Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a -71.770% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
[a] Cc1nc(NC(=O)c2ccccc2)sc1-c1csc(NCCc2ccccc2)n1
[b] CCOc1ccc(N2CC(C(=O)N3CCN(c4ccccc4)CC3)CC2=O)cc1
[c] O=[N+]([O-])c1ccc(N2CCN(Cc3cccc([N+](=O)[O-])c3)CC2)cc1
[d] CN(C)c1ccc(/C=C(/NC(=O)c2ccccc2)C(=O)N/N=C/c2ccc([N+](=O)[O-])c(O)c2)cc1
[e] Cc1nc2sc(-c3ccccc3)cc2c(=O)n1N
Answer: c. O=[N+]([O-])c1ccc(N2CCN(Cc3cccc([N+](=O)[O-])c3)CC2)cc1
