Task: Answer the multiple choice question.
Query: What is the human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM of a compound with the SMILES CCOC(=O)/C(C#N)=C/c1ccc(N2CCN(C)CC2)cc1?
Constraint: You must return none, one or more options from a or b without using any other words.
Options:
a. -7.629
b. 16.626
Answer: a. -7.629\%.
{#Task|Problem statement!}: Answer the {#multiple choice|multiple-choice|MCQ!} question.
{#Question|Query!}: What is the {herg_central_at_1uM__names__noun} of a {#compound|drug!} with the {SMILES__description} {SMILES#}?
Constraint: You must return none, one or more options from {%multiple_choice_enum%2-5%aA1} without using any {#other|additional!} words.
Options:
{herg_central_at_1uM%SMILES%}
Answer: {%multiple_choice_result}. {herg_central_at_1uM#}{herg_central_at_1uM__units}.
CCOC(=O)/C(C#N)=C/c1ccc(N2CCN(C)CC2)cc1
