Abstract:

Natural products derived from marine sponges such as spermatinamine analogues have gained a lot of attention due to their unique biochemistry. Herein, a library of spermatinamine analogues has been designed and synthesized. The lead compounds were screened for their in vitro activity on cervix adenocarcinoma (HeLa), breast adenocarcinoma (MCF-7), and prostate carcinoma (DU145) cell lines at different time intervals. Among the twelve novel compounds, 5 compounds were found to be potent in terms of IC50 in mM range. The obtained results suggest that longer polyamine linkers together with hydrophobic oxime substitution provided the most potent and selective compounds < 10 mM against cancer cell lines.
