Task: Answer the multiple choice question.
Question: Which drug exhibits a 1.661\% human ether-à-go-go related gene (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 other words.
Options:
a.) CCn1cc(C(=O)N2CCN(c3ccc(OC)cc3)CC2)c2cc(OC)c(OC)cc2c1=O
b.) COc1ccc(NC(=O)CSc2ccc(-c3cccnc3)nn2)c(OC)c1
c.) COc1ccc(-c2ccc(SCc3cccnc3)nn2)cc1OC
d.) CCCC1=NN2C(=N)/C(=C\c3cc(C)n(-c4cc(C)cc(C)c4)c3C)C(=O)N=C2S1
e.) Cc1ccc(S(=O)(=O)N(c2ccc(C)c(C)c2)c2ccccn2)cc1
Answer: d. CCCC1=NN2C(=N)/C(=C\c3cc(C)n(-c4cc(C)cc(C)c4)c3C)C(=O)N=C2S1
