Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 5.408\% 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 other words.
Options:
(a) C=CCn1c(CCNC(=O)C(C)(C)C)nc2ccccc21
(b) CC(/C=N/Nc1nncc(=O)[nH]1)=C\c1ccccc1
(c) O=C(COc1ccccc1[N+](=O)[O-])Nc1ccc(NC(=O)c2cc3ccccc3o2)cc1
(d) CC(C)COc1ccc(C2(C#N)CC[N+](C)(C)CC2)cc1.[Br-]
(e) CS(=O)(=O)c1ccc(-c2cccc(NC(=O)COc3ccc(Cl)cc3)c2)nn1
Answer: c. O=C(COc1ccccc1[N+](=O)[O-])Nc1ccc(NC(=O)c2cc3ccccc3o2)cc1
