A simple and reliable methodology is described for preparing the first heterogeneous NNN-pincer-copper hybrid catalyst with a high control over surface composition. The strategy relies on the covalently bonding of 2-aminopyridine to cyanuric chloride-functionalized magnetic nanoparticles followed by complexation with CuI. These claims are confirmed by different characterization methods such as SEM, TEM, FT-IR, TGA, ICP, XRD, and elemental analysis. The finely engineered supported catalyst is employed in the aerobic oxidative coupling of terminal alkynes and click reaction using only 0.38 and 0.04 mol% catalyst, respectively. All reactions perform under solvent-free condition or green solvent H2O. Also, the catalyst is readily recovered and reused for up to 8 and 6 subsequent runs in click and homocoupling reactions without significant loss of activity or leaching.

Breast cancer, a leading cause of mortality in women, warrants the development and biological evaluation of new anticancer agents. A novel series of thiopyridine triazine derivatives was synthesized and investigated in the human breast cancer cell line, MDA-MB-468. SM40, the most potent derivative, induced a G2/M arrest and apoptosis with a possible involvement of p53. The cytotoxicity of SM40 was also examined against the NCI 60 cell line panel and its potency was rationalized using molecular modeling. Results suggest that SM40 is a promising cytotoxic agent.
