[{"from": "human", "value": "Generate a molecule based on the given description. The molecule is the mesylate salt of puquitinib, an orally available selective inhibitor of the delta form of phosphatidylinositol 3-kinase (PI3-kinase subunit delta; PI3K-delta; PI3Kdelta), with potential antineoplastic activity. Upon oral administration, puquitinib selectively binds to the ATP-binding pocket of PI3K-delta and prevents the activation of the PI3K/AKT signaling pathway. This decreases proliferation of and induces cell death in PI3K-delta over-expressing tumor cells. PI3K-delta also plays a key role in the B-cell receptor (BCR) signaling pathway and the proliferation of certain hematologic cancer cells. The targeted inhibition of PI3K-delta is designed to preserve PI3K signaling in normal, non-neoplastic cells, thereby minimizing serious side effects."}, {"from": "gpt", "value": "[C][S][=Branch1][C][=O][=Branch1][C][=O][O].[C][S][=Branch1][C][=O][=Branch1][C][=O][O].[C][C][C][Ring1][Ring1][N][C][=N][C][=Branch1][O][=N][C][=C][Ring1][=Branch1][N][C][=N][Ring1][Branch1][N][C][=C][C][=C][Branch1][Branch1][C][=C][Ring1][=Branch1][N][=C][C][=C][Ring1][Branch2]"}]
