Abstract
The studing of anti-inflammatory activity of the novel compounds may give rise to the using of safer and more active drugs in the treatment of diseases which are shown NSAIDs. To further study the pharmacological properties of the synthesized c compounds were studied for acute toxicity and anti-inflammatory activity of 5-thio derivates of 3-(5-вromofuran-2-yl)-4-ethyl-(4H)-1,2,4-triazole at white rats by formalin method of acute edema. After investigation of anti-inflammatory activity in vivo of first synthesized 1,2,4-triazole derivatives it was found that potassium salt of 2-(4-ethyl-5-(5-bromfuran-2-yl)-1,2,4-triazoles 3-iltio) acetic acid (Compound 24) had the most significant anti-inflammatory activity. This compound suppressed the formation of edema quotes of rats at 59.87% and was more active than the reference drug diclofenac at 15.13%. There were established the patterns regarding chemical structure and pharmacological action of these substances. So replacing of bromine atom at the dimethylamino group in the para-position of the phenyl radical in the molecule of N'-(4-brombenzyliden)-2-((5-(5-bromfuran-2-yl)-4-ethyl-4H-1,2,4-triazole-3-yl)tio)acetic hydrazid (Compound 36) was accompanied by appearence of the anti-inflammatory action. It was revealed that in the number from the ammonium salt (Compound 30) to monoethanolamonium salt (Compound 23) and to the morpholinum salt (Compound 22) it was observed an increase of inflammation and probably growing number of pro-inflammatory mediators released.
