Task: Answer the multiple-choice question.
Query: Which compound exhibits a 1.042\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a.) CCOC(=O)C1=C(C)NC(SCC(=O)O)=C(C#N)C1c1ccco1
b.) COc1ccc(CNc2nc3c(c(=O)[nH]c(=O)n3C)n2CCCc2ccccc2)cc1
Answer: a. CCOC(=O)C1=C(C)NC(SCC(=O)O)=C(C#N)C1c1ccco1
{#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#}
CCOC(=O)C1=C(C)NC(SCC(=O)O)=C(C#N)C1c1ccco1
CCOC(=O)C1=C(C)NC(SCC(=O)O)=C(C#N)C1c1ccco1
