S2286	Cyclosporin A	Cyclosporin A, a non-polar cyclic oligopeptide, is an immunosuppressive agent that binds to cyclophilin and then inhibits calcineurin with IC50 of 7 nM in a cell-free assay. Cyclosporin A is generally given following transplant surgery to prevent rejection and has been used to test its toxic effect on a perfused 3D proximal tubule model.	EMBO Mol Med, 2024, 16(11):2918-2945 Cell Rep, 2024, S2211-1247(23)01591-7 Phytomedicine, 2024, 135:156088
S1322	Dexamethasone	Dexamethasone is a potent synthetic member of the glucocorticoid class of steroid drugs, and an interleukin receptor modulator that has anti-inflammatory and immunosuppressant effects. Dexamethasone induces autophagy and mitophagy. Dexamethasone is tested in hospitalized patients with COVID-19 and is found to have benefits for critically ill patients.	Cell Host Microbe, 2024, S1931-3128(24)00005-2 Nat Commun, 2024, 15(1):7991 Nat Commun, 2024, 15(1):1176
S3124	Dexamethasone Acetate	Dexamethasone (NSC 39471,Dexamethasone 21-acetate) is a potent synthetic member of the glucocorticoid class of steroid drugs, and an interleukin receptor modulator that has anti-inflammatory and immunosuppressant effects.
