Likewise, imidazole’s induction of apoptosis in HL60 cells was associated with intracellular acidification, caspase-3 activation, and DFF-45 cleavage, which demonstrated the induction of caspase-dependent cell death [29,36], that is in agreement using the observations noticed with compound 9 in our study.IRF5 Protein site Figure 7.GAS6 Protein web (a) The effect of compound 9 on MDA-MB-231 cell viability, (b) The effect of compound2.PMID:24238102 two. Computational Research two.two.1. Anti-Cancer Activity and Molecular Target Prediction The PASS On-line net server was utilised to predict the anti-cancer activity in the 14 compounds. As shown in Table three, compounds 81, 13, and 14 demonstrated the highest probability as prospective anti-cancer agents, though the rest showed low-to-inactive activity predictions. Additionally, the possible molecular targets for the synthesized compounds had been predicted applying the SEA Search. A greater similarity score (maxTC) having a lower significance score (p-value) indicates a greater probability that the protein is actually a prospective target. This study focused on tubulin as a potential target due to the fact earlier reports identified imidazole-based derivatives as tubulin polymerization inhibitors [370]. Table 3 shows that compounds 8 and 9 possessed a higher maxTC score (0.32 and 0.34, respectively) having a low p-value (1.544 10-6 and 1.137 10-6, respectively), indicating potential interference with microtubule-associated protein tau, whichMolecules 2022, 27,11 ofstabilizes the microtubule bundles and modulates the microtubule network assembly [41]. Compounds 11 and 13 had been also predicted to possess anti-cancer activity. Nevertheless, the in vitro studies demonstrated that these compounds were far much less potent than compounds eight and 9.Table three.
