Abstract
Aim: The objective of the present study was to design, synthesize and evaluate diverse Schiff bases and thiazolidin-4-one derivatives of aminothiazole as key pharmacophores possessing acetylcholinesterase inhibitory activity. Materials & methods: Two series of compounds (13 each) were synthesized and evaluated for their acetylcholinesterase inhibition and antioxidant activity. Molecular docking of all compounds was performed to provide an insight into their binding interactions. Results: Compounds 2j (IC50 = 0.03 μM) and 3e (IC50 = 1.58 μM) were found to be the best acetylcholinesterase inhibitors among compounds of their respective series. Molecular docking analysis supported the results of in vitro activity by displaying good docking scores with the binding pocket of human acetylcholinesterase (Protein Data Bank ID: 4EY7). Conclusion: Compound 2j emerged as a potential lead compound with excellent acetylcholinesterase inhibition, antioxidant and chelation activity.

Abstract
Nowadays, nitrogenous heterocyclic molecules have attracted a great deal of interest among medicinal chemists. Among these potential heterocyclic drugs, benzimidazole scaffolds are considerably prevalent. Due to their isostructural pharmacophore of naturally occurring active biomolecules, benzimidazole derivatives have significant importance as chemotherapeutic agents in diverse clinical conditions. Researchers have synthesized plenty of benzimidazole derivatives in the last decades, amidst a large share of these compounds exerted excellent bioactivity against many ailments with outstanding bioavailability, safety, and stability profiles. In this comprehensive review, we have summarized the bioactivity of the benzimidazole derivatives reported in recent literature (2012-2021) with their available structure-activity relationship. Compounds bearing benzimidazole nucleus possess broad-spectrum pharmacological properties ranging from common antibacterial effects to the world's most virulent diseases. Several promising therapeutic candidates are undergoing human trials, and some of these are going to be approved for clinical use. However, notable challenges, such as drug resistance, costly and tedious synthetic methods, little structural information of receptors, lack of advanced software, and so on, are still viable to be overcome for further research.

Abstract
Amongst sulfur- and nitrogen-containing heterocyclic compounds, the 2-aminothiazole scaffold is one of the characteristic structures in drug development as this essential revelation has several biological activities abiding it to act as an anticancer, antioxidant, antimicrobial and anti-inflammatory agent, among other things. Additionally, various 2-aminothiazole-based derivatives as medical drugs have been broadly used to remedy different kinds of diseases with high therapeutic influence, which has led to their wide innovations. Owing to their wide scale of biological activities, their structural variations have produced attention amongst medicinal chemists. The present review highlights the recently synthesized 2-aminothiazole-containing compounds in the last thirteen years (2008-2020). The originality of this proposal is based on the synthetic strategies developed to access the novel 2-aminothiazole derivatives (N-substituted, 3-substituted, 4-substituted, multi-substituted, aryl/alkyl substituents or acyl/other substituents). The literature reports many synthetic pathways of these 2-aminothiazoles associated with four different biological activities (anticancer, antioxidant, antimicrobial and anti-inflammatory activities). It is wished that this review will be accommodating for new views in the expedition for rationalistic designs of 2-aminothiazole-based medical synthetic pathways.

Abstract
Currently, the development of anticancer drug resistance is significantly restricted the clinical efficacy of the most commonly prescribed anticancer drug. Malignant disease is widely prevalent and considered to be the major challenges of this century, which concerns the medical community all over the world. Consequently, investigating small molecule antitumor agents, which could decrease drug resistance and reduce unpleasant side effect is more desirable. 2-aminothiazole scaffold has emerged as a promising scaffold in medicinal chemistry and drug discovery research. This nucleus is a fundamental part of some clinically applied anticancer drugs such as dasatinib and alpelisib. Literature survey documented that different 2-aminothiazole analogs exhibited their potent and selective nanomolar inhibitory activity against a wide range of human cancerous cell lines such as breast, leukemia, lung, colon, CNS, melanoma, ovarian, renal, and prostate. In this paper, we have reviewed the progresses and structural modification of 2-aminothiazole to pursuit potent anticancers and also highlighted in vitro activities and in silico studies. The information will useful for future innovation. Representatives of 2-aminothiazole-containing compounds classification.

