The title compound, amtolmetin guacil, C(24)H(24)N(2)O(5), is a new gastroprotective non-steroidal anti-inflammatory drug. In the crystal structure, the drug mol-ecule is linked into a one-dimensional structure along the c axis by weak N-H⋯O inter-actions between the amide groups. C-H⋯O and C-H⋯π inter-actions influence the packing.

Currently 2 difference classes of cyclooxygenase (COX)-2 inhibitors, coxibs and relatively selective COX-2 inhibitors, are available for patients requiring nonsteroidal anti-inflammatory drug (NSAID) therapy; their gastroprotective effect is hardly directly compared. The aim of this study was to compare the gastroprotective effect of relatively selective COX-2 inhibitors with coxibs. MEDLINE, E...

Mangiferin (MF), a xanthonoid from Mangifera indica, has been proved to have antisecretory and antioxidant gastroprotective effects against different gastric ulcer models; however, its molecular mechanism has not been previously elucidated. Therefore, the aim of this study was to test its modulatory effect on several signaling pathways using the ischemia/reperfusion model for the first time. An...

Major differences are evident between Japanese and Western practice in the prevention of gastrointestinal injury caused by low-dose aspirin (LDA) and nonsteroidal anti-inflammatory drugs (NSAIDs). The proportion of physicians prescribing gastroprotective agents with NSAIDs and LDA with the aim of preventing gastrointestinal injury is 77% in Japan and between 7084% in Spain, showing the great ma...

BACKGROUND Muntingia calabura L. (family Muntingiaceae), commonly known as Jamaican cherry or kerukup siam in Malaysia, is used traditionally to treat various ailments. The aim of this study is to elucidate the possible underlying gastroprotective mechanisms of ethyl acetate fraction (EAF) of Muntingia calabura methanolic leaves extract (MEMC). METHODS MEMC and its fractions were subjected to...

BACKGROUND Curcuma purpurascens BI. is a medicinal plant from the Zingiberaceae family, which is widely used as a spice and as folk medicine. The aim of the present study is to investigate the gastroprotective activity of C. purpurascens rhizome hexane extract (CPRHE) against ethanol- induced gastric ulcers in rats. METHODS Acute toxicity test was carried out on 36 rats (18 males and 18 femal...

The present study evaluated the antiulcerogenic activity and mechanisms of the aqueous (AqF 100 mg/kg) and ethyl acetate (AcF 50 mg/kg) fractions from Indigofera truxillensis leaves. This dose was selected to assess its activity on ulcer healing and its action on gastric acid and mucus secretion, prostaglandin production and antioxidant enzyme activity (superoxide dismutase (SOD), glutathione...

In search of novel gastroprotective agents, mangiferin, a naturally occurring glucosylxanthone from Mangifera indica L. (Anacardiaceae), was evaluated in mice on gastric injury induced by ethanol and indomethacin. The effects of mangiferin on gastric mucosal damage were assessed by determination of changes in mean gastric lesion area or ulcer score in mice and on gastric secretory volume and to...
