Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 1.641\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a) C/C=C/Cn1c(SCc2ccc(C)cc2)nc2c1c(=O)[nH]c(=O)n2C
b) COc1ccc(C(=O)Nc2ccccc2C(=O)Nc2cccc(C)n2)cc1
Answer: a. C/C=C/Cn1c(SCc2ccc(C)cc2)nc2c1c(=O)[nH]c(=O)n2C
