Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -6.495\% 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, c, d, or e without using any additional words.
Options:
a) CCc1ccc(OCC(=O)Nc2ccc3c(c2)COC3=O)cc1
b) CCn1cc(/C=C(\NC(=O)c2ccccc2OC)C(=O)N2CCN(C)CC2)c2ccccc21
c) COC(=O)Cc1c(C)nc2nc(NCc3cccc([N+](=O)[O-])c3)[nH]n2c1=O
d) COC(OC)c1ccc(C#N)c(SCc2ccc(C)cc2)n1
e) COc1ccc2nc(-c3ccc(Cl)cc3)cc(C(=O)O)c2c1
Answer: a. CCc1ccc(OCC(=O)Nc2ccc3c(c2)COC3=O)cc1
