Pro-Apoptotic Activity of Bioactive Compounds from Seaweeds: Promising Sources for Developing Novel Anticancer Drugs.
Marine Drugs 2023 March 16
The process by which cancer cells evade or inhibit apoptosis is considered one of the characteristics of cancer. The ability of cancer cells to escape apoptosis contributes to tumor proliferation and promotes metastasis. The discovery of new antitumor agents is essential for cancer treatment due to the lack of selectivity of drugs and cellular resistance to anticancer agents. Several studies showed that macroalgae produce various metabolites with different biological activities among marine organisms. This review discusses multiple metabolites extracted from macroalgae and their pro-apoptotic effects through regulating apoptosis signaling pathway target molecules and the structure-activity relationship. Twenty-four promising bioactive compounds have been reported, where eight of these compounds exhibited values of maximum inhibitory concentration (IC50) of less than 7 μg/mL. Fucoxanthin was the only carotenoid reported that induced apoptosis in HeLa cells with an IC50 below 1 µg/mL. Se-PPC (a complex of proteins and selenylated polysaccharides) is the magistral compound because it is the only one with an IC50 of 2.5 µg/mL which regulates the primary proteins and critical genes of both apoptosis pathways. Therefore, this review will help provide the basis for further studies and the development of new anticancer drugs, both as single agents and adjuvants, decreasing the aggressiveness of first-line drugs and offering patients better survival and quality of life.
