Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 19.039\% 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: Cc1nnc(SCC(=O)NCc2cccs2)[nH]c1=O
b: COc1ccc(CCNC(=O)Cn2cccc2C(=O)c2ccccc2C)cc1OC
c: Cc1cc(N(C)/N=C/c2ccccc2)nc(-c2ccccc2O)n1
d: COCCNC(=O)c1cc2sccc2n1C
e: COc1ccc(OC)c(NC(=O)CSc2nc(N3CCOCC3)nc(N3CCOCC3)n2)c1
Answer: a. Cc1nnc(SCC(=O)NCc2cccs2)[nH]c1=O
