Kinetics of palladium nano-particles catalyzed reduction of Methylene Green by hydrazine: Role of induction period in determining mechanistic pathway

Methylene Green (MG), a thiazine dye, is catalytically reduced by N2H4 in presence of palladium nanoparticles (Pdn) in buffer media. The observed rate, k(o) increases with increase in [Pdn], [N2H4] and pH but decrease with increase in ionic strength (maintained with NaNO3). Unlike other thiazine dyes, the catalyzed reduction of MG shows an induction period which is caused by the restructuring of Pdn surface. The rate of adsorbate-induced surface restructuring which increase with increase in [N2H4] but independent of [MG], suggest that only N2H4 is adsorbed on Pdn surface during the catalyzed reaction. Interestingly, NO3 ions are also adsorbed on the Pdn surface and turn the surface negatively charged. The reductant, N2H4 is adsorbed on this negatively charged Pdn surface before it reacts with MG. The surface restructuring energy of Pdn, though is constant (78.8 +/- 1.6 kJ M-1) over the temperature range of 288-313 K but the activation energy for the catalyzed reduction varies with temperatures. The convex Arrhenius plot illustrates that activation energy is different in lower (288-304 K, 123.8 +/- 12.6 kJ M-1) and higher temperature range (304-313 K, 69.2 +/- 2.1 kJ M-1) and around the inversion temperature, Tinv (304 K) a change in the nature of transition state takes place.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 66-27-3, in my other articles. Category: thiazines.

Eco-Friendly Acaricidal Effects of Nylon 66 Nanofibers via Grafted Clove Bud Oil-Loaded Capsules on House Dust Mites

Acaricidal nylon 66 fabrics (AN66Fs) grafted with clove oil-loaded microcapsules (COMCs) were developed against Dermatophagoides farina (D. gallinae). The average diameter was about 2.9 mu m with a range of 100 nm-8.5 mu m. COMCs carried clove oil loading of about 65 vol %. COMCs were chemically grafted to electrospun nylon nanofibers by the chemical reactions between -OH groups of COMCs and -COOH end groups of nylon fabrics to form ester linkages. AN66Fs had an effect on D. farinae depending on COMCs loadings. The increase in COMCs loading of AN66Fs from 5 to 15 wt % increased from 22% to 93% mortality against D. farinae within 72 h. However, AN66Fs containing over 20 wt % COMCs were more effective, showing up to 100% mortality within 24 h because the large amount of monoterpene alcohol, eugenol. This research suggests the use of clove oil and its major constituent eugenol as eco-friendly bioactive agents that can serve as a replacement for synthetic acaricides in controlling the population of D. farinae.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 147118-35-2 is helpful to your research. Category: thiazines.

The role of S-bond in tenoxicam keto-enolic tautomerization

A non-steroidal anti-inflammatory drug, 4-hydroxy-2-methyl-N-2-pyridyl-2H-thieno.2,3-e)-1,2-thiazine-3-carboxamide 1,1-dioxide, called tenoxicam (TXM), with important implications in cancer treatment, has a peculiarity with respect to other molecules from the oxicam family. TXM is predominantly found in the zwitterionic form (ZWC) within the crystal structures of pure compounds and their solvates; however, it can be present in the beta-keto-enolic form (BKE) or beta-diketone (BDK) form. To understand this phenomenon, the combined effects of environment (solvent) and intra-molecular non-covalent interactions on the TXM keto-enol tautomerization were investigated through a combined experimental and computational study. We found that the polarity of a solvent had a minor influence on the crystallization process; this allowed to us synthesize and solve six new solvates with TXM in the ZWC form. Careful investigation of the non-covalent interactions between the sulphur atom of thiophenyl moiety and oxygen of the carbonyl group (S-bond) through a computational approach with the natural bond orbital (NBO) theory has shown that TXM crystallization is modulated by the S-bond. This study further confirms the importance of the S-bond in the drug design; however, nowadays, it is still underestimated.

Synthesis, biological activity, distribution and membrane permeability of novel spiro-thiazines as potent neuroprotectors

New spiro-derivatives of 1,3-thiazine-potential neuroprotectors have been synthesized. It has been determined that the obtained compounds are biologically active and capable of blocking the glutamate-induced calcium ion uptake into synaptosomes of rat brain cortex. The inhibitory activity of the test substances was shown to depend on the chemical nature and structure of the substituents bound with an exocyclic nitrogen atom. Non-polar alkyl and polar radicals with halogen, oxygen and nitrogen atoms were used as substituents. It is typical of the active spiro-thiazines to have alkyl substituents in ortho-and para-position of the benzene ring. Among the investigated spiro-thiazines it is the derivatives with ethyl- and isopropyl-groups in the aril part of the molecules that are the lead-compounds with a high inhibitory ability. We measured the distribution coefficients of the substances in octanol/buffer and hexane/buffer systems and made conclusions about the ability of the investigated drug-like compounds to penetrate the biological membranes. By using the parabolic model we derived a quadratic equation that allowed us to evaluate quantitatively the inhibitory activity of spiro-thiazines with hydrophobic substituents based on lipophilicity data. We also studied the permeability through the phospholipidic membrane and introduced a correlation equation describing the dependence of the investigated spiro-thiazines activity on the descriptors characterizing the donor acceptor properties.

Organic-inorganic hybrid layer-by-layer electrostatic self-assembled film of cationic dye Methylene Blue and a clay mineral: Spectroscopic and Atomic Force microscopic investigations

The metachromic cationic dye Methylene Blue (MB) belongs to the thiazine class of organic dye. This dye cation can interact electrostatically with inorganic clay mineral Montmorillonite (MMT) to form organic inorganic hybrid layer-by-layer (LbL) self-assembled film onto a poly(allylamine hydrochloride) coated quartz substrate. The degree of dye aggregations in LbL films was found to depend on concentrations of both MMT clay and MB in LbL self-assembled films as evidenced by UV vis absorption spectroscopic technique. The adsorption of dye molecules to the LbL films was found to a two-step exponential process: first step was very fast and the later process had a much delay period. Also the assembling behavior and organizations of MB molecules in the host clay matrix in LbL films significantly depend on pH of dye solution from which LbL film was fabricated. For MMT/MB mixed solution the pi-pi transition of absorption bands of MB shifted to lower wavelength due to the formation of large number of H-aggregates in their mixed aqueous solution. Fourier Transform infrared (in ATR mode) spectroscopic method was employed to explore the electrostatic interaction between clay MMT and MB in LbL films. Atomic Force microscopic image of hybrid LbL films revealed the surface morphology and roughness profile of the organic-inorganic hybrid molecular assemblies onto the solid substrate.
