The article presents a modified method for the synthesis of 2-substituted 5,6,7,8-tetrahydrobenzo[4,5]thieno[2,3-d]pyrimidine-4(3H)-one and the predict of their anti-inflammatory activity. The proposed method for obtaining tetrahydrothienopyrimidine derivatives is preparatively effective and simple. Their synthesis was carried out by heterocyclization of azomethine derivatives of 2-amino-4,5,6,7-tetrahydro-1-benzothiophene-3-carboxamide in the medium of glacial acetic acid with the catalytic addition of dimethyl sulfoxide. Preliminary prognosis of anti-inflammatory activity in silico method allowed us to identify the most promising compounds. Of these, the 4b structure containing a 2-hydroxyphenyl fragment in the second position of pyrimidine-4(3H)-one may be of the greatest interest. It seems appropriate to further study the spectrum of biological activity of the studied compounds.

Objective: The objective of this search was to synthesize a new naproxen analogues having a 1,2,4-triazole-3-thiol heterocyclic ring, and preliminary pharmacological assessment of the anti-inflammatory activity of the synthesized compounds. Methods: The synthesis of naproxen analogues that having 1,2,4-triazole-3-thiol heterocyclic ring occur through esterification of naproxen, and then its reaction with hydrazine hydrate, and carbon disulfide, finally different aromatic aldehydes reacted with triazole derivatives of naproxen containing amino group to produce schiff bases.Results: In vivo acute anti-inflammatory activity of the synthesize compounds (Va-Vd) was evaluated in rats using egg-white induced edema model of inflammation in a dose equivalent to (50 mg/kg) of naproxen. All tested compounds were produced a significant reduction in paw edema with respect to the effect of propylene glycol 50% v/v (control group). Compound Vd produced superior anti-inflammatory activity compared to naproxen.Conclusion: The results obtained in this work give evidence about the valid synthesis of 1,2,4 triazole-3-thiol derivatives of naproxen, which reacted with different aldehydes to yield several schiff bases. The incorporation of benzaldehyde possess para-electron donating group (para-hydroxyl benzaldehyde) will increase the anti-inflammatory activity of naproxen.

Benzoxazoles being structurally similar to bases adenine and guanine interact with biomolecules present in living systems. These compounds possess antimicrobial, central nervous system activities, antihyperglycemic potentiating activity, analgesic, and anti-inflammatory activity. It can also be used as starting material for other bioactive molecules. Modifications in structure and the biological profiles of new generations of benzoxazoles were found to be more potent with enhanced biological activity. Considering all these, we have prepared this review and discussed the synthesis and biological activities of benzoxazoles.

The pyrazoline ring is a ubiquitous structural feature of many natural and synthetic compounds with potent anti-inflammatory activity. The creation of novel pyrazoline derivatives and examination of their chemical and biological behaviour have gained additional focus in the current decade. Pyrazolines and its fused heterocyclic derivatives tested with anti-inflammatory activity constitute a significant class of compounds for novel drug evolution. Pyrazoline nucleus when linked with different substituents like alkyl, aromatic, heterocyclic rings and many other groups at different positions on the ring shows considerable to more effective anti-inflammatory activity. This article presents a comprehensive review of the anti-inflammatory activity of some novel derivatives of pyrazoline ring.

The chemical study of Laennecia schiedeana afforded three sterols, five diterpenes, five flavonoids, three caffeoyl derivatives of quinic acid, and two triterpenes. Evaluation of the cytotoxic activity of the extracts and isolated metabolites showed that 15-methoxy-16-oxo- 15,16H-strictic acid was the most active compound [(15.05 ± 2.2) μg/mL against U-251 cells]. In antibacterial assays the acetonic extract of leaves was the only active extract exhibiting its highest effect against the multiresistant Staphylococcus epidermidis (MIC 0.25 mg/mL). The anti-inflammatory activity observed was mild in the extracts and not relevant in the isolated compounds
