Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 5.864\% 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, b, c, or d without using any other words.
Options:
[a] COc1ccc2[nH]c(=O)c(C(c3nnnn3C3CCCCC3)N3CCN(C)CC3)cc2c1
[b] CC1(CCl)CN1S(=O)(=O)c1ccccc1
[c] CCOc1ncccc1C(=O)OCC(=O)Nc1ccc(C)c(S(=O)(=O)N2CCOCC2)c1
[d] CN(C)c1ccc(C2CC(=O)OC3=C2C(=O)CC(C)(C)C3)cc1
Answer: c. CCOc1ncccc1C(=O)OCC(=O)Nc1ccc(C)c(S(=O)(=O)N2CCOCC2)c1
