Efficient approach to thiazolidinones via a one-pot three-component reaction involving 2-amino-1-phenylethanone hydrochloride, aldehyde and mercaptoacetic acid

A highly efficient three-component reaction has been developed for the synthesis of thiazolidinones involving the reaction of 2-amino-1-phenylethanone hydrochloride with an aromatic aldehyde and mercaptoacetic acid in the presence of diisopropylethylamine in a single pot. Critically, this reaction exhibited excellent chemoselectivity, with the nitrogen atom of the 2-amino-1-phenylethanone component reacting selectively with the aromatic aldehyde to give the corresponding Schiff base. Nucleophilic attack at the carbon of the Schiff base by the sulfur atom of mercaptoacetic, followed by a cyclocondensation reaction between the nitrogen and the carboxylic acid moiety afforded the desired thiazolidinones, which were fully characterized by spectroscopic techniques.

A retrospect study on thiazole derivatives as the potential antidiabetic agents in drug discovery and developments

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.

Morpholine as a privileged structure: A review on the medicinal chemistry and pharmacological activity of morpholine containing bioactive molecules

Morpholine is a heterocycle featured in numerous approved and experimental drugs as well as bioactive molecules. It is often employed in the field of medicinal chemistry for its advantageous physicochemical, biological, and metabolic properties, as well as its facile synthetic routes. The morpholine ring is a versatile and readily accessible synthetic building block, it is easily introduced as an amine reagent or can be built according to a variety of available synthetic methodologies. This versatile scaffold, appropriately substituted, possesses a wide range of biological activities. There are many examples of molecular targets of morpholine bioactive in which the significant contribution of the morpholine moiety has been demonstrated; it is an integral component of the pharmacophore for certain enzyme active-site inhibitors whereas it bestows selective affinity for a wide range of receptors. A large body of in vivo studies has demonstrated morpholine’s potential to not only increase potency but also provide compounds with desirable drug-like properties and improved pharamacokinetics. In this review we describe the medicinal chemistry/pharmacological activity of morpholine derivatives on various therapeutically related molecular targets, attempting to highlight the importance of the morpholine ring in drug design and development as well as to justify its classification as a privileged structure.

Functional chemical groups that may likely become a source for the synthesis of novel central nervous system (CNS) acting drugs

Introduction: Central Nervous System (CNS) disorders are on increase perhaps due to genetic, enviromental, social and dietetic factors. Unfortunately, a large number of CNS drugs have adverse effects such as addiction, tolerance, psychological and physical dependence. In view of this, literature search was carried out with a view to identify functional chemical groups that may serve as lead molecules for synthesis of compounds that may have CNS activity. Methods: The search revealed that heterocycles that have heteroatoms such as nitrogen (N), sulphur (S) and oxygen (O) form the largest class of organic compounds. They replace carbon in a benzene ring to form pyridine. Compounds with furan, thiophene, pyrrole, pyridine, azole, imidazole, indole, purine, pyrimidine, esters, carboxylic acid, aldehyde, pyrylium, pyrone, pyrodine, barbituric acid, barbiturate, quinoline, quinolone, isoquinolone, coumarin, alkylpyridine, picoline, piperidine, diazine, carboxamide, flavonoid glycoside, oxindole, aminophenol, benzimidazole, benzoxazole, benzothiazole, and chromone chemical groups among others may have CNS effects ranging from depression passing through euphoria to convulsion. Results and Conclusion: Examples of the compounds with the functional groups include but not limited to coal tar, pyridostigmine, pralidoxime, quinine, mefloquine, pyrilamine, pyronaridine, ciprofloxacin and piroxicam. A number of them can undergo keto-enol tautomerism. Chiral amines may be used for derivation of chiral carboxylic acids which are components of tautomers. Some tautomers may cause parkinsonism and Stevens Johnson syndrome.
