Observation: Failed to modify (bioisosterism) compound Thought: I need to find a different compound to modify Action: Literature Answer Action Input: What are a few other compounds with the same MOA/target as Dasatinib? Observation: Other compounds with the same MOA/target as Dasatinib include imatinib, nilotinib, and bosutinib, which are all tyrosine kinase inhibitors that target BCR-ABL, SRC, and c-KIT (Erik6635 pages 7-7). Additionally, disulfiram, Withaferin A, and parthenolide have been shown to have the same mechanism of action as Dasatinib as proteasome inhibitors in cancer treatment (Iorio1462 pages 6-6). Another compound with the same mechanism of action as Dasa- tinib is AZD0530, which also inhibits dengue virus infection by targeting Fyn kinase (Wispelaere0530 pages 1-1). Thought: I need to get the SMILES string of one of these compounds Action: Molecule search Action Input: imatinib Observation: CC1=C(C=C(C=C1)NC(=O)C2=CC=C(C=C2)CN3CCN(CC3)C)NC4=NC=CC(=N4)C5=CN=CC=C5 Thought: I need to modify this compound to make a novel compound Action: Modify compound Action Input: CC1=C(C=C(C=C1)NC(=O)C2=CC=C(C=C2)CN3CCN(CC3)C)NC4=NC=CC(=N4)C5=CN=CC=C5 Observation: Cc1ccc(NC(=O)c2ccc(CN3CCNCC3)cc2)cc1Nc1nccc(-c2cccnc2)n1 Thought: I need to check if this compound is novel Action: Patent Search Action Input: Cc1ccc(NC(=O)c2ccc(CN3CCNCC3)cc2)cc1Nc1nccc(-c2cccnc2)n1 Observation: Novel Thought: I need to purchase this compound Action: Purchase Action Input: Cc1ccc(NC(=O)c2ccc(CN3CCNCC3)cc2)cc1Nc1nccc(-c2cccnc2)n1 Observation: Purchased from ZINC Thought: I now know the final answer Final Answer: The compound Cc1ccc(NC(=O)c2ccc(CN3CCNCC3)cc2)cc1Nc1nccc(-c2cccnc2)n1 is a novel com- poundwith similar properties to Dasatinib and has been purchased from ZINC. 100
