Task: Answer the multiple choice question.
Question: Which drug exhibits a -20.931\% 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 other words.
Options:
(a) CCOC(=O)c1cnc(SCC(=O)Nc2cc(OC)ccc2OC)nc1N
(b) O=C(CSc1nc(Nc2ccccc2)nc(N2CCOCC2)n1)Nc1ccccc1Cl
(c) CCOC(=O)Cn1c(=N)n(CCOc2ccc3ccccc3c2)c2ccccc21.Cl
(d) COc1cccc(CSc2nc3ccccc3cc2C=O)c1
(e) NS(=O)(=O)c1cc(Cl)c(Cl)c(S(N)(=O)=O)c1
Answer: c. CCOC(=O)Cn1c(=N)n(CCOc2ccc3ccccc3c2)c2ccccc21.Cl
