Problem statement: Answer the multiple choice question.
Question: Which drug has a 3.802\% 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] Cc1ccc(C)c(S(=O)(=O)N2CCN(c3ncccn3)CC2)c1
[b] O=C(Nc1cccc(N=Cc2cc(Cl)cc(Br)c2O)c1)c1ccco1
[c] CCOC(=O)CCc1c(C)c2ccc(OCc3cc([N+](=O)[O-])ccc3OC)c(C)c2oc1=O
[d] CC(C)CNC(CC(=O)Nc1cccc([N+](=O)[O-])c1)C(=O)O
[e] NC(=O)c1ccsc1NC(=O)COC(=O)c1ccc([N+](=O)[O-])o1
Answer: b. O=C(Nc1cccc(N=Cc2cc(Cl)cc(Br)c2O)c1)c1ccco1
