Benzothiazole a privileged scaffold for Cutting-Edges anticancer agents: Exploring drug design, structure-activity relationship, and docking studies. Eur J Med Chem 2024; 279:116831.

Abstract
Cancer is a major societal, public health, and economic burden in the 21st century, with 9.7 million deaths in 2022 (9.96 million in 2020) and 20 million new cancer cases (19.6 million in 2020). Considering the increasing number of cancer cases and deaths, heterocyclic compounds always paved the gold mine for the development of potential anticancer drugs as these compounds have unique flexibility and dynamic cores. Benzothiazoles and their derivatives have potential anticancer properties, making them a desirable scaffold among different heterocycles. Title structures are a class of chemicals that may bind to various receptors with high affinity, particularly those engaged in oncogenic processes. The use of these compounds allows medicinal chemists to rapidly produce anticancer treatments across a large range of targets over an extended length of time. The current study presents a thorough success story of benzothiazole derivatives as anticancer agents. It discusses the current state of cancer, the profile of benzothiazole-based derivatives synthetic pathways, and its relevance as an anticancer agent on several oncogenic pathways. The structure-activity relationship was also added to offer insight into the connection of biological data with structure and the rational design of more active drugs.

Abstract
A novel series of s-triazine linked benzothiazole and coumarin hybrids (6a-6d, 7a-7d, and 8a-8d) were synthesized and characterized by IR, NMR, and mass spectrometry. The compound's in vitro antibacterial and antimycobacterial activities were also evaluated. Remarkable antibacterial activity with MIC in the range of 12.5-62.5 μM and antifungal activity of 100-200 μM were demonstrated by in vitro antimicrobial analysis. Compounds 6b, 6d, 7b, 7d, and 8a strongly inhibited all bacterial strains, while 6b, 6c, and 7d had good to moderate efficacy against M. tuberculosis H37Rv. Synthesized hybrids are observed in the active pocket of the S. aureus dihydropteroate synthetase enzyme, according to a molecular docking investigations. Among the docked compounds, 6d had a strong interaction and a greater binding affinity, and the dynamic stability of protein-ligand complexes was examined using molecular dynamic simulation with various settings at 100 ns. The proposed compounds successfully maintained their molecular interaction and structural integrity inside the S. aureus dihydropteroate synthase, according to the MD simulation analysis. These in silico analyses supported the in vitro antibacterial results of compound 6d, which demonstrated outstanding in vitro antibacterial efficacy against all bacterial strains. In the quest for new antibacterial drug-like molecules, compounds 6d, 7b, and 8a have been identified as promising lead compounds.Communicated by Ramaswamy H. Sarma.

Abstract
Antimicrobial resistance (AMR) is a worldwide concern among infectious diseases due to increased mortality, morbidity and treatment cost. According to WHO 2019 report, among the 32 antibiotics in the clinical trials, only six were classified as innovative and containing novel moiety. The remaining antibiotics from this list contain previously known moiety (WHO AMR 2019). Therefore, the development of novel antibiotics to control resistance problems is crucial. Benzothiazole derivatives are of great interest due to their wide range of biological activities and medicinal applications. Reported data indicated that benzothiazole derivatives displayed antibacterial activity by inhibiting the dihydroorotase, DNA gyrase, uridine diphosphate-n-acetyl enol pyruvyl glucosamine reductase (MurB), peptide deformylase, aldose reductase, casdihydrofolate reductase, enoyl acyl carrier protein reductase, dialkylglycine decarboxylase, dehydrosqualene synthase, dihydropteroate synthase and tyrosine kinase. The present review analyzed the synthesis, structure-activity relationship (SAR) and mechanism of action studies of benzothiazole derivatives as antibacterial agents reported by various research groups in the last five years (2018-2022). Different patents on the antimicrobial activity of benzothiazole derivatives have also been summarized. The finding of the present review will be beneficial for the researchers in the development of novel antibacterial molecules based on benzothiazole moiety. Graphical Abstract

Abstract
The benzazoles are very important entities having immense biological activities, hence; the synthesis of benzazoles is one of the prime areas for synthetic chemists. In pursuit of sustainable protocol, herein an oxidative enzyme i.e. catalase mediated sustainable synthesis is presented. Catalase is a metalloenzyme which is essential for the breakdown of toxic hydrogen peroxide into water and oxygen inside the cell. Despite the higher activity and turnover number of catalase inside the cell, its activity outside the cell is unexplored. Therefore, to explore the hidden potential of catalase for catalyzing the organic transformations, here we reported a green and efficient method for synthesis of benzazoles by the cyclocondensation of o-aminothiophenol or o-phenylenediammine and various aryl aldehydes with ensuing dehydrogenation. This protocol is greener, sustainable and rapid with excellent yields of the products and in addition to this, the catalase demonstrates good functional group tolerance.

A metal-organic framework [MIL-101(Cr)] was used as an efficient heterogeneous catalyst in the synthesis of benzoazoles (benzimidazole, benzothiazole, and benzoxazole), and quantitative conversion of products were obtained under optimized reaction conditions. The catalyst could be simply extracted from the reaction mixture, providing an efficient and clean synthetic methodology for the synthesis of benzoazoles. The MIL-101(Cr) catalyst could be reused without a remarkable decrease in its catalytic efficiency.

Abstract
2-Arylbenzazoles are promising molecules for potential applications in medicine and material areas. Efficient protocols for direct regioselective functionalization of 2-arylbenzoxazoles are in high demand. Herein, we disclose a general method for selective ortho-olefination of 2-arylbenzo[d]oxazoles with alkenes enabled by versatile Cp*Rh(III) in high yields. This protocol features broad functional group tolerance and high regioselectivity. Intermolecular competition studies and kinetic isotope effect experiments imply that the oxidative olefination process occurs via an electrophilic C-H activation pathway. The molecular structure of the m-fluoro-substituted olefination product confirms regioselective C-H activation/olefination at the more hindered site in cases where the meta F atom or heteroatom substituent existed. Apparent torsion angles were observed in the structures of mono- and bis-olefination products, which resulted in distinct different chemical shifts of olefinic protons. Additionally, two gram-scale reactions and further transformation experiments demonstrate that this method is practical for synthesis of ortho-alkenylated 2-arylbenzoxazole derivatives.

Abstract
Benzothiazole is a privileged heterocyclic scaffold having a benzene ring fused with a five-membered thiazole ring. This moiety has attracted considerable attention because of its wide range of pharmacological activities such as antitubercular, antimicrobial, antimalarial, anticonvulsant, anthelmintic, analgesic, anti-inflammatory, antidiabetic, antitumor activity, etc. In the last few years, some novel benzothiazoles have been developed with varied biological activities. To access this scaffold in high yield and to introduce diversity, a variety of new synthetic methods have been invented. In this review, we highlight the development of novel benzothiazoles for various biological activities along with the best synthetic protocols for their synthesis.
