Fms-like tyrosine kinase 3 (FLT3) has been considered as a potential drug target for the treatment of acute myeloid leukemia (AML), because of its high and aberrant expression in AML patients, especially the patients with FLT3-ITD mutation. Initiating from a hit compound (IC50: 500 nM against FLT3-ITD), a series of compounds were designed and synthesized based on benzo[d]oxazole-2-amine scaffold to discover new potent FLT3-ITD inhibitors. During the medicinal chemistry works, flexible molecular docking was used to provide design rationale and study the binding modes of the target compounds. Through the mixed SAR exploration based on the enzymatic and cellular activities, compound T24 was identified with potent FLT3-ITD inhibitory (IC50: 0.41 nM) and anti-proliferative (IC50: 0.037 μM against MV4-11 cells) activities. And the binding mode of T24 with “DFG-in” FLT3 was simulated by a 20-ns molecular dynamics run, providing some insights into further medicinal chemistry efforts toward novel FLT3 inhibitors in AML therapy.

A pharmacophore model for butyrylcholinesterase (BChE) inhibitors was applied to a human cannabinoid subtype 2 receptor (hCB2R) agonist and verified it as a first-generation lead for respective dual-acting compounds. The design, synthesis, and pharmacological evaluation of various derivatives led to the identification of aminobenzimidazoles as second-generation leads with micro- or sub-micromolar activities at both targets and excellent selectivity over hCB1and AChE, respectively. Computational studies of the first- and second-generation lead structures by applying molecular dynamics (MD) on the active hCB2R model, along with docking and MD on hBChE, has enabled an explanation of their binding profiles at the protein levels and opened the way for further optimization. Dual-acting compounds with “balanced” affinities and excellent selectivities could be obtained that represent leads for treatment of both cognitive and pathophysiological impairment occurring in neurodegenerative disorders.
