Bromeliaceae

Stem bromelain (EC 3.4.22.32) is a cysteine protease and antibacterial agent. Stem bromelain can be isolated from the stem of the pineapple (Ananas comosus). Stem bromelain induces dose-dependent secretion of IL-12p70, and IL-6, induces Apoptosis, causes cleavage of full-length PARP protein, Caspase 3, and Caspase 9, increases Bax, and decreases Bcl-2. Stem bromelain possesses various fibrinolytic, antiedema, antithrombotic, and anti-inflammatory activities. Stem bromelain also exhibits in vivo antitumor and antileukemic activities, as well as antimetastatic effects. Stem bromelain has antimycobacterial activity. Stem bromelain provides protection against lead poisoning.

2-Methylbutanoic acid is a chemical intermediate for a variety of applications such as plasticizers, lubricants and pharmaceuticals.

2,3-Dimethylmaleic anhydride is biofumigant found in Colocasia esculenta var. esculenta (L.) Schott. 2,3-Dimethylmaleic anhydride is highly toxic to insect pests for stored grains even at very low concentration, but has no adverse effect on seed germination. 2,3-Dimethylmaleic anhydride can be used as insecticide.

4-Methylthiophene is an intermediate used in the synthesis of the aromatic sulfur compounds.

Ananasin A is a natural flavonoid.
