Beschreibung
In November 2013, the European Medicines Agency (EMA) approved elvitegravir (also known as GS 9137 and JTK 303) as a single agent to be used as part of an antiviral regimen that includes a ritonavir-boosted protease inhibitor for the treatment of HIV-1 in adults without mutations indicative of elvitegravir resistance. Elvitegravir is the second of three marketed HIV integrase strand transfer inhibitors (INSTIs) including raltegravir and dolutegravir (this volume of ARMC). Elvitegravir was discovered by modification of a literature naphthyridine HIV integrase inhibitor in which the naphthyridine core served as a bioisostere for the diketo acid moiety in an original series. Serendipitously, a 4-quinolone-3-carboxylic acid precursor en route to the desired bioisosteric glyoxylic acid demonstrated modest integrase inhibition (IC₅₀=1600 nM). Further derivatization led to elvitegravir with enhanced inhibition of integrase strand transfer (IC₅₀=7.2 nM) and significant antiviral activity (EC₅₀=0.9 nM). Elvitegravir was prepared in seven synthetic steps from 2,4-difluoro-5-iodobenzoic acid. The corresponding acid chloride was coupled to ethyl 3-(dimethylamino) acrylate and further substituted with S-valinol. Base promoted cyclization afforded the quinolone which was protected as silyl ether. Negishi coupling installed the 2-fluoro-3-chlorobenzyl moiety. Subsequent hydrolysis and methoxylation afforded elvitegravir.

Verwenden
A novel inhibitor of human immunodeficiency virus type 1 integrase.
Verwenden
Elvitegravir is a quinolone antibiotic that inhibits the integrase of HIV-1 (IC50 = 7.2 nM). It blocks the integration of HIV-1 cDNA through the inhibition of DNA strand transfer. Elvitegravir is used in combination with a pharmacoenhancer and nucleoside/nucleotide reverse transcriptase inhibitors to block HIV-1 replication in vivo.[Cayman Chemical]
Verwenden
Elvitegravir (EVG, JTK-303/GS-9137) is an HIV integrase inhibitor for HIV-1 IIIB, HIV-2 EHO and HIV-2 ROD with IC50 of 0.7 nM, 2.8 nM and 1.4 nM, respectively.
Definition
ChEBI: A quinolinemonocarboxylic acid that is 7-methoxy-4-oxo-1,4-dihydroquinoline-3-carboxylic acid substited at position 1 by a 1-hydroxy-3-methylbutan-2-yl group and at position 6 by a 3-chloro-2-fluorobenzyl group (the S-enantiomer). It is us d in combination therapy for the treatment of HIV-1 infection.

Synthese
Commercial 2,4-dimethoxy-5-bromo benzoic acid (61) was reacted with 0.5 equiv of butylethylmagnesium to generate the dimagnesium salt in THF, which was then lithiated at 20 to give the aryl lithium species. The aryl lithium species was then reacted with the 2-fluoro-3-chloro benzaldehyde (62) to give alcohol 63. Treatment with triethylsilane in TFA resulted in removal of the hydroxyl functionality to provide benzoic acid 64. This acid was then reacted with carbonyldiimidazole and subsequently magnesium malonate 65 to give ketoester 66 after workup. Next, condensation with DMF¨CDMA converted ketoester 66 to the vinylogous amide 67, and this material was immediately subjected to an addition¨Celimination reaction involving (S)-valinol (68) in toluene at ambient temperature to provide intermediate 69. Warming the resulting intermediate 69 in the presence of N,Obistrimethylsilyl acetamide (BSA) and potassium chloride in DMF furnished the ring-closed quinolone 70. The ester 70 was saponified with potassium hydroxide in aqueous isopropanol and then acidified and crystallized with the use of seed crystals. Upon cooling, the crystalline product elvitegravir (IX) was collected by filtration.
