staurosporine/edema

Protein kinase C (PKC) mediates a number of intracellular signal transduction pathways implicated in the pathogenesis of inflammation, including phospholipase A2-dependent arachidonic acid release and eicosanoid production. Recent studies demonstrate that the PKC inhibitor GF109203X significantly

Recruitment of inflammatory cells to the lung capillaries has been proposed as an important step in the sequence of events that lead to acute lung injury. Frequently, in the clinical setting, bacteremia and sepsis syndrome precede the acute lung failure and endotoxin priming may represent a

The tumor promoters 12-O-tetradecanoyl-phorbol-13-acetate (TPA), a strong activator of protein kinase C (PKC) and okadaic acid, which is ineffective in this respect, induce a rapidly developing ('early') edema of the mouse ear. Bryostatin, another potent activator of PKC, is unable to induce an

The effect of staurosporine on 7,12-dimethylbenz[a]anthracene (DMBA)-initiated and 12-O-tetradecanoylphorbol-13-acetate (TPA)-promoted skin papilloma formation was examined in CD-1 mice. A topical application of staurosporine 15 min prior to each TPA treatment resulted in a dose-related inhibition

Edema fluid (EF) increases epithelial Na(+) transport by rat fetal distal lung epithelia (FDLE) and induces net lung fluid absorption in fetal mouse lung explants [Rafii B, Gillie DJ, Sulowski C, Hannam V, Cheung T, Otulakowski G, Barker PM, O'Brodovich H. J Physiol (Lond) 544: 537-548, 2002]. We

We examined the mechanisms of norathyriol on the serotonin-induced increased permeability of rat heart endothelial cell monolayers. The present study showed that the activation of rat heart endothelial cell protein kinase C by phorbol myristate acetate led to the dose-dependent increase in

The integrity of endothelial cell monolayers, a critical requirement for barrier maintenance, is needed for the prevention of edema formation. To investigate the mechanisms by which 2-phenyl-4-quinolone (YT-1) provided protection against serotonin-induced exudation, rat heart endothelial cell

The sphingosine analog L-threo-dihydrosphingosine has been shown to inhibit protein kinase C (PKC) isoenzymes in mixed micelle and vesicle assays. This compound also inhibited the reactive oxygen intermediates (ROI) released from isolated neutrophils (IC50 approximately 2 microM) and phorbol

The seeds of Lepidium apetalum Willdenow (called "Tinglizi" in China and "Jungryukza" in Korea) have been used to discharge phlegm and improve dropsy in Oriental medicine. The present study investigated the effects of ethanol extract of the seeds of Lepidium apetalum (ELA) on atrial dynamics and

BACKGROUND Spinal cord injury is nowadays still a challenging disease, and a treatment option aimed at the primary site of injury does not currently exist. Therefore, the management of acute spinal cord injury has recently focused on the reasons behind the aggravation of the initial insult through

The importance of endothelial contraction in the genesis of inflammatory edema has been reported. ROS are metabolites synthesized in pathological conditions in that a significant intravascular fluid leak occurs, such as ischemia-reperfusion. Present experiments were designed to test the hypothesis

The protein kinase inhibitor staurosporine has been used to design a series of selective bisindolylmaleimide inhibitors of protein kinase C (PKC). Guided by molecular graphics, conformational restriction of the cationic side chain has led to ATP competitive inhibitors of improved potency and

The inhibitory effects of three novel staurosporine-derived compounds were tested with five different types of protein kinases, including protein kinase C (PKC). IC50 values of two of these compounds were found to be 300 to > 5000 times lower for PKC alpha beta gamma (a mixture of the PKC isoenzymes

Euphorbia kansui is a commonly used traditional Chinese medicine for the treatment of edema, pleural effusion, and asthma, etc. According to the previous researches, terpenoids in E. kansui possess various biological activities, e.g., anti-virus, anti-allergy, antitumor effects. In this work, twenty

In vivo studies have indicated that systemically administered bilobalide, a sesquiterpene trilactone constituent of Ginkgo biloba leaf extracts, can reduce cerebral edema produced by triethyltin, decrease cortical infarct volume in certain stroke models, and reduce cerebral ischemia. In vitro and ex
