Problem statement: Answer the multiple choice question.
Question: Which compound has a 2.410\% 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 or b without using any other words.
Options:
[a] C=CCn1c(NCc2c[nH]c3ccccc23)nc2ccccc21
[b] CC(C)(O)CC[C@@H](O)[C@](C)(O)[C@H]1CC[C@@]2(O)C3=CC(=O)[C@@H]4C[C@@H](O)[C@@H](O)C[C@]4(C)C3CC[C@]12C
Answer: a. C=CCn1c(NCc2c[nH]c3ccccc23)nc2ccccc21
