Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a -1.764\% 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, d, or e without using any additional words.
Options:
[a] CCOC(=O)C1(CCOc2ccccc2)CCN(Cc2cccc3nonc23)CC1
[b] O=C(c1cccc(Br)c1)N1CCN(C(=O)N2CCOCC2)CC1
[c] O=C(CN1CCCCC1)N/N=C/c1ccc(Cl)cc1Cl
[d] COc1ccc(S(=O)(=O)NCc2cccnc2)cc1C(=O)N1CCCCC1
[e] Cc1ccc(Cl)cc1NC(=O)c1ccc(Cn2cc(Cl)cn2)cc1
Answer: c. O=C(CN1CCCCC1)N/N=C/c1ccc(Cl)cc1Cl
