The Anti-Leukemic Activities of Campesterol and Α-Tocopherol Against BCL-2 Target through Computational Drug Design Approaches.

Introduction: Heterogeneous Acute Myeloid Leukemia (AML) causes substantial worldwide morbidity and death. AML is characterized by excessive proliferation of immature myeloid cells in the bone marrow and impaired apoptotic regulator expression.
Method: B-Cell Lymphoma 2 (BCL-2), an anti-apoptotic protein overexpressed in AML, promotes leukemic cell survival and chemoresistance. Thus, reducing BCL-2 may treat AML. Anticancer activities are found in Aloe barbadensis Miller (Aloe vera). Thus, this work used molecular modeling to assess Aloe vera bioactive chemicals as BCL-2 inhibitors. Molecular docking simulation showed that all identified Aloe vera phytocompounds have strong BCL-2 binding affinities (-6.7 to -8.7 kcal/mol).
Result: Campesterol and α-tocopherol were identified as promising compounds for BCL-2 inhibitor research based on their drug-likeness, pharmacokinetics, and toxicity profiles. The stability and conformational of the BCL-2-compound complexes showed that the compounds were stable in BCL-2's binding pocket.
Conclusion: Campesterol and α-tocopherol are promising BCL-2 inhibitors that might become effective anti-leukemic therapies with additional in vitro and in vivo research.
