Novel derivatives of some non steroidal anti-inflammatory drugs, as well as of the antioxidants α-lipoic acid, trolox and (E)-3-(3,5-di-tert-butyl-4-hydroxyphenyl)acrylic acid with lorazepam were synthesised by a straightforward method at satisfactory to high yields (40%–93%). All the tested derivatives strongly decreased lipidemic indices in rat plasma after Triton induced hyperlipidaemia. They also reduced acute inflammation and a number of them demonstrated lipoxygenase inhibitory activity. Those compounds acquiring antioxidant moiety were inhibitors of lipid peroxidation and radical scavengers. Therefore, the synthesised compounds may add to the current knowledge about multifunctional agents acting against various disorders implicating inflammation, dyslipidaemia and oxidative stress.

Aspirin is unique among the nonsteroidal anti-inflammatory drugs in that it has both anti-inflammatory as well as cardio-protective properties. The cardio-protective properties arise form its judicious inhibition of platelet-derived thromboxane A2over prostacyclin, while its anti-inflammatory effects of aspirin stem from its well-established inhibition of prostaglandin (PG) synthesis within inflamed tissues. Thus aspirin and the other NSAIDs have popularised the notion of inhibiting PG biosynthesis as a common anti-inflammatory strategy based on the erroneous premise that all eicosanoids are generally detrimental to inflammation. However, our fascination with aspirin has shown a more affable side to lipid mediators based on our increasing interest in the endogenous control of acute inflammation and in factors that mediate its resolution. Epi-lipoxins (epi-LXs), for instance, are produced from aspirin’s acetylation of inducible cyclooxygenase 2 (COX-2) and together with Resolvins represent an increasingly important family of immuno-regulatory and potentially cardio-protective lipid mediators. Aspirin is beginning to teach us what nature knew all along – that not all lipid mediators are bad. It seems that while some eicosanoids are pathogenic in a variety of diseases, others are unarguable protective. In this review we will re-count aspirin’s colorful history, discuss its traditional mode of action and the controversies associated therewith, as well as highlight some of the new pathways in inflammation and the cardiovascular systems that aspirin has recently revealed.

The search for new analgesic and anti-inflammatory drugs, exceeding by efficacy and/or safety the existing<br />analogues is very important and relevant. The nitrogenous heterocycles are promising in this respect, in particular,<br />the compounds containing an imidazole triazol and tіadiazin moiety. The aim of the current study was to investigate<br />the antiexudative and antinociceptive activity of new derivatives of 5,7-diacyl-3-H(alkyl)-6-aryl-5H[1,2,4]triazol[3,4-b]<br />[1,3,4]thiadiazine.<br />The antinociceptive and antiexudative activity studies were carried out on the white nonlinear mice. The<br />experimental evaluation of specific activity was carried out on the models “Hot plate”, acetic acid induced writhing<br />(antinociceptive action) and carrageenan edema (antiexudative action). The substance was used in a single oral rout<br />administration in a dose of 25 mg/kg. Ketorolac was used as a reference product in the dose of 25 mg/kg (models<br />“Hot plate”, acetic acid induced writhing). Diclofenac was used as a reference product in the dose of 25 mg/kg on<br />the model carrageenan edema. The experimental study showed the antinociceptive and antiexudative effects of the<br />derivatives. The antinociceptive activity of 5,7-diacyl-3-H(alkіl)-6-aryl-5H[1,2,4]triazol[3,4-b][1,3,4]tіadiazin derivaties<br />related to the modification structure in the para position of benzene ring. The antiexudative activity is associated with<br />acetyl groups thiadiazine ring. The most promising compound IFT_247 showed a significant antinociceptive effect,<br />which is comparable to an active comparator ketorolac: “Hot plate” +232.46 % and +112.71 %; acetic acid induced<br />writhing -66.67 % and -61.02 %, respectively.
