4-Hydroxyphenyl acetate (4-HPA) is a natural antioxidant and protects cells from oxidative stress-induced necrosis. 4-Hydroxyphenyl acetate blocks the increase of cellular ROS induced by oxidative stress, and up-regulates NQO1 and HO-1 genes by stabilizing and inducing the nuclear translocation of NRF2 transcription factor.

MAHMA NONOate is a NO donor. MAHMA NONOate effectively inhibits platelet aggregation induced by either collagen or ADP.

PAPA NONOate is a NO donor with a NO release half-life of 77 min (22-25°C). PAPA NONOate may represent a potential treatment for impaired wound healing in diabetes by increasing the rate of collagen synthesis at the wound site.

Virodhamine is an endocannabinoid, it regulates neurotransmission by activating the cannabinoid (CB) receptors. Virodhamine is an antagonist of CB1 receptor and an agonist of CB2 receptor. Virodhamine induces megakaryocytic differentiation by triggering MAPK signaling and ROS production. Virodhamine can be used for the research of various neurological disorders such as Alzheimer's and Parkinson's diseases.
