Objective:To synthesize BP897, a dopamine D3 receptor partial agonist.

Eugenol, cinnamic alcohol, phenyl methyl alcohol and phenyl ethyl alcohol have shown to be potential antagonists or partial agonists to octopaminergic receptors in pharmacologic studies.

Since varenicline is only a partial agonist—not a full agonist—at the alpha4beta2 receptor site, it performs differently in smokers and nonsmokers, she said.
