Abstract

Novel almazole D–amide conjugates, esters, and N-alkylated analogs were synthesized and investigated for their anticancer activity against seven cancer cell lines. Among the series, compounds 5g and 5m showed significant anticancer activities against multiple cell lines with moderate selectivity indices. Compound 5g had IC50 values of 5.86 ± 0.31, 9.94 ± 0.06, 12.74 ± 0.12, and 9.40 ± 0.03 μM against the B16-F10, DU145, HeLa, and LC-540 cell lines, respectively, while compound 5m showed IC50 values of 6.35 ± 0.09, 9.17 ± 0.11, 9.00 ± 0.011, 19.65 ± 0.63, 8.13 ± 0.04, and 11.56 ± 0.01 μM against B16-F10, DU145, HeLa, HepG2, LC-540, and SK-BR-3 cells, respectively. Compared to almazole D, which only showed significant activity against B16-F10 cells (IC50 = 9.05 ± 0.008 μM), the synthesized analogs showed improved anticancer activity against multiple cell lines. The kinase inhibition assay coupled with the docking studies revealed that epidermal growth factor receptor (EGFR) kinase inhibition via interaction with amino acid residue T790 on the EGFR is one of the possible mechanisms by which 5g exerts its anticancer potential. The ADMET prediction and drug-likeness of the analogs project the synthesized analogs as promising agents, which can be further developed for application in cancer therapy.
