Synthesis, Antitumor Activity, and Docking Study of 1,3-Disubstituted Imidazolium Derivatives
摘要:
A series of 1,3-disubstituted imidazolium salts were synthesized through a convenient synthetic approach based on the reaction of 1,4-diazabuta-1,3-dienes with HClO4. Their antitumor activity was evaluated in vitro against a number of human cancer cells. 1,3-Bis[(3,5-bis(trifluoromethyl)phenyl]imidazolium perchlorate turned out to be the most active against A549 and MCF-7 cancer cell lines with IC50 values of 5.24 and 4.21 mu M, respectively. The results of structure-activity relationship study indicated that substituents on the imidazole derivatives play an important role in their cytotoxic activities. Finally, molecular docking of some tested compounds was carried out in order to investigate their binding pattern with the CDK2.

were employed as catalysts for hydrodechlorination of the chloroarenes p-dichlorobenzene and hexachlorobenzene. When optimized, the foregoing approach is significantly more effective than those of currently known transition metal carbene complexes. The most active catalysts were found to be the monocarbene complexes of palladium chloride and iodide, both of which feature highly branched aromatic substituents

The reactions of 1,4‐diazabutadienes 1 with HClO4 were studied in detail. The final products obtained were not the hydroperchlorates of 1 but imidazolium perchlorates 2 or 3. A possible reaction process is postulated on the basis of the isolation of the intermediate 2‐iminomethylimidazolium salt 4. The factors influencing the conversion of 4 to the imidazolium perchlorates 2 and 3 were discussed with
