Abstract
A series of new Schiff bases containing the phenyl-ethynyl-phenyl system was synthesized and their thermal stability, photophysical and electrochemical properties were investigated. Moreover, DFT calculations were performed to obtain the optimized ground-state geometry and distribution of the HOMO and LUMO levels as well as IR spectra of the prepared compounds. It was found that, the photoluminescence of synthesized imines was negligible in all investigated organic solvents except for the PBS/ACN mixture. As was proved in further studies, this phenomenon was related to the partial hydrolysis of imines, which is the source of the fluorogenic aldehyde causing the aggreggacion incrased-emision effect. In further research, due to the susceptibility of the azomethines to partial hydrolysis, the biological activity of 2-{(E)-[4-(phenylethynyl) phenyl]imino}phenol (1b), substrate (2-aminophenol) and Cu(II)-1b complex was analyzed. The biological tests showed, that 1b (as example of imine resveratrol analogue), demonstrated its increased cytostatic activity in prostate cancer cellular system. It was proved that the non-hydrolyzed imine was crucial for the cytotoxic effect. This activity could be ascribed to its Cu(II) complexing capability as showed in our previous research.

Abstract
To assess the chondroprotective effect and influence of
N,N′-bis(1,5-dimethyl-2-phenyl-1,2-dihydro-3-oxopyrazol-4-yl)
sebacamide (dpdo) that was synthesized through the reaction of phenazone with
sebacoyl chloride and screened for its biological activity especially as
anti-arthritic and anti-inflammatory agent in a monoiodoacetate (MA)-induced
experimental osteoarthritis (OA) model. Thirty male albino rats weighing
“190–200 g” were divided randomly into three groups (10 each): control,
MA-induced OA, and MA-induced OA + dpdo. In MA-induced OA rat, the tumor
necrosis factor alpha, interleukin 6, C-reactive protein, rheumatoid factors,
reactive oxygen species, as well as all the mitochondrial markers such as
mitochondria membrane potential, swelling mitochondria, cytochrome
c oxidase (complex IV), and serum oxidative/antioxidant
status (malondialdehyde level and activities of myeloperoxidase and xanthine
oxidase) are elevated. Also, the activity of succinate dehydrogenase (complex
II), levels of ATP, the level of glutathione (GSH), and thiol were markedly
diminished in the MA-induced OA group compared to the normal control rats. These
findings showed that mitochondrial function is associated with OA
pathophysiological alterations and high gene expressions of (IL-6, TNF-a, and
IL-1b) and suggests a promising use of dpdo as potential ameliorative agents in
the animal model of OA and could act as anti-inflammatory agent in case of
severe infection with COVID-19. It is clearly appeared in improving the bone
cortex and bone marrow in the treated group with the novel compound in
histological and transmission electron microscopic sections which is a very
important issue today in fighting severe infections that have significant
effects on the blood indices and declining of blood corpuscles like COVID-19, in
addition to declining the genotoxicity and inflammation induced by MA in male
rats. The novel synthesized compound was highly effective in improving all the
above mentioned parameters.

Abstract
![]()
Thiazoles,
their benzofused systems, and thiazolidinone derivatives
are widely recognized as nuclei of great value for obtaining molecules
with various biological activities, including analgesic, anti-inflammatory,
anti-HIV, antidiabetic, antitumor, and antimicrobial. In particular,
in the past decade, many compounds bearing these heterocycles have
been studied for their promising antibacterial properties due to their
action on different microbial targets. Here we assess the recent development
of this class of compounds to address mechanisms underlying antibiotic
resistance at both bacterial-cell and community levels (biofilms).
We also explore the SAR and the prospective clinical application of
thiazole and its benzofused derivatives, which act as inhibitors of
mechanisms underlying antibiotic resistance in the treatment of severe
drug-resistant infections. In addition, we examined all bacterial
targets involved in their antimicrobial activity reporting, when described,
their spontaneous frequencies of resistance.

