Descriptions:
In vitro, procyanidin C1 (PC1) dose-dependently decreased Fc epsilon RI-mediated degranulation and cytokine production of mast cells, inhibited tyrosine phosphorylation of Syk and linker for activation of T cells, and the ROS generation in stimulated mast cells.PC1 suppresses Fc epsilon RI-mediated mast cell activation by inhibiting intracellular signaling pathways, These observations provide evidence for the anti-allergenic effects of the procyanidin-enriched apple extract.[1]
Procyanidin C1-induced vasorelaxation is associated with the activation of the calcium-dependent NO/cGMP pathway, involving potassium channel activation, thus, it may represent a novel and potentially therapeutically relevant compound for the treatment of cardiovascular diseases.[2]
Procyanidin C1 is the main active compound in the CC extract responsible for EMT inhibition and that procyanidin C1 could be useful as a lead compound to develop inhibitors of cancer metastasis and other diseases related to EMT.[3]
Procyanidin C1 has anti-inflammatory effects, can inhibit IKKb activity in vitro and reduce the LPS-induced production of ROS, thus, it exerts the anti-inflammatory effects by inhibiting ERK1/2 and IKKb activity.[4]
