Abstract

Cancer was the leading cause of death, which accounting for nearly 10 million deaths globally in 2020. Currently, cancer treatment still relies on chemotherapy, however, most anticancer drugs showed non-specific toxicity to normal cell proliferation resulting in various side effects, and are ineffective against many forms of cancer. In addition, the increasing case of chemoresistance of cancer cells to chemotherapy has boosted the discovery of new anticancer agents. Natural products are known as the origin of several clinically used anticancer agents, e.g. taxol and vincristine. Among natural products, mangrove-derived fungi are of particular scientific interest evidenced by the increasing rate of publications on cytotoxic secondary metabolites reported. Hence, this literature review aims to provide comprehensive information on cytotoxic secondary metabolites isolated from mangrove-derived fungi, which might contribute to the search for anticancer leads from natural resources. Data were collected from original research articles published on scientific-based sources such as Google Scholar, PubMed, Taylor and Francis, Elsevier, and MDPI, in the range of 2011-2022. Fifty-four cytotoxic secondary metabolites with IC50 values below 10 µM were described herein, which were classified in to 8 groups of metabolites. These compounds were reported from 16 genera of mangrove-associated fungi. Among them, Aspergillus and Penicillium were the most frequent producers of cytotoxic metabolites, suggesting their enormous potential as a source of pharmacophores for anticancer candidates.

Abstract

Marine fungi have demonstrated the ability to produce promising new bioactive compounds. This study aims to isolate fungi from the marine sediments collected from Amed and Tulamben Beaches, Bali, Indonesia and investigate the bioactivity of the fungal extracts. Following fungal isolation, pure isolates were obtained and fermented on rice media containing salt and without salt. Next, secondary metabolites were extracted with ethyl acetate, then separated by liquid-liquid extraction using methanol containing 10% water and n-hexane. The resulting MeOH extracts were analyzed for their phytochemical content and tested for their antimicrobial and antioxidant activities using the disc diffusion and 2,2-diphenyl-1-picrylhydrazyl (DPPH) method, respectively. In total, three fungal isolates were obtained. Molecular identification from the Internal Transcribed Spacer (ITS) region of the isolates showed the closest relationship to Aspergillus sp., Aspergillus tamarii, and Trichoderma sp. Phytochemical analysis showed all fungal extracts contained alkaloids and polyphenols. Moreover, extract from Trichoderma sp. SED-TU (1) (NS) inhibited Staphylococcus aureus, Staphylococcus epidermidis, and Streptococcus mutans with inhibition zone diameters of 4.69±0.16; 3.51±0.01, and 3.49±0.25 mm, respectively. Extract from Aspergillus tamarii RM-S-SED-AM (S) inhibited Candida albicans with an inhibition zone of 7.04±0.22 mm and also had strong antioxidant activity with an IC50 value of 62.00±0.35 µg/mL. This study indicates that fungal isolates from marine sediments have great potential as a source of bioactive natural products.
