Task: Answer the multiple-choice question.
Question: Which drug exhibits a 2.569\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: COc1ccccc1NC(=S)Nc1cccc(F)c1
b: O=C(NCc1ccco1)c1ccc(CN2CCOCC2)cc1
c: COc1ccc(C(=O)C2CCCN(Cc3cccn3-c3nccs3)C2)cc1F
d: COc1cccc(C=Nc2cc(C)on2)c1O
e: CC1(C)CC(=O)C2=C(C1)OC(N)=C(C#N)C2c1ccsc1
Answer: e. CC1(C)CC(=O)C2=C(C1)OC(N)=C(C#N)C2c1ccsc1
{#Task|Problem statement!}: Answer the {#multiple choice|multiple-choice|MCQ!} question.
{#Question|Query!}: Which {#compound|drug!} {#has|exhibits!} a {herg_central_at_1uM#}{herg_central_at_1uM__units} {herg_central_at_1uM__names__noun}?
Constraint: You must select none, one or more options from {%multiple_choice_enum%2-5%aA1} without using any {#other|additional!} words.
Options:
{SMILES%herg_central_at_1uM%}
Answer: {%multiple_choice_result}. {SMILES#}
CC1(C)CC(=O)C2=C(C1)OC(N)=C(C#N)C2c1ccsc1
CC1(C)CC(=O)C2=C(C1)OC(N)=C(C#N)C2c1ccsc1
