Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 0.499\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] O=C(Cn1ncn2c(cc3ccccc32)c1=O)NCc1ccco1
[b] CN(CC(=O)Nc1ccc(N2CCOCC2)cc1)C(=O)c1cc2c(s1)CCCC2
[c] Cc1cc(-n2c(SCC(=O)Nc3ccc(F)c(F)c3)nc3n[nH]c(C)c3c2=N)ccc1Cl
[d] O=C1c2nc3cc(-c4ccccc4)[nH]n3c(=O)c2CN1Cc1ccccc1
Answer: b. CN(CC(=O)Nc1ccc(N2CCOCC2)cc1)C(=O)c1cc2c(s1)CCCC2
