Abstract
An air-stable, robust, and well-defined copper(II)-7-azaindole-N-oxide-based catalyst [Cu2II(7-AINO)4] (abbreviated as Cu(II)-7-AINO) has been demonstrated as an efficient catalyst for various Ullmann-type coupling reactions. This easily prepared and cost-effective catalyst facilitates the arylation and heteroarylation of diverse N-, S-, and O-nucleophiles, including azoles, aminoazoles, (hetero)arylthiols, and phenols. Notably, they also exhibit substantial compatibility with a wide range of functional groups. Furthermore, the catalyst demonstrates significant selectivity for -NH sites of aminoazoles and -SH sites of aminothiophenols over -NH2 sites in both cases, enhancing its versatility. Exploiting the catalyst's chemo- and regioselective properties, we have successfully demonstrated the applicability of our methodology in synthesizing various drug molecules. Specifically, Epirizole analogue, Nilotinib, and Vortioxetine were successfully synthesized using our protocol.

Abstract
In recent decades, the utilization of microwave energy has experienced an extraordinary surge, leading to the introduction of innovative and revolutionary applications across various fields of chemistry such as medicinal chemistry, materials science, organic synthesis and heterocyclic chemistry. Herein, we provide a comprehensive literature review on the microwave-assisted organic synthesis of selected heterocycles. We highlight the use of microwave irradiation as an effective method for constructing a diverse range of molecules with high yield and selectivity. We also emphasize the impact of microwave irradiation on the efficient synthesis of N- and O-containing heterocycles that possess bioactive properties, such as anti-cancer, anti-proliferative, and anti-tumor activities. Specific attention is given to the efficient synthesis of pyrazolopyrimidines-, coumarin-, quinoline-, and isatin-based scaffolds, which have been extensively studied for their potential in drug discovery. The article provides valuable insights into the recent synthetic protocols and trends for the development of new drugs using heterocyclic molecules.

Abstract
The present investigation of minutiae to acquire structural information of the novel pyrazole-coumarin hybrids (PC1-PC10) synthesized using ultrasound methods and characterized using different spectroscopic techniques: mass, 1H-NMR, 13 C-NMR and IR spectroscopy, and theoretically explored using the DFT approach with a B3LYP/6-311G (d, p) basis set, and there in vitro, antagonistic efficacy against α-amylase and mycobacterium-TB H37Rv are described in this article. Pyrazole-coumarin hybrids (PC1-PC10) showed α-amylase inhibition ranging from IC50 (0.32-0.58 mM) when compared with acarbose (IC50 = 0.34 mM). Similarly, Mycobacterium-TB H37Rv strain inhibition screening showed MIC values ranging from 62.5 to 1000 µg/mL when compared with rifampicin and isoniazid MIC = 0.25 and 0.20 µg/mL, respectively. Molecular docking and MD simulation studies were performed to determine the active sites and rationalize the activities of the active compounds. To investigate the binding conformation and dynamics responsible for their activity, the three most active compounds (PC1, PC3 and PC6) were docked into the porcine pancreatic α-amylase active site (PDB ID:1OSE), and mycobacterium-TB H37Rv active site (PDB ID: 4TZK). The binding interactions between PC1, PC3, and PC6 with α-amylase were like those responsible for inhibiting α-amylase by acarbose. Also, the mycobacterium-TB H37Rv inhibiting responsible residues were compared with standard isoniazid and rifampicin.Communicated by Ramaswamy H. Sarma.

Abstract
Diabetes mellitus is a metabolic disorder and more than 90% of diabetic patients suffer from type-2 diabetes, which is characterized by hyperglycemia. α-Glucosidase inhibition has become an appropriate approach to tackle high blood glucose levels. The current study was focused on synthesizing coumarin-hydrazone hybrids (7a-i) by using facile chemical reactions. The synthesized compounds were characterized by using 1H-NMR, 13C-NMR, and IR. To evaluate their anti-diabetic capability, all of the conjugates were screened for in vitro α-glucosidase inhibitory activity to reveal their therapeutic importance. All of the compounds (except 7b) demonstrated significant enzyme inhibitory potential with IC50 values ranging between 2.39-57.52 μM, as compared to the standard inhibitor, acarbose (IC50 = 873.34 ± 1.67 μM). Among them, compound 7c is the most potent α-glucosidase inhibitor (IC50 = 2.39 ± 0.05 μM). Additionally, molecular docking was employed to scrutinize the binding pattern of active compounds within the α-glucosidase binding site. The in silico analysis reflects that hydrazone moiety is an essential pharmacophore for the binding of compounds with the active site residues of the enzyme. This study demonstrates that compounds 7c and 7f deserve further molecular optimization for potential application in diabetic management.

