Problem statement: Answer the MCQ question.
Question: Which drug has a 5.257\% 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 additional words.
Options:
[a] O=c1nc2n(Cc3ccccc3)c3ccccc3cc-2c(=O)[nH]1
[b] Cc1nc(-c2ccc(S(=O)(=O)N3CCCN(CCc4ccccc4)CC3)s2)cs1
[c] CCCCN(C)CCNS(=O)(=O)c1ccc2c(c1)n(C)c(=O)c(=O)n2C
[d] Cc1ccc(C(c2nnnn2Cc2cccs2)N2CCN(Cc3ccc4c(c3)OCO4)CC2)cc1
[e] CCOC(=O)C(C)c1nc2ccccc2[nH]c1=O
Answer: a. O=c1nc2n(Cc3ccccc3)c3ccccc3cc-2c(=O)[nH]1
