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]

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.

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.

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.

Synthesis of thiazolidin-4-ones and thiazinan-4-ones from 1-(2-aminoethyl)pyrrolidine as acetylcholinesterase inhibitors

The present study describes the synthesis of a novel series of thiazolidin-4-one and thiazinan-4-one using 1-(2-aminoethyl)pyrrolidine as amine precursor. All compounds were synthesised by one-pot three component cyclocondensation reaction from the amine, a substituted benzaldehyde and a mercaptocarboxylic acid. The compounds were obtained in moderate to good yields and were identified and characterised by H-1, C-13?, 2?D NMR and GC/MS techniques. The compounds also were screened for their in vitro acetylcholinesterase (AChE) activity in hippocampus and cerebral cortex on Wistar rats. The six most potent compounds have been investigated for their cytotoxicity by cell viability assay of astrocyte primary culture, an important cell of central nervous system. We highlighted two compounds (6a and 6k) that had the lowest IC50 in hippocampus (5.20 and 4.46??M) and cerebral cortex (7.40 and 6.83??M). These preliminary and important results could be considered a starting point for the development of new AChE inhibitory agents.

Synthesis and Crystal Structures of Some Pyridyl Aminothiazole and Thiazolidin-2-ylidene Benzamide Derivatives

Background: Thiazoles and their derivatives are attracting continuing interest over the years because of their varied biological activities. Thiazole and in particular the 2-amino thiazole moiety has been incorporated into a wide variety of therapeutically interesting candidates including antibacterial, anti-HIV, hypertension, anti-inflamenmatory, anti-viral and anticancer agents. Methods: Several methods for the synthesis of thiazole derivatives have been developed. The most widely used method being the Hantzch’s synthesis. In this paper, we describe an efficient one-pot method for the synthesis of some thiazolidin-2-ylidene benzamide and aminothiazole derivatives via condensation of 3-aminopyridine or 2-aminopyridine with phenacyl bromide and benzoyl isothiocyanates. Results: The reaction of 3-aminopyridine, benzoyl isothiocyanates, and phenacyl bromide in the presence of triethylamine yields thiazolidin-2-ylidene benzamides, which upon heating in acetic acid produce pyridyl aminothiazole derivatives. Also the pyridyl aminothiazole derivatives were obtained by the reaction of 2-aminopyridine with benzoyl isothiocyanates and phenacyl bromide in the presence of triethylamine. The molecular structures of the 4-chloro-N-(4-hydroxy-4-phenyl-3-(pyridin-3-yl)thiazolidin-2-ylidene)benzamide, phenyl(4-phenyl-2-(pyridin-3-ylamino)thiazol-5-yl)methanone and (4-phenyl-2-(pyridin-2-yl amino)thiazol-5-yl)(o-tolyl)methanone, have been fully determined by means of single crystal Xray diffraction methods. Conclusion: In summary, present study reports one-pot synthesis of thiazolidin-2-ylidene substituted benzamide and pyridyl aminothiazole derivatives via condensation of 3-aminopyridine or 2-aminopyridine with phenacyl bromide and substituted benzoyl isothiocyanates. The single crystal X-Ray diffraction analysis reveals unequivocally the exact identity of the compounds.
