Synthesis of novel 1,4-Dihydropyridine derivative labeled with Carbon-14

Synthesis of 14</sup>C-labeled organic compounds is being required by the medical, pharmaceutical, agricultural, industrial, and research centers. The Carbon-14 is essential for the tracking and recognizing the mechanism and performance of the synthesized chemical compounds. The Dihydropyridine is synthetically labeled with Carbon-14 in this work to pursue a further study about the mechanism of its action and to support the current metabolism. Therefore, to clarify further the mechanism of its operation and to support the current research on its metabolism, there is a need for the analogs of these compounds that are Carbon-14 labeled in a biologically stable site. The 1,4-Dihydropyridine channel blockers are clinically significant antihypertensive drugs and have been immensely valuable as molecular tools to probe into the structural and functional aspects of the channel function. In this study, N-Phenyl-3,5-Dicarboxylate-2,4,6-Triphenyl-1,4[14</sup>C]-Dihydropyridine, which is a new compound of the Dihydropyridine derivative and had labeled with the Carbon-14, was synthesized. This novel synthetic compound having an N-Phenyl derivative is one of the new drug metabolites that have anti-cancer properties. Using a multicomponent reaction with the shortest stage in the preparation, separation, and purification, as well as, suitable conditions with an encellent radiochemical yield was developed.
