khellin/neoplasms

Cytochrome P450 family 1 (CYP1) enzymes catalyze the metabolic activation of environmental procarcinogens such as benzo[a]pyrene, B[a]P, into carcinogens, which initiates the process of carcinogenesis. Thus, stopping the metabolic activation of procarcinogens can possibly prevent the

This study was performed to assess the effectiveness and short-term and long-term safety of oral khellin plus UVA (KUVA) in patients with vitiligo. Twenty-eight patients (13 males and 15 females; mean age, 34 years; [age range, 15-51 years]) most with extensive generalized vitiligo of more than 6

Cytotoxic effect of five known compounds, khellin, berberine, lupeol, scopolin, rapanone, obtained from Colombian plants, were determined against human tumor cell lines as an indicator of the potential anticancer activity of these compounds. Berberine and rapanone presented interesting cytotoxicity.

Mast cells play a critical role in type 1 hypersensitivity reactions. Indeed, mast cell mediators are implicated in many different conditions including allergic rhinitis, conjunctivitis, asthma, psoriasis, mastocytosis and the progression of many different cancers. Thus, there is intense interest in
