Abstract:

Heterocyclic molecules containing 1,2,4-triazole motif are important for drug screening due to their better broad spectrum of bioactivities. For structure-activity relationship study, twenty-eight novel multi-heterocyclic molecules [TM1TM3(af)] and [TM4TM5(ae)] containing duo 1,2,4-triazole motifs were synthesized by the conjugation with piperazine and s-triazine, respectively. The structures of target molecules were confirmed via infrared(IR), proton nuclear magnetic resonance(1H NMR) and high resolution mass spectrometry(HRMS). In order to investigate the effect of 4-amino substituent on 1,2,4-triazole for bioactivities, the comparison between compounds 6-morpholine-2,4-(5-thioether-4-amino-3-n-pentyl-1,2,4-triazole)-1,3,5-triazine(C), 6-pyrrole-2,4-(5-mercapto-4-amino-3-n-pentyl-1,2,4-triazole)-1,3,5-triazine(D) and target molecules were also performed. The inhibitory activities against cell division cycle protein 25B(Cdc25B) phosphatases of synthesized molecules were evaluated. Twenty one molecules exhibit good activities, and nine among them are more potent than the positive control Na3VO4.