Abstract
The objective of the current study is to evaluate the prospective of liquisolid formulation to improve the dissolution rate of ketoprofen and thereby the bioavailability. Different batches of liquisolid were prepared using polyethylene glycol 200 as a solvent, microcrystalline cellulose, and aerosil 200 as carrier and coating material, respectively. Central composite design (32) was utilized to examine the effects of independent variables (load factor and excipient ratio) on dependent variables (solubility and % in vitro drug release). Differential scanning calorimetry, Fourier transform infrared spectroscopy, X-ray diffraction, and scanning electron microscopy techniques were employed for characterization of optimized batch (LS-10) of liquisolid formulation. The half-maximal inhibitory concentration (IC50) values for in vitro anti-inflammatory activity for liquisolid formulation exhibited a higher anti-inflammatory effect than ketoprofen and physical mixture. The statistical analysis of in vivo (anti-inflammatory and analgesic) activities data demonstrated that the test (optimized formulation) treatment group resulted in quick pharmacological response in Wistar rats and Albino mice when compared with standard (pure drug) and control treatment groups. The results obtained in the present study illustrated that the liquisolid formulation could be a propitious approach to increase the bioavailability of ketoprofen and could be used in oral therapy.

Abstract
Considering the astounding biomedicine properties of pharmaceutically active drug, 4-aminophenazone, also known as 4-aminoantipyrine, the work reported in this manuscript details the formation of novel cocrystals of rearranged 4-aminophenazone and 4-nitro-N-(4-nitrobenzoyl) benzamide in 1:1 stoichiometry under employed conditions for thiourea synthesis by exploiting the use of its active amino component. However, detailed analysis via various characterization techniques such as FT-IR, nuclear magnetic resonance spectroscopy and single crystal XRD, for this unforeseen, but useful cocrystalline synthetic adduct (4 and 5) prompted us to delve into its mechanistic pathway under provided reaction conditions. The coformer 4-nitro-N-(4-nitrobenzoyl) benzamide originates via nucleophilic addition reaction following tetrahedral mechanism between para-nitro substituted benzoyl amide and its acid halide (1). While the enamine nucleophilic addition reaction by 4-aminophenazone on 4-nitrosubstituted aroyl isothiocyanates under reflux temperature suggests the emergence of rearranged counterpart of cocrystal named N-(1,5-dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazole-4-carbonothioyl)-4-nitrobenzamide. Crystallographic studies reveal triclinic system P-1 space group for cocrystal (4 and 5) and depicts two different crystallographically independent molecules with prominent C–H···O and N–H···O hydrogen bonding effective for structure stabilization. Hirshfeld surface analysis also displays hydrogen bonding and van der Waals interactions as dominant interactions in crystal packing. Further insight into the cocrystal synthetic methodologies supported the occurrence of solution-based evaporation/cocrystallization methodology in our case during purification step, promoting the synthesis of this first-ever reported novel cocrystal of 4-aminophenazone with promising future application in medicinal industry.

