Breslow Intermediates from a Thiazolin-2-ylidene and Fluorinated Aldehydes: XRD and Solution-Phase NMR Spectroscopic Characterization

The first generation and X-ray diffraction (XRD) analysis of a crystalline Breslow intermediate (BI) derived from a thiazolin-2-ylidene, that is, the aromatic heterocycle present in vitamin B-1, is reported. Key to success was the combined use of pentafluorobenzaldehyde and a thiazolin-2-ylidene carrying an enol-stabilizing dispersion energy donor as N-substituent. A so-called primary intermediate (PI) could be isolated in protonated form (pPI) as well and analyzed by XRD. Furthermore, the first stable BI derived from an aromatic thiazolin-2-ylidene and an aliphatic aldehyde (trifluoroacetaldehyde) was prepared and characterized by NMR spectroscopy in solution. When switching to a saturated thiazolidin-2-ylidene, reaction with pentafluorobenzaldehyde afforded a new BI in solution (NMR spectroscopy). Attempts to crystallize the latter BI resulted in the isolation of a novel thiazolidin-2-ylidene dimer that had undergone rearrangement to a hexahydro[1,4]-thiazino[3,2-b]-1,4-thiazine.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 5326-23-8. HPLC of Formula: https://www.ambeed.com/products/5326-23-8.html.

SYNTHESIS AND ANTIMICROBIAL ACTIVITY OF NOVEL OXAZOLIDINONES HAVING BENZO THIAZINE DERIVATIVES

In order to develop relatively small molecules as pharmacologically active molecules, a series of novel oxazolidinones having benzothiazine and their derivatives were synthesized and characterized by IR, H-1 NMR and Mass spectral studies. Various substituted oxazolidinone benzothiazines were prepared by simple refluxing in the presence of acetonitrile. Treatment of these oxazolidinone benzothiazine derivatives with methanesulfonyl chloride gives its sulphonate derivatives which on further treatment with sodium azide and triphenyl phosphine in acetic anhydride gave acetamide derivatives. Further the synthesized compounds were evaluated for antibacterial activity against Bacillus subtilis, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa and antifungal activity against Candida albicans and Aspergillus niger.

Inhibition of the Photobleaching of Methylene Blue by Association with Urea

Methylene Blue has a long history as a photochemical reagent and is known to undergo photofading on exposure to visible light in aqueous solution. Under aerobic conditions, photobleaching occurs by way of a two-step process involving intermediary formation of singlet oxygen. The first step is ascribed to regio-selective addition of singlet oxygen within the precursor complex. This geminate reaction ultimately leads to formation of the leuco-dye via a slower second step. Urea forms a weak ground-state complex with Methylene Blue which affects the optical properties of the dye but is not evident by NMR spectroscopy. This complex is weakly fluorescent and undergoes intersystem crossing to the triplet manifold. The presence of urea decreases the rate of photobleaching of the dye and, at high concentrations of urea, the bleaching kinetics are consistent with an equilibrium mixture of complexed and free dye. The complexed dye does not bleach on the timescale of the experiment. Such protection might arise from urea blocking access to the site where geminate addition of O-2 takes place.

Synthesis and characterisation of some novel fused thiazolo[3,2-a] pyrimidinones and pyrimido[2,1-b][1,3]thiazinones

Reactions of 7,9-bis(4-methoxyphenyl)-2-thioxo-2,3-dihydropyrido[3′,2′:4,5]thieno[3,2-d]pyrimidin-4(1H)-one with alpha-haloketones, chloroacetonitrile and DMAD, afforded the corresponding fused thiazolo[3,2-a]pyrimidinone derivatives. The reaction of the thione with chloroacetic acid and an appropriate aromatic aldehyde yielded the respective 2-arylidene-2H-pyrido[3′,2′:4,5]thieno[3,2-d]thiazolo[3,2-a]pyrimidine-3,5-diones. Also, the treatment of thione with arylidenemalononitriles gave the fused pyrimido[2,1-b][1,3]thiazine derivatives, respectively. The structures of the synthesised products were confirmed by IR, H-1 NMR and mass spectral techniques.

