Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 1.996\% 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 CCc1ccc(/C=C(/C#N)C(N)=S)s1
b O=C(COC(=O)Cn1cnc2ccccc21)NCCC1=CCCCC1
c O=C(c1ccco1)N1CCN(Cc2cc(=O)c(OCc3ccc(F)cc3)co2)CC1
d Cc1ccc(C23OC(=O)C(C)(C)C2OC(=O)C3(C)C)cc1
e CCOC(=O)Nc1nc(-c2ccccc2)c(C(=O)c2ccccc2)s1
Answer: b. O=C(COC(=O)Cn1cnc2ccccc21)NCCC1=CCCCC1
