New insights into molecular recognition of 1,1-bisphosphonic acids by farnesyl diphosphate synthase.

ABSTRACT: As part of our project pointed at the search of new antiparasitic agents against American trypanosomiasis (Chagas disease) and toxoplasmosis a series of 2-alkylaminoethyl-1-hydroxy-1,1-bisphosphonic acids has been designed, synthesized and biologically evaluated against the etiologic agents of these parasitic diseases, Trypanosoma cruzi and Toxoplasma gondii, respectively, and also towards their target enzymes, T. cruzi and T. gondii farnesyl pyrophosphate synthase (FPPS), respectively. Surprisingly, while most pharmacologically active bisphosphonates have a hydroxyl group at the C-1 position, the additional presence of an amino group at C-3 resulted in decreased activity towards either T. cruzi cells or TcFPPS. Density functional theory calculations justify this unexpected behavior. Altho
