Y-24180 (4-(2-chlorophenyl)-2-[2-(4-isobutylphenyl)ethyl]-6,9-dimethyl-6H-thieno[3,2-f][1,2,4]triazolo[4,3-a][1,4]-diazepine), an antagonist of platelet-activating factor (PAF), has been already clarified to suppress the expression of an adhesion molecule, Mac-1, on human neutrophils in the previous

Acetylcholine α7 nicotinic receptors are widely expressed in the brain, where they are involved in the central processing of pain as well as in neuropsychiatric, neurodegenerative, and inflammatory processes. Positive allosteric modulators (PAMs) show the advantage of allowing the selective

A number of studies reported Mannich bases to manifest antimicrobial, cytotoxic, anticancer, anti-inflammatory, and anticonvulsant activities. A considerable number of therapeutically important cytotoxic compounds are active on DNA topoisomerases that regulate the DNA topology. In the present study

The effect of indomethacin following the concurrent administration of the nitric oxide (NO) synthase inhibitor NG-nitro-L-arginine methyl ester (L-NAME) on acute intestinal microvascular permeability has been investigated in the rat. Administration of indomethacin (10 mg/kg, s.c.) or L-NAME (10

A variety of materials have been used as fillers for soft tissue augmentation. In this study, methylcellulose (MC), a water-soluble derivative of the polysaccharide cellulose, was modified with functional methacrylate groups and photocrosslinked to produce hydrogels for potential application in

Platelet-activating factor (PAF) has been implicated in the pathogenesis of allergic and inflammatory events in the airway. In the present study, we sought to determine if PAF receptors are present on human bronchial epithelial cells and whether PAF binding to these receptors leads to activation of

Collagenase (100 micrograms) induced a large plasma extravasation, during the first 15 min after its injection in rat paw, associated with the rapid development of oedema which subsided after 6 h. The extent of the oedema was similar in normal and kininogen-deficient rats. The swelling induced in

A new simple phloroglucinol derivative characterized as 1-(6-hydroxy-2,4-dimethoxyphenyl)-2-methyl-1-propanone (1) was isolated from Hypericum cistifolium (Hypericaceae) as a major constituent of the non-polar plant extract. Minor amounts of this new compound, in addition to two known structurally
