The present invention provides a compound of formula I, a tautomer thereof, or a pharmaceutically acceptable salt or N-oxide thereof for use in the treatment or prevention of a cardiovascular disease or of an inflammatory disease or condition:
Compounds are described which have efflux pump inhibitor activity. Also described are methods of using such efflux pump inhibitor compounds and pharmaceutical compositions which include such compounds.
1 (HIV-1) and represents a remaining target for antiretroviral drugs. Here, we describe the modification of a quinolone antibiotic to produce the novel integrase inhibitor JTK-303 (GS 9137) that blocks strand transfer by the viral enzyme. It shares the core structure of quinolone antibiotics, exhibits an IC50 of 7.2 nM in the strand transfer assay, and shows an EC50 of 0.9 nM in an acute HIV-1 infection
The labelling reagent 2-[18F]fluoroethylazide was used in a traceless Staudinger ligation. This reaction was employed to obtain the GABAA receptor binding 6-benzyl-4-oxo-1,4-dihydro-quinoline-3-carboxylic acid (2-[18F]fluoroethyl) amide. The radiotracer was prepared with a non-decay corrected radiochemical yield of 7%, a radiochemical purity >95% and a specific radioactivity of 0.9 GBq/μmol. The compound
Human immunodeficiency virus type 1 (HIV-1) integrase is a crucial target for antiretroviral drugs, and several keto-enol acid class (often referred to as diketo acid class) inhibitors have clinically exhibited marked antiretroviral activity. Here, we show the synthesis and the detailed structure-activity relationship of the quinolone carboxylic acids as a novel monoketo acid class of integrase inhibitors. 6-(3-Chloro-2-fluorobenzyl)- 1-((2,S)-1-hydroxy-3,3-dimethylbutan-2-yl)-7-methoxy-4-oxo- 1,4-dihydroquinoline-3-carboxylic acid 51, which showed an IC50 of 5.8 nM in the strand transfer assay and an ED50 of 0.6 nM in the antiviral assay, and 6-(3-chloro-2-fluorobenzyl)-1-((2S)-1-hydroxy-3-methylbutan-2-yl)-7-methoxy-4-oxo-4-dihydroquinoline-3-carboxylic acid 49, which had an IC50 of 7.2 nM and an ED50 of 0.9 nM, were the most potent compounds in this class. The monoketo acid 49 was much more potent at inhibiting integrase-catalyzed strand transfer processes than 3'-processing reactions, as is the case with the keto-enol acids. Elvitegravir 49 was chosen as a candidate for further studies and is currently in phase 3 clinical trials.
