Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 13.770% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
[a] COc1cc(/C=N/N=C(N)N)ccc1OCc1ccc(Cl)cc1
[b] CCOC(=O)c1c(C)[nH]c(N=Nc2ccc(C)cc2)c1C
[c] CCOC(=O)C(=NCCCN(C)C)NNc1ccc(Br)cc1
[d] Cc1cc(C)c2cc(CN(Cc3ccc4c(c3)OCO4)Cc3nnnn3Cc3ccco3)c(=O)[nH]c2c1
[e] COc1ccc(CS(=O)c2nc(C)cc(C)c2S(C)(=O)=O)cc1
Answer: b. CCOC(=O)c1c(C)[nH]c(N=Nc2ccc(C)cc2)c1C
