Recent studies of nitrogen containing heterocyclic compounds as novel antiviral agents: A review.

N-heterocycles are important, not only because of their abundance, but above all because of their chemical, biological and technical significance. They play an important role in biological investigation such as anticancer, antiinflammatory, antibacterial, antiviral, anti-tumor, antidiabetic, etc. In this study, we focused on examining synthesized some 5- or 6-ring N-heterocyclic compounds that showed the antiviral activity in last 5 years, and investigation of these compounds structure-activity relationship studies.

Synthesis of novel Schiff bases and azol-β-lactam derivatives starting from morpholine and thiomorpholine and investigation of their antitubercular, antiurease activity, acethylcolinesterase inhibition effect and antioxidant capacity.

In this study, new Schiff bases and β-lactam derivatives containing morpholine and thio morpholine nuclei were synthesized. Antimicrobial, antioxidant, antimicrobial and antioxidant properties of all synthesized compounds were investigated and highly effective products were obtained. In this context, new effective structures were introduced to the literature.

Conventional and microwave prompted synthesis, antioxidant, anticholinesterase activity screening and molecular docking studies of new quinolone-triazole hybrids.

The synthesis of ethyl 4-oxo-1,4-dihydroquinoline-3-carboxylates (4, 5) was performed via the reaction of corresponding anilines with diethyl ethoxymethylenemalonate under conventional and also microwave promoted conditions. The treatment of 4 and 5 afforded the corresponding hydrazides (6 and 7). These hydrazides were converted to the corresponding carbo(thio)amides (9a-f and 10a-e) which were then subjected to an intramolecular cyclisation leading to the formation of quinolone-triazole hybrids (11a-f and 12a-e).
