Clematis crassifolia Benth.

Anemonin (Pulsatilla camphor; Anemonine; trans-Anemonin) is a naturally occurring bislactone small molecule derived from Ranunculaceae with blood-brain barrier permeability, possessing a variety of activities including anti-inflammatory, antioxidant, neuroprotective, melanogenesis-inhibiting, and antiparasitic effects. Anemonin inhibits iNOS to reduce NO release; it inhibits PKC-θ protein expression and downregulates the pro-inflammatory factors TNF-α, IL-1β, and IL-6; it enhances the activities of the antioxidant enzymes SOD, CAT, and GSH-Px, and reduces MDA and ROS levels. Anemonin modulates the Bcl-2 / Bax / caspase-3 pathway to inhibit apoptosis; it downregulates melanogenesis-related molecules including MITF, TYR, TRP1, and TRP2, thereby inhibiting melanin synthesis in human melanocytes. Anemonin inhibits Leishmania and Schistosoma mansoni. Anemonin is used in research related to diseases such as hyperpigmentation, cerebral ischemia/reperfusion injury, inflammation, sepsis-induced acute lung injury, acute ulcerative colitis, leishmaniasis, and schistosomiasis.
