Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 3.996\% 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) CCCCn1c(NS(=O)(=O)c2ccc(C)cc2)c(S(=O)(=O)c2ccccc2)c2nc3ccccc3nc21
b) CCOC(=O)c1cc(CC)sc1/N=C/C1=C(O)CCCC1=O
c) COCCNS(=O)(=O)c1cc(-c2nn(C)c(=O)c3ccccc23)ccc1C
d) CC(Cc1n[nH]c(=S)n1N)c1ccccc1
e) COc1ccccc1C(=O)Nc1ccc(C(=O)N2CCCC2)cc1
Answer: b. CCOC(=O)c1cc(CC)sc1/N=C/C1=C(O)CCCC1=O