Eur J Pharm Sci 2020; 148:105300. [PMID: 32160953 DOI: 10.1016/j.ejps.2020.105300] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2019] [Revised: 03/02/2020] [Accepted: 03/07/2020] [Indexed: 12/20/2022]
Abstract
In order to discover a new compound having anti-inflammatory activity, a nitro-Schiff base was evaluated. The compound was synthesized and characterized by 1H NMR and 13C NMR. The cytotoxic activity was evaluated in vitro by hemolysis and MTT cell viability assay. To evaluate genotoxicity, the micronucleus assay was performed in vivo. The anti-inflammatory effects of the compound were examined using in vivo models of inflammation such as neutrophil migration assay, paw edema, and exudation assay. The production of NO was also estimated in vivo and in vitro. The data showed that the compound did not induce hemolysis at all the tested concentrations. Similarly, the compound did not induce cytotoxicity and genotoxicity to the cells. The neutrophil migration assay showed that the compound reduced the number of neutrophils recruited to the peritoneal cavity by approximately 60% at all the tested concentrations. In the exudation assay, the compound showed a reduction in extravasation by 24%. The paw edema model demonstrated a significant reduction in the paw volume at all the evaluated time points. The production of NO was decreased both in vitro and in vivo. These results suggest that the nitro-Schiff base compound efficiently inhibited inflammation and might be a good candidate for the treatment of inflammatory-associated conditions.

Abstract
New series of phenolic azomethine compounds in addition to 5-arylidene thiazolidinones are synthesized and screened for their anticancer activity against the brain cancer cell line SNB-75 and non-small lung cancer cells HOP-92. The azomethine derivative 12b is the most active compound against SNB-75 displaying an IC50value of 0.14 μM. Compounds 7b, 16a and 27d display submicromolar activity against the HOP-92 cell line with IC50values of 0.73, 0.74 and 0.81 μM, respectively. Moreover, studying the cytotoxic effects of the most active compounds against normal lung cells WI-38 revealed that compounds 7b, 16a and 27d showed high safety profiles as anticancer agents.

Abstract
BACKGROUND In search of new antimicrobial and cytotoxic agents, a series of new naphthol diazenyl scaffold based Schiff bases (NS1-NS23) was efficiently synthesized by condensation of 2-hydroxy naphthaldehyde azo dyes with various substituted aromatic/heteroaromatic/aliphatic amines. METHODOLOGY The synthesized derivatives were characterized by various physicochemical and spectral techniques and assessed for in vitro antimicrobial and cytotoxic potential against human colorectal carcinoma cell line (HT-29). The active derivatives were further evaluated for their apoptotic potential by Annexin-V/propidium iodide double staining assay using flow cytometer and analyzed for cell-cycle arrest studies. RESULTS AND CONCLUSION The derivative NS-2 was found maximum active against E. coli, S. enterica and B. subtilis. The derivatives NS-12, NS-15, NS-21, and NS-23 showed maximum antifungal activity against A. fumigatus. The maximum cytotoxicity was observed from the derivatives NS-2, NS-8, NS-21, and NS-23 towards HT-29 cell line with IC50 between 4 and 19 μg/ml. More than 90% and 62% of the cells were found in the apoptotic phase on treatment with NS-2 and NS-21 respectively in comparison to the 68% for doxorubicin. Further, these derivatives arrested the cell growth in S and G2/M phase of the cell cycle.

Abstract
BACKGROUND The increasing incidence of fungal infections, especially caused by Candida albicans, and their increasing drug resistance has drastically increased in recent years. Therefore, not only new drugs but also alternative treatment strategies are promptly required. METHODS We previously reported on the synergistic interaction of some azole and non-azole compounds with fluconazole for combination antifungal therapy. In this study, we synthesized some non-azole Schiff-base derivatives and evaluated their antifungal activity profile alone and in combination with the most commonly used antifungal drugs- fluconazole (FLC) and amphotericin B (AmB) against four drug susceptible, three FLC resistant and three AmB resistant clinically isolated Candida albicans strains. To further analyze the mechanism of antifungal action of these compounds, we quantified total sterol contents in FLC-susceptible and resistant C. albicans isolates. RESULTS A pyrimidine ring-containing derivative SB5 showed the most potent antifungal activity against all the tested strains. After combining these compounds with FLC and AmB, 76% combinations were either synergistic or additive while as the rest of the combinations were indifferent. Interestingly, none of the combinations was antagonistic, either with FLC or AmB. Results interpreted from fractional inhibitory concentration index (FICI) and isobolograms revealed 4-10-fold reduction in MIC values for synergistic combinations. These compounds also inhibit ergosterol biosynthesis in a concentration-dependent manner, supported by the results from docking studies. CONCLUSION The results of the studies conducted advocate the potential of these compounds as new antifungal drugs. However, further studies are required to understand the other mechanisms and in vivo efficacy and toxicity of these compounds.

