摘要:

Some 1,2,5-trisubstituted benzimidazole fluorinated derivatives were designed and screened by molecular docking. Five compounds which obtained high scores were selected to synthesize. All the target products were char-acterized by 1H NMR, 13C NMR and high resolution mass spectra(HRMS) and preliminarily screened for inhibitory activity against thrombin, among which three compounds(5a, 5c and 5e) were evaluated in vitro. The results showed that compounds 5a, 5c and 5e exhibited better anticoagulant activity than argatroban. Docking simulations demonstrated that these compounds may act as candidates for further studies on thrombin inhibitors.

The results showed that compounds 5a, 5c and 5e exhibited better anticoagulant activity than argatroban. Docking simulations demonstrated that these compounds may act as candidates for further studies on thrombin inhibitors.
