Novel 1,3-thiazolidin-4-one derivatives as promising anti-Candida agents endowed with anti-oxidant and chelating properties

Pursuing our recent outcomes regarding the antifungal activity of N-substituted 1,3-thiazolidin-4-ones, we synthesized thirty-six new derivatives introducing aliphatic, cycloaliphatic and heteroaromatic moieties at N1-hydrazine connected with C2 position of the thiazolidinone nucleus and functionalizing the lactam nitrogen with differently substituted (NO2, NH2, Cl and F) benzyl groups. These compounds were tested to evaluate their minimum inhibitory concentration (MIC) against several clinical Candida spp. with respect to topical and systemic reference drugs (clotrimazole, fluconazole, ketoconazole, miconazole, tioconazole, amphotericin B). Moreover, anti-oxidant properties were also evaluated by using different protocols including free radical scavenging (DPPH and ABTS), reducing power (CUPRAC and FRAP), metal chelating and phosphomolybdenum assays. Moreover, for the most active derivatives we assessed the toxicity (CC50) against Hep2 human cells in order to characterize them as multi-target agents for fungal infections.

Alignment independent 3D-QSAR studies and molecular dynamics simulations for the identification of potent and selective S1P(1) receptor agonists

Sphingosine 1-phosphate type 1 (S1P(1)) receptors are expressed on lymphocytes arid regulate immune cells trafficking. Sphingosine 1-phosphate and its analogues cause internalization and degradation of SiP1 receptors, preventing the auto reactivity of immune cells in the target tissues. It has been shown that S1 Pi receptor agonists such as fingolimod can be suitable candidates for treatment of autoimmune diseases. The current study aimed to generate GRIND-based 3D-QSAR predictive models for agonistic activities of 2-imino-thiazolidin-4-one derivatives on S1P(1) to be used in virtual screening of chemical libraries. The developed model for the SiP1 receptor agonists showed appropriate power of predictivity in internal (r(acc)(2), 0.93 and SDEC 0.18) and external (r(2) 0.75 and MAE (95% data), 0.28) validations. The generated model revealed the importance of variables DRY-N1 and DRY-O in the potency and selectivity of these compounds towards SI Pi receptor. To propose potential chemical entities with S1P(1) agonistic activity, PubChem chemicals database was searched and the selected compounds were virtually tested for S1P(1) receptor agonistic activity using the generated models, which resulted in four potential compounds with high potency and selectivity towards S1P(1) receptor. Moreover, the affinities of the identified compounds towards S1P(1) receptor were evaluated using molecular dynamics simulations. The results indicated that the binding energies of the compounds were in the range of -39.31 to -46.18 and -3.20 to -9.75 kcal mol(-1), calculated by MM-GBSA and MM-PBSA algorithms, respectively. The findings in the current work may be useful for the identification of potent and selective S1P(1) receptor agonists with potential use in diseases such as multiple sclerosis.

Benzothiazole incorporated thiazolidin-4-ones and azetidin-2-ones derivatives: Synthesis and in vitro antimicrobial evaluation

In this study, a series of novel thiazolidin-4-ones (5a-g) and azetidin-2-ones (6a-g) were synthesized from N-(6-chlorobenzo[d]thiazol-2-yl)hydrazine carboxamide derivatives of the benzothiazole class. Antimicrobial properties of the title compound derivatives were investigated against one Gram (+) bacteria (Staphylococcus aureus), three Gram (-) bacteria (Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae) and five fungi (Candida albicans, Aspergillus niger, Aspergillus flavus, Monascus purpureus and Penicillium citrinum) using serial plate dilution method. The investigation of antibacterial and antifungal screening data revealed that all the tested compounds showed moderate to good inhibition at 12.5-200 lg/mL in DMSO. It has been observed that azetidin-2-ones derivatives are found to be more active than thiazolidin-4-ones derivatives against all pathogenic bacterial and fungal strains.

Unexpected complexation of allylpseudothiohydantoin hydrochlorides towards CuX (X=Cl, NO3, ClO4, BF4, 1/2SiF(6)). The first known examples of joint Cu-I(Cl,ClO4) and Cu-I(Cl,BF4) -complexes

