Second Generation Tetrahydroquinoline-Based Protein Farnesyltransferase Inhibitors as Antimalarials
摘要:
Substituted tetrahydroquinolines (THQs) have been previously identified as inhibitors of mammalian protein farnesyltransferase (PFT). Previously we showed that blocking PFT in the malaria parasite led to cell death and that THQ-based inhibitors are the most potent among several structural classes of PFT inhibitors (PFTIs). We have prepared 266 THQ-based PFTIs and discovered several compounds that inhibit the malarial enzyme in the sub- to low-nanomolar range and that block the growth of the parasite (P. falciparum) in the lownanomolar ran-e. This body of structure- activity data can be rationalized in most cases by consideration of the X-ray structure of one of the THQs bound to mammalian PFT together with a homology structural model of the malarial enzyme. The results of this study provide the basis for selection of antimalarial PFTIs for further evaluation in preclinical drug discovery assays.

This invention provides methods and pharmaceutical compositions that can treat neuroinflammatory disease by reducing the production of pyrophosphate intermediates produced during the biosynthesis of isoprenoids. The pyrophosphate compounds being inhibited are normally produced through the mevalonate and non-mevalonate pathways of the host vertebrate organisms and their symbiotic and pathogenic microorganisms. The methods involve administering to a patient an inhibitor of the mevalonate-dependent pathway, an inhibitor of the non-mevalonate pathway, or combination of such inhibitors.
