Aegeline, a main alkaloid, mimics the yeast SNARE protein Sec22p in suppressing α-synuclein and Bax toxicity in yeast. Aegeline restores growth of yeast cells suppressed by either αsyn or Bax. Antioxidant activity[1].
Aegeline also prevents growth block in cells expressing the more toxic A53T α-synuclein mutant. Restoration of cell growth occurred through inhibition of increased ROS levels, mitochondrial membrane potential loss and nuclear DNA fragmentation, characteristics of apoptosis manifested in α-synuclein orBax-expressing cells[1].Aegeline shows weak inhibitory effects on the histamine release from RPMCs, even though still succeed to inhibit when the histamine release induced by thapsigargin[2].
