Problem statement: Answer the MCQ question.
Question: Which drug has a 2.666% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a) O=C(C1CC(c2ccc(F)cc2)=NO1)N1CCCCC1
b) C[N+](C)(CC#Cc1ccccc1)CC(=O)c1ccc(Cl)cc1
c) O=C(/C=C/c1ccc([N+](=O)[O-])o1)NNC(=O)c1ccc(F)cc1
d) O=C(NCCC1CCCCN1S(=O)(=O)c1ccccc1)C(=O)NCc1ccccc1F
e) CC(C)(C)NC(=O)C(c1ccco1)N(C(=O)Cn1nnc(-c2ccc(F)cc2)n1)c1ccccc1F
Answer: c. O=C(/C=C/c1ccc([N+](=O)[O-])o1)NNC(=O)c1ccc(F)cc1
