Problem statement: Answer the multiple choice question.
Question: Which drug has a 18.017\% 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) COc1ccc(-n2c(C)cc(C(=O)COC(=O)c3cc(NC(=O)c4cccs4)c(OC)c(OC)c3)c2C)cc1
(b) Fc1ccc(/C=N/NC(=S)Nc2ccc(Cl)cc2Cl)cc1
(c) O=S1(=O)N=C(Nc2nncs2)c2ccccc21
(d) O=C1C2CC=C(Cl)CC2C(=O)N1CN(Cc1ccco1)CN1C(=O)C2CC=C(Cl)CC2C1=O
(e) Cc1oc2c(C)c3oc(=O)c(CCC(=O)N4CCC(C(=O)NCCC(=O)O)(c5ccccc5)CC4)c(C)c3cc2c1C
Answer: c. O=S1(=O)N=C(Nc2nncs2)c2ccccc21
