Thiazole heterocycles have attracted significant attention as versatile scaffolds for the development of novel anti-inflammatory agents. Their structural diversity, ease of functionalization, and ability to interact with multiple molecular targets make them particularly attractive for addressing complex inflammatory pathologies. This review provides a comprehensive and strategic overview of thiazole-based anti-inflammatory compounds, highlighting structural classes, and mechanistic insights. Particular emphasis is placed on multi-target approaches that combine anti-inflammatory and antioxidant properties, as well as the design of prodrug and hybrid molecules aimed at improving pharmacokinetic profiles. Despite promising preclinical data, translational challenges remain, including limited in vivo validation, variability in experimental models, and gaps in ADME/toxicity profiling

Condensed bicyclic systems with 1,3,4-thiadiazole core being annulated to pyridine or pyrimidine ones occupy prominent place in medicinal chemistry because of their broad spectrum of pharmacological properties. The combination of these heterocyclic systems into a bicyclic scaffold commonly provides much more interest in the enhanced activity profile of its analogs than their parent monocyclic constituents. Thus, a number of pyridines or pyrimidines fused to thiadiazoles are incorporated into a wide variety of therapeutically important compounds possessing a broad spectrum of biological activities. In the present review we highlight recent advances in the fast-growing research area of thiadiazolo[3,2-a]pyridines and thiadiazolo[3,2-a]pyrimidines chemistry summarizing the existing literature information with respect of their synthetic approaches. Considering such a significant pharmacological potential, as well as wide synthetic possibilities, mentioned fused heterosystems have received considerable attention from scientific community as perspective scaffold for the rational design of drug-likes candidates.

Triazolo[3,4-b][1,3,4]thiadiazole molecules are found to be important tools in modern bioorganic and medicinal chemistry. This condensed system successfully combines two pharmacologically significant five-membered heterocycles – 1,2,4-triazole and 1,3,4-thiadiazole, which causes much more interest in the enhanced activity profile of its analogs than their parent separate constituents. It’s considered that the triazoles fused to thiadiazoles exhibit various therapeutically important properties, probably due to the existence of N-C-S fragments in their structures. In this review, we presented the summarized literature data about the diversity of pharmacological effects of [1,2,4]triazolo[3,4-b][1,3,4]thiadiazole based compounds as promising objects for the rational design of drug-like molecules.

In the present work, we report an efficient synthesis and antioxidant activity evaluation of some 4-arylimino-thiazolidin-2-ones. The structures of target substances were confirmed through ¹H and ¹³C NMR spectroscopy, mass spectrometry and elemental analysis. The antioxidant activity of the synthesized compounds was measured in vitro by the method of scavenging effect on 2,2-diphenyl-1-picrylhydrazyl (DPPH) radicals. Notably, antioxidant activity was identified for the first time among 4-arylimino-thiazolidin-2-ones.

Triazolo[3,4-b]thiadiazoles are a class of heterocyclic compounds, which have attracted great interest in medicinal chemistry owing to their wide range of pharmacological activities. A number of triazoles fused to thiadiazoles are incorporated into a wide variety of therapeutically important compounds possessing a broad spectrum of biological activities. Considering such a significant pharmacological potential, as well as wide synthetic possibilities triazolo-thiadiazoles have received considerable attention from scientific community and are extensively used for construction of prospective drug-likes molecules. In this review, we summarized the literature data about the main synthetic approaches for obtaining condensed heterocyclic compounds based on triazolo[3,4-b][1,3,4]thiadiazole scaffold as promising objects for modern bioorganic and medicinal chemistry.

A crucial direction in the progress of modern medical chemistry is the development and improvement of theoretical investigation methods of drugs mechanisms of action, predicting their activity, and virtual design of new drugs. This review describes the history of targeted search for biologically active compounds, current in silico approaches and tools used in the rational design of potential drugs, in particular the main computational strategies used in modern drug design are presented and outlines the main methodologies for implementing these strategies.

In the present work, we presented an efficient synthesis and anticancer activity evaluation of some new 3-R-6-(5-arylfuran-2-yl-[1,2,4]triazolo[3,4-b][1,3,4]thiadiazoles. We have shown that the proposed synthetic protocols provided the possibility to design triazolothiadiazoles diversity with a considerable chemical novelty. The structures of target substances were confirmed by using 1H NMR spectroscopy, mass spectrometry and elemental analysis. The synthesized compounds were selected by the National Cancer Institute Developmental Therapeutic Program for the in vitro cell line screening. Among all the substances tested, three compounds exhibited significant cytotoxic activity.

Spodopetra Frugiperda is a highly polyphagous migratory lepidopteran pest species. It causes infestation in crops leading to severe crop losses. Being a new invasive parasite, its susceptibility to insecticides needs to be explored and therefore, there is an urgent need to develop the potent insecticides for the effective control of this insect pest. This is the first report on toxic effects produced by the prepared chalcone and hydrazone analogs, followed by structure relationships. Five compounds of chalcone and hydrazone derivatives have been synthesized in pure state as reported procedures, and their toxicity as potential insecticidal agent against Spodopetra Frugiperda was screened. Their characterizations by using spectroscopic analyses were performed. The toxicity data exhibited that compound 5 is more toxic about 2-fold than other synthesized compounds, the other screened compounds showed weak to strong toxicological activity against Spodopetra Frugiperda (lepidoptera: Noctuidae).
