Biological Activity

[Description]:

Bromelain is an anti-inflammatory drug derived from pineapple stem that acts through down-regulation of plasma kininogen, inhibition of Prostaglandin E2 expression, degradation of advanced glycation end product receptors and regulation of angiogenic biomarkers as well as antioxidant action upstream in the COX-pathway[1]. Bromelain exhibits various fibrinolytic, antiedematous, antithrombotic, and anti-inflammatory activities. Bromelain also possesses some anticancerous activities and promotes apoptotic cell death[2].

[In Vivo]

Bromelain (40 mg/kg; intraperitoneal injection; daily; for 7 days; male Sprague-Dawley rats) pretreatment reduces the motor dysfunction in the parkinsonian rat model of parkinson's disease (PD). 6-OHDA injection resulted in marked motor impairment which is prevented by pretreatment with Bromelain prior to the lesion[1]. Animal Model: Male Sprague-Dawley rats injected with 6-OHDA[1] Dosage: 40 mg/kg Administration: Intraperitoneal injection; daily; for 7 days Result: Reduced the motor dysfunction in the parkinsonian rat model of parkinson's disease (PD).