How a drug is released from a DDS is a critical issue that determines whether the DDS is designed successfully. We all know that the microenvironment of tumors is quite different from normal tissues, such as its acidic environment, different expression levels of some enzymes, etc. These features are widely used in the design of DDSs and play an important role in the drug release process in vivo. Numerous DDSs have been designed and synthesized. This article attention to how drugs are released from DDSs. We summarizes and classify the characteristic enzymes and chemical bonds used in the drug release process by browsing a large number of papers, and describes how they are applied in DDSs with specific examples. By understanding these acid-sensitive chemical bonds and over-expressed enzymes in tumors, different DDSs can be designed for different drug structures to solve specific problems of anti-tumor drugs.

Characterization of Antimicrobial, Antioxidant, and Leishmanicidal Activities of Schiff Base Derivatives of 4-Aminoantipyrine. Molecules 2019; 24:E2696. [PMID: 31344947 PMCID: PMC6696115 DOI: 10.3390/molecules24152696] [Citation(s) in RCA: 21] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2019] [Revised: 04/08/2019] [Accepted: 04/08/2019] [Indexed: 01/26/2023] Open
Abstract
Our main interest is the characterization of compounds to support the development of alternatives to currently marketed drugs that are losing effectiveness due to the development of resistance. Schiff bases are promising biologically interesting compounds having a wide range of pharmaceutical properties, including anti-inflammatory, antipyretic, and antimicrobial activities, among others. In this work, we have synthesized 12 Schiff base derivatives of 4-aminoantipyrine. In vitro antimicrobial, antioxidant, and cytotoxicity properties are analyzed, as well as in silico predictive adsorption, distribution, metabolism, and excretion (ADME) and bioactivity scores. Results identify two potential Schiff bases: one effective against E. faecalis and the other with antioxidant activity. Both have reasonable ADME scores and provides a scaffold for developing more effective compounds in the future. Initial studies are usually limited to laboratory in vitro approaches, and following these initial studies, much research is needed before a drug can reach the clinic. Nevertheless, these laboratory approaches are mandatory and constitute a first filter to discriminate among potential drug candidates and chemical compounds that should be discarded.

Abstract
BACKGROUND In this study, the antioxidant property of new synthesized azomethins has been investigated as theoretical and experimental. METHODS AND RESULTS Density functional theory (DFT) was employed to investigate the Bond Dissociation Enthalpy (BDE), Mulliken Charges, NBO analysis, Ionization Potential (IP), Electron Affinities (EA), HOMO and LUMO energies, Hardness (η), Softness (S), Electronegativity (µ), Electrophilic Index (ω), Electron Donating Power (ω-), Electron Accepting Power (ω+) and Energy Gap (Eg) in order to deduce scavenging action of the two new synthesized azomethines (FD-1 and FD-2). Spin density calculations and NBO analysis were also carried out to understand the antioxidant activity mechanism. Comparison of BDE of FD-1 and FD-2 indicate the weal antioxidant potential of these structures. CONCLUSION FD-1 and FD-2 have very high antioxidant potential due to the planarity and formation of intramolecular hydrogen bonds.

Abstract
We herein report a new small library of Schiff-base compounds that encompasses s-triazine and (2 or 4)-hydroxylbenzylidene derivatives. These compounds were synthesized through a hydrazone linkage connecting both the s-triazine and hydroxybenzylidene derivatives. The synthetic strategy adopted allowed the synthesis of the target compounds with excellent yields and purities as observed from their NMR (1H and 13C) and elemental analysis. Furthermore, 4f, 5b, and 5f were further confirmed by X-ray single crystal diffraction technique. The preliminary antiproliferative activities for the synthesized compounds were tested against two different cancer cell lines including breast cancer (MCF-7) and colon cancer (HCT-116). From the eighteen compounds, which have been examined, only two derivatives having piperidine moiety showed more selectivity against the two cell lines MCF-7 and HCT-116, while the others showed very weak activity. The position of the hydroxyl group in the benzylidine ring and the substituent on the s-triazine moiety has great effect on the activity of the prepared compounds. The IC50 values for the two derivatives 4a and 5a evaluated against breast cancer cells, very close to those for the chemotherapeutic drug cisplatin, are 27 µM (13.3 µg/mL), 17 µM (8.4 µg/mL), and 20 µM (6 µg/mL) for 4a, 5a, and cisplatin, respectively. These results propose the preliminary antiproliferative activity of these two derivatives may deserve further consideration for development of new derivatives as potent anticancer agents.

