Abstract:
In 2020, an estimated 19.3 million new cancer cases and nearly 10 million cancer deaths have occurred worldwide, with colorectal cancer ranking as the third most frequently diagnosed (10.0%). Several attempts have been conducted against cancer, including surgery, radiation, monoclonal antibodies, and chemotherapy. Many people choose natural products as alternatives against cancer. These products will not only help in human life preservation but also work as a source of up-to-date information, leading people away from incorrect information. We discuss the current status, distribution, and future implications of protecting populations with natural products as an alternative against colorectal cancer in Indonesia. Thirty-eight studies were included in this review for data extraction. The distribution of natural products in Indonesia that have potential activity against colorectal cancer cells was predominated by terpenoids, followed by phytosterols, phenolics, alkaloids, and polyisoprenoids. The type of cell line utilized in the cytotoxic activity analysis of natural products was the WiDr cell line, followed by HT-29 cells and HCT-116 cells. This review showed that MTT in vitro assay is a general method used to analyze the cytotoxic activity of a natural product against colorectal cancer cells, followed by other in vitro and in vivo methods. The systematic review provided predictions for several secondary metabolites to be utilized as an alternative treatment against colorectal cancer in Indonesia. It also might be a candidate for a future co-chemotherapy agent in safety, quality, and standardization. In addition, computational methods are being developed to predict the drug-likeness of compounds, thus, drug discovery is already on the road towards electronic research and development.
Insights
Natural products show potential as alternative colorectal cancer treatments in Indonesia. This review highlights terpenoids and other compounds, suggesting future co-chemotherapy applications and aiding drug discovery.
Area of Science:
- Natural Product Chemistry
- Oncology
- Pharmacology
Background:
- Colorectal cancer is a significant global health burden, with millions diagnosed and dying annually.
- Conventional treatments like chemotherapy and radiation have limitations, driving interest in alternative therapies.
- Natural products are increasingly explored for their potential therapeutic benefits in cancer treatment.
Purpose of the Study:
- To review the current status and distribution of natural products in Indonesia with potential activity against colorectal cancer.
- To identify promising natural compounds and assess their potential as alternative or complementary treatments.
- To explore future implications for colorectal cancer management in Indonesia.
Main Methods:
- A systematic review of 38 studies was conducted.
- Data on natural products, their distribution in Indonesia, and cytotoxic activity against colorectal cancer cell lines were extracted.
- Commonly used methods included MTT assays and other in vitro/in vivo analyses.
Main Results:
- Terpenoids were the predominant class of natural products with activity against colorectal cancer cells, followed by phytosterols, phenolics, alkaloids, and polyisoprenoids.
- WiDr, HT-29, and HCT-116 were frequently used cell lines for cytotoxicity testing.
- MTT assays were the most common method for evaluating cytotoxic activity.
Conclusions:
- Several Indonesian natural products, particularly terpenoids, show promise as alternative treatments for colorectal cancer.
- These compounds may serve as future co-chemotherapy agents, requiring further research on safety, quality, and standardization.
- Computational methods are advancing drug discovery for natural product-based therapies.
