Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 0.512\% 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 other words.
Options:
[a] O=C(Nc1ccc(Cl)cn1)c1cc(S(=O)(=O)N2CCCCC2)ccc1Cl
[b] CC(=O)NC(=S)Nc1ccc(S(=O)(=O)Nc2nc(C)cc(C)n2)cc1
[c] COc1ccc(NC(=O)CSc2ccc(-c3sc(C)nc3C)nn2)cc1
[d] N#Cc1c(/N=C/c2ccco2)sc2c1CCCCC2
Answer: a. O=C(Nc1ccc(Cl)cn1)c1cc(S(=O)(=O)N2CCCCC2)ccc1Cl
