Task: Answer the multiple choice question.
Question: What is the human ether-à-go-go related gene (hERG) inhibition at 1uM of a compound with the SMILES CNC(=O)/C(C#N)=C/c1c(N2CCN(C)CC2)nc2c(C)cccn2c1=O?
Constraint: You must return none, one or more options from a or b without using any additional words.
Options:
a.) 13.738
b.) 16.393
Answer: a. 13.738\%.
{#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}.
CNC(=O)/C(C#N)=C/c1c(N2CCN(C)CC2)nc2c(C)cccn2c1=O
CNC(=O)/C(C#N)=C/c1c(N2CCN(C)CC2)nc2c(C)cccn2c1=O
(E)-2-cyano-N-methyl-3-[9-methyl-2-(4-methylpiperazin-1-yl)-4-oxopyrido[1,2-a]pyrimidin-3-yl]prop-2-enamide
