Problem statement: Answer the MCQ question.
Question: Which drug exhibits a -34.021\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
(a) O=C(CCCNS(=O)(=O)c1cccs1)N1CCc2ccccc2C1
(b) CCN(CC)C1=NC=CC(c2ccccc2)=CC1C
(c) O=C(C1CCCN1S(=O)(=O)c1ccc(Cl)c(Cl)c1)N1CCCCC1
(d) COC(=O)c1oc2ccc(Br)cc2c1NC(=O)c1ccccc1
(e) COc1ccc(C2CC(c3ccccc3O)=NN2c2ccccc2)cc1
Answer: b. CCN(CC)C1=NC=CC(c2ccccc2)=CC1C
