Incorporation of thiazolothiazole fluorophores into a MOF structure: A highly luminescent Zn(II)-based MOF as a selective and reversible sensor for Cr2O72- and MnO4- anions

A highly luminescent Zn-II-MOF, [Zn-2 (TzTz)(2)(BDC)(2)]-2DMF, TzTz = 2,5-di (4-pyridyl)thiazolo I (Liu a al., 2019; Shen a al., 2018) [4,5]-d] thiazole and BDC = terephthalic acid), has been solvothermally assembled and fully characterized by single crystal X-ray crystallography, elemental analysis, FT-IR spectroscopy and X-ray diffraction (XRD). This transition-metal based luminescent MOF exhibits strong blue emission while capable as a selective sensor for detection of anions. Only trace amounts of fluorescent MOF can act as a highly selective and recyclable luminescent probe for the quantitative detection of Cr-VI and Mn-VII (Cr2O72-, MnO4-) : 4 anions in aqueous solutions with large quenching constants (9 x 10(7) M-1 and 4.8 x 10(3) M-1 for Cr2O72- and MnO4-) via an energy-transfer mechanism. The first sensing study of a TzTz-functionalized MOF material demonstrates the highest sensing ability among the previously reported fluorescent MOFs with detection limits for Cr2O72- and MnO4- ions in drinking water as low as 4 mu M (100 ppb).

Synthesis, Docking and Anti-cancerous Activity of Some Novel Thiazole Derivatives of Biological Interest

Objectives: Heterocyclic compounds are enormously widespread in nature and have attracted research interest because of their pharmaceutical and biological properties. Amongst the heterocyclic rings, the thiazoles are the most important building blocks in today’s drug discovery and are found to have extensive biological activities against different types of diseases. Many potent anti-cancerous drugs like Tiazofurin are having 1,3 thiazole as an active ring structure and based on this theory, a new series of 2, 4 di substituted 1,3 thiazole derivatives were synthesized. Methods: First 2-amino-4-substituted phenyl thiazoles were synthesized by adapting a well-known Hantzsch reaction and subsequently 2-amino substituted derivatives were synthesized using various aryl aldehydes by following established Schiff’s reaction. The synthesized compounds were confirmed by TLC, IR, HNMR, CNMR and Mass Spectral Analysis. Then all the synthesized compounds were docked to RAS p21 receptor using PATCH DOCK Software to study their anti-cancerous activity. Then the compounds were screened for cancer cell line studies. Results: All the synthesized compounds exhibited some degree of anti-cancerous activity both in docking studies and in vitro anti-cancerous cell line studies. Conclusion: Amongst all the 16 synthesized, most compounds showed moderate to good anti-cancerous activity and the compounds S3P1c, S3P2c, S3P2d, S3P3a and S3P4d have shown the best activity.

Synthesis and biological evaluation of thiazole derivatives on basic defects underlying cystic fibrosis

Cystic fibrosis is a genetic disease caused by loss-of-function mutations in the cystic fibrosis transmembrane conductance regulator gene, encoding for CFTR protein. The most frequent mutation is the deletion of phenylalanine at position 508 (F508del), which leads to distinct defects in channel gating and cellular processing. In last years, several thiazole containing small molecules, endowed with dual F508del-CFTR modulator activity, proved to be able to target these defects. In search of new chemical entities able to restore CFTR function, we designed and synthesized a small series of sixteen thiazole derivatives. The designed compounds were studied as correctors and potentiators of F508del-CFTR. Although none of the molecules showed significant corrector activity, compounds 10 and 11 exhibited potentiator effects, thus allowing to determine some basic structural features which enable to obtain F508del-CFTR potentiator activity. In silico ADME studies showed that these derivatives obey Lipinski’s rule of five and are expected to be orally bioavailable. Therefore, these molecules may represent a good starting point for the design of analogues endowed with improved CFTR potentiator activity and a good pharmacokinetic profile.

Stereoisomerization of human constitutive androstane receptor agonist CITCO

CITCO (6-(4-chlorophenyl)imidazo[2,1-b][1,3]thiazole-5-carbaldehyde-O-(3,4-dichlorobenzyl) oxime) is a widely used agonist of the human constitutive androstane receptor (hCAR), a key hepatic xenobiotic sensor protein with emerging therapeutic indications. To address the insufficient stability of CITCO, which limits its therapeutic potential, the E- and Z-isomers of CITCO were synthesized and characterized by X-ray crystallography, one- and two-dimensional NMR spectroscopy. The two isomers were found to undergo E/Z isomerizations in solution likely via a protonation-rotation mechanism, time- and concentration-dependently. Our molecular modeling studies suggests both stereoisomers can bind to hCAR. (C) 2020 Elsevier Ltd. All rights reserved.

