Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 5.305\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
(a) CN1C(=O)CC(C(=O)O)SC1=Nc1cc(Cl)c(O)c(Cl)c1
(b) CCCNS(=O)(=O)c1ccc(OC)c(Cl)c1Cl
(c) COc1ccc(CN(C(=O)Cn2nnc3ccccc32)C(C(=O)NC(C)(C)C)c2ccco2)cc1
(d) Cc1cccn2c(=O)c3cc(S(=O)(=O)c4ccc(Br)cc4)c(=N)n(C4CCCCC4)c3nc12
(e) O=C(CN1CCN(c2ccccn2)CC1)N1CCc2ccccc21
Answer: a. CN1C(=O)CC(C(=O)O)SC1=Nc1cc(Cl)c(O)c(Cl)c1
