Raltegravir (MK-0518): an integrase inhibitor for the treatment of HIV-1

20 views | Jun 20 2019

Evering TH et al. indicated it has demonstrated a favorable side-effect profile in treatment-naive and -experienced patients and a subset of heavy treatment-experienced patients have been able a achieve virologic suppression with raltegravir as part of combination therapy despite limited treatment options.

In Vitro antiretroviral properties of S/GSK1349572, a next-generation HIV integrase inhibitor

31 views | May 28 2019

Kobayashi M et al. demonstrated that S/GSK1349572 would be classified as a next-generation drug in the integrase inhibitor class, with a resistance profile markedly different from that of first-generation integrase inhibitors. [Read the Full Post]

Coformulated bictegravir, emtricitabine, and tenofovir alafenamide versus dolutegravir with emtricitabine and tenofovir alafenamide, for initial treatment of HIV-1 infection (GS-US-380-1490): a randomised, double-blind, multicentre, phase 3, non-inferiority trial

33 views | May 08 2019

Sax PE et al. indicated at 48 weeks, virological suppression with the bictegravir regimen was achieved and was non-inferior to the dolutegravir regimen in previously untreated adults. There was no emergent resistance to either regimen. The fixed-dose combination of bictegravir, emtricitabine, and tenofovir alafenamide was safe and well tolerated compared with the dolutegravir regimen. [Read the Full Post]

Susceptibility of porcine endogenous retrovirus to anti-retroviral inhibitors

328 views | Apr 09 2018

Argaw T et al. indicated that some of the licensed anti-retroviral drugs may be useful for controlling PERV infection. However, the efficacy at nanomolar concentrations put forward integrase inhibitors as a drug that has the potential to be useful in the event that xenotransplantation recipients have evidence of PERV transmission and replication.

Corona A et al. provided new structural information to modulate IN and RNase H inhibitory activities for development of dual-acting anti-HIV agents. [Read the Full Post]

Cryo-EM reveals a novel octameric integrase structure for betaretroviral intasome function

Ballandras-Colas A et al. revealed a novel octameric integrase structure for betaretroviral intasome function. [Read the Full Post]

Selectivity for strand-transfer over 3'-processing and susceptibility to clinical resistance of HIV-1 integrase inhibitors are driven by key enzyme-DNA interactions in the active site

822 views | May 13 2017

Métifiot M et al. indicated that the conserved residue Q146 in the flexible loop of HIV-1 integrase is critical for productive viral DNA binding through specific contacts with the virus DNA ends in the 3'-processing and ST reactions. [Read the Full Post]

CD4+ T cell–dependent and –independent cytokine-chemokine network changes in the immune responses of HIV-infected individuals

2190 views | Mar 20 2017

Arnold KB et al identified a critical deficiency in NK cell responses of HIV-infected individuals, independent of CD4(+) T cell depletion, which directs secreted profiles. Our findings illustrate a broad approach for identifying key disease-associated nodes in a multicellular, multivariate signaling network. [Read the Full Post]

Raltegravir is an antiretroviral drug produced by Merck and Co

Epigenetic marks play a major role in the control of cell fate during mammalian development. Among these, the most studied so far is lysine acetylation, a posttranslational modification of histones which inactivates the positive Raltegravir charge of lysines. [Read the Full Post]