The Bronsted Basicities of N-Heterocyclic Olefins in DMSO: An Effective Way to Evaluate the Stability of NHO-CO2 Adducts

A Bronsted basicity scale (similar to 24 pK units) for 85 commonly seen imidazole-, imidazoline-, triazole-, and thiazole-based N-heterocyclic olefins (NHOs) in DMSO was established using a well-examined computational model. The influence of substituents on the BrOnsted basicities of these NHOs was investigated through basicity comparisons and rationalized by geometric analyses. The Gibbs energy (Delta G(r)) of the reaction between NHO and CO2 was also calculated, which linearly correlates with the basicity of the corresponding NHO, suggesting that the stability of NHO-CO2 adducts can be evaluated by the basicity of NHOs and a stronger basicity leads to a more stable NHO-CO2 adduct.

New Substituted 5-Benzylideno-2-Adamantylthiazol[3,2-b][1,2,4]Triazol-6(5H)ones as Possible Anti-Inflammatory Agents

Background: Inflammation is a complex response to noxious stimuli promoted by the release of chemical mediators from the damaged cells. Metabolic products of arachidonic acid, produced by the action of cyclooxygenase and lipoxygenase, play important roles in this process. Several non-steroidal anti-inflammatory drugs act as cyclooxygenase inhibitors. However, almost all of them have undesired side effects. Methods: Prediction of the anti-inflammatory action of the compounds was performed using PASS Program. The anti-inflammatory activity was evaluated by the carrageenan paw edema test. COX and LOX inhibitory actions were tested using ovine COX-1, human recombinant COX-2 and soybean LOX-1, respectively. Docking analysis was performed using Autodock. Results: All designed derivatives had good prediction results according to PASS and were synthesized and experimentally evaluated. The compounds exhibited in vivo anti-inflammatory action with eleven being equal or better than indomethacin. Although, some of them had no or low inhibitory effect on COX-1/2 or LOX, certain compounds exhibited COX-1 inhibition much higher than naproxen and COX-2 inhibition, well explained by Docking analysis. Conclusions: A number of compounds with good anti-inflammatory action were obtained. Although, some exhibited remarkable COX inhibitory action this activity did not follow the anti-inflammatory results, indicating the implication of other mechanisms.

High performance compatible thiazole-based polymeric blend cellulose acetate membrane as selective CO2 absorbent and molecular sieve

Green blend membranes comprise of high thermal resistance ortho-linked thiazole-based polyimine (PM-4) including thioether linkage were fabricated in combination of glassy cellulose acetate (CA). The thermal stabilities of PMs were examined using thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). Morphological aspects and functional groups of the membranes were investigated via field emission scanning electron microscopy (FESEM) and Fourier transform infrared spectroscopy-attenuated total reflectance (FTIR-ATR) analysis respectively. X-ray diffraction (XRD) and mechanical strength were determined as well. The effects of polyimine content, pressure and temperature were studied on CO2 permeability (P) and selectivity. The pressure changes revealed exponentially increases on CO2 permeability by plasticization, facilitated transfer and solution-diffusion mechanisms, but decreases on CH4 and N-2 permeations. Remarkable permeation (P = 3000 Barrer) of CA/PM-4 (1:3 % w/w) and ideal selectivity ratios of CO2/N-2 = 59, CO2/CH4 = 33.7 were obtained at 3 bar and 35 degrees C versus neat CA membrane.

The mechanism of a one-substrate transketolase reaction. Part II

In a recent paper, we showed the difference between the first stage of the one-substrate and the two-substrate transketolase reactions – the possibility of transfer of glycolaldehyde formed as a result of cleavage of the donor substrate from the thiazole ring of thiamine diphosphate to its aminopyrimidine ring through the tricycle formation stage, which is necessary for binding and splitting the second molecule of donor substrate [O.N. Solovjeva et al., The mechanism of a one-substrate transketolase reaction, Biosci. Rep. 40 (8) (2020) BSR20180246]. Here we show that under the action of the reducing agent a tricycle accumulates in a significant amount. Therefore, a significant decrease in the reaction rate of the one-substrate transketolase reaction compared to the two-substrate reaction is due to the stage of transferring the first glycolaldehyde molecule from the thiazole ring to the aminopyrimidine ring of thiamine diphosphate. Fragmentation of the four-carbon thiamine diphosphate derivatives showed that two glycolaldehyde molecules are bound to both coenzyme rings and the erythrulose molecule is bound to a thiazole ring. It was concluded that in the one-substrate reaction erythrulose is formed on the thiazole ring of thiamine diphosphate from two glycol aldehyde molecules linked to both thiamine diphosphate rings. The kinetic characteristics were determined for the two substrates, fructose 6 phosphate and glycolaldehyde.
