Task: Answer the multiple choice question.
Question: Which compound exhibits a 5.841\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a) O=C(CCCn1c(=S)[nH]c2cc3c(cc2c1=O)OCO3)N1CCN(c2ccc(Cl)cc2)CC1
b) CC(=O)c1ccc(N2CCN(S(=O)(=O)c3c(C)[nH]c(C)c3C(=O)N3CCCC3)CC2)cc1
c) N#Cc1c(N)nc2c(c1N)CC(=O)N2c1ccccc1-c1ccccc1
d) COc1ccc(S(=O)(=O)N(C)CC(=O)NCCCN2CCOCC2)cc1Cl
Answer: a. O=C(CCCn1c(=S)[nH]c2cc3c(cc2c1=O)OCO3)N1CCN(c2ccc(Cl)cc2)CC1
