Abstract
Herein, we report a new synthetic strategy for 2-(pyridin-2-yl)phenols and 2-(pyridin-2-yl)anilines catalyzed by a Pd/C-ethylene system. The starting materials, 2-(pyridin-2-yl)cyclohexan-1-ones, can be easily prepared by the reaction of substituted pyridine N-oxide and cyclohexanones. The most useful feature of this method is that both 2-(pyridin-2-yl)phenols and 2-(pyridin-2-yl)anilines are easily synthesized independently using the same compound as a starting material, simply by adding or not adding a nitrogen source.

Abstract
Cyclooxygenase-2 (COX-2) is a key-type enzyme playing a crucial role in cancer development, making it a target of high interest for drug designers. In the last two decades, numerous selective COX-2 inhibitors have been approved for various clinical conditions. However, data from clinical trials propose that the prolonged use of COX-2 inhibitors is associated with life-threatening cardiovascular side effects. The data indicate that a slight structural modification can help develop COX-2 selective inhibitors with comparative efficacy and limited side effects. In this regard, secondary metabolites from natural sources offer great hope for developing novel COX-2 inhibitors with potential anticancer activity. In recent years, various nature-derived organic scaffolds are being explored as leads for developing new COX-2 inhibitors. The current review attempts to highlight the COX-2 inhibition activity of some naturally occurring secondary metabolites, concerning their capacity to inhibit COX-1 and COX-2 enzymes and inhibit cancer development, aiming to establish a structure-activity relationship.

Abstract
A novel ANAP (Aspergillus niger from alkaline protease) catalyzed one pot three component approach in the synthesis of new thiazolidinedione festooned quinoline analogues via Knoevenagel condensation and N-alkylation have been reported. The catalytic effect of enzyme was monitored and optimized by adjusting various parameters including catalyst concentration, choice of solvent and temperature. The isolated alkaline protease exhibits favorable features for the reaction response such as the shorter reaction time, simple work-up procedure, clean reaction profiles and excellent product yields through reusability of the catalyst upto five cycles. In silico molecular docking simulations were carried out to find out the effective binding affinity of the synthesized quinoline analogues 4(a-i) towards PPARγ protein (Id-2XKW). In vitro α-amylase and α-glucosidase assays were performed for hypoglycemic activity evaluation. In vivo hypoglycemic studies carried out on streptozotocin (SZT) induced diabetic male albino rats have shown that compounds 4e and 4f significantly reduced blood glucose levels with percentage reduction of 43.7 ± 0.91 and 45.6 ± 0.28 at a concentration of 50 mg/kg body wt. The results obtained from molecular docking simulations and in vitro enzyme assays are in consistent with in-vivo studies which clearly demonstrated that out of the synthesized quinoline analogues, compounds 4e and 4f possess promising hypoglycemic activity which was on par to that of standards pioglitazone and rosiglitazone respectively.

Abstract
Background: Macrophages play a serious part in the instigation, upkeep, and resolution of inflammation. They are activated or deactivated during inflammation progression. Activation signals include cytokines (IF-γ, granulocyte-monocyte colony-stimulating factor (GM-CSF), and TNF-α), extracellular matrix proteins, and other chemical mediators. Activated macrophages are deactivated by anti-inflammatory cytokines (IL-10 and TGF-β (transforming growth factor-beta) and cytokine antagonists that are mainly produced by macrophages. Based on this, the present study aimed to develop novel (E)-Benzylidene-indazolpyridin methanones (Cpd-1-10) as effective anti-inflammatory agents by analyzing pro- and anti-inflammatory cytokine levels in macrophages. Objectives: To determine the anti-inflammatory effect of indazolpyridin-methanones by examining pro- and anti-inflammatory interleukin levels in J77A.1 macrophages. Methods: Expression of cytokines such as TNF-α, IL-1β, IL-6 and IL-10 serum levels measured by ELISA method. Anti-cancer and cytotoxicity studies were carried out by MTT assay. COX-2 seems to be associated with cancers and atypical developments in the duodenal tract. So, a competitive ELISA based COX-2 inhibition assay was done. To validate the inhibitory potentials and to get more insight into the interaction of COX-2 with Cpd1-10, molecular docking was performed. Results: Briefly, the COX-2 inhibitory relative activity was found to be in between the range of 80-92% (Diclofenac showed 84%, IC50 0.95 µM). Conclusion: Cytotoxicity effect of the compounds against breast cancer cell lines found excellent and an extended anticancer study ensured that these compounds are also alternative therapeutic agents against breast cancer. Among all the tested cancer cell lines, the anti-cancer effect on breast cancer was exceptional for the most active compounds Cpd5 and Cpd9.

Abstract
A novel one-pot multicomponent reaction was performed to synthesize different imidazole and benzotriazole (BTA) isatin-based medicinally important compounds using (p-TSA·H2O) as an economical and operative acid catalyst. The yield of the products was found to be up to a maximum of 92% when using this catalyst. Antioxidant, anti-breast cancer and anti-inflammatory activities of these 13 isatin-based derivatives (named as 5a-m) were assessed. The inhibitory effects of these compounds were tested in vitro against cyclooxygenase-2 (COX-2, an enzyme responsible for inflammation) and phosphoinositide-3 kinase (PI3K, a key enzyme in breast cancer). "Among the 13 isatin-based Imidazole derivatives, five compounds (5a, 5d, 5f, 5 k and 5l) were found to exhibit anti-inflammatory as well as anti-cancer activity, which was validated using HRBC stabilization assay (to show anti-inflammatory activity) and cytotoxicity in MCF-7 (breast cancer cell line) to provide proof for anti-cancer property of the compounds". The molecular interactions between the two enzymes were probed using molecular docking. Structure-Activity Relationship (SAR) and ADMET prediction results were also useful to screen the most effective imidazole derivatives and to establish them as putative COX-2 inhibitors/anti-inflammatory drugs. These selected compounds which showed appreciable activity against COX-2 and PI3K are promising drug candidates for the treatment of breast cancer and inflammation which is often associated with breast cancer pathophysiology.

