Antiedematogenic activity of the indole derivative N-salicyloyltryptamine in animal models
ABSTRACT The N-salicyloyltryptamine (NST) is an indole derivative compound analogue to the alkaloid N-benzoyltryptamine. In the present study, the antiedematogenic activity of NST was investigated in animal models. Firstly, the acute toxicity for NST was assessed according to the OECD Guideline no....

The pretreatment with NST (50, 100 or 200 mg/kg, i.p) attenuates the compound 48/80-induced mast cell degranulation (**p<0.01; ***p<0.001). Thus, the inhibition of both mast cell degranulation and release of endogenous mediators are probably involved in the NST-induced antiedematogenic effect.http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0001-37652018000100185&lng=en&tlng=enAnti-inflammatory agentsedemaindolesinflammation mediatorsN-salicyloyltryptamine |