By means of alternating current-electrochemical synthesis starting from a mixture of 2-imino-3-(prop-2-en-1-yl)-1,3-thiazolidin-4-one (3-allylpseudothiohydantoin, napt) and 2-allylamino-1,3-thiazol-4(5H)-one (allylaminopseudothiohydantoin, aapt) hydrochlorides and corresponding copper(II) salts five new -complexes, [Cu(napt)Cl] (1), [Cu-2(aapt)(2)Cl]NO3 (2), [Cu-2(aapt)(2)Cl]BF4 (3), [Cu-2(aapt)(2)Cl]ClO4 (4) and [Cu-2(aapt)(2)Cl](2)SiF(6)2H(2)O (5), were obtained and studied by X-ray single crystal diffraction and IR-spectroscopy. Napt and aapt molecules are selectively coordinated to Cu+ depending on the anion type. In crystals of 1 and 5, the organic ligands are attached to the metal in a chelating N,(C=C)-bidentate mode. The aapt molecule in 2-4 acts as a tridentate chelating ligand, being coordinated to the copper(I) ion through the heterocyclic N atom, carbonyl O atom, and C=Cbond of allyl group, forming an original cationic [Cu-2(aapt)(2)Cl](+) fragment with both a bridging Cl- ion and O atom of the C=O group. In the presence of the doubly charged SiF62- anion, Cu(I) in 5 prefers to be bonded with two bridging Cl- ions, rather than the C=O group, causing [Cu-2(aapt)(2)Cl](+) units to associate into the infinite cationic chains. Crystals of 3 and 4 are the first known examples of the simultaneous BF4-/Cl- or ClO4-/Cl- participation in copper(I) -complex formation. [GRAPHICS]

Preparation and characterization of Fe3O4@SiO2/APTPOSS core-shell composite nanomagnetics as a novel family of reusable catalysts and their application in the one-pot synthesis of 1,3-thiazolidin-4-one derivatives

Octakis[3-(3-aminopropyltriethoxysilane)propyl]octasilsesquioxane (APTPOSS) as a polyhedral oligomeric silsesquioxane derivative was prepared and used as a pioneer reagent to obtain a novel core-shell composite using magnetic iron oxide nanoparticles as the core and the inorganic-organic hybrid polyhedral oligomeric silsesquioxane as the shell. Fe3O4@SiO2/APTPOSS were confirmed using Fourier transform infrared spectroscopy, scanning electron microscopy, energy dispersive spectroscopy, dynamic light scattering, thermogravimetric analysis, X-ray diffraction and vibrating sample magnetometry. The inorganic-organic hybrid polyhedral oligomeric silsesquioxane magnetic nanoparticles were used as an efficient new heterogeneous catalyst for the onepot three-component synthesis of 1,3-thiazolidin-4-ones under solvent-free conditions. Moreover, these nanoparticles could be easily separated using an external magnet and then reused several times without significant loss of catalytic activity.

Phytochemical profiling and effect of Andrographis echioides (L.) Nees leaf extract on glucose uptake by 3T3-L1 cell lines – An in vitro study

The human population worldwide appears to be in the midst of an epidemic of diabetes, a metabolic disorder characterised by problems in carbohydrate metabolism. The existing synthetic drugs have several limitations such as, diabetic retinopathy, nephropathy and neuropathy. Thus, in spite of remarkable progress in the treatment of diabetes by oral hypoglycemic agents, search for newer drugs continues. Hence, in the present study, Andrographis echioides (L.) Nees was examined for its in vitro antidiabetic efficacy by amylase inhibition and glucose uptake by 3T3 cell lines assays. In addition, the bioactive components were analysed by GC-MS technique. The data obtained suggests that methanol extract of A. echioides was effective in enhancing glucose uptake by the 3T3 cell lines in vitro. The GC-MS profile revealed the presence of 5-ethyl-2-imino thiazolidin-4-one recorded at 15.95min. Literature survey has proved that thiazolidin-4-one derivatives have important biological activities and thus, the antidiabetic potential of A. echioides can be related to its presence. Further mechanistic studies could be taken up to prove the effect in vivo.

Further insight into the dual COX-2 and 15-LOX anti-inflammatory activity of 1,3,4-thiadiazole-thiazolidinone hybrids: The contribution of the substituents at 5th positions is size dependent

Herin we report the design, synthesis, full characterization and biological investigation of new 15-LOX/COX dual inhibitors based on 1,3-thiazolidin-4-one (15-lipoxygenase pharmacophore) and 1,3,4-thiadiazole (COX pharmacophore) scaffolds. This series of molecular modifications is an extension of a previously reported series to further explore the structural activity relationship. Compounds 3a, 4e, 4n, 4q, 7 and 8 capable of inhibiting 15-LOX at (2.74, 4.2, 3.41, 10.21, 3.71 and 3.36 mu M, respectively) and COX-2 at (0.32, 0.28, 0.28, 0.1, 0.28 and 0.27 mu M, respectively). The results revealed that binding to 15-LOX and COX is sensitive to the bulkiness of the substituents at the 5 positions. 15-LOX bind better with small substituents, while COXs bind better with bulky substituents. Compounds 3a, 4r and 4q showed comparable in vivo anti-inflammatory activity to the reference drug (celecoxib). The ulcer liability test showed no sign of ulceration which ensures the safe gastric profile. Docking study was performed to explore the possible mode of interaction of the new compounds with the active site of human 15-LOX and COX-2. This study discloses some structural features for binding to 15-LOX and COX, thus pave the way to design anti-inflammatory agents with balanced dual inhibition of these enzymes.
