Task: Answer the multiple-choice question.
Question: Which drug exhibits a -3.142\% 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) COc1cc2c(cc1OC)C(=S)NC(C)(C)C2
(b) O=c1c2cc(Br)ccc2nc2n1CCCCC2
(c) O=C(c1cc(-c2ccccn2)nc2c(Cl)cccc12)N1CCN(C(=O)C2CCCO2)CC1
(d) C=CCN1C(=O)C(O)(CC(=O)c2ccccc2)c2ccccc21
(e) Nc1nc(NC(=O)CCc2ccccc2)nn1-c1ccccc1
Answer: b. O=c1c2cc(Br)ccc2nc2n1CCCCC2
