mucin

1. Obtusifolin has antioxidant properties and improves chemically induced diabetes and its complications by modulation of oxidative stress. 2. Obtusifolin suppresses phthalate esters-mediated bone resorption, thus may be a novel anti-breast-cancer bone me

Platycodin D may stimulate TNF-α synthesis or inhibit degradation of TNF-α mRNA. Platycodin D (10 30 μM) suppresses prostaglandin E2 production in rat peritoneal macrophages stimulated by the protein kinase C activator 12-O-tetradecanoyl phorbol 13-acetate (TPA). Platycodin D and D3 are useful as expectorant agents in the treatment of various airway diseases, they can increase mucin release from rat and hamster tracheal surface epithelial cell culture and also from intact rat trachea upon nebulization.

Platycodin D3 is a NF-κB inhibitor, it could as expectorants in diverse inflammatory pulmonary diseases, it can regulate the production and secretion of airway mucin; it can significantly enhance mitogen- and OVA-induced splenocyte proliferation in the OVA-immunized mice. Platycodin D3 also exerts anti-Hepatitis C virus (HCV) activity.

1. Coixol (MBOA) acts as a central muscle relaxant with an anti-convulsant effect. 2. Coixol interacts with the pituitary to stimulate reproduction in voles. 3. Coixol has the ability to interact with FSH to stimulate follicular development and increase ovulation. 4. Coixol can regulate gene expression, production and secretion of mucin, by directly acting on airway epithelial cells.

Phosphatidylserine is a naturally occurring phospholipid that comprises 2-10% of total phospholipids in mammals and is enriched in the central nervous system, particularly the retina. It is anionic and found mainly on the inner leaflet of the cell membrane. It is biosynthesized from phosphatidylcholine or phosphatidylethanolamine by phosphatidyl synthase 1 (PSS1) or PSS2, respectively, in the endoplasmic reticulum and can be reversibly converted back by the same enzymes. It can also be irreversibly converted to phosphatidylethanolamine by phosphatidylserine decarboxylase in the mitochondria. Phosphatidylserine binds to T cell immunoglobulin mucin type 1 (TIM-1) and TIM-4 receptors as well as brain-specific angiogenesis inhibitor 1 (BAI1), leading to anti-inflammatory and anti-atherosclerotic effects. It is also a cofactor involved in the activation of various signaling pathways through activation of protein kinase C, neutral sphingomyelinase, and c-Raf-1 protein kinase among others. Phosphatidylserine is externalized during apoptosis by scramblases in the plasma membrane as a signal for phagocytes to engulf the cell. Phosphatidylserines (bovine) is a mixture of bovine phosphatidylserines containing fatty acids with variable chain lengths at the sn-1 and sn-2 positions.

Deapioplatycodin D and platycodin D can regulate the production and secretion of airway mucin and, at least in part, explains the traditional use of aqueous extract of APG as expectorants in diverse inflammatory pulmonary diseases. Deapi-platycodin D has anti-inflammatory activity.

1. Prunetin (Prunusetin) significantly reduces serum levels of inflammatory cytokines and mortality in mice challenged with lipopolysaccharide. 2. Prunetin mediates anti-obesity adipogenesis effects by suppressing obesity-related transcription through a feedback mechanism that regulates the expression of adiponectin, adipoR1, adipoR2, and AMPK. 3. Prunetin and biochanin A are potent reducers of NF-κB and ERK activation, zonula occludens 1 tyrosine phosphorylation, and metalloproteinase-mediated shedding activity, which may account for the barrier-improving ability of these isoflavones. 4. Prunetin significantly suppresses ATP-induced mucin secretion from cultured RTSE cells; Prunetin inhibits the production of MUC5AC mucin protein induced by EGF or PMA from NCI-H292 cells; Prunetin also inhibits the expression of MUC5AC mucin gene induced by EGF or PMA from NCI-H292 cells.

11-Deoxyprostaglandin F2β (11-deoxy PGF2β), an analog of PGF2β, is derived through the cyclooxygenase metabolism of arachidonic acid. PGF2β is known to prompt a dose-dependent secretion of hexose-containing mucin [1] [2] [3].
