WebMar 7, 2024 · It was demonstrated that pemetrexed inhibited Kaposi’s sarcoma-associated herpesvirus, reversibly inhibiting TS or DHFR proteins by interfering with DNA replication . Pteridine derivatives as methotrexate, pralatrexate, and triamterene have shown diverse biological activities and can apply to several other diseases such as diabetes ... WebA dihydrofolate reductase inhibitor (DHFR inhibitor) is a molecule that inhibits the function of dihydrofolate reductase, and is a type of antifolate. Since folate is needed by rapidly dividing cells to make thymine, this effect may be used to therapeutic advantage.
Dihydrofolate reductase as a therapeutic target - PubMed
WebSep 8, 2009 · The physiological function of dihydrofolate reductase (DHFR) is the reduction of 7,8-dihydrofolate (7,8-DHF) produced in the reaction of thymidylate synthase and possibly by autooxidation of tetrahydrofolate.It also may aid in the regeneration of tetrahydrobiopterin in endothelial cells needed for coupled nitric oxide synthase activity (). ... WebOverexpression of miR-192 inhibited cellular proliferation by binding DHFR. miR-192 decreased cellular anchoring via the repression of ITGAV, ITGB1, ITGB3, and CD47. Animals in the miR-192-treated group demonstrated a reduction of spinal seeding (P 0.05) and a significant survival benefit (P 0.05). osteria da christian cuneo

WebIn this study, a library of analogues based on a DHFR inhibitor, trimetrexate (TMQ), an FDA-approved drug, was screened and three new analogues that selectively inhibited S. mutans were identified. The most potent inhibitor had a 50% inhibitory concentration (IC50) of 454.0±10.2nM for the biofilm and 8.7±1.9nM for DHFR of S. mutans. WebJun 24, 2024 · Even dihydrofolate reductase (DHFR), a well-characterized and historically important drug target, has not been conclusively validated as an antifungal target. Here, we demonstrate that repression of DHFR inhibits growth of Candida albicans, a major human fungal pathogen. Methotrexate, an antifolate, also inhibits growth but through pH … WebOct 3, 2012 · The best known such target is P. falciparum dihydrofolate reductase (DHFR), which is inhibited by the antimalarials PYR and cycloguanil (CG) .
