چکیده

epoxyquinomicins A, B, C, and D, respectively. Therefore, these epoxyquinomicins are unique candidates for antiinflammatory agents. The modeof action appears to be different from that of common NSAIDs(non-steroidal antiinflammatory drugs)3), since epoxyquinomicins C and D did not inhibit cyclooxygenase-1 at the concentration of 300 /iu. The mechanism of the antiarthritic effect has not been elucidated for epoxyquinomicins. Histidine decarboxylase is considered to be involved in the mechanism of inflammation by producing histamine. Lecanoric acid was isolated from a fungus as a histidine decarboxylase inhibitor4^. A synthetic analogue, SD-170

Deletion of histidine decarboxylase (HDC) enhances the antinociceptive effects of orexin A in the central nervous system

It has long been established that histamine plays a role as a mediator of inflammation. From numerous studies, it has been well known that the amine has many pharmacological actions on a variety of organs. To evaluate the role of histamine in pain perception, we generated HDC knockout mice using a gene targeting method. Histamine is a hydrophilic autacoid, and in most tissues it is stored and s...

Molecular modeling analysis of charge density and heat of fornation by PM3 method as well as C, H NMR and 2D-NMR measurements of histidine (substrate) and some of its derivatives as histidine decarboxylase inhibitors were performed. It was established that the atom, usually nitrogen, which forms internal aldimine with pyridoxal5 -phosphate (PLP), (coenzyme), has negative and almost equal ...

Rat histidine decarboxylase is a substrate for m-calpain in vitro.

We have followed the in vitro degradation of rat histidine decarboxylase in a reconstituted system, containing only rat histidine decarboxylase (obtained by in vitro transcription and translation), calcium ions in the millimolar range of concentrations, and m-calpain. Under the experimental conditions used, m-calpain quickly and efficiently degraded rat histidine decarboxylase, giving rise to a...

Effect of hydrocortisone on histidine decarboxylase activity in rat stomach.

Hydrocortisone-stimulated synthesis of histidine decarboxylase (EC 4.1.1.22) was studied in rat stomach. Single or daily administration of hydrocortisone increased the histidine decarboxylase activity but not the histamine content in the fundic glands of stomachs from fed and fasted rats with or without adrenalectomy, and also in those from adrenalectomized fasted rats with concomitant treatmen...
