Abstract
Candidiasis is one of the most serious microbial infections in the world. One of the main virulence factors for Candida albicans is the crucial secretion of aspartic proteases (Saps). Saps are hydrolytic enzymes that play a major role in many fungal pathophysiological processes as well as in many levels of the associations between the fungus and its host. In this work, we report on the synthesis, characterization, and anti-candida agent evaluation of a family of 13 imidazolidine-based aspartate protease inhibitors. In vitro and in silico enzyme inhibition studies have confirmed these compounds' ability to inhibit fungal aspartate protease. Based on the molecular mechanistic value scores from molecular docking and MD simulations, we selected the top compounds 5b (binding energy -13.90 kcal/mol) and 5m (binding energy -12.94 kcal/mol) from among 5a-l based on the molecular mechanistic value scores from molecular docking and MD simulations for use in in vitro validations. In the results, imidazolidine derivatives showed strong aspartic protease inhibition activity. In conclusion, compounds 5b and 5m were found as potent anti-candida agents and screened for further pre-clinical and clinical validations.

Abstract
Continued emerging resistance of pathogens against the clinically approved candidates and their associated limitations continuously demand newer agents having better potency with a more suited safety profile. Quinoline nuclei containing scaffolds of natural and synthetic origin have been documented for diverse types of pharmacological activities, and a number of drugs are clinically approved. In the present review, we unprecedentedly covered the biological potential of 4-substituted quinoline and elaborated a rationale for its special privilege to afford the significant number of approved clinical drugs, particularly against infectious pathogens. Compounds with 4-substituted quinoline are well documented for antimalarial activity, but in the last two decades, they have been extensively explored for activity against cancer, tuberculosis, and several other pathogens including viruses, bacteria, fungi, and other infectious pathogens. In the present study, the anti-infective spectrum of this scaffold is discussed against viruses, mycobacteria, malarial parasites, and fungal and bacterial strains, along with recent updates in this area, with special emphasis on the structure-activity relationship.

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
Although most of the heterocycles have been reported to possess a significant pharmacological activity, only a few of them, namely quinoline derivatives, have exhibited the finest biological activities. Despite the few medicinal properties of the plain quinoline molecule, its derivatives exhibit diverse pharmacological properties such as anticancer, anti-inflammatory, antibacterial, antiviral, antifungal, antiprotozoal activities, and so on. The potential antimicrobial properties of the quinoline derivatives are evident from the decades of research on these derivatives. Owing to limitations like drug resistance, high cost, severe side effects, and less bioavailability of previously synthesized antimicrobial agents, these drugs have become obsolete in recent years. Hence, the design of more efficient antimicrobial drugs must be given topmost priority. A breakthrough in drug discovery is a must to prevent malevolent microbial diseases. Addressing all these issues, researchers have been continuously contributing to antimicrobial drug discovery. Herein, a short description of the pharmacology of antimicrobial agents such as antibacterials and antifungals synthesized recently is provided. The versatile derivatization of the quinoline moiety leading to significant antimicrobial potencies is discussed, considering the structure-activity relationship.

Abstract
Diaryl ether (DE) is a functional scaffold existing widely both in natural products (NPs) and synthetic organic compounds. Statistically, DE is the second most popular and enduring scaffold within the numerous medicinal chemistry and agrochemical reports. Given its unique physicochemical properties and potential biological activities, DE nucleus is recognized as a fundamental element of medicinal and agrochemical agents aimed at different biological targets. Its drug-like derivatives have been extensively synthesized with interesting biological features including anticancer, anti-inflammatory, antiviral, antibacterial, antimalarial, herbicidal, fungicidal, insecticidal, and so on. In this review, we highlight the medicinal and agrochemical versatility of the DE motif according to the published information in the past decade and comprehensively give a summary of the target recognition, structure-activity relationship (SAR), and mechanism of action of its analogues. It is expected that this profile may provide valuable guidance for the discovery of new active ingredients both in drug and pesticide research.

Abstract
BACKGROUND The derivatives of xanthene are known to have promising anticancer properties, in comparison to xanthene itself. OBJECTIVE The object of our study was to develop few xanthene derivatives (a family of fifteen novel 3,4,6,7- tetrahydro-3,3-dimethyl-9-phenyl-2H-xanthene-1,8(5H, 9H)-diones encoded as 4a-4m), which were effectively prepared through regioselective synthesis approach, and to test their anticancer effects. METHODS A series of cell lines were used in this study, first to assess the cytotoxicity and then the drug efficacy of target compounds, consecutively. Prior to MTT assay, the compounds were analysed for their antioxidant properties, since oxidative stress is an important factor in the development of many cancer types. The anticancer properties of 4a-m have been assessed over in silico (molecular docking and ADMET assessments) and in vitro (MTT assay) methods. RESULTS Compounds 4h and 4i showed a relative percentage anticancer activity of 86.25±1.25 & 89.74±1.64 against BT474 (ER+HER2+), and 90.56±1.18 & 93.24±1.80 against MCF-7 (ER-HER2), respectively. CONCLUSION The animal model and pre-clinical studies for 4h and 4i should be performed in order to develop them as future anticancer agents.

