Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a -2.638\% 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 C=CCn1c(O)c(C=NC2CCN(Cc3ccccc3)CC2)c(=O)[nH]c1=O
b CCc1sc(C(=O)Nc2cccnc2)cc1Br
c Cc1ccc(CNC(=O)C(=O)NCC2OCCN2S(=O)(=O)c2ccc(Br)cc2)cc1
d COc1ccc(OC)c2[nH]c(=O)c(CCNC(=O)c3cc4ccccc4o3)cc12
e CC(C)C(=O)Nc1ccc(Oc2ccccc2)cc1
Answer: a. C=CCn1c(O)c(C=NC2CCN(Cc3ccccc3)CC2)c(=O)[nH]c1=O
