Task: Answer the multiple choice question.
Question: Which compound exhibits a -19.850\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
[a] COc1cc(OC)c(C(=O)Nc2cccc3ccccc23)cc1OC
[b] N=c1c2c3c(sc2ncn1CCCN1CCOCC1)CCCCC3
[c] Cc1ccc(N(CC(=O)N/N=C/c2cccs2)S(C)(=O)=O)cc1Cl
[d] CCOc1ccc(CN(C)CCc2ccccn2)cc1.O=C(O)C(=O)O
[e] COc1ccccc1Oc1cn[nH]c1-c1ccc(OCC(=O)NN)cc1O
Answer: b. N=c1c2c3c(sc2ncn1CCCN1CCOCC1)CCCCC3