Abstract
This article briefs about the efforts taken to synthesis, characterize and develop (E)-5-methyl-2-phenyl-3-(thiophen-2-yl)-7-(thiophen-2-ylmethylene)-3,3a,4,5,6,7-hexahydro-2H-pyrazolo[4,3-c]pyridine and their analogs. In the two-step reaction, the first step is the synthesis of (3Z,5E)-1-methyl-3,5-bis(thiophen-2-ylmethylene)piperidin-4-one derivatives (3a-l) by stirring the mixture of 1-methylpiperidin-4-one and substituted thiophene-carbaldehydes in presence of methanol. In the second and final step, compounds 3a-l were refluxed with phenyl-hydrazine to achieve the target compounds (E)-5-methyl-2-phenyl-3-(thiophen-2-yl)-7-(thiophen-2-ylmethylene)-3,3a,4,5,6,7-hexahydro-2H-pyrazolo[4,3-c]pyridine and their analogs (5a-l) in good yield. These compounds were used to assess their inflammation regulation properties in macrophages by executing quantitative pro-inflammatory and anti-inflammatory proteins such as TNF-α, IL-1β, IL6, and IL-10 respectively. In silico and in vitro COX-2 inhibition studies helped to understand the molecular interaction or plausible mechanism during the inflammation regulation that showed by the compounds. In the results, among the 12-member family of pyrazolo-pyridines (5a-l), 5a, 5b, 5g, and 5j were showed excellent in silico binding affinity (1-10 nM), least binding energy (-12.45 to -14.27 kcal/mol) and in vitro COX-2 inhibition (relative percentage activity maximum 96.42%). Thus, these compounds perhaps to be future anti-inflammatory drugs.

Abstract
A series of new 1,2,4-triazole and 1,3,4-oxadiazole derivatives was obtained via several steps sequential reactions of phenyl piperazine. Then, these compounds were converted to the corresponding fluoroquinolone hybrids via one pot three component Mannich reaction. All the reactions were examined under conventional and microwave mediated conditions, and optimum conditions were determined. The effect of different solvents and microwave power on microwave prompted reactions was investigated as well. All the newly synthesized compounds were characterized by FTIR, 1H NMR, 13C NMR and EI MS spectral techniques. The antimicrobial activity, DNA gyrase and Topoisomerase IV inhibition potentials were performed. The results obtained showed that fluoroquinolone hybrids possess good antimicrobial activity. Moreover, Fluoroquinolone-azole-piperazine hybrids synthesized in the present study displayed excellent DNA gyrase inhibition. To unveil the interaction mode of compounds to receptor, a molecular docking study was performed. With an average least binding energy of -9.5 kcal/mol, all compounds were found to have remarkable inhibitory potentials against DNA gyrase (E. coli).

Abstract
A green and efficient straightforward tactic for the one-pot regioselective synthesis of novel 10,10-dimethyl-9,10,11,11a-tetrahydro-6H-spiro[chromeno[4,3-b]chromene-7,3'-indoline]-2',6,8 (7aH) -triones (4a-n) in one-pot modus has been established using eco-friendly p-toluenesulphonic acid as catalyst. Among the solvents that were used for synthesis, 4a-n were suitably synthesized with maximum yield (90-98%) in water. We avoided column purification and the formed by-product in the process is environmental-friendly. Hence, this reaction may consider as an astonishing piece work in this study, why because, the reaction mechanism that depends on the nature of the group attached to the isatin ring nitrogen atom. The main advantage of this protocol includes short reaction time, good yield, easy to work-up, practical simplicity, high regioselectivity and reduced pollutant, cost and avoids tedious purification. These pharmaceutically important compounds (4a-n) were recognized for their alkaline phosphatase inhibition and prostate cancer medication capabilities. The selective activity relation between alkaline phosphatase and prostate cancer was unveiled through the interaction of 4a-n to Human alkaline phosphatase (PDB ID: 1EW2).

Abstract
Aim: Due to their effective binding affinity to receptors which are responsible for various diseases, benzimidazoles are often bioactive. Present study intended and carried out to synthesis, characterize and develop benzimidazole-based antiulcer drugs. Materials & methods: Established 8a–l were evaluated for gastric antisecretory/antiulcer properties using freshly prepared H+-K+-ATPase from goat fundus mucosa. Molecular docking was carried out to unveil best binding affinities with H+-K+-ATPase (protein data bank ID: 2XZB). Results: The obtained least inhibitory constant of 8a–l (18–92 nM) was comparable to the in vitro H+-K+-ATPase inhibition (IC50: 24–122 nM). Furthermore, the lethal effect of 8a–l to colon cancerous cells and nonharm effect to the normal cells was recognized through cytotoxicity studies. Conclusion: After all in silico, in vitro experimental and structure–activity relationship predictions, the antiulcer druggability potential of 8a–l was recognized. A future drug development study for the most potent compounds among 8a–l is strongly indorsed.
