User: I have a question about the chemical with SMILES C=CC(=O)N1CCC(c2ccc(C(N)=O)c(-c3ccc(Oc4ccccc4)cc3)n2)CC1.
Assistant: That sounds interesting, how can I help?
User: Please describe this drug.
Assistant: The answer is Orelabrutinib is a small molecule inhibitor of Bruton's tyrosine kinase (BTK; Bruton agammaglobulinemia tyrosine kinase) with potential antineoplastic activity. Upon administration, orelabrutinib binds to and inhibits the activity of BTK. This prevents both the activation of the B-cell antigen receptor (BCR) signaling pathway and BTK-mediated activation of downstream survival pathways, inhibiting the growth of malignant B-cells that overexpress BTK. BTK, a member of the Src-related BTK/Tec family of cytoplasmic tyrosine kinases, is overexpressed or mutated in B-cell malignancies; it plays an important role in the development, activation, signaling, proliferation and survival of B-lymphocytes.
