Task: Answer the multiple choice question.
Question: Which drug exhibits a -81.365% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a) O=C(O)CCCC(=O)NS(=O)(=O)c1ccc(Cl)cc1
b) O=c1nc2ccccc2c2n1CC(CN1CCN(C(c3ccccc3)c3ccccc3)CC1)N2
c) CCCCCCCNC(=O)C1(CC2CC(c3cccc(Br)c3)=NO2)CCN(C(=O)Cc2ccc(F)cc2)CC1
d) COc1ccc(S(=O)(=O)NCCN2CCOCC2)c(C)c1C
e) COC(=O)c1ccc(NC(=O)c2cccnc2)cc1
Answer: b. O=c1nc2ccccc2c2n1CC(CN1CCN(C(c3ccccc3)c3ccccc3)CC1)N2
