Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -4.592\% human ether-à-go-go related gene (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 other words.
Options:
(a) O=C(CN1CCN(C(=O)C2CCCO2)CC1)Nc1ccc(F)cc1
(b) Cc1c(NC2(c3nnnn3-c3ccc(Br)cc3)CCCCC2)c(=O)n(-c2ccccc2)n1C
(c) O=C(NCCC(=O)N1CCN(c2ccccc2O)CC1)c1ccc(Br)cc1
(d) Cc1nc2sccn2c(=O)c1S(=O)(=O)Nc1cccc(Cl)c1C
(e) Cc1cc(NC(=O)CSc2nnc(CNC(=O)c3ccc(F)cc3)o2)no1
Answer: a. O=C(CN1CCN(C(=O)C2CCCO2)CC1)Nc1ccc(F)cc1
