General Description:

Papain, identified by CAS number 9001-73-4, is a notable compound with significant therapeutic applications. Papain, also known as papaya proteinase I, is a cysteine protease (EC 3.4.22.2) enzyme that is found in species of papaya, _Carica papaya_ and _Vasconcellea cundinamarcensis_. The enzyme is found to be localized in the skin of papaya, and is collected from slashed unripe papayas as a crude latex. Papain is used in food, pharmaceutical, textile, and cosmetic industries. While it has been used for the treatment of inflammation and pain via topical administration, papain has also shown to have anthelmintic and tooth-whitening properties. Present in over-the-counter mixture products consisting of different digestive enzymes, its active site contains a catalytic diad that plays a role in breaking peptide bonds. Papain is also used as an ingredient in various enzymatic debriding preparations.

Pharmacodynamics:

Papain exerts its therapeutic effects through: Papain is a digestive enzyme and often acts as a skin allergen. The drug's ability to modulate various physiological processes underscores its efficacy in treating specific conditions.

Mechanism of Action:

Papain functions by: When topically applied, papain induces an allergen-like inflammatory response via recruiting neutrophils, mast cells, and CD3-positive cells and by induction of a TH2-biased antibody response . _In vitro_, treatment of papain resulted in the breakdown of tight junctions of primary human keratinocytes that maintain the epithelial barrier integrity. These tight junction proteins include zonula occludens-1, claudin-4, and occludin . It is proposed that papain induces allergic responses via activation of TLR4, leading to an increase in neutrophils, CD3+ cells, mast cells, and CCL8-positive cells . This mechanism highlights the drug's role in inhibiting or promoting specific biological pathways, contributing to its therapeutic effects.
