Supramolecular assembly 1 catalyzes a bimolecular aza-Prins cyclization featuring an unexpected transannular 1,5-hydride transfer. This reaction pathway, which is promoted by constrictive binding within the supramolecular cavity of 1, is kinetically disfavored in the absence of 1, as evidenced by the orthogonal reactivity observed in bulk solution. Mechanistic investigation through kinetic anal...
A series of subporphyrin-based fluorescent probes bearing 1-aza-15-crown-5 or 1-aza-18-crown-6 moieties at the meso axial positions were prepared by Pd-catalyzed Buchwald-Hartwig amination reaction corresponding bromosubporphyrins. Both types aza-crown-ether-incorporated subporphyrins in solution and exhibited cation-dependent absorption fluorescence changes. In titration experiments, opposite ...
Objective To assess the safety of azathioprine (AZA) in Japanese patients with antineutrophil cytoplasmic antibody-associated vasculitis (AAV). Methods We retrospectively enrolled 67 consecutive AAV patients who had initiated AZA treatment from January 2006 to August 2014 at Okayama University Hospital. We evaluated the development of severe adverse events (AEs), AZA discontinuation due to tota...
Background/Aims. We aimed to examine the cost-effectiveness of mycophenolate mofetil (MMF) and azathioprine (AZA) as maintenance therapy for patients with Class III and Class IV lupus nephritis (LN), from a United States (US) perspective. Methods. Using a Markov model, we conducted a cost-utility analysis from a societal perspective over a lifetime horizon. The modeled population comprised pati...
BACKGROUND Human leukocyte antigen (HLA)-identical living-related (LR) kidney transplant recipients often receive the standard regimen of immunosuppression. We wondered whether these patients should be exposed to the side effects of these drugs any longer. Safe tapering of immunosuppression should not result in rejection and high donor-directed T-cell responses. In the present study, we investi...
Prostate cancer is a leading cause of death in males aged fifty and over. Glutathione transferase (GST) activity is depressed in prostate cancer cells. The aim of this study was to assess GST reactivation in LNCaP prostate cancer cells treated with curcumin or 5-azacitidine (5-Aza) which is a known hypomethylation agent. GST activity was determined using monochlorobimane (MCB). Cell viability w...
Purpose: To investigate the in vitro differentiation process of cardiomyocyte-like cells derived from human bone marrow mesenchymal stem cells under the influence of 5-azacytidine (5-aza). Materials and Methods: After purification, human bone marrow mesenchymal stem cells were exposed to 5-aza at a concentration of 5 μmol for 5 weeks to induce cardiomyocyte differentiation. To induce differenti...
Pancreatic adenocarcinoma is a lethal disease because it is inoperable at the time of diagnosis. Therefore, the search for new therapeutic approaches is critical. The abnormal expression of the mitogen-activated protein kinase/extracellular signal-regulated kinase (MEK) pathway and alteration in epigenetic modification (DNA methylation and acetylation of histones) is a common feature in the maj...
