Abstract
Dehydroacetic acid (DHA) was utilized as a fundamental precursor in the synthesis of novel pyrano [4,3-b] pyran and pyrano [2,3-b] pyridine systems. Whereas, a new series of fused polyheteronuclear systems was achieved through the reaction of DHA with active methylene compounds such as malononitrile and pyrazolone. Whereas, the treatment of DHA 1 with cyclic ketones involving cyclohexanone and cyclododecanone afforded annulated tricyclic system 6 and spiro hybrid molecule 7. Also, the reaction of DHA 1 with cyanoacetamide derivatives 8 and 11 yielded their corresponding novel pyrano [2,3-b] pyridine-6-carbonitrile frameworks 9 and 12, respectively. Also, in silico predictive theoretical molecular docking studies for bioactive synthesized scaffolds against both HER2 and 6BBP displayed an optimistic result for compounds 2 b, 5, 9, and 12 highlighting their expediency as up-and-coming candidates for future preclinical trials. Additionally, all compounds were assessed as antibacterial agents against various types of four candidates of bacteria in the presence of ampicillin as a reference. Notably, compounds 6, 7, and 12 showed promising antibacterial potential against Bacillus subtilis with activity indexes (69.6, 91.3, and 82.6 %), respectively.

[PMID: 37934155 DOI: 10.1002/chem.202303118] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Revised: 10/28/2023] [Accepted: 11/07/2023] [Indexed: 11/08/2023]
Abstract
An electrooxidative C-H functionalization is a widely accepted route to obtain sulfur-containing arenes and heteroarenes. However, this process often involves using non-recyclable supporting electrolytes, (co)solvents like hexafluoroisopropanol, additives like acid, or catalysts. The use of additional reagents can increase costs and waste, reducing atom efficiency. Moreover, unlike other nitrogen-containing heterocycles, there have only been sporadic reports of electrochemical C-H functionalization in fused pyrimidin-4-ones, and an electrolyte-free process has yet to be developed. This work demonstrates that such anodic coupling reactions can be performed in an all-green electrolytic system without using such additional electrolytes or HFIP, maintaining a high atom economy. This C-H functionalization strategy utilizes inexpensive sodium sulfinates and ammonium thiocyanate as sulfonylating and thiocyanating agents in an undivided cell at a constant current, using a mixture of CH3 CN/H2 O as solvent at room temperature. Thus, fused pyrimidin-4-ones can be selectively converted into C3-sulfonylated and -thiocyanated derivatives in moderate to good yields.

Abstract
Irradiation of mixtures of title diazonium salts and heteroarenes with green light (510 nm) in the presence of eosin Y disodium salt (EY-Na2) as a photocatalyst furnished the corresponding arylation products in 8-63% yields. The proposed photocatalytic cycle is analogous to that proposed previously for closely related photoredox C-H arylations with aryl diazonium salts as aryl radical sources. This method has a broad substrate scope and represents a metal-free alternative for the synthesis of 3-heteroaryl-substituted 4H-quinolizin-4-ones and azino- and azolo-fused pyrimidones with a bridgehead nitrogen atom.

Abstract
An expeditious metal free C-3 chalcogenation of 4H-pyrido[1,2-a]pyrimidin-4-one has been devised to synthesize diversely orchestrated 3-ArS/ArSe derivatives in high yields (up to 95%). This operationally simple reaction proceeds under mild reaction conditions, can be executed in gram scale, and also highlights broad functional group tolerance. Preliminary experimental investigation suggests a radical mechanistic pathway for these transformations.

Abstract
Chemokines and their receptors are known to play important roles in disease. More than 40 chemokine ligands and 20 chemokine receptors have been identified, but, to date, only two small molecule chemokine receptor antagonists have been approved by the FDA. The chemokine receptor CXCR3 was identified in 1996, and nearly 20 years later, new areas of CXCR3 disease biology continue to emerge. Several classes of small molecule CXCR3 antagonists have been developed, and two have shown efficacy in preclinical models of inflammatory disease. However, only one CXCR3 antagonist has been evaluated in clinical trials, and there remain many opportunities to further investigate known classes of CXCR3 antagonists and to identify new chemotypes. This Perspective reviews the known CXCR3 antagonists and considers future opportunities for the development of small molecules for clinical evaluation.

