Problem statement: Answer the multiple choice question.
Question: Which drug has a 6.540\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] O=C(CN1C(=O)NC2(CCOc3ccccc32)C1=O)Nc1cccc(Cl)c1
[b] COc1cccc(NC(=O)COc2cc(O)c3c(c2)OC(C)(C)CC3=O)c1
[c] N#Cc1nc(Cc2ccccc2)oc1N1CCN(c2cccc(Cl)c2)CC1
[d] COc1ccc(-n2c(SCC(N)=O)nnc2-c2ccc(NS(=O)(=O)c3ccc(C)cc3)cc2)cc1
Answer: a. O=C(CN1C(=O)NC2(CCOc3ccccc32)C1=O)Nc1cccc(Cl)c1
