Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -3.285\% 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. O=C(NC(=S)Nc1ccc(N2CCOCC2)c(Cl)c1)c1cccs1
b. CCn1c(C(O)c2ccccc2)nc2ccccc21
c. O=C(COc1ccccc1Br)N1CCN(c2ccccc2)CC1
d. COc1ccc2nc(NP(=O)(c3ccccc3)c3ccccc3)sc2c1
e. Cc1cc(/C=C2/NC(=O)NC2=O)c(C)n1-c1cccnc1
Answer: c. O=C(COc1ccccc1Br)N1CCN(c2ccccc2)CC1
