Problem statement: Answer the MCQ question.
Query: Which drug exhibits a 3.378\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a. CCOC(=O)/C(N=Nc1cc(C(=O)O)cc(C(=O)O)c1)=C(\O)CCl
b. Cc1cc(C)n2nc(SCc3cccc(S(=O)(=O)N(C)C)c3)nc2n1
Answer: a. CCOC(=O)/C(N=Nc1cc(C(=O)O)cc(C(=O)O)c1)=C(\O)CCl
