Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -1.453\% 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 additional words.
Options:
a) CCOc1cc2c(cc1OCC)-n1cccc1C(c1cc(C)c(OC)cc1C)NC2.Cl
b) COC(=O)C1(C)NC(c2ccc(O)cc2)C2C(=O)N(c3ccccc3)C(=O)C21
c) Br.CCOCc1cn(CC(=O)c2ccc([N+](=O)[O-])cc2)c(C)nc1=N
d) CCOC(=O)C1=C(c2ccccc2)NC(=S)NC1c1ccc(Cl)cc1
e) C=CCn1c(SCC(=O)NCC(=O)OCC)nnc1-c1cccc(OC)c1
Answer: c. Br.CCOCc1cn(CC(=O)c2ccc([N+](=O)[O-])cc2)c(C)nc1=N
