Acute myeloid leukemia (AML) is the most prevalent kind of acute leukemia in adults. Despite the availability of new targeted therapies, AML remains connected with a poor prognosis and decreased rate of survival. Tubeimoside I (TBMS1), a critical compound extracted from Bolbostemma paniculatum, has demonstrated potential anticancer effects in lung and colorectal cancers. Nevertheless, the TBMS1 anticancer pathway against AML is still elusive. This study aimed to explore the potential role of TBMS1 in anti-AML and its molecular mechanism. In vitro, TBMS1 treatment suppressed AML cells proliferation, induced apoptosis, and mitochondrial damage, and elevated ROS levels. Network pharmacological analysis suggested, and subsequent studies confirmed, that TBMS1 induced mitophagy in AML cells by modulating the PINK1/Parkin/Mfnh2 signaling pathway, an effect that was effectively reversed following PINK1 knockdown. In vivo, TBMS1 treatment suppressed the proliferation of AML cells after 21 days, improved the survival rates of nude mice, and showed no evident organ toxicity. These evidences suggest that TBMS1 may have significant therapeutic potential in treating AML.
