The anti-inflammatory activity of three benzo-pyrones with prevalent lipooxigenase-inhibitory activity was studied using the Croton oil ear test in mice, in comparison with nordihydroguaieretic acid (NDGA) and indomethacin. Kaempferol, quercetin and NOGA possess a strong and prolonged anti-inflammatory effect, whereas the action of indomethacin appears relevant, but not long-lasting. In contrast the anti-inflammatory activity of esculetin is rather weak, but persistent.

2-Benzimidazolylurea (BIU) decreases gastric acid secretion. The antisecretive activity appears to be associated with antihistaminic and antimuscarinic effects.
The antihistaminic activity of BIU appears from its inhibitory effects on betazole stimulated gastric acid secretion and from its inhibitory activity on the isolated guinea pig auricle stimulated by betazole.
The antimuscarinic activity of BIU appears from several experiments: this molecule decreases gastric acid secretion stimulated by carbachol in rats, depresses the neostigmine-stimulated motility of duodenum in the anaesthetized cat, lessens the hypertonus of isolated guinea pig trachea caused by pylocarpine and also inhibits guinea pig ileum activity stimulated by acetylcholine.
BIU probably depresses gastric acid secretion by interferring with both histamine and acetylcholine receptors.

In Wistar rats loaded with SC hypartonic NaCl solution kassinin producos an inhibition of cell-dehydration drinking which lasts soveral hours. The long duration of the effect does not depend on a renal excretion of sodium but, hypothetically, on a redistribution of electrolytes between the extra- and the intra-cellular compartments of body fluids.

Esculetin determined a reduction in oedema and granulocyte infiltration in the Croton oil ear test in vivo. The drug was able to inhibit Acethylcholine-writhing test and showed a LD50 of 1450 mg/kg i.p. and > 2000 mg/kg by mouth. In our experimental conditions, esculetin has an anti-inflammatory and analgesic effect.