Abstract
A family of 12 triazolo-pyridazine-6-yl-substituted piperazines (5a-l) was synthesized and evaluated for their Dipeptidyl peptidase-4 (DPP-4) inhibition potentials in order to develop them as anti-diabetic medications. In the two-step synthesis process, 6-chloro-3-(m-tolyl)-[1,2,4]triazolo[4,3-b]pyridazine was synthesized with one-pot mode using pyridine, 3,6-dichloropyridazine 5-(3-methyl-phenyl)tetrazole in toluene. Conjugating corresponding 2° amines with 6-chloro-3-(m-tolyl)-[1,2,4]triazolo[4,3-b]pyridazine afforded the target triazolo-pyridazine-6-yl-substituted piperazines (5a-l). DPP-4 inhibition potential of these compounds was testified in silico and in nitro along with their insulinotropic activities in 832/13 INS-1 cells. H2O2 radical scavenging assay and MTT assay were conducted to assess the antioxidant and cytotoxicity of these compounds respectively. Molecular docking and ELISA based enzyme inhibition assay results revealed the strong inhibition potential of the target compounds.

Synthesis and discovery of pyrazolo-pyridine analogs as inflammation medications through pro- and anti-inflammatory cytokine and COX-2 inhibition assessments. Bioorg Chem 2019; 94:103484. [PMID: 31796215 DOI: 10.1016/j.bioorg.2019.103484] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2019] [Revised: 09/08/2019] [Accepted: 11/26/2019] [Indexed: 12/15/2022]
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
Efforts were taken to synthesis and characterize 2-amino-1-methyl-1H-imidazole-4(5H)-one derivatives (4a-u) through a four-step reaction. The achieved compounds in remarkable yield have characterized through standard analytical techniques such as FTIR, LC-MS, NMR, HRMS, and elemental analysis. Present study mainly aimed to evaluate 4a-u as G protein-coupled receptors (GPCR). In the mechanism, stimulation of phosphoinositide 3-kinase (PI3K) and Akt (protein kinase B) is a general reaction activated by a series of membrane-bound receptors such as GPCR. Protease-activated receptor-1 (PAR1) is a subfamily of related GPCR, which triggered by the division of fragment of its extracellular domain. Therefore, molecular docking is done to ensure the inhibition of PAR1 and PI3Kinase. PI3Kinase is a chief enzyme in the development of breast cancer via the Akt/mTOR pathway. Thus, in vitro PI3Kinase inhibition and anti-breast cancer studies has also done to screen medicinally important compounds among (4a-u). Based on the best binding affinity, in vitro relative % activity and IC50 values, compounds 4a, 4g, 4i, 4n, and 4u were screened for further preclinical studies in animal model evaluations.

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.

Eur J Med Chem 2017; 139:454-460. [PMID: 28818769 DOI: 10.1016/j.ejmech.2017.08.001] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2017] [Revised: 06/29/2017] [Accepted: 08/01/2017] [Indexed: 11/25/2022]
Abstract
Efforts were made to synthesize a series of substituted methoxybenzyl-sulfonyl-1H-benzo[d]imidazole derivatives (8a-l) and investigate their anti-ulcer therapeutics. Prior to evaluating antiulcer potentials of 8a-l, a preliminary binding assay against H+/K+-ATPase from goat gastric mucosa was carried out, since it plays an important role in the ulcer development. In order to get more insight into the binding mode of the compounds to H+/K+-ATPase, a molecular docking study was carried out and the best binding affinities were unveiled. Many of the substituted methoxybenzyl-sulfonyl-1H-benzo[d]imidazole derivatives (8a-l) were active for the proposed activity. The key finding was that, least inhibitory constant (ki) values of 8a-l were found between 0.02 and 1.8 μM in the molecular docking study. Almost the same range was reflected/correlated in the H+/K+-ATPase inhibition assay (IC50 0.14-1.29 μM). Remarkably, compounds 8a-l showed a relative activity percentage range of 72-92%. Efficient HRBC membrane stabilization activity of 8a-l ensured the non-harm/safety and the suitability/alternative towards anti-ulcer therapy.
