Current treatments against leukemia present several limitations, prompting the search for new therapeutic agents, particularly those derived from natural products. In this context, structural modifications were performed on the triterpene 3&alpha:,24-dihydroxylup-20(29)-en-28-oic acid (T1), isolated from Phoradendron wattii. Among the five derivatives obtained, 3&alpha:,24-dihydroxy-30-oxolup-20(29)-en-28-oic acid (T1c) exhibited the highest activity, with an IC50 value of 12.90 ±: 0.1 µ:M against THP-1 cells. T1c significantly reduced cell viability in both acute lymphoblastic leukemia (CCRF-CEM, REH, JURKAT, and MOLT-4) and acute myeloid leukemia (THP-1) cell lines, inducing apoptosis after 48 h of treatment, while showing minimal cytotoxicity toward normal mononuclear cells (MNCs). In silico molecular docking studies were conducted against three key protein targets: BCL-2 (B-cell lymphoma 2), EGFR (epidermal growth factor receptor, tyrosine kinase domain), and FLT3 (FMS-like tyrosine kinase 3). The lowest binding energies (kcal/mol) observed were as follows: T1&ndash:BCL-2: &minus:10.12, EGFR: &minus:12.75, FLT3: &minus:14.05: T1c&ndash:BCL-2: &minus:10.23, EGFR: &minus:14.50, FLT3: &minus:14.07: T2&ndash:BCL-2: &minus:11.59, EGFR: &minus:15.00, FLT3: &minus:14.03. These findings highlight T1c as a promising candidate in the search for anti-leukemic drugs which deserves further study.
