Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 12.459\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a. CCOC(=O)c1[nH]c(C)c(/C(O)=C2\C(=O)C(=O)N(CCCn3ccnc3)C2c2ccncc2)c1C
b. COc1cccc(CNC(=O)C(=O)NCC2OCCCN2S(=O)(=O)c2cc(C)ccc2C)c1
c. Cc1cc(C)n2nc(C(=O)Nc3ccc(S(=O)(=O)N4CCCC4)cc3)nc2n1
d. COC(=O)[C@@H]1C[C@H]1[C@@H](NC(=O)c1ccccc1)c1ccccc1
Answer: a. CCOC(=O)c1[nH]c(C)c(/C(O)=C2\C(=O)C(=O)N(CCCn3ccnc3)C2c2ccncc2)c1C