Abstract
Thiazoles have attracted much synthetic interest due to their wide variety of biological properties and are important members of heterocyclic compounds. In recent years, studies on the synthesis of thiazole compounds have been increasing because of the properties of this core. In particular, the hybrid structures in which the thiazole ring and the other nuclei are linked have gained popularity. Hybrid structures are formed by the combination of different groups of chemical reactivity and biological activity characteristics. In this review, we highlight recent developments related to hybrid structures containing a thiazole core, recently developed as anticancer, antibacterial, anti-inflammatory, analgesic, anti-tubercular, antialzheimer and antidiabetic compounds.

Abstract
Abstract
Objectives:
Cancer is one of the leading causes of death throughout the world. Current therapy options suffer from the major limitations of side effects and drug resistance. Thus, continuing search for newer and safer anticancer drugs remains critically important. From this point of view, in the present study benzimidazole-hydrazone derivatives were synthesized by aiming at the identification of new chemical entities as potent anticancer agents.
Material and methods:
A series of 12 new compounds of 4-(5(6)-substituted-1H-benzimidazol-2-yl)-N′thiophen/furan-2-yl-methylene) benzohydrazide derivatives were synthesized. The structures of the obtained compounds were elucidated using by IR, 1H NMR, 13C NMR, mass spectroscopy and elemental analyses. In vitro cytotoxic activity of the compounds against A549, MCF-7 and NIH/3T3 cell lines was evaluated by MTT assay.
Results:
Among the tested compounds, compound 3e showed higher cytotoxicity against MCF-7 human breast cancer cells when compared with cisplatin. Also, it has lower cytotoxicty against healthy cell line, NIH/3T3.
Conclusions:
It was determined that compound 3e showed inhibition towards MCF-7. Considering the substituent effect on cytotoxic activity, compound 3e bearing 2-methylthiophene has attracted attention with its higher anticancer activities.

Abstract
Crystal structures of two benzothiazinones belonging to a class of compounds implicated in antimicrobial, antitumour, and HIV-RT inhibitory activity are reported. The syntheses and crystal structures of 2,3-bis[3-(trifluoromethyl)phenyl]-2,3-dihydro-4H-1,3-benzothiazin-4-one (di-m-CF3; C22H13F6NOS) (1) and 2,3-bis(4-methylphenyl)-2,3-dihydro-4H-1,3-benzothiazin-4-one (di-p-CH3; C22H19NOS) (2) are reported. Each structure is racemic: the asymmetric unit of 2 consists of two molecules. In both 1 and 2, the six-membered 1,3-thiazine ring is close to an envelope conformation with the chiral C atom forming the flap. In 1, the 2-aryl group is pseudo-equatorial, while in 2 it is pseudo-axial. In 1, the pendant aryl rings form a V shape with an inter-centroid distance of 3.938 (3) Å and an acute dihedral angle of 48.3 (2)° between them. Both CF3 groups are disordered over two orientations in 0.687 (19):0.313 (19) and 0.667 (16):0.33 (16) ratios. In each of the independent molecules of 2, the aryl rings are almost orthogonal to each other [dihedral angles = 85.50 (12) and 86.07 (11)°]. In both structures, the chiral C atom and the O atoms participate in C—H⋯O-type hydrogen bonding between symmetry-related molecules of 1 or the independent enantiomers in 2, forming chains along the c-axis direction in 1 and the b-axis direction in 2. Additionally, in 1, π–π contacts of both face-to-face and edge-to-face type, as well as π-H⋯O and π-H⋯F interactions are observed. In 2, a racemic mixture of molecules forms layers in the ac plane linked by weak π–π and C—H⋯π interactions.
