Human polyomavirus BK (BKPyV) is the etiol. agent of polyomavirus-associated nephropathy, a leading cause of kidney transplant dysfunction. Because of the lack of antiviral therapies, immunosuppression minimization is the recommended treatment. This strategy offers suboptimal outcomes and entails a significant risk of rejection. Our aim was to evaluate the effect of different immunosuppressive drugs (leflunomide, tacrolimus, mycophenolic acid, sirolimus, and everolimus) and their combinations in an in vitro model of BKPyV infection. Human renal tubular epithelial cells were infected with BKPyV and treated with leflunomide, tacrolimus, mycophenolic acid, sirolimus, and everolimus, administered alone or in some combination thereof. Viral replication was assessed every 24 h (up to 72 h) by BKPyV-specific quant. real-time polymerized chain reaction for the VIRAL PROTEIN 1 sequence in cell supernatants and by western blot anal. targeting the viral protein 1 and the glyceraldehyde 3-phosphate dehydrogenase on total protein lysates. Results were described as viral copies/mL and compared between treatments at any prespecified time point of the study. The highest inhibitory effects were observed using leflunomide or everolimus plus mycophenolic acid (mean BKPyV replication log reduction 0.28). The antiviral effect of everolimus persisted when it was used in combination with tacrolimus (mean BKPyV replication log reduction 0.27). Our experience confirms that everolimus has anti-BKPyV properties and prompts future research to investigate possible mechanisms of action. It also provides a rational basis for targeted clin. trials evaluating alternative immunosuppressive modification strategies. In the experiment, the researchers used many compounds, for example, (E)-6-(4-Hydroxy-6-methoxy-7-methyl-3-oxo-1,3-dihydroisobenzofuran-5-yl)-4-methylhex-4-enoic acid (cas: 24280-93-1Category: benzofurans).
(E)-6-(4-Hydroxy-6-methoxy-7-methyl-3-oxo-1,3-dihydroisobenzofuran-5-yl)-4-methylhex-4-enoic acid (cas: 24280-93-1) belongs to benzofurans derivatives. Benzofurans are compounds with a planar structure having 10 pi electrons that include the lone pair on oxygen atom, which makes it more susceptible to electrophilic attack. Benzofurans have also made significant and distinctive contributions to biology. They exhibit several biological activities that range from antioxidant, antitubercular, antiplasmodial, insecticidal.Category: benzofurans
