Acute myeloid leukemia (AML) with FLT3 mutations is a malignant blood cancer.
However, current FLT3 inhibitors used in its treatment have significant side effects
and drug resistance problems. Our study aimed to identify relatively safe and
effective FLT3 inhibitors from natural phytocompounds to overcome the limitations
of current therapies. A total of 2792 phytocompounds were collected from 19
medicinal plants and screened virtually against the FLT3 protein active site. Fifteen
top compounds were selected based on docking scores. ADMET analysis and
molecular dynamics (MD) simulation were performed to evaluate pharmacokinetics,
toxicity, and stability. Three compounds — asperglaucide, 17betahydroxywithanolide
K, and withanicandrin — showed strong binding affinities (−9.4,
−10.1, and −10.9 kcal/mol, respectively), which were superior to the synthetic
inhibitors gilteritinib (−9.1 kcal/mol). ADMET analysis confirmed favorable GI
absorption, solubility, and low toxicity, comparable to gilteritinib. The 100-ns MD
simulations (RMSD, RMSF, RG, SASA, hydrogen bonds) showed that asperglaucide
formed the most stable protein-ligand complex. Natural compounds, especially
asperglaucide, have shown promising potential as FLT3 inhibitors for the treatment
of AML. Further in vitro and in vivo studies are needed to verify their therapeutic
efficacy.
