Task: Answer the multiple choice question.
Question: Which compound has a -72.017% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
[a] O=C(NN1C(=O)/C(=C/c2cc([N+](=O)[O-])ccc2O)SC1=S)c1ccccc1O
[b] COc1ccc(Br)cc1S(=O)(=O)N1CCOCC1
[c] CCN1CCN(c2c(Cl)cccc2NC(=O)c2ccc([N+](=O)[O-])cc2)CC1
[d] Nc1cc(C(Cl)=C(Cl)Cl)c(S(N)(=O)=O)cc1S(N)(=O)=O
[e] COc1ccc(N2CCN(c3ccc(C(=O)O)cc3[N+](=O)[O-])CC2)cc1
Answer: c. CCN1CCN(c2c(Cl)cccc2NC(=O)c2ccc([N+](=O)[O-])cc2)CC1
