新型喹唑啉基-嘧啶杂化物,其中一些显示出双重功能,既是DPP-4抑制剂又是抗癌药物。
Chlorotrimethylsilane-Mediated Synthesis of 2-Aryl-1-chloro-1-heteroarylalkenes
The condensation of (chloromethyl)heterarenes with aromatic aldehydes was investigated, resulting in a simple and flexible general procedure for the synthesis of 2-aryl-1-chloro-1-heteroarylalkenes. The best reaction conditions were found to be heating in N,N-dimethylformamide in the presence of chlorotrimethylsilane as a promoter and water-scavenger.

A novel series of quinazoline clubbed thiazoline derivatives was rationally designed and synthesized. The newly synthesized compounds were evaluated for in vitro dipeptidyl peptidase IV (DPP‐4) inhibitory activity. Compounds that showed good to moderate activity were compared using linagliptin as standard. Compound 4x (IC50 = 1.12 nM) exhibited the most promising results. The special chemical feature
The present invention relates to erastin analogs, particularly compounds of formulae VI, VIa, VII, and VIIa, as well as compounds 19, 20, and 20. The invention also relates to pharmaceutical compositions containing such analogs and to methods of treating a condition in a mammal with such analogs and compositions.