Abstract
The present piece of research work is framed for improving the solubility of ketoprofen by forming co-crystal using fumaric acid as a coformer. Co-crystal of ketoprofen and fumaric acid was prepared by simple solvent-assisted grinding method, containing drug and coformer as independent variables and solubility and % drug release were assumed to be dependent variables. Differential scanning calorimetry, Fourier transform infrared spectroscopy, X-ray diffraction, nuclear magnetic resonance and scanning electron microscopy techniques were used to characterize the preparation of optimized batch of co-crystal and further, evaluated for in vitro and in vivo anti-inflammatory and analgesic activities. Based on results of solubility and dissolution rate studies the formulation showed magnified improvement in both the properties on co-crystallization. The values of Gibbs free energy are negative at all levels of carrier demonstrating spontaneity of the drug solubilization process. The IC50 value of optimized batch of co-crystal formulation and the pure drug was observed as 327.33 μg/ml and 556.11 μg/ml, respectively, demonstrating that co-crystal formulation possesses more percentage protection against protein denaturation than the drug ketoprofen. In vivo (anti-inflammatory and analgesic) activities revealed that optimized batch of co-crystal formulation delivered a rapid pharmacological response in Wistar rats and albino mice when compared with standard drug.

Abstract
One approach to overcome the antimicrobial resistance of many pathogens is to associate compounds with antimicrobial properties and obtain combinations superior compared to the effect of each compound. To identify a possible potentiating effect, we tested and analyzed the inhibitory effect of the combination of coumarin with two pyrazole derivatives, 1,1'-methandiylbis (3,5-dimethyl-1H-pyrazole (AM4) and 3,5-dimethyl-1H-pyrazol-1-yl) methanol 3,5-dimethyl-1-hydroxymethylpyrazol (SAM4). A clear synergistic effect was recorded when coumarin was associated with SAM4, in which case the Fractional Inhibitory Concentration Index (FICI) had a value equal to 0.468 for Citrobacter freundii, Proteus mirabilis, and E. coli. In the other cases, however, both the association between coumarin and AM4 and coumarin SAM4 had only an additive effect (FICI = 0.937-1.00). The bactericidal effect of the coumarin-pyrazole combination over time was better in all cases compared to the effect of the compounds used separately. The viability of the bacterial cells at sub-inhibitory concentrations of the tested compounds was variable, depending on both the type of compound and the bacterial strain.

Abstract
In this research work, silica nanoparticles and silica-gentamicin nanostructured solution were synthesized by using the microwave-assisted synthesis, in basic medium, using two silane precursors (tetraethylorthosilicate and octyltriethoxysilane) and the antibiotic (gentamicin sulfate). The prepared materials were characterized through Fourier transform infrared (FTIR) spectroscopy, TGA analysis, transmission electron microscopy (TEM), and atomic force microscopy (AFM) to investigate the morphology and structure. Antimicrobial studies of the silica-gentamicin nanostructured solution versus silica nanoparticles were performed against Pseudomonas aeruginosa, Staphylococcus aureus, and Escherichia coli. FTIR spectra showed that the gentamicin has been loaded to the silica nanoparticles. AFM analysis showed that the morphology of the silica-gentamicin nanostructured solution has changed, and agglomerations of particles are present at the surface. Antimicrobial testing, performed using the diffusion method through spot inoculation, indicates that the silica-gentamicin nanostructured solution exhibited activity against the resistant strain. The obtained silica-gentamicin solution can be used as biochemical agent for the prevention and treatment of microorganisms which are deposited on different surfaces (e.g., glass, plastic, ceramic).

Abstract
Although the hormone independent cytotoxic activity of several estradiol derivatives endowed with a simple substituent at C-2 has been reported so far, 2-heterocyclic and 2,3-condensed analogs are less investigated from both synthetic and pharmacological points of view. Therefore, novel A-ring-connected 2-pyrazoles of estradiol and, for comparison, their structurally simplified non-steroidal pairs were synthesized from estradiol 3-methyl ether and 6-methoxy-1,2,3,4-tetrahydronaphthalene. Friedel-Crafts acetylation of the protected phenolic compounds and subsequent O-demethylation led to ortho-substituted derivatives regioselectively, which were converted to arylhydrazones with phenylhydrazine, 4-tolylhydrazine and 4-chloro-phenylhydrazine, respectively, under microwave conditions. The hydrazones were subjected to cyclization with the Vilsmeier-Haack reagent immediately after preparation and the ring closure/formylation sequence resulted in steroidal and non-steroidal 4'-formylpyrazoles in moderate to good yields. During reductive transformations, 4-hydroxymethyl-pyrazoles were obtained, while oxidative lactonization of the 4-formylpyrazole moiety with the phenolic OH in the presence of the Jones reagent afforded A-ring-integrated pyrazolocoumarin hybrids and related analogs. Steroidal pyrazoles, which were produced as C-17 acetates due to acetylation of C-17 OH during the primary Friedel-Crafts reaction, underwent deacetylation in alkaline methanol to furnish 2-heterocyclic estradiol derivatives. Pharmacological studies revealed the overall and cancer cell-specific cytotoxicity of the derivatives and the half maximal inhibitory concentrations were obtained for the most promising compounds.

