Task: Answer the multiple choice question.
Question: Which compound has a 4.399% 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 other words.
Options:
a: CCCCC(=O)Nc1ccc2c(c1)nc(CN1CCN(C(=O)OCC)CC1)n2C
b: NS(=O)(=O)c1ccc(NC(=O)CN2CCc3ccccc32)cc1
c: O=c1c2c3c(sc2ncn1/N=C/c1ccco1)CCCC3
d: CCOC(=O)N1CCC(NC(=S)Nc2ccc3nc(N4CCN(CC)CC4)cc(C)c3c2)CC1
e: COc1ccc(CCNC(=O)c2cccc(S(=O)(=O)N3CCCCCC3)c2)cc1
Answer: a. CCCCC(=O)Nc1ccc2c(c1)nc(CN1CCN(C(=O)OCC)CC1)n2C
