Área de la Ciencia:

• Biochemistry
• Molecular Biology
• Pharmacology

Sus antecedentes:

• ABL proto-oncogene 2 (ABL2) is a critical nonreceptor tyrosine kinase involved in cell regulation.
• ABL2 dysregulation is implicated in various cancers, making it a key therapeutic target.
• Existing ABL2 inhibitors face challenges like drug resistance and off-target effects.

Objetivo del estudio:

• To identify novel ABL2 inhibitors from natural compounds using a structure-based virtual screening approach.
• To evaluate the potential of phytoconstituents as alternatives to current tyrosine kinase inhibitors.

Principales métodos:

• Structure-based virtual screening of 11,908 natural compounds from the IMPPAT-2 library using molecular docking.
• Filtering compounds based on physicochemical and pharmacokinetic properties.
• Molecular dynamics simulations, principal component analysis, and free-energy landscape analysis to confirm binding stability and dynamics.

Principales resultados:

• Pachyrrhizin and Lupinisoflavone K demonstrated significant binding affinity to ABL2.
• These compounds exhibited favorable pharmacokinetic profiles.
• Molecular dynamics simulations confirmed stable interactions and hydrogen bonding within the ABL2 binding pocket.

Conclusiones:

• Pachyrrhizin and Lupinisoflavone K are identified as potential ABL2 inhibitors.
• These natural compounds may offer a promising therapeutic strategy for cancers involving ABL2.
• Further in vitro and in vivo studies are recommended for validation.
