MedChemExpress adenosine a2a receptor a2ar antagonist sch58261
The design of an inflammatory macrophages-targeted, acid-sensitive PNSH for delivery MTX and its role in promoting <t>A2AR</t> activation on M2 macrophages for arthritis therapy. (A)The structure of acid-sensitive polymer-nanomedicine supramolecular hydrogels, composed of drug-loaded MTX NPs. (B) Schematic illustration of arthritis therapy targeting inflammatory joint network via mPECN NPs-mediated release of MTX. This approach leverages MTX targeting the A2AR and repolarization of macrophages from the pro-inflammatory M1 phenotype to the anti-inflammatory M2 phenotype. Activation of A2AR and macrophage repolarization by mPECN-MTX NPs synergistically enhanced the anti-inflammatory effect of PNSH-mediated nanomedicine in an arthritis rat model.
