Background: Heterocycles containing thiazole, a moiety with sulfur and nitrogen is a core structure which is found in a number of biologically active compounds. The thiazole ring is notable as a component of the certain natural products,such as vitamin B1 (thiamine) and penicillins. Thiazole is also known as wonder nucleus and has uses in different biological fields. A number of new compounds contain heterocycle thiazole moieties, thus it is one of the important areas of research. Methods: We searched the scientific database using relevant keywords. Among the searched literature only peer-reviewed papers were collected which addresses our questions. The retrieved quality research articles were screened and analyzed critically. The key findings of these studies were included along with their importance.Results: The quality research articles included in this review were selected for the lifethreatening diseases i.e. diabetes, which is one of the serious issues all over the globe with an estimated worldwide prevalence in 2016 of 422 million people, which is expected to rise double to by 2030. Since 1995, there has been an explosion of the introduction of new classes of pharmacological agents having thiazole moieties. However, most of the drugs can cause noncompliance, hypoglycemia, and obesity. Thus, new antidiabetic drugs with thiazole moieties came up with improved compliance and reduced side effects such as pioglitazone (Actos), rosiglitazone (Avandia), netoglitazone,DRF-2189, PHT46, PMT13, DRF-2519. With such a great importance, research in thiazole is part of many academic and industrial laboratories worldwide.Conclusion: The present review describes the importance of thiazole nucleus and its derivatives as antidiabetic agents with an emphasis on the past as well as recent developments.

Chemical space describes all possible molecules as well as multi-dimensional conceptual spaces representing the structural diversity of these molecules. Part of this chemical space is available in public databases ranging from thousands to billions of compounds. Exploiting these databases for drug discovery represents a typical big data problem limited by computational power, data storage and data access capacity. Here we review recent developments of our laboratory, including progress in the chemical universe databases (GDB) and the fragment subset FDB-17, tools for ligand-based virtual screening by nearest neighbor searches, such as our multi-fingerprint browser for the ZINC database to select purchasable screening compounds, and their application to discover potent and selective inhibitors for calcium channel TRPV6 and Aurora A kinase, the polypharmacology browser (PPB) for predicting off-target effects, and finally interactive 3D-chemical space visualization using our online tools WebDrugCS and WebMolCS. All resources described in this paper are available for public use at www.gdb.unibe.ch.

A two-stage “tandem strategy” for the synthesis of benzofused nitrogen heterocycles is described that is particularly useful for the construction of systems with a high level of substitution on the benzenoid ring. The first stage in the strategy involves a benzannulation based on the reaction of cyclobutenones with ynamides. This cascade process proceeds via a sequence of four pericyclic reactions and furnishes a multiply substituted aniline derivative which can bear a variety of functionalized substituents at the position ortho to the nitrogen. In the second stage of the tandem strategy, ringclosing metathesis generates the nitrogen heterocyclic ring. This two-step sequence provides efficient access to highly substituted dihydroquinolines, benzazepines, benzazocines, and related benzofused nitrogen heterocyclic systems. The application of this chemistry in a concise formal total synthesis of the anticancer agents (?)-FR900482 and (?)-FR66979 is described. 2011 American Chemical Society.

The synthesis, pharmacological evaluation and molecular modelling study of novel naphthalen-2-yl acetate and 1, 6-dithia-4, 9-diazaspiro [4.4]nonane-3, 8-dione derivatives as potential anticonvulsant agents are described. The newly synthesized compounds were characterized by both analytical and spectral data. Alkylation of 1H-imidazole or substituted piperazine with 1-(2-naphthyl)-2-bromoethanone (2) gave naphthalen-2-yl 2-(1H-imidazol-1-yl) acetate (3) and naphthalen-2-yl 2-(substituted piperazin-1-yl) acetate (4?8). Moreover, condensation of naphthalen-2-yl 2-bromoacetate or 2-bromo-1-(naphthalen-2-yl) ethanone with hydrazine hydrate and acetylacetone resulted in the formation of the cyclic pyrazole products 9 and 13. Sonication of naphthalen-2-yl acetate (1) with 2-chloropyridine, 2-chloropyrimidine and 2-(chloromethyl) oxirane gave naphthalen-2-yl 2-(pyridin-2-yl) acetate (10), naphthalen-2-yl 2-(pyrimidin-2-yl) acetate (11) and naphthalen-2-yl-3-(oxiran-2-yl) propanoate (12) respectively. Cyclocondensation reaction of 2-iminothiazolidin-4-one (14) with thioglycolic acid, thiolactic acid and thiomalic acid gave 1, 6-dithia-4, 9-diazaspiro [4.4]nonane-3, 8-dione derivatives (15?17). The compounds were tested in vivo for the anticonvulsant activity by delaying strychnine-induced seizures. The diazaspirononane (17) and 1-(2-naphthyl)-2-bromoethanone (2) showed a high significant delay in the onset of convulsion and prolongation of survival time compared to phenobarbital. The molecular modelling study of anticonvulsant activity of synthesized compounds showed a CNS depressant activity via modulation of benzodiazepine allosteric site in GABA-A receptors.

Background: Cancer has been considered to be a global health concern due to the impact of disease on the quality of life. The continual increase of cancer cases as well as the resistance of cancer cells to the existing drugs have driven the search for novel anticancer drugs with better potency and selectivity, improved pharmacokinetic profiles, and minimum toxicities. Pyridine and pyrimidine are presented in natural products and genetic materials. These pyridine/pyrimidine core structures have been noted for their roles in many biological processes as well as in cancer pathogenesis, which make such compounds become attractive scaffolds for discovery of novel drugs. Results & Conclusion: In the recent years, pyridine- and pyrimidine-based anticancer drugs have been developed based on structural modification of these core structures (i.e., substitution with moieties and rings, conjugation with other compounds, and coordination with metal ions). Detailed discussion is provided in this review to highlight the potential of these small molecules as privileged scaffolds with attractive properties and biological activities for the search of novel anticancer agents.