Prolongation of skin graft survival in mice by an azaphenothiazine derivative

Azaphenothiazines are predominantly immunosuppressive compounds. We evaluated the efficacy of an azaphenothiazine derivative, 6-chloroetlaylureidoethyldiquino[3,2-b;2′,3′-e][1,4]thiazine (DQT) in prolongation of survival of skin allografts between BALB/c and C5781/6 mice. The mice were treated intraperitoneally (i.p.) with 100 mu g of DQT on alternate days, on days 1-13 of the experiment (7 doses). The effect of DQT on a two-way mixed lymphocyte reaction (MLR) in the human model, as well as its effect on production of TNF alpha and IL-10 in a whole blood cell culture, stimulated by lipopolysaccharide (LPS), were evaluated. In addition, DQT effects were investigated regarding the proportion of T cell subsets in human peripheral blood lymphocytes (PBMC) by flow cytometry. Lastly, the effect of DQT on expression of signaling molecules involved in pro apoptotic pathways was determined by RT PCR. The results showed that DQT significantly extended skin graft survival. The compound also strongly suppressed two-way MLR in the human model at a concentration range of 2.5-5.0 mu M. In addition, DQT inhibited LPS-inducible TNF alpha, but not IL-10 production. The compound preferentially caused a loss of the CD3-CD8 +CD11b + PBMC cell subset, and transformed CD3 + CD8 +(high) into CD3 + CD8+(low) cells. Lastly, we demonstrated significant increases in expression of caspases (in particular caspase 8) and of p53 in a culture of Jurkat T cells. We conclude that the immunosuppressive actions of the compound in allograft rejection may be predominantly associated with induction of cell apoptosis and inhibition of TNF a production. The apoptosis could be predominantly selective for the CD3-CD8 + CD11b + cell phenotype.

Hydrazide-integrated carbazoles: synthesis, computational, anticancer and molecular docking studies

A new class of carbazole-based hydrazides 6a-c, synthesized from carbazole by employing a multistep synthetic strategy, has been described. Detailed insight into their structures (6a-c) has been elucidated by UV-Vis, FT-IR and NMR (H-1 and C-13) spectroscopic studies. Theoretical investigation of the molecules 6a-c has been accomplished utilizing DFT and TD-DFT techniques with the B3LYP/6-311++G(d,p) method. Theoretical findings such as optimized structural, vibrational, and electronic properties, and proton and carbon chemical shifts of the targets 6a-c are in harmony with their experimental results and/or structurally related reported ones. Cytotoxicity of the target hydrazides 6a-c has been evaluated using human pancreatic cancer cells (AsPC1 and SW1990). The hydrazides 6a-c displayed a significant in vitro cytotoxic effect against both the pancreatic cancer cells AsPC1 (concentration that inhibits 50% cell viability, IC50: 3.42 +/- 0.41 mu M for 6a) and SW1990 (IC50: 22.42 +/- 1.40 mu M for 6a). The superior binding energy resulting from the in silico molecular docking approach of the hydrazide 6a indicates its greater affinity towards the receptor (binding energy: -8.63 kcal mol(-1) and IC50: 475.05 nM). Thus, the hydrazide 6a could serve as a new lead for the development of anticancer agents.

Magnetic Nanoparticles Impregnated, Cross-Linked, Porous Chitosan Microspheres for Efficient Adsorption of Methylene Blue from Pharmaceutical Waste Water

The study demonstrates the preparation of MnFe2O4 impregnated chitosan-microspheres (CMMS) as adsorbents for efficient removal of cationic thiazine dye, methylene blue. A facile approach with great economic and technical advantages to obtain highly crystalline manganese ferrite nanoparticles by solution combustion method is accounted. CMMS were characterized and evaluated for MB adsorption using linear forms of Freundlich and Langmuir adsorption isotherms, pseudo-first order, pseudo-second order and Elovich kinetic models. Application of CMMS to pharmaceutical waste, desorption of MB and reusability of CMMS are reported. Significantly, MB concentration in treated real sample was reduced by similar to 18 times to that of initial concentration.
