BACKGROUND Women are under-represented in HIV antiretroviral therapy (ART) studies. Guidelines for selection of ART as initial therapy in patients with HIV-1 infection do not contain sex-specific treatment. We aimed to assess the safety and efficacy of the single tablet integrase inhibitor regimen containing elvitegravir, cobicistat, emtricitabine, and tenofovir disoproxil fumarate compared wit...
BACKGROUND Tests for resistance to HIV drugs are available for clinical use; however, their predictive value has not been fully assessed. OBJECTIVES To determine HIV-1 genotypic predictors of a virologic response to saquinavir-ritonavir therapy in patients in whom at least one previous protease inhibitor-containing regimen had failed and to compare the predictive value of baseline genotype wi...
The serine protease inhibitors diethyl p-nitrophenyl phosphate and phenylmethylsulfonyl fluoride (chemical modifiers of serine residue) and N-acetyl-l-tryptophan ethyl ester (competitive inhibitor of chymotryptic protease) inhibited 1-O-alkyl-2-acetyl-sn-glycero-3-phosphocholine (AGEPC; platelet-activating factor)-induced platelet aggregation and secretion. The inhibition was dependent on the p...
We present the results of classical and QM/MM simulations for inhibition SARS-CoV-2 3CL protease by a hydroxymethylketone inhibitor, PF-00835231. In noncovalent complex carbonyl oxygen atom warhead is placed in oxyanion hole formed residues 143 to 145, while P1–P3 groups are accommodated active site with interactions similar those observed peptide substrate. According alchemical free energy cal...
In order to track the evolution of primary protease inhibitor (PI) resistance mutations in human immunodeficiency virus type 1 (HIV-1) isolates, baseline and follow-up protease sequences were obtained from patients undergoing salvage PI therapy who presented initially with isolates containing a single primary PI resistance mutation. Among 78 patients meeting study selection criteria, baseline p...
Alpha-1-proteinase inhibitor (API) is one of the acute phase proteins. Following an inflammatory stimuli the concentration of API increased up to four folds. Accompanying these quantitative changes, there is qualitative alterations in the structure of carbohydrate moiety (glycosylation). To determine the alterations in the glycosylation of API in inflammation, API was isolated from the sera of...
A newly identified severe acute respiratory syndrome coronavirus (SARS-CoV), is the etiological agent responsible for the outbreak of SARS. The SARS-CoV main protease, which is a 33.8-kDa protease (also called the 3C-like protease), plays a pivotal role in mediating viral replication and transcription functions through extensive proteolytic processing of two replicase polyproteins, pp1a (486 kD...
Clostridium thermocellum encodes a cellulosomal, modular, and thermostable serine protease inhibitor (serpin), PinA. PinA stability but not inhibitory activity is affected by the Fn(III) and Doc(I) domains, and PinA is a broad inhibitor of subtilisin-like proteases and may play a key role in protecting the cellulosome from protease attack.