Abstract
(E)-2-(3-Hydroxy-4-methoxybenzylidene)hydrazinecarbothioamide 3 was synthesized by reacting thiosemicarbazide with 2-hydorxy-3-methoxybenzaldehyde in dry ethanol. The structure was elucidated by spectroscopic (FT-IR, 1H NMR, and 13C NMR) and single crystal X-ray diffraction techniques. A detailed analysis of the intermolecular interactions has been performed based on the Hirshfeld surfaces and their associated two-dimensional fingerprint plots. DFT, spectroscopic, and electrochemical DNA-binding analysis confirmed that the compound is reactive to bind with DNA. Viscometric studies suggested that compound 3 has a mixed mode of interaction and intercalated into the DNA base pairs predominantly along with the possibility of electrostatic interactions.

Abstract
A novel series of s-triazines incorporating 4-hydroxybenzaldehyde and 4-hydroxy-3-methoxybenzaldehyde was prepared and fully characterized. The reaction was carried out via stepwise nucleophilic aromatic substitution of chlorine atoms in cyanuric chloride. The first chlorine was substituted by different amines (morpholine, piperidine, or diethylamine) to afford 2,4-dichloro-6-substituted-1,3,5-triazine. The second and third chlorines were substituted by benzaldehyde derivatives in the presence of Na₂CO₃ as a HCl scavenger to afford the target products: s-triazine oxyaldehyde derivatives (dipodal). The dipodal derivatives were reacted with acid hydrazide, hydralazine, barbituric, or thiobarbituric acid derivatives using conventional heating or microwave irradiation to afford the di-arm s-triazine oxy-Schiff base and oxybenzylidene barbiturate derivatives in good yields. Microwave irradiation done in less solvent afforded the target product in less reaction time with good yield and purity. These types of derivatives might have special interest in coordination and medicinal chemistry.

Schiff bases of tryptamine as potent inhibitors of nucleoside triphosphate diphosphohydrolases (NTPDases): Structure-activity relationship. Bioorg Chem 2018; 82:253-266. [PMID: 30391856 DOI: 10.1016/j.bioorg.2018.10.046] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2018] [Revised: 10/18/2018] [Accepted: 10/23/2018] [Indexed: 01/10/2023]
Abstract
Overexpression of NTPDases leads to a number of pathological situations such as thrombosis, and cancer. Thus, effective inhibitors are required to combat these pathological situations. Different classes of NTPDase inhibitors are reported so far including nucleotides and their derivatives, sulfonated dyes such as reactive blue 2, suramin and its derivatives, and polyoxomatalates (POMs). Suramin is a well-known and potent NTPDase inhibitor, nonetheless, a range of side effects are also associated with it. Reactive blue 2 also had non-specific side effects that become apparent at high concentrations. In addition, most of the NTPDase inhibitors are high molecular weight compounds, always required tedious chemical steps to synthesize. Hence, there is still need to explore novel, low molecular weight, easy to synthesize, and potent NTPDase inhibitors. Keeping in mind the known NTPDase inhibitors with imine functionality and nitrogen heterocycles, Schiff bases of tryptamine, 1-26, were synthesized and characterized by spectroscopic techniques such as EI-MS, HREI-MS, 1H-, and 13C NMR. All the synthetic compounds were evaluated for the inhibitory avidity against activities of three major isoforms of NTPDases: NTPDase-1, NTPDase-3, and NTPDase-8. Cumulatively, eighteen compounds were found to show potent inhibition (Ki = 0.0200-0.350 μM) of NTPDase-1, twelve (Ki = 0.071-1.060 μM) of NTPDase-3, and fifteen compounds inhibited (Ki = 0.0700-4.03 μM) NTPDase-8 activity. As a comparison, the Kis of the standard inhibitor suramin were 1.260 ± 0.007, 6.39 ± 0.89 and 1.180 ± 0.002 μM, respectively. Kinetic studies were performed on lead compounds (6, 5, and 21) with human (h-) NTPDase-1, -3, and -8, and Lineweaver-Burk plot analysis showed that they were all competitive inhibitors. In silico study was conducted on compound 6 that showed the highest level of inhibition of NTPDase-1 to understand the binding mode in the active site of the enzyme.

Abstract
Schiff bases, an aldehyde- or ketone-like compounds in which the carbonyl group is replaced by an imine or azomethine, are some of the most widely used organic compounds. Indeed, they are widely used for industrial purposes and also exhibit a broad range of biological activities, including anti-urease activity. Ureases, enzymes that catalyze urea hydrolysis, have received considerable attention for their impact on living organisms’ health, since the persistence of urease activity in human and animal cells can be the cause of some diseases and pathogen infections. This short review compiles examples of the most antiurease Schiff bases (0.23 μM < IC50 < 37.00 μM) and their metal complexes (0.03 μM < IC50 < 100 μM). Emphasis is given to ureases of Helicobacter pylori and Canavalia ensiformis, although the active site of this class of hydrolases is conserved among living organisms.

