Bisphosphonates derived from fatty acids are potent inhibitors of Trypanosoma cruzi farnesyl pyrophosphate synthase
摘要:
Studies on the mode of action of a series of bisphosphonates derived from fatty acids, which had previously proved to be potent inhibitors against Trypanosoma cruzi proliferation in in vitro assays, have been performed. Some of these drugs proved to be potent inhibitors against the intracellular form of the parasite, exhibiting IC50 values at the low micromolar level. As bisphosphonates are FDA clinically approved for treatment of bone resorption disorders, their potential innocuousness makes them good candidates to control tropical diseases.

Condensation of aldehydes with diethyl phosphite followed by sulfonylation of the alpha-hydroxy group formed with methanesulfonyl chloride and subsequent substitution by another molecule of diethylphosphite provides corresponding alkylidenebisphosphonates in one-pot procedure with good yield.