Abstract
BACKGROUND AND PURPOSE The chemokine receptor CXCR3 is implicated in a variety of clinically important diseases, notably rheumatoid arthritis and atherosclerosis. Consequently, antagonists of CXCR3 are of therapeutic interest. In this study, we set out to characterize binding sites of the specific low MW CXCR3 antagonist VUF10085 and the broad spectrum antagonist TAK-779 which blocks CXCR3 along with CCR2 and CCR5. EXPERIMENTAL APPROACH Molecular modelling of CXCR3, followed by virtual ligand docking, highlighted several CXCR3 residues likely to contact either antagonist, notably a conserved aspartate in helix 2 (Asp-112(2:63) ), which was postulated to interact with the quaternary nitrogen of TAK-779. Validation of modelling was carried out by site-directed mutagenesis of CXCR3, followed by assays of cell surface expression, ligand binding and receptor activation. KEY RESULTS Mutation of Asn-132(3.33) , Phe-207 and Tyr-271(6.51) within CXCR3 severely impaired both ligand binding and chemotactic responses, suggesting that these residues are critical for maintenance of a functional CXCR3 conformation. Contrary to our hypothesis, mutation of Asp-112(2:63) had no observable effects on TAK-779 activity, but clearly decreased the antagonist potency of VUF 10085. Likewise, mutations of Phe-131(3.32) , Ile-279(6.59) and Tyr-308(7.43) were well tolerated and were critical for the antagonist activity of VUF 10085 but not for that of TAK-779. CONCLUSIONS AND IMPLICATIONS This more detailed definition of a binding pocket within CXCR3 for low MW antagonists should facilitate the rational design of newer CXCR3 antagonists, with obvious clinical potential.

Abstract
A number of uncommon, clinically diverse and poorly understood inflammatory skin diseases are linked by the presence of a set of histopathological elements that have traditionally been referred to as the "lichenoid tissue reaction/interface dermatitis" (LTR/IFD). The prototypic skin disease in this category is lichen planus. However, the LTR/IFD can also be seen in skin disorders associated with systemic illnesses (lupus erythematosus, dermatomyositis), and the skin changes of potentially fatal disorders such as graft-versus-host disease, Stevens-Johnson syndrome, and toxic epidermal necrolysis. It has been traditionally felt that cytotoxic T-lymphocytes represent the final effector cell type for the epidermal basal cell layer injury pattern that is common to LTR/IFD disorders. Recent work has suggested that a number of different LTR/IFD skin disorders share a common inflammatory signaling pathway involving the actions of plasmacytoid dendritic cell-derived IFN-alpha. This signaling pathway appears to amplify cytotoxic T cell injury to the epidermal basal cell compartment. This review will summarize the work implicating this pathway as well as the other cellular and molecular mechanisms that are thought to be responsible for the prototypic LTR/IFD disorder, lichen planus. It is hoped that a better understanding of the immunological commonalities shared by various LTR/IFD disorders will lead to more effective safer treatment options for these illnesses.

Abstract
Chemokine receptors have a key role in the pathogenesis of autoimmune diseases, inflammation and viral infection. However, with the exception of selective CCR5 antagonists for HIV, the promise of obtaining new therapeutics related to chemokine receptors has not yet been realized. This article highlights some of the recent failures in the clinical trials of chemokine receptor antagonists and explores possible reasons as to why this might have occurred. Such reasons include the lack of predictability of animal models and redundancy of the target. A potential solution could be to develop drugs that target more than one receptor--known as polypharmacology--which could be a novel way to generate effective therapeutics.
