Novel diphenylpiperazine derivatives were synthesized and evaluated for their inhibitory activity against T-type calcium channel by whole-cell patch clamp recordings on HEK293 cells. Among the test compounds, 2 and 3d were effective in decreasing the response to formalin in both the first and second phases and demonstrated antiallodynic effects in a rat model of neuropathic pain.
