Diversity-Oriented Synthesis of Thiazolidine-2-imines via Microwave-Assisted One-Pot, Telescopic Approach and Its Interaction with Biomacromolecules

In this work, a one-pot, telescopic approach is described for the combinatorial library of thiazolidine-2-imines. The synthetic manipulation proceeds smoothly via the reaction of 2-aminopyridine/pyrazine/pyrimidine with substituted isothiocyanates followed by base catalyzed ring closure with 1,2-dibromoethane to obtain thiazolidine-2-imines with broad substrate scope and high functional group tolerance. The synthetic strategy merges well with the thiourea formation followed by base catalyzed ring closure reaction for the thiazolidine-2-imine synthesis in a more modular and straightforward approach. The synthetic procedure reported herein represents a cleaner route toward thiazolidine-2-imines as compared to traditional methodologies. Moreover, the biological significance of combinatorially synthesized thiazolidin-2-imines has been investigated for their use as possible inhibitors for acetyl cholinesterase through molecular docking studies.

Intracellular distribution of new tacrine analogues as a potential cause of their cytotoxicity against human neuroblastoma cells SH-SY5Y

Four new glyco-conjugated tacrine derivatives, 4-(2,3,4,6-tetra-O-acetyl–D-glucopyranosyl)-1-(1,2,3,4-tetrahydroacridin-9-yl)thiosemicarbazide (1), 4-(2,3,4,6-tetra-O-acetyl–D-mannopyranosyl)-1-(1,2,3,4-tetrahydroacridin-9-yl)thiosemicarbazide (2), 2-(1,2,3,4-tetrahydroacridin-9-yl)hydrazono-3-(2,3,4,6-tetra-O-acetyl–D-galactopyranosyl)-1,3-thiazolidin-4-one (3) and [2-(1,2,3,4-tetrahydro-acridin-9-yl)hydrazono-3-(2,3,4,6-tetra-O-acetyl–D-glucopyranosyl)-4-oxothiazolidin-5-yliden]acetate (4) were synthesized and their characteristics were investigated. All of the novel derivatives were found to inhibit acetylcholinesterase obtained from Electrophorus electricus at a magnitude of one order less than that of the control tacrine. Derivatives 1-3 were found to be nontoxic towards human neuroblastoma SH-SY5Y cells, while compound 4 was markedly cytotoxic against these cells (IC50 value 2 mu M, 72h). These differences in cytotoxicity were examined further by investigating the uptake and intracellular localization of the tacrine derivatives. Non-cytotoxic derivatives 1-3 were found to localize outside of the nuclei, showing a marked preference for the lysosomes and the mitochondria; in contrast, the cytotoxic derivative 4 was localized in the nuclei of the neuroblastoma cells. Interaction studies revealed that derivative 4 displays a high affinity towards DNA, and also provided evidence of the compound’s ability to inhibit Topo I.

Construction of Cu-bridged Cu2O/MIL(Fe/Cu) catalyst with enhanced interfacial contact for the synergistic photo-Fenton degradation of thiacloprid

Cu2O/MIL(Fe/Cu) composite was fabricated via an in-situ Cu-bridging strategy to enhance interfacial synergistic effect of photo-Fenton catalysis for thiacloprid (TCL) degradation. Characterization results showed that: (1) Cu2O was proved to grow on the surface of MIL(Fe/Cu) in Cu2O/MIL(Fe/Cu) composite and display a high BET surface area of 1553 m(2)/g; (2) Cu2O/MIL(Fe/Cu) reduced band gap from 2.5 to 1.3 eV and extended absorption from UV to visible region; (3) Cu-bridge was proved to promote the intimate interface between Cu2O and MIL (Fe/Cu), which accelerated charge transferred and shortened the binding gap and the reaction pathway from photo-induced electrons to Fenton-generated radicals. As a result, this boosted the redox reaction of Fe2+/Fe3+ and promoted the reversible degree of this catalytic redox ability of MIL(Fe). Catalytic performance exhibited that (1) Cu2O/MIL(Fe/Cu) showed a fast kinetics (2-40 times faster than the state-of-the-art catalysts) and ultrahigh mineralization (82.3% within 80 min) for TCL degradation; (2) Cu2O/MIL(Fe/Cu) showed a promising cycling stability due to improved charge transfer ability that could protect Cu2O from photo-corrosion during photo-Fenton reaction; (3) The catalytic performance of Cu2O/MIL(Fe/Cu) was characterized and seven photocatalytic intermediates were identified by both HPLC/MS and Surface Enhanced Raman Spectroscopy. The cyanoimino group in TCL was proved for the first time to be attacked primarily. Moreover, among all the detected intermediates, thiazolidin-2-amine (P6) was found to be the most stable intermediate to be degraded, and it can directly influence the TOC determination during photodegradation process.

Molecular Docking, Molecular Dynamics, and In Silico Prediction of the Toxic Potential of Primaquine Thiazolidinone Derivatives

Backkground: Primaquine thiazolidinone derivatives are proposed as promising antimalarial candidates to be tested as primaquine substitutes. Method: Molecular docking and dynamics simulations were applied in the analogues-NQO2 complexes to understand their interactions, and the toxic potential of these derivatives in a set of 16 target proteins was also studied. Results: The results of our study suggest that the interactions of five thiazolidinone primaquine derivatives with NQO2 are stronger than the interaction of primaquine and NQO2. The analogue 5n-protein complex seems to be the most stable compared with the primaquine-protein complex. The analogues 5n and 5o are predicted to be in the same class of toxic potential as primaquine. Conclusion: Their interactions with the cytochrome P450 enzymes are also predicted to be weaker, indicating that a better activity/toxicity balance compared with primaquine may be reached.

Antimicrobial activity of some novel 2-( 2-iodophenylimino)-5-arylidenethiazolidin-4-one derivatives

Background: Infectious diseases, especially those caused by multidrug-resistant bacteria, are becoming a serious problem worldwide because of the lack of effective therapeutic agents. Moreover, most antifungal drugs exhibit low efficacy and high toxicity because of the similarity between fungal and human cells. These issues warrant the search for potential new agents. Objectives: To synthesize potent 2-(2-iodophenylimino)-5-arylidenethiazolidin-4-one derivatives, improve the synthetic process, elucidate their structures, and determine their antimicrobial activity. Methods: 2- Iodoaniline was used as an initial reactant in a 3-step process for the synthesis of 2-(2-iodophenylimino)5-arylidenethiazolidin-4-one derivatives, including an acylation reaction, a cyclization reaction, and aldol condensation reactions. The structures of the obtained derivatives were investigated and elucidated using spectral methods. Antimicrobial activity toward 5 bacterial strains and 2 fungal strains was determined using Kirby-Bauer and agar dilution methods. Results: We successfully synthesized 12 novel compounds and elucidated their structures. The derivatives had no antifungal activities. By contrast, they showed remarkable antibacterial activities. Some of them with minimum inhibitory concentrations (MICs) <= 8 mu g/mL in both Staphylococcus aureus and methicillin-resistant S. aureus. Conclusions: A simple and flexible way to synthesize new compounds with a thiazolidin-4-one ring was determined. Some of these new compounds have outstanding effects with low MICs for bacteria. Their further investigation as therapeutic agents is warranted.
