Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a -34.794% 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) CC(C)CCn1c(N2CCN(c3cccc(Cl)c3)CC2)nc2c1c(=O)[nH]c(=O)n2C
(b) COc1ccc(OC)c(NC=C2C(=O)OC(C)(C)OC2=O)c1
(c) O=c1[nH]c(=S)n(Cc2ccc(F)cc2)c(O)c1C=NCC1CCCO1
(d) COc1ccc(CCNC(=O)CSc2nc3[nH]ncc3c(=O)n2-c2ccc(Br)cc2)cc1OC
(e) COc1ccc(OC)c(NC(=O)CC(NC(C)=O)c2ccccc2)c1
Answer: a. CC(C)CCn1c(N2CCN(c3cccc(Cl)c3)CC2)nc2c1c(=O)[nH]c(=O)n2C
