Problem statement: Answer the MCQ question.
Query: Which drug exhibits a 5.168\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: COc1ccccc1-c1nc(=S)c(C(C)=O)c(C)[nH]1
b: O=C(O)C(C(=O)/C=C/c1ccco1)=C1SCCS1
c: CN(C)c1ccc(CN(C(=O)c2cccs2)C2CCS(=O)(=O)C2)cc1
d: CC(C)(C)C(=O)c1cn(CC(=O)NCc2ccco2)c2ccccc12
e: CN(Cc1ccc(F)cc1)C(=O)c1cccc(S(=O)(=O)N2CCN(c3ccccc3)CC2)c1
Answer: b. O=C(O)C(C(=O)/C=C/c1ccco1)=C1SCCS1
