Problem statement: Answer the multiple choice question.
Query: Which drug has a 5.230\% 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. S=c1[nH]nc(-c2cccnc2)n1/N=C/C=C/c1ccco1
b. COc1ccccc1CCc1nnc(CCC(=O)NC(C)Cc2ccsc2)o1
Answer: a. S=c1[nH]nc(-c2cccnc2)n1/N=C/C=C/c1ccco1
