[{"from": "human", "value": "Design a molecule that meets the criteria outlined in the description. The molecule is an orally bioavailable, synthetic, highly selective adenosine A3 receptor (A3AR) agonist with potential antineoplastic activity. Namodenoson selectively binds to and activates the cell surface-expressed A3AR, deregulating Wnt and NF-kB signal transduction pathways downstream, which may result in apoptosis of A3AR-expressing tumor cells. A3AR, a G protein-coupled receptor, is highly expressed on the cell surfaces of various solid tumor cell types, including hepatocellular carcinoma (HCC) cells, and plays an important role in cellular proliferation."}, {"from": "gpt", "value": "[C][N][C][=Branch1][C][=O][C@@H1][C@H1][Branch2][Ring2][O][C@H1][Branch2][Ring2][=Branch1][C@@H1][Branch1][Ring2][O][Ring1][Branch1][N][C][=N][C][=C][Branch1][N][N][=C][Branch1][#Branch1][N][=C][Ring1][=Branch1][Ring1][=Branch2][Cl][N][C][C][=C][C][=Branch1][=Branch1][=C][C][=C][Ring1][=Branch1][I][O][O]"}]
