Task: Answer the multiple choice question.
Question: Which drug exhibits a -3.634\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a O=C(NCc1ccco1)C(c1cccs1)N(C(=O)C1COc2ccccc2O1)c1cccc(O)c1
b CCOC(=O)CC1=CC(=O)Nc2ccccc2N1
c O=C1NC2(Nc3ccccc31)C(=O)Nc1ccc(Br)cc12
d COc1ccccc1-c1nnc(SCc2nc3ccccc3[nH]2)n1C
e COc1ccccc1-c1cc(C(=O)Nc2cc(C)nn2-c2ccccc2)no1
Answer: a. O=C(NCc1ccco1)C(c1cccs1)N(C(=O)C1COc2ccccc2O1)c1cccc(O)c1
