To compare the effects on CD4 counts and safety of MK-639 (indinavir, IDV) and AZT administered concomitantly to MK-639 alone and AZT alone in HIV-1 seropositive patients.
Patients are randomized to 1 of 3 groups for 12 months of treatment. Group 1 receives MK-639 plus AZT. Group 2 receives MK-639 alone. Group 3 receives AZT alone. Safety and tolerability are assessed by the incidence of clinical and laboratory adverse experiences. Blood and urine samples are collected for safety assessment and to determine CD4 cell counts and serum viral RNA levels. If therapy with MK-639 alone or with AZT is found to be generally safe and clinically efficacious, patients who have completed the study will have the opportunity to continue in an extension study protocol on a treatment regimen including MK-639.

To determine the clinical efficacy of indinavir sulfate or placebo in combination with zidovudine ( AZT ) and lamivudine ( 3TC ) in AIDS patients. Protease inhibitors such as indinavir su...
The purpose of this study is to see whether it is better to take delavirdine (DLV) plus indinavir (IDV) plus zidovudine (ZDV) twice a day or three times a day.
To demonstrate that the antiviral activity and safety/tolerability of a test regimen of indinavir is equivalent to that of a control regimen of indinavir when each is coadministered with z...
The purpose of this study is to see if it is safe and effective to give indinavir sulfate plus stavudine to HIV-infected patients who have already been treated with zidovudine.
The purpose of this study is to compare the safety and effectiveness of three anti-HIV drug combinations. The three combinations are: (1) efavirenz (DMP 266) plus indinavir; (2) DMP 266 pl...
The crystal structure of indinavir sulfate, a pharmaceutical administered as an ethanol solvate, is presented, revealing a unique channel/ionic solvate structure to be characteristic of the compound. ...
Nowadays, zidovudine, efavirenz, lopinavir and ritonavir are important components of the second-line antiretroviral therapeutic regimen of National Free Antiretroviral Treatment Program in China. The ...
The aim of this study was to use the liquid chromatography/tandem mass spectrometry (LC-MS/MS) method to quantitate levels of three urinary glycosaminoglycans (GAGs; dermatan sulfate [DS], heparan sul...
Growth and development of an embryo or fetus during human pregnancy mainly depend on intact hormone biosynthesis and metabolism in maternal amniotic fluid (AF). We investigated the hormonal milieu in ...
Derivatives of chondroitin which have a sulfate moiety esterified to the galactosamine moiety of chondroitin. Chondroitin sulfate A, or chondroitin 4-sulfate, and chondroitin sulfate C, or chondroitin 6-sulfate, have the sulfate esterified in the 4- and 6-positions, respectively. Chondroitin sulfate B (beta heparin; DERMATAN SULFATE) is a misnomer and this compound is not a true chondroitin sulfate.
An enzyme that catalyzes the activation of sulfate ions by ATP to form adenosine-5'-phosphosulfate and pyrophosphate. This reaction constitutes the first enzymatic step in sulfate utilization following the uptake of sulfate. EC 22.214.171.124.
An arylsulfatase that catalyzes the hydrolysis of the 4-sulfate groups of the N-acetyl-D-galactosamine 4-sulfate units of chondroitin sulfate and dermatan sulfate. A deficiency of this enzyme is responsible for the inherited lysosomal disease, Maroteaux-Lamy syndrome (MUCOPOLYSACCHARIDOSIS VI). EC 126.96.36.199.
An enzyme that specifically cleaves the ester sulfate of iduronic acid. Its deficiency has been demonstrated in Hunter's syndrome, which is characterized by an excess of dermatan sulfate and heparan sulfate. EC 188.8.131.52.
A potent and specific HIV protease inhibitor that appears to have good oral bioavailability.
