BACKGROUND Combination therapy with infliximab (IFX) and azathioprine (AZA) is significantly more effective for treatment of active Crohn's disease (CD) than IFX monotherapy. However, AZA is associated with an increased risk of lymphoma in patients with inflammatory bowel disease. AIM To evaluate the cost-effectiveness of combination therapy with IFX plus AZA for drug-refractory CD. METHODS...
OBJECTIVE The present study sought to elucidate the genetic basis of thiopurine methyltransferase (TPMT) polymorphism and subsequently to investigate the relationship between mutant TPMT and an adverse response observed in Korean patients with systemic lupus erythematosus (SLE) taking azathioprine (AZA). METHODS The TPMT genotype of 342 patients with SLE was determined by MALDI-TOF mass spect...
BACKGROUND AND AIMS Azathioprine [AZA] is recommended for maintenance of steroid-free remission in inflammatory bowel disease IBD. The aim of this study has been to establish the incidence and severity of AZA-induced pancreatitis, an idiosyncratic and major side effect, and to identify specific risk factors. METHODS We studied 510 IBD patients [338 Crohn's disease, 157 ulcerative colitis, 15 ...
1. When (+/-)-8-aza-d-homo-oestrone 3-methyl ether was added to a culture of Aspergillus ochraceus, the laevo-rotatory enantiomer is reduced to a 17A alcohol. Thus (+/-)-8-aza-d-homo-oestrone 3-methyl ether has been resolved into both its components, the laevo-rotatory enantiomer being obtained by chromic acid oxidation of the alcohol, and the dextro-rotatory enantiomer as residual precursor fr...
The most commonly prescribed medication for autoimmune disorders is Azathioprine (AZA), which negatively affects renal function and tissue structure. aim of this work was to measure the therapeutic impact Zingiber officinale L. extract (ZOE) on improving structure AZA-induced damaged tissue.
 Methods: 70 rats with a weight range 200±10 g an age 95±5 days were chosen experimental study. ani...
Glutathione transferase (GST) A2-2 is the human enzyme displaying the highest catalytic activity with the prodrug azathioprine (Aza). The reaction releases pharmacologically active 6-mercaptopurine by displacing the imidazole moiety from the Aza molecule. The GST-catalyzed reaction is of medical significance, since high rates of Aza activation may lead to adverse side effects in treated patient...
Polypharmacology (the ability of a drug to affect more than one molecular target) is considered a basic property of many therapeutic small molecules. Herein, we used a chemical genomics approach to systematically analyze polypharmacology by integrating several analytical tools, including the LINCS (Library of Integrated Cellular Signatures), STITCH (Search Tool for Interactions of Chemicals), a...
Systemic acquired resistance (SAR) is a form of inducible disease resistance that depends on salicylic acid and its upstream regulator ENHANCED DISEASE SUSCEPTIBILITY1 (EDS1). Although local Arabidopsis thaliana defence responses activated by the Pseudomonas syringae effector protein AvrRpm1 are intact in eds1 mutant plants, SAR signal generation is abolished. Here, the SAR-specific phenotype o...
Epigenetic alterations are a hallmark of cancer that govern the silencing of genes. Up to now, 5-azacytidine (5-aza-CR, Vidaza) and 5-aza-2'-deoxycytidine (5-aza-dC, Dacogen) are the only clinically approved DNA methyltransferase inhibitors (DNMTi). Current effort tries to exploit DNMTi application beyond acute leukemia or myelodysplastic syndrome, especially to solid tumors. Although both drug...
Mismatch-repair (MMR)-deficient cells show increased in vitro tolerance to thiopurines because they escape apoptosis resulting from MMR-dependent signaling of drug-induced DNA damage. Prolonged treatment with immunosuppressants including azathioprine (Aza), a thiopurine prodrug, has been suggested as a risk factor for the development of late onset leukemias/lymphomas displaying a microsatellite...
