Problem statement: Answer the MCQ question.
Query: Which drug has a 6.913\% 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] CCO[C@@H]1OC(C(=O)N2CCOCC2)=C[C@H](c2coc3ccccc3c2=O)[C@H]1CCCO
[b] O=C(COC(=O)c1ccc(Br)o1)NCCNC(=O)COC(=O)c1ccc(Br)o1
[c] Cc1[nH]nc2c1C(c1cccs1)C1=C(CC(C)(C)CC1=O)N2
[d] CC(C)(C)n1nnnc1CN(Cc1cccnc1)Cc1ccccc1Cl
[e] Cc1ccccc1-c1nc(CS(=O)(=O)CC(=O)NC2CCCC2)c(C)o1
Answer: a. CCO[C@@H]1OC(C(=O)N2CCOCC2)=C[C@H](c2coc3ccccc3c2=O)[C@H]1CCCO
