Problem statement: Answer the multiple-choice question.
Question: Which drug has a -3.895\% 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: O=c1[nH]c(=O)n(CCC2=CCCCC2)c(O)c1/C=N/N1CCOCC1
b: CCOC(=O)C1=CC[C@@H](c2ccco2)N(S(=O)(=O)c2ccc(C)cc2)[C@H]1C(=O)OCC
c: O=c1[nH]c(/C=C/c2ccccc2Cl)c([N+](=O)[O-])c(=O)[nH]1
Answer: a. O=c1[nH]c(=O)n(CCC2=CCCCC2)c(O)c1/C=N/N1CCOCC1
