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.

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.

The worldwide outbreaks of the chikungunya virus (CHIKV) in the last years demonstrated the need for studies to screen antivirals against CHIKV. The virus was first isolated in Tanzania in 1952 and was responsible for outbreaks in Africa and Southwest Asia in subsequent years. Between 2007 and 2014, some cases were documented in Europe and America. The infection is associated with low rates of death; however, it can progress to a chronic disease characterized by severe arthralgias in infected patients. This infection is also associated with Guillain–Barré syndrome. There is no specific antivirus against CHIKV. Treatment of infected patients is palliative and based on analgesics and non-steroidal anti-inflammatory drugs to reduce arthralgias. Several natural molecules have been described as antiviruses against viruses such as dengue, yellow fever, hepatitis C, and influenza. This review aims to summarize the natural compounds that have demonstrated antiviral activity against chikungunya virus in vitro.

Membered Heterocycle

The development of highly effective and low-toxicity nonsteroidal anti-inflammatory drugs (NSAIDs) is one of the important challenges facing modern pharmacology. To overcome this problem, many studies have been conducted on compounds containing a five-membered heterocycle containing three nitrogen atoms. The pharmacodynamics of these compounds are mainly due to their anti-inflammatory effect. Therefore, it is important to synthesize new derivatives of 1,2,3-triazoles, to determine their structure and to look for substances with anti-inflammatory activity on their basis. For the first time, the corresponding derivatives of 4-(4-(exchangeable)-1H-1,2,3-triazole-1-yl)-benzoic acid were synthesized by cycloaddition of propargyl esters of saturated carboxylic acids and para-azidobenzoic acid in the presence of copper (I) iodide. The structure of the obtained substances was analyzed by IR, 1H NMR, and MS techniques. It is proved that under the action of the catalyst in the reaction, only 1,4-isomers are formed. Factors affecting the course of the reaction were identified. Only one isomer is formed in the reaction of cyclic addition under the action of a catalyst and the effect of temperature, duration of time, and nature of the solvent on the reaction yield was studied.

The synthesis of new selective COX-2 enzyme is an approach for obtaining potent, anti-inflammatory drugs that have fewer side effects. Ketoprofen has a very low selectivity toward COX-2 enzyme and has a serious GIT side effects because it induces gastric ulcer. A new series of 4-thiazolidinones bearing ketoprofen moiety was designed, synthesized, and then evaluated as a new inhibitor of cyclooxygenase-2 (COX-2). Characterization and identification of the synthesized compounds were established by determination of 1H-NMR spectra,13C-NMR spectra, FT-IR spectroscopy, and physical properties. These newly synthesized compounds have been evaluated in vivo for their anti-inflammatory efficiency and in silico selectivity toward COX-2 throughout molecular docking by using GOLD.suite.v.5.6.2. All the tested. compounds via molecular. docking showed significant. activities when compared. With ketoprofen and diclofenac as references drugs, the results were consistent with the study of in in vivo acute. anti-inflammatory activity. Also, ADME studies had been accomplished in order to predict the absorption sites, bioavailability, topological polar surface Area (TPSA), and also drug-likeness. The ADME results reported that. All the synthesized. compounds can be absorbed by the GIT.
