Structural Feature Identification of Amidinophenylurea Derivatives for Factor VIIa Inhibition

Introduction Factor VIIa along with tissue factor starts whole coagulation process, so factor VIIa is acting as attractive target for anticoagulant drug design. The inhibition of factor VIIa can result in inhibition of coagulation in the early stages. The factor VIIa inhibitors can act more potent antithrombotic than factor Xa inhibitors. Variety of factor VIIa inhibitors are reported by the various researchers. It is necessary to indentify the structural requirements which are required for factor VIIa inhibition, which can be achieved by the QSAR and pharmacophore identification studies. The QSAR studies correlate the structural properties with the biological activity which gives idea about the significant properties and non significant properties for desired pharmacological activity. The pharmacophore is nothing but the molecular framework which is having the desired features which are essential for activity. Current manuscript deals with the 3D QSAR by PLS method and pharmacophore identification studies on 28 reported factor VIIa inhibitors. The QSAR model and pharmacophoric hypothesis can be utilised for designing of more potent factor VIIa inhibitors.
