Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -1.976\% 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) CCOC(=O)c1nnn(-c2nonc2N)c1-c1ccc(Br)cc1
b) CN1C(=O)CSc2ccc(NC(=O)N3CCOCC3)cc21
c) O=C(CN1CCCC1)Nc1nnc(-c2cccs2)s1
d) OC(C#CCN1CCCC1)(c1ccccc1)c1ccccc1
e) O=S(=O)(Nc1ccc(-c2cnco2)cc1)c1ccccc1
Answer: b. CN1C(=O)CSc2ccc(NC(=O)N3CCOCC3)cc21