Abstract
In the present study piroxicam loaded starch nanoparticles were prepared to enhance the solubility of piroxicam by nanoprecipitation technique. The preparation of nanoparticles was carried out as per central composite experimental design protocol, having concentration of starch and drug as independent variables and particle size and polydispersity index (PdI) as dependent variables. The particle size and PdI of piroxicam loaded starch nanoparticles was found to be between 282–870 nm and 0.339–0.772, respectively. After the characterization by FT-IR, TGA, XRD and SEM studies, the optimized batch was evaluated for in-vitro release study, anti-inflammatory activity and anti-oxidant activity. The in-vitro anti-inflammatory activity of piroxicam loaded starch nanoparticles was found to be more than the pure drug piroxicam whereas the anti-oxidant activity of starch is found greater than starch nanoparticles. In-vitro release study showed 98.8% release in 2 h dissolution study following supercase II transport mechanism of drug release.

Abstract
This review is a compilation of the green synthetic methods used in the synthesis
of coumarin derivatives. Coumarins are a class of compounds with a pronounced wide
range of biological activities, which have found their application in medicine, pharmacology,
cosmetics and food industry. Their biological activity and potential application are
highly dependent on their structure. Therefore, many researchers have been performing
the synthesis of coumarin derivatives on a daily basis. High demands for their synthesis
often result in an increased generation of different waste chemicals. In order to minimize
the utilization and generation of toxic organic substances, green synthetic methods are applied
in this manner. These methods are getting more attention in the last few decades.
Green chemistry methods cover a wide range of methods, including the application of ultrasound
and microwaves, ionic liquids and deep eutectic solvents, solvent-free synthesis, mechanosynthesis
and multicomponent reactions. All typical condensation reactions for coumarin synthesis like Knoevenagel,
Perkin, Kostanecki-Robinson, Pechmann and Reformansky reactions, have been successfully performed using
these green synthetic methods. According to the authors mentioned in this review, not only these methods reduce
the utilization and generation of toxic chemicals, but they can also enhance the reaction performance in
terms of product yields, purity, energy consumption and post-synthetic procedures when compared to the conventional
methods. Due to the significance of coumarins as biologically active systems and the recent demands
of reducing toxic solvents, catalysts and energy consumption, this review provides a first full literature overview
on the application of green synthetic methods in the coumarin synthesis. It covers a literature search over
the period from 1995-2019. The importance of this work is its comprehensive literature survey on a specific
class of heterocyclic compounds, and those researchers working on the coumarin synthesis can find very useful
information on the green synthetic approaches to their synthesis. There are some reviews on the coumarin synthesis,
but most of them cover only specific reactions on coumarin synthesis and none of them the whole range
of green chemistry methods.

Abstract
Infections caused by Gram-positive and -negative bacteria are one of the foremost causes of morbidity and mortality globally. Antibiotics are the mainstay of therapy for bacterial infections, but the emergence and wide spread of drug-resistant pathogens have already become a huge issue for public healthcare systems. The coumarin moiety, which is ubiquitous in nature, could bind to the B subunit of DNA gyrase in bacteria and inhibit DNA supercoiling by blocking the ATPase activity; hence, coumarin derivatives possess potential antibacterial activity. Several coumarin-containing hybrids such as coumermycin A1, clorobiocin, and novobiocin have already been used in clinical practice for the treatment of various bacterial infections; thus, it is conceivable that hybridization of the coumarin moiety with other antibacterial pharmacophores may provide opportunities for the development of novel antibiotics. This review outlines the advances in coumarin-containing hybrids with antibacterial potential in the recent 5 years and the structure-activity relationships are also discussed.
