Abstract: Organoselenocyanates are important classes of organoselenium compounds having potential pharmaceutical applications in cancer biology. In the present study, two different series of organoselenocyanates (15 a-15 c and 16 a-16 c) incorporating crucial heterocyclic pharmacophores such as 2,4-thiazolidine-1,3-dione and 1,2,3-triazole were rationally designed. The organoselenocyanates were synthesized using multi-step organic synthesis and investigated for their anticancer activities against triple-negative breast cancer cells. Based on the preliminary anti-proliferative activities and the selectivity index towards cancer cells over the normal cells, 2,4-thiazolidine-1,3-dione-based selenocyanate 15 a was identified as the lead analogue for detailed investigations. In addition to the anti-migratory activity, compound 15 a induced G1-phase arrest of the cell cycle and led to early apoptosis. Further studies on the redox balance of MDA-MB-231 cells indicated the antioxidant nature of 15 a with the quenching of ROS level and upregulation of TrxR1 expression. Detailed mechanistic investigations with the expression levels of key-cancer marker proteins revealed that the selenocyanate 15 a induced the activation of ERK pathway by upregulating p-ERK expression with the subsequent downregulation of p-Akt and c-Myc levels leading to the inhibition of cellular proliferation. Therefore, the primary outcomes of the study would be valuable in the development of chemotherapeutic agents towards the treatment of triple-negative breast cancer.
