Problem statement: Answer the multiple choice question.
Question: Which drug has a -3.895\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
(a) CCc1ccc(NC(=O)CCNS(=O)(=O)c2cccs2)cc1
(b) CSc1ccc(S(=O)(=O)NCCCOC(C)C)cc1
(c) CC(C)=CCN1CCN(Cc2cccn2-c2ncccn2)CC1CCO
(d) CC(=O)Nc1ccc(S(=O)(=O)NCC2CCC(C(=O)NCCCN3CCCC3=O)CC2)cc1
Answer: c. CC(C)=CCN1CCN(Cc2cccn2-c2ncccn2)CC1CCO
