S5358 Regadenoson Regadenoson (CVT-3146, Lexiscan) is a selective A2A adenosine receptor agonist with coronary vasodilating activity.
S0498 Namodenoson (CF-102) Namodenoson (CF-102, 2-Cl-IB-MECA) is an orally bioavailable and selective agonist of the A3 adenosine receptor (A3AR) with Ki of 0.33 nM. This compound exerts an anti-NASH effect mediated via the de-regulation of the PI3K/NF-κB/Wnt/β-catenin signalling pathway.
E4032 5'-Deoxy-5'-(methylthio)adenosine 5'-Deoxy-5'-(methylthio)adenosine (Methylthioadenosine, MTA) is a naturally occurring sulfur-containing nucleoside produced by the decarboxylation of S-adenosylmethionine. This nucleoside is a potent agonist of adenosine receptors with Ki of 0.15, 1.13, 13.9, and 0.68 μM for A1, A2A, A2B, and A3, respectively.
E2985 Capadenoson Capadenoson (BAY 68-4986) is an orally bioavailable, non-nucleoside partial adenosine A1 receptor agonist that exhibits an anti-ischemic effect.
E4450 N6-Cyclopentyladenosine N6-Cyclopentyladenosine is an adenosine derivative and a potent adenosine receptor agonist with Ki values of 2.3 nM, 790 nM and 43 nM for human A1, A2A and A3 receptors, respectively. It acts as an anticonvulsant and might exhibit protective actions against (AMPH)-induced seizures.
S5678 trans-Zeatin-riboside Zeatin Riboside is the most active and ubiquitous form of the naturally occurring cytokinins that promote cell division, stimulate shoot proliferation, inhibit root formation, slow the aging process, and activate gene expression and metabolic activity. Zeatin riboside has an immunomodulatory effect by agonizing the mammalian adenosine A2A receptor.
E4626 BAY 60-6583 BAY 60-6583 is a non-purine and selective agonist of adenosine A2breceptor, with an EC50 of 3-10 nM for human A2breceptors and >10 μM for A1 and A2areceptors. It binds to adenosine A2breceptor in mice, rabbits, and dogs with Ki of 750 nM, 340 nM, and 330 nM, respectively. It also enhances the antitumor activity of chimeric antigen receptor-modified T cells.
S6347 5'-N-Ethylcarboxamidoadenosine (NECA) 5'-N-Ethylcarboxamidoadenosine (NECA, 5'-(N-Ethylcarboxamido)adenosine, Adenosine-5'N-ethylcarboxamide, 5'-Ethylcarboxamidoadenosine) is a stable, nonselective adenosine receptor agonist. It acts via multiple mechanisms including: reducing diabetes-induced oxidative stress, inhibiting gene expression of IL-18, TNF-α and ICAM-1 (intercellular adhesion molecule 1 (CD54)), and blocking activation of the JNK-MAPK pathway.
E6040New Imiquimod maleate Imiquimod maleate (R 837 maleate) is a small-molecule salt derivative of maleic acid, isolated from the Imiquimod free base and is an immune response modifier, a potent and selective agonist of toll like receptor 7 (TLR7), an antagonist of adenosine A₂A receptor with a Ki of 2.16 μM, and an inhibitor of adenylyl cyclase activity, inducing antiviral proteins like cystatin A. It exhibits strong antitumoral and antiviral efficacy, making it effective for conditions such as COVID 19, HPV warts, molluscum contagiosum, actinic keratosis, basal and squamous cell carcinoma, Bowen's disease, and vulvar intraepithelial neoplasia.
E6039 Imiquimod hydrochloride Imiquimod hydrochloride (R 837 hydrochloride) is a small-molecule immune response modifier, a potent and selective agonist of toll like receptor 7 (TLR7), an antagonist of adenosine A₂A receptor with a Ki of 2.16 μM, and an inhibitor of adenylyl cyclase activity, inducing antiviral proteins like cystatin A. It exhibits strong antitumoural and antiviral efficacy, making it effective for conditions such as COVID 19, HPV warts, molluscum contagiosum, actinic keratosis, basal and squamous cell carcinoma, Bowen's disease, and vulvar intraepithelial neoplasia.
