Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a -18.851\% human ether-à-go-go related gene (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(CCn1c(=S)[nH]c2ccccc2c1=O)NCCCN1CCCC1=O
[b] COc1ccc(CC(=O)Nc2c3c(nn2-c2cccc(Cl)c2)CS(=O)C3)cc1
[c] COCCn1c(=O)[nH]c2cc(C(=O)NCc3ccccc3)ccc2c1=O
[d] COc1ccc(CNC(=S)N/N=C(/C)c2ccccc2)cc1
Answer: a. O=C(CCn1c(=S)[nH]c2ccccc2c1=O)NCCCN1CCCC1=O
