Task: Answer the multiple-choice question.
Question: Which drug exhibits a -3.698\% 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 CC1=C(C(N)=O)C(c2cccs2)NC(=S)N1
b CCn1nc(C)c(NC(=O)/C=C/c2ccc(OC)c(COc3ccc(Br)cc3)c2)c1C
c CSc1ncc(CN2CCN(CC=C(C)C)C(CCO)C2)cn1
d O=C(COC(=O)c1ccccc1F)Nc1cccnc1Cl
e COc1ccc(/C=C(\C#N)C(=O)OCC(=O)N2CC(C)OC(C)C2)cc1
Answer: b. CCn1nc(C)c(NC(=O)/C=C/c2ccc(OC)c(COc3ccc(Br)cc3)c2)c1C
