Problem statement: Answer the multiple choice question.
Question: Which compound has a 6.429\% 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 other words.
Options:
a: CCN(CC)S(=O)(=O)c1cccc(-c2nnc(SCCCC(=O)c3ccccc3)o2)c1
b: O=C(COC(=O)Cn1cnc2ccccc21)NCCc1ccccc1
c: COc1ccc(-c2nnc(-c3ccc(OCC(C)C)cc3)o2)cc1
d: COc1ccc(S(=O)(=O)N2CCOC2CNC(=O)C(=O)NCc2ccccn2)cc1C
e: CC(=O)N1N=C(c2ccc(C(C)(C)C)cc2)OC1(C)C
Answer: b. O=C(COC(=O)Cn1cnc2ccccc21)NCCc1ccccc1
