Problem statement: Answer the MCQ question.
Query: Which drug exhibits a 15.981\% 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, or c without using any other words.
Options:
[a] CCc1[nH]c(=S)c(C#N)c2c1CCCC2
[b] COC(=O)CCC(=O)OC1(C)C(=O)C2=COC(c3ccc(OC)cc3)=CC2=C(Br)C1=O
[c] O=[N+]([O-])c1cccc(-c2cnc3ccccc3n2)c1
Answer: b. COC(=O)CCC(=O)OC1(C)C(=O)C2=COC(c3ccc(OC)cc3)=CC2=C(Br)C1=O
