Background: The species of genus Macaranga are widely found in Malaysian secondary forests and has been used as an alternative for treating varieties of illness. Studies have shown that the medicinal properties of this genus contain anti-inflammatory, antioxidant, and anti-cancer effects. This study aimed to determine the cytotoxicity of six isolated phytochemicals from Macaranga heynei (M. heynei), Macaranga lowii and Shorea leprosula on HT-29 human colorectal adenocarcinoma cell lines. Results: One out of six isolated phytochemical compounds, identified as “Laevifolin A”, showed a cytotoxicity with an IC50 value of 21.2 µM following 48 h treatment as detected using Sulforhodamine B (SRB) assay. Additionally, no induction of apoptosis and oxidative stress were observed on Laevifolin A treated HT-29 cells as determined using Annexin V-FITC/PI assay and dihydroethidine (HE) staining, respectively. Additionally, no damage to the DNA were observed as measured using the Alkaline Comet assay. Further investigation on menadione-induced oxidative DNA damage showed the genoprotective potential of Laevifolin A on HT-29 cells. Conclusions: In conclusion, this study indicated that only one compound (Laevifolin A) that extracted from M. heynei has the cytotoxicity potential to be developed as an anticancer agent in human colorectal adenocarcinoma. However, besides exhibiting cytotoxic effect, the compound also exhibits genoprotective capability that warrant further investigation. © 2023, The Author(s).
