| Description | Vicenin 2 is an angiotensin-converting enzyme (ACE) inhibitor (IC50=43.83 μM) from the aerial parts of Desmodium styracifolium. Vicenin 2 is an inhibitor of α-glucosidase, PTP1B, and RLAR. Vicenin 2 has hepatoprotective, anti-cancer, antioxidant and anti-inflammatory activities, and DTL co-administration is more effective than either of the single agents in androgen-independent prostate cancer. Vicenin 2 might be a useful lead for the development of multiple target-oriented therapeutic modalities for the treatment of diabetes and diabetes-associated complications. Vicenin 2 could act as a UV light barrier to protect the plants. |
| In vitro | Lychnophora salicifolia, commonly known as 'arnicão', is used as an anti-inflammatory agent and as a flavoring agent in the Brazilian traditional spirit 'cachaça'.METHODS AND RESULTS: In this work, the permeation process of Vicenin -2 (1) and lychnopholic acid (2) (major secondary metabolites from the hydroalcoholic extract) was investigated using Caco-2 cells. For this investigation, a new HPLC-DAD method was developed and validated for the quantification step. It was observed that 2 crosses the Caco-2 cell monolayer by passive diffusion. On the other hand, 1 was not transported, suggesting no absorption and no efflux of this compound in Caco-2 cells. |
