Abstract
Pyridones are versatile building blocks in organic synthesis and a privileged motif in drug discovery. However, N-substituted 2-pyridones bearing an α-tertiary carbon, cyclopropyl, or heterocycle off of the pyridone nitrogen atom remain challenging to prepare. Herein, we describe the efficient synthesis of a large variety of N-substituted 2-pyridones from ethyl nitroacetate and readily available primary amine building blocks, which can be utilized on a large scale and in parallel medicinal chemistry applications.

Abstract
A one-pot Curtius rearrangement of dienyl carboxylic acids followed by a 6π-electrocyclization process to form substituted 2-pyridone products has been developed. Dienyl isocyanates generated from aliphatic acids were more reactive than their aromatic counterparts. Additionally, substitution patterns of the carboxylic acids had an impact on the efficiency of the cyclization.

Abstract
Abstract
2-Pyridone is considered as one of the most famous efficient pharmaceutical compounds. Many approaches were discovered to synthesize 2-pyridone. In this present research, chloroacetylation of benzylamine at simple conditions, EtONa/EtCOONa produced N-benzyl-2-chloroacetamide 2. Compound 2 was allowed to react with different reagents. These reagents are acetylacetone, ethyl cyanoacetate, ethyl acetoacetate, and diethyl malonate, creating 2-pyridone derivatives with a good yield. The structures of the prepared compounds were elucidated by spectral data (IR, 1HNMR, and 13CNMR). The synthesized compound was tested for its antimicrobial activity against the Gram-positive (Staphylococcus aureus) and the Gram-negative (Escherichia coli) bacteria. In addition, the antifungal activities of the compounds were tested against two fungi (Candida albicans and Aspergillus flavus). Molecular docking studies were applied using the Autodock vina method. Theoretical methods prove all the experimental results by using molecular docking using Autodock vina and by ADEMT studies. The docking results represent that compound 20 had the best docking free energy, and it is the effective compound toward the selected bacterial and fungal proteins. ADME studies showed that the only compound 18 could cross the blood–brain barrier, and compound 15 was predicted to be soluble.

Abstract
In this article, a series of benzothiazole-bearing N-sulfonamide 2-pyridone derivatives were synthesized via the reaction of benzothiazole sulfonylhydrazide with sodium salts of both (hydroxymethylene) cycloalkanones and unsaturated ketones, as well as ethoxymethylene derivatives. The structures of the resultant compounds were confirmed using IR, 1H NMR, 13C NMR, 1H-1H correlation spectroscopy (COSY), 1H-13C heteronuclear multiple bond coherence (HMBC), and 1H-13C heteronuclear multiple quantum coherence (HSQC) spectral analysis and elemental analysis. The newly synthesized compounds were evaluated in vitro for their antiviral activities against the HSV-1, HAV HM175, HCVcc genotype 4, CBV4, and HAdV7 viruses. Additionally, the compounds were examined for their cytotoxic effect on five normal cell lines. It was observed that five compounds were found to possess viral reduction of 50% or more against CBV4 with significant IC50, CC50, and SI values. In the case of HSV-1 and HAV HM175 viruses, three compounds have shown more than 50% reduction, while in the case of HCVcc genotype 4 and HAdV7 viruses, only two compounds demonstrated more than 50% reduction. Furthermore, the physicochemical properties of the most active compounds were evaluated. The two most potent compounds against HSV-1 virus, 7e and 13a, were evaluated for their inhibitory activity against USP7. Docking studies using Molecular Operating Environment (MOE) were used to identify the interactions between 7e and 13a compounds and the active site of the USP7 enzyme.

Abstract
Carbon dots (CDs) have been progressively attracting interest as novel environmentally friendly and cost-effective luminescent nanoparticles, for implementation in light-emitting devices, solar cells, photocatalytic devices and biosensors. Here, starting from a cost-effective bottom-up synthetic approach, based on a suitable amphiphilic molecule as carbon precursor, namely cetylpyridinium chloride (CPC), green-emitting CDs have been prepared at room temperature, upon treatment of CPC with concentrated NaOH solutions. The investigated method allows the obtaining, in one-pot, of both water-dispersible (W-CDs) and oil-dispersible green-emitting CDs (O-CDs). The study provides original insights into the chemical reactions involved in the process of the carbonization of CPC, proposing a reliable mechanism for the formation of the O-CDs in an aqueous system. The ability to discriminate the contribution of different species, including molecular fluorophores, allows one to properly single out the O-CDs emission. In addition, a mild heating of the reaction mixture, at 70 °C, has demonstrated the ability to dramatically decrease the very long reaction time (i.e. from tens of hours to days) at room temperature, allowing us to synthesize O-CDs in a few tens of minutes while preserving their morphological and optical properties.

Abstract
Background:Perturbation of nucleic acids structures and confirmation by small molecules through intercalation binding is an intriguing application in anticancer therapy. The planar aromatic moiety of anticancer agents was inserted between DNA base pairs leading to change in the DNA structure and subsequent functional arrest.Objective:The final scaffold of the target compounds was annulated and linked to a benzotriazole ring. These new pharmacophoric features were examined as antiviral and anticancer agents against MCF7 and their effect on DNA damage was also assessed.Methods:A new series of fully substituted 2-oxopyridine/2-thioxopyridine derivatives tethered to a benzotriazole moiety (4a-h) was synthesized through Michael cyclization of synthesized α,β- unsaturated compounds (3a-e) with appropriate active methylene derivatives. The DNA damage study was assessed by comet assay. In silico DNA molecular docking was performed using Open Eye software to corroborate the experimental results and to understand molecule interaction at the atomic level.Results:The highest DNA damage was observed in Doxorubicin, followed by 4h, then, 4b, 4g, 4f, 4e, and 4d. The docking study showed that compound 4h formed Hydrogen Bonds (HBs) as a standard ligand with GSK-3. Compound 4h was the most active compound against rotavirus Wa, HAVHM175, and HSV strains with a reduction of 30%, 40%, and 70%, respectively.Conclusion:Compound 4h was the most active compound and could act as a prospective lead molecule for anticancer agent.
