Problem statement: Answer the multiple-choice question.
Question: Which compound has a 12.529\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a.) CCN1C(=O)N[C@@H](c2ccc(Br)cc2)C(C(C)=O)=C1C
b.) O=C(CNc1cc(S(=O)(=O)N2CCOCC2)ccc1N1CCCC1)NCc1ccco1
c.) COc1ccc(CCC(C)N2CCC(CO)(Cc3ccccc3)CC2)cc1
Answer: a. CCN1C(=O)N[C@@H](c2ccc(Br)cc2)C(C(C)=O)=C1C
