Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 8.366\% 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. CCCCOC(=O)C1=C(N)OC2=C(C(=O)CCC2)[C@]12C(=O)N(C)c1ccccc12
b. COC(=O)C(NC(=O)c1cccnc1Cl)C(C)C
c. CCOC(=O)c1c(C)[nH]c(C(=O)OCC(=O)c2ccccc2)c1C
d. COc1ccc(-c2c(C3=CCCCC3)oc3ccc(-c4ccc5c(c4)OCO5)cc23)cn1
e. O=C(c1ccc2c3c(cccc13)CC2)C1CCCN(C(=O)c2cc[n+]([O-])cc2)C1
Answer: c. CCOC(=O)c1c(C)[nH]c(C(=O)OCC(=O)c2ccccc2)c1C
