A series of monocyclic and bicyclic amino acids have been synthesised and incorporated into thrombin inhibitors based on CGH728, an analogue of the Mitsubishi compound MD805. Benzthiazolylalanine (Bta) was found to be a good non-polar substitute for arginine at the P1 position, yielding compounds with low nanomolar potency and good selectivity for thrombin.

Optimisation of the P2 pharmacophore in a series of thrombin inhibitors: Ion-dipole interactions with lysine 60G
The optimisation of the P2 pharmacophore in a series of thrombin inhibitors is described. The interaction of a number of piperidine P2 functionalities with lysine 60G of thrombin is explored with reference to the crystal structure of inhibitor enzyme complexes. A primary ion-dipole interaction between the terminal P2 side chain group and lysine 60G is evoked to explain the SAR in this series.
