Bromelain 是来源于菠萝茎的一种抗炎药，可诱导细胞凋亡，具有纤维蛋白溶解、抗癌、抗水肿和抗血栓形成活性。它通过下调血浆激肽原，抑制前列腺素 E2 表达，降解晚期糖基化终产物受体，在COX途径上游发生抗氧化作用以及调节血管生成生物标志物而发挥作用。

Bromelain is an anti-inflammatory drug derived from pineapple stem. It acts through down-regulation of plasma kininogen, degradation of advanced glycation end-product receptors, inhibition of Prostaglandin E2 expression, and regulation of angiogenic biomarkers as well as antioxidant action upstream in the COX-pathway.

Bromelain (40 mg/kg; i.p.; daily; for 7 days; male SD rats) pretreatment reduces the motor dysfunction in the parkinsonian rat model of Parkinson's disease. 6-OHDA injection resulted in a marked motor impairment which is prevented by pretreatment with Bromelain prior to the lesion [1].
