Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 1.866\% 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, d, or e without using any other words.
Options:
a CCOc1nc(NCCC2=CCCCC2)nc(N2CCOCC2)n1
b CCOC(=O)CCSc1cc(C)c2ccccc2n1
c CC(C)CNC(=S)NC(=O)c1ccc(Cl)cc1
d COCCn1c(N)c(C(=O)NCc2cccs2)c2nc3ccccc3nc21
e Cc1cnc(-c2nnc(N(C)C(=O)c3cccnc3)s2)cn1
Answer: a. CCOc1nc(NCCC2=CCCCC2)nc(N2CCOCC2)n1
