Phytochemical analysis and anticancer activity of the Pithecellobium dulce seed extract in colorectal cancer cells

Colorectal cancer remains a challenging medical issue worldwide, and utilizing natural products and plants to produce novel, effective and safe therapies against this disease is continuously a sought-after strategy. Fruit and leaf extracts of Pithecellobium dulce (P. dulce) showed potential anticancer properties as they induced apoptosis of breast cancer and Dalton's lymphoma ascites cells. Thus, the main objective of the current study is to determine whether the seed extract of P. dulce will affect apoptosis, cell cycle, migration, and inflammation of LoVo colorectal cancer cells. The high-resolution liquid chromatography-mass spectrometry was used to determine the chemical composition of the P. dulce seed extract, which revealed the presence of 35 phytochemicals. The findings of this study indicated a significant cytotoxic effect of seeds of this plant in colorectal cancer characterized by induction of apoptosis, cell cycle arrest, and reduction of migration. In addition, the seed extract suppressed several genes that are essential for cancer progression such as MMP2, MMP9, and IL-8, and, on the other hand, upregulated pro-apoptotic genes such as BAX and P53. This study has established P. dulce as a potential and valuable source for providing future therapies against colorectal cancer and other cancers.
