The ability of the second generation phosphodiesterase 4 inhibitor SB 207499 (Ariflo), [c-4-cyano-4-(3-cyclopentyloxy-4-methoxyphenyl)-r-l-cyclohexane carboxylic acid], to inhibit inflammatory cytokine production in vivo was evaluated and compared to that of rolipram, a first generation
Preclinical studies on toxicology and pharmacokinetics were performed for (1,1-bis(aminomethyl)cyclohexane)oxalatoplatinum(II) (TNO-38) in rats and a dog after LD10 and LD50 assessment in mice. In drug-treated rats, ura and creatinine concentrations were 1.4-1.9 times those in control rats.
A series of platinum compounds with an analogue structure to cisplatin have been synthesized and their biological activity against HL-60 cancer cell line has been studied. The interaction with DNA was evaluated by circular dichroism (CD), electrophoresis and atomic force microscopy (AFM) techniques
1. Nitric oxide (NO) participates, at least in part, to the establishment and maintenance of pain after nerve injury. Therefore, drugs that target the NO/cGMP signaling pathway are of interest for the treatment of human neuropathic pain. Various compounds endowed with NO-releasing properties
Although a promising strategy, the mesenchymal stem cell (MSC)-based therapy of cartilage defects is sometimes accompanied with chronic inflammation during the remodeling status, which may hinder cartilage regeneration. During this process, the inflammatory cytokine tumor necrosis factor α (TNFα)
4-Vinyl-1-cyclohexene diepoxide is used a chemical intermediate and as a reactive diluent for diepoxides and epoxy resins. Toxicology and carcinogenesis studies were conducted by administering 4-vinyl-1-cyclohexene diepoxide (97% pure) in acetone by dermal application to individually housed F344/N
A case of fatal acute renal failure during treatment with 1,1-diaminomethyl cyclohexane sulphato platinum II (TNO-6) is reported. Pathologic investigation showed focal tubular necrosis with interstitial infiltration and edema. Despite the development of proteinuria no changes of the glomeruli were
The photoprotein aequorin emits light by an intermolecular reaction when mixed with Ca2+. To apply a bioluminescent immunoassay based on the light emission property of aequorin, we prepared aequorin-antibody Fab' conjugates by a chemical cross-linking technique. Recombinant apoaequorin was coupled
β-Elemene (1-methyl-1-vinyl-2,4-diisopropenyl-cyclohexane), a natural sesquiterpene-derived curcumae radix, exhibits a variety of pharmacologic properties including anticancer. However, the molecular action of β-elemene in chemical-induced skin carcinogenesis remains unclear. Therefore, the present
Crotepoxide (a substituted cyclohexane diepoxide), isolated from Kaempferia pulchra (peacock ginger), although linked to antitumor and anti-inflammatory activities, the mechanism by which it exhibits these activities, is not yet understood. Because nuclear factor kappaB (NF-kappaB) plays a critical
Human serum albumin (HSA) nanoparticles (NPs) surface modified with tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL) and transferrin, and containing doxorubicin were designed and prepared. Surface amines of HSA were reversibly protected with dimethylmaleic anhydride (DMMA), and
Epidemiology studies have linked mortality, increased asthma morbidity, and other respiratory disorders in urban areas to increases in fine airborne particulate matter (PM) concentrations. However, neither the bioactive components of PM nor the biological mechanisms of the reported health effects
It was previously shown that plasmin activates human peripheral monocytes in terms of lipid mediator release and chemotactic migration. Here it is demonstrated that plasmin induces proinflammatory cytokine release and tissue factor (TF) expression by monocytes. Plasmin 0.043 to 1.43 CTA U/mL, but
AY 9944 [trans-1,4-bis(2-chlorobenzylaminomethyl) cyclohexane dihydrochloride] is an amphiphilic cationic molecule. This chemical is an established inhibitor of cholesterol synthesis and is teratogenic in rats. The mechanisms of this teratogenicity remain to be clarified. This study used cultured