Abstract
In recent years, the number of people suffering from cancer and multidrug-resistant infections has sharply increased, leaving humanity without any choice but to search for new treatment options and strategies. Although cancer is considered the leading cause of death worldwide, it also paves the way many microbial infections and thus increases this burden manifold. Development of small molecules as anticancer and anti-microbial agents has great potential and a plethora of drugs are already available to combat these diseases. However, the wide occurrence of multidrug resistance in both cancer and microbial infections necessitates the development of new and potential molecules with desired properties that could circumvent the multidrug resistance problem. A successful strategy in anticancer chemotherapy has been the use of metallo-drugs and this strategy has the potential to be used for treating multidrug-resistant infections more efficiently. As a class of molecules, Schiff bases have been the topic of considerable interest, owing to their versatile metal chelating properties, inherent biological activities and flexibility to modify the structure to fine-tune it for a particular biological application. Schiff base-based metallo-drugs are being researched to develop new anticancer and anti-microbial chemotherapies and because both anticancer and anti-microbial targets are different, heterocyclic Schiff bases can be structurally modified to achieve the desired molecule, targeting a particular disease. In this review, we collect the most recent and relevant literature concerning the synthesis of heterocyclic Schiff base metal complexes as anticancer and anti-microbial agents and discuss the potential and future of this class of metallo-drugs as either anticancer or anti-microbial agents.

Abstract
The global spread of bacterial resistance to drugs used in therapy requires new potent and safe antimicrobial agents. DNA gyrases represent important targets in drug discovery. Schiff bases, thiazole, and triazole derivatives are considered key scaffolds in medicinal chemistry. Fifteen thiazolyl-triazole Schiff bases were evaluated for their antibacterial activity, measuring the growth inhibition zone diameter, the minimum inhibitory concentration (MIC), and the minimum bactericidal concentration (MBC), against Gram-positive (Staphylococcus aureus, Listeria monocytogenes) and Gram-negative (Escherichia coli, Salmonella typhimurium, Pseudomonas aeruginosa) bacteria. The inhibition of S. aureus and S. typhimurium was modest. Compounds B1, B2, and B9 showed a similar effect as ciprofloxacin, the antimicrobial reference, against L. monocytogenes. B10 displayed a better effect. Derivatives B1, B5–7, B9, and B11–15 expressed MIC values lower than the reference, against L. monocytogenes. B5, B6, and B11–15 strongly inhibited the growth of P. aeruginosa. All compounds were subjected to an in silico screening of the ADMET (absorption, distribution, metabolism, elimination, toxicity) properties. Molecular docking was performed on the gyrA and gyrB from L. monocytogenes. The virtual screening concluded that thiazolyl-triazole Schiff base B8 is the best drug-like candidate, satisfying requirements for both safety and efficacy, being more potent against the bacterial gyrA than ciprofloxacin.

Abstract
Thirty-nine Schiff bases were synthesized by performing microwave-assisted condensation of the corresponding aldehydes and aromatic amines. Their reactive nitrogen species (RNS) scavenging activity and inhibitory effects against cancer cell growth were then subsequently investigated. Additionally, the interaction between the calf thymus DNA (ctDNA) and selected Schiff bases was evaluated using fluorescence spectroscopy, and their binding parameters were determined. The yields of the various compounds ranged from moderate to excellent (43-99%) after only a 2-min reaction. The hydroxylated Schiff bases 2, 8, 15, 16, 18, 20, 29, 32, 34, and 37 were found to be potent scavengers of 2,2-diphenyl-1-picrylhydrazyl (DPPH) radicals with half-maximal scavenging concentration (SC50) values lower than that of the positive control, resveratrol. The presence of hydroxyl substituents on the aromatic rings also proved essential to the cytotoxicity of the compounds. The binding constants (Kb) obtained using fluorescence spectroscopy ranged from 0.37 to 3.07×105Lmol-1, and were strongly influenced by the structure and hydroxylation degree. Schiff bases 3 and 8 showed promising cytotoxic activity, with half-maximal growth inhibitory (GI50) values in the same order of magnitude as those exhibited by the reference drug, doxorubicin against various cell lines. Interestingly, these compounds also showed the highest Kb, suggesting that the cytotoxic activity could be related to their interaction with the DNA of the tumor cells. The results of this study highlighted some Schiff bases as potential lead compounds for the design of new free radical scavengers and anticancer agents.
