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.

Synthesis and docking studies of pyrazine-thiazolidinone hybrid scaffold targeting dormant tuberculosis

The persistence of Mycobacterium tuberculosis (MTB) in dormant stage assists the pathogen to develop resistance against current antimycobactrial drugs. To address this issue, we report herein the synthesis of N-(4-oxo-2 substituted thiazolidin-3yl) pyrazine-2-carbohydrazide derivatives designed by following the molecular hybridization approach using pyrazine and thiazolidenone scaffolds. The compounds were evaluated against MTB H37Ra and Mycobacterium bovis BCG in dormancy model. Most of the compounds had IC50 values in 0.3-1 mu g/ml range. The active compounds were further tested for anti-proliferative activity against THP-1, Panc-1, A549, and MCF-7 cell lines using MTT assay and exhibited no significant cytotoxicity. We also report molecular docking studies using active analogs and MTB Decaprenylphosphoryl-beta-D-ribose-2′-epimerase (DprE1) to rationalize the biological activity and to provide an insight into the probable mechanism of action and binding mode of hybridized structures. The results obtained validate the use of molecular hybridization approach and also suggest that reported compounds can provide a novel pharmacophore to synthesize lead compounds against dormat MTB.

[3+2]-Annulation of Azaoxyallyl Cations and Thiocarbonyls for the Assembly of Thiazolidin-4-ones

A base-promoted, efficient [3 + 2] annulation between azaoxyallyl cations and thiocarbonyls is reported for flexible access to highly functionalized thiazolidin-4-one derivatives in good to excellent yields. An intriguing feature of this method is the metal or Lewis acid free late-stage entry of distinct set of functional groups at C2 of thiazolidin-4-ones via substitution of a latent amino functional group. Overall, this approach constitutes a general platform for convenient access to this medicinally important scaffold.

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.

Characterization of an Indole-3-Acetamide Hydrolase from Alcaligenes faecalis subsp parafaecalis and Its Application in Efficient Preparation of Both Enantiomers of Chiral Building Block 2,3-Dihydro-1,4-Benzodioxin-2-Carboxylic Acid

Both the enantiomers of 2,3-dihydro-1,4-benzodioxin-2-carboxylic acid are valuable chiral synthons for enantiospecific synthesis of therapeutic agents such as (S)-doxazosin mesylate, WB 4101, MKC 242, 2,3-dihydro-2-hydroxymethyl-1,4-benzodioxin, and N-[2,4-oxo-1,3-thiazolidin-3-yl]-2,3-dihydro-1,4-benzodioxin-2-carboxamide. Pharmaceutical applications require these enantiomers in optically pure form. However, currently available methods suffer from one drawback or other, such as low efficiency, uncommon and not so easily accessible chiral resolving agent and less than optimal enantiomeric purity. Our interest in finding a biocatalyst for efficient production of enantiomerically pure 2,3-dihydro-1,4-benzodioxin-2-carboxylic acid lead us to discover an amidase activity from Alcaligenes faecalis subsp. parafaecalis, which was able to kinetically resolve 2,3-dihydro-1,4-benzodioxin-2-carboxyamide with E value of >200. Thus, at about 50% conversion, (R)-2,3-dihydro-1,4-benzodioxin-2-carboxylic acid was produced in >99% e.e. The remaining amide had (S)configuration and 99% e.e. The amide and acid were easily separated by aqueous (alkaline)-organic two phase extraction method. The same amidase was able to catalyse, albeit at much lower rate the hydrolysis of (S)-amide to (S)-acid without loss of e.e. The amidase activity was identified as indole-3-acetamide hydrolase (IaaH). IaaH is known to catalyse conversion of indole-3-acetamide (IAM) to indole-3-acetic acid (IAA), which is phytohormone of auxin class and is widespread among plants and bacteria that inhabit plant rhizosphere. IaaH exhibited high activity for 2,3-dihydro-1,4-benzodioxin-2-carboxamide, which was about 65% compared to its natural substrate, indole-3-acetamide. The natural substrate for IaaH indole-3-acetamide shared, at least in part a similar bicyclic structure with 2,3-dihydro-1,4-benzodioxin-2-carboxamide, which may account for high activity of enzyme towards this un-natural substrate. To the best of our knowledge this is the first application of IaaH in production of industrially important molecules.
