Quaternary benzo[c]phenanthridine alkaloids sanguinarine and chelerythrine have been used in folk medicine for their wide range of useful properties. One of their major effect is also anti-inflammatory activity, that is not clarified in detail. This study focused on the ability of these alkaloids to
A quaternary benzo [c] alkaloid chelerythrine (CHE), which is a traditional herbal prescription, has been used for the treatment of various inflammatory diseases. To gain insight into the anti-inflammatory effect and molecular mechanisms underlying the anti-inflammatory activity of CHE, we used
Chelerythrine (CHE), a quaternary benzo[c]phenanthridine alkaloid, which is an agent in traditional Chinese medicine exhibits a wide spectrum of pharmacological effects. In this study, we examined the anti-inflammatory activities and mechanism of CHE in vivo and in vitro, respectively. Further, in
Chelerythrine (CH), is a kind of benzo[c] phenanthridine alkaloid isolated from plants such as Chelidonium, with pharmacological activities as antitumor, antibiosis and anti-inflammation. However, few studies have demonstrated whether CH could protect against lipopolysaccharide (LPS)-induced acute
Chelerythrine (CHE), a quaternary benzo[c]phenanthridine alkaloid, exhibits a wide spectrum of pharmacological effects. Although CHE has been used to treat various diseases, the protective effects of CHE on lipopolysaccharide (LPS)-induced endotoxic shock have not been explored. The aims of the
The protein kinase C (PKC) is a serine/threonine kinase, consisting of different isoforms, implicated in numerous processes of signal transduction. To understand this enzyme well, different pharmacological tools were developed. To activate PKC specifically, phorbol esters were previously used but
OBJECTIVE
Protein kinase C (PKC) is a key signaling molecule in excitation-contraction coupling in several types of smooth muscle cells. We investigated whether the attenuated contraction in inflamed colon cells is caused by alterations in the expression, distribution, and activation of specific PKC
Polymorphonuclear leukocytes (PMN) play a primary role in the initiation and propagation of inflammatory responses. PMN apoptosis is a major mechanism associated with the resolution of inflammatory reactions. Understanding mechanisms associated with PMN apoptosis will be of critical value in the
1. It has been proposed that the activation of NMDA receptors and upregulation of protein kinase C (PKC) underlie the exaggerated and persistent pain experienced in the inflammatory state. However, there is no direct evidence to show that inflammation alters the function of NMDA receptors. 2. We
To study the glutamatergic mechanisms underlying changes in excitability in the brain stem pain modulatory circuitry after injury, we examined GluR1 serine 831 phosphorylation in the rostral ventromedial medulla (RVM) after complete Freund's adjuvant-induced hindpaw inflammation. Western blots
Natural compounds have been used in the treatment of various diseases for centuries. Herein, we investigated the effects of structurally diverse alkaloids with anti-inflammatory activity (berberine, sanguinarine, chelerythrine, and colchicine) on two important anti-inflammatory and pro-inflammatory
The roles of central protein kinases A and C (PKA and PKC) in various pain states have intensively been investigated during the past decade. The aim of the present study was to investigate the peripheral involvement of PKA and PKC in persistent nociceptive response, evoked pain behaviors, and
A recent study by our group demonstrates pharmacologically that the transient receptor potential vanilloid-1 (TRPV(1)) is activated by intradermal injection of capsaicin to initiate neurogenic inflammation by the release of neuropeptides in the periphery. In this study, expression of TRPV(1),
Chelerythrine (CHE) is a type of benzophenanthridine alkaloid found in many herbs and is also the main alkaloid constituent of Toddalia asiatica (L.) LAM. It has been proven to have various activities including antitumor, antifungal, anti-inflammatory and anti-parasitic effects. We have previously
Chelerythrine is a kind of benzo[c] phenanthridine alkaloids, with such pharmacological activities as antitumor, antibiosis and anti-inflammation, which is widely found in plant of Fumariaceae, Papaveraceae, Ranunculaceae and Rutaceae families. This article summarizes the advances in domestic and
