TMPAはNur77拮抗剤であり、Nur77とLKB1の結合を阻止し、細胞質へのLKB1の輸送とリン酸化を刺激する[1]。TMPAとNur77の結合は、Nur77の開閉動作を誘発することで、Nur77-LKB1複合体の安定性を減らし、よって界面領域の溶媒和を促進する[2]。TMPAは糖尿病マウスモデルに広く使われ、血糖レベルを調節する[3]。
体外で、10μMのTMPAの1時間の処理は、肝臓L02細胞で、AMPKのリン酸化を増やした[4]。10μM TMPAでマウス骨髄由来の肥満細胞(BMMC)を6時間処理した結果、LKB1とAMPKのリン酸化を増やし、IgE/Ag誘導性脱顆粒とエイコサノイドの産生を同時に減らし、FcεRI媒介の肥満細胞のシグナル伝達を阻害した[5]。10μM TMPAの18時間の処理は、HeLa細胞で、TNFα誘発のIL-6の産生を著しく増やした[6]。10μM TMPAでHepG2細胞を6時間事前処理した結果、遊離脂肪酸(FFA)刺激後の脂質の蓄積を減らした[7]。
体内で、TMPA (50mg/kg/日)を19日間、毎日一回腹腔内注射した結果、糖尿病マウスで、インスリンのレベルを著しく減らし、血糖を低くし、耐糖性を改善した[8]。
