Problem statement: Answer the MCQ question.
Query: Which drug exhibits a -13.031\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
[a] C=CCN1CC(C)/C(=N\O)CC1C
[b] O=C(CCl)Nc1cccc(-c2cnc3ccccc3n2)c1
[c] Cc1cc(C)cc(C(=O)Nc2ccc(N3CCN(S(C)(=O)=O)CC3)cc2)c1
[d] C=CCNC(=O)CN1CCC(c2nc3cc(C)c(C)cc3[nH]2)CC1
[e] CCCn1c(CN2CCN(C(=O)OCC)CC2)nc2cc([N+](=O)[O-])ccc21
Answer: e. CCCn1c(CN2CCN(C(=O)OCC)CC2)nc2cc([N+](=O)[O-])ccc21
