Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -2.878\% 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: COc1ccc(CCNC(=O)CSc2cccc3cccnc23)cc1OC
b: CCOC(=O)N1CCN(c2c(NCCCN(CC)CC)c(=O)c2=O)CC1
c: Cc1ccc(-c2nnc(N3CCN(C(=O)CN4C(=O)c5ccccc5C4=O)CC3)c3ccccc23)cc1
d: COc1cc2c(cc1OC)CN(Cc1cc(=O)oc3cc(C)c(C)cc13)CC2
e: O=C1c2ccccc2-c2ccc(C(=O)N3CCOCC3)cc21
Answer: a. COc1ccc(CCNC(=O)CSc2cccc3cccnc23)cc1OC
