Anticancer Activity of Aaptos suberitoides on Glioblastoma Multiforme Cell Line.

ABSTRACT

OBJECTIVE: Glioblastoma Multiforme (GBM) poses a significant challenge due to its high aggressiveness and unfavorable prognosis, with existing treatments demonstrating limited efficacy in prolonging survival rates. This study aimed to assess the anticancer properties of Aaptos suberitoides extracts and fraction on the U87 cell line, serving as a representative model for GBM. METHODS: U87 cells were treated with ethanol extracts derived from Aaptos suberitoides, specifically two extracts (OAA-1 and OAA-2) and one ethyl acetate fraction (EA) isolated from specimens collected on Pramuka Island and Tinjil Island. The evaluation encompased microscopic observation and MTT assay to determine the IC50. Subsequently, antiproliferative effects were investigated through apoptosis and cell cycle assays. RESULTS: The extract demonstrated cytotoxic activity against U87 cells, with OAA-1 and OAA-2 exhibiting IC50 values of 35.78 µg/mL and 25.38 µg/mL, respectively. OAA-1 notably induced apoptosis at 50 µg/mL and induced cell cycle arrest. On other hand, OAA-2, while also inducing apoptosis significantly, had a lesser impact on cell cycle arrest. In contrast, EA induced significant apoptosis at a concentration of 100 µg/mL. CONCLUSION: The ethanol extracts and the ethyl acetate fraction of Aaptos suberitoides emerged as a promising candidate for Glioblastoma Multiforme cancer therapy, showing potential in inhibiting cell proliferation and inducing apoptosis.
