Biological Activities
Juniperus squamata contains bioactive compounds that demonstrate significant antiplatelet properties. Specifically, the acetoxy derivative of cedranediol isolated from this plant has been shown to inhibit platelet aggregation induced by various agents such as ADP, collagen, and thrombin. This inhibition occurs through the suppression of thromboxane B2 formation and the breakdown of phosphoinositides. Furthermore, the compound effectively blocks the release of ATP and the rise of intracellular calcium in platelets. Such findings highlight the potential pharmacological importance of components derived from this species in managing blood clotting processes.
Compounds
Juniperus squamata serves as the natural source for the isolation of 14-acetoxycedrol, a significant acetyl derivative of the sesquiterpene 8,14-cedranediol. Research indicates that this specific compound possesses potent antiplatelet and vasorelaxing properties. Specifically, 14-acetoxycedrol inhibits platelet aggregation and the formation of thromboxane B2 induced by various agents. Furthermore, the substance demonstrates the ability to relax vascular smooth muscle by inhibiting calcium influx through voltage-dependent channels. These findings highlight the pharmacological potential of the chemical constituents found within this plant species.
Conditions
Juniperus squamata, specifically through its derivative 14-acetoxycedrol, effectively inhibits platelet aggregation and the release of ATP. The plant extract also treats the formation of inositol phosphate caused by collagen and platelet-activating factor. Furthermore, it acts to treat the rise of intracellular calcium levels in platelets. In vascular studies, the substance treats cumulative contractions induced by high K+ (60 mM) and Ca2+ (0.03-3 mM). These combined actions demonstrate the potent antiplatelet and vasorelaxing properties of the species.
