ANTICONVULSANT EVALUATION OF SOME NOVEL 1, 3-THIAZINE DERIVATIVES

In the present study, a series of novel biologically active 8-benzylidene-6-tert-butyl-4-phenyl-5, 6, 7, 8-tetrahydro-benzo-1, 3-thiazin – 2 -imines (TB1-TB12) were synthesized and evaluated for their biological activities. Initially, 2,6-dibenzylidene-4-tert-butylcyclohexanones were synthesized by Claisen-Schmidt condensation of 4-tert-butylcyclohexanone with various aromatic aldehydes in the presence of dilute sodium hydroxide. Further these compounds were subjected to cyclocondensation with thiourea, in isopropyl alcohol, catalyzed by aqueous potassium hydroxide to form 4-aryl-8-arylidene-5,6,7,8-tetrahydro-1H-benzo[d][1,3] thiazin-2(4H)-imines (TB1-TB12). The structures of the newly synthesized compounds have been established on the basis of their spectral data and elemental analysis. Anticonvulsant activity was performed by Maximal electroshocks (MES) method by using Diazepam as standard reference. These compounds were subjected to molecular properties prediction, drug-likeness, lipophilicity and solubility parameters determination using Molinspiration, Osiris program was used for prediction of the toxicity, and also Molsoft and ALOGPS 2.1 softwares. Among all compounds TB5 and TB8 containing lipophilic methoxyl and isopropyl group were more potent whereas TB12 containing hydroxyl groups were least potent among the series.

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 66-27-3 is helpful to your research. Quality Control of Methyl methanesulfonate.

Stereoselective Polymer-Supported Synthesis of Morpholine- and Thiomorpholine-3-carboxylic Acid Derivatives

Herein we report the polymer-supported synthesis of 3,4-dihydro-2H-1,4-oxazine-3-carboxylic acid derivatives using immobilized Fmoc-Ser(tBu)-OH and Fmoc-Thr(tBu)-OH as the starting materials. After the solid-phase-synthesis of N-alkyl-N-sulfonyl/acyl intermediates, the target dihydrooxazines were obtained using trifluoroacetic acid-mediated cleavage from the resin. This approach was also studied for the preparation of dihydrothiazines from immobilized Fmoc-Cys(Trt)-OH. Inclusion of triethylsilane in the cleavage cocktail resulted in the stereoselective formation of the corresponding morpholine/thiomorpholine-3-carboxylic acids. Stereochemical studies revealed the specific configuration of the newly formed stereocenter and also the formation of stable N-acylmorpholine rotamers.

Nonlinear absorption of some thiazine, xanthene, and carbocyanine dyes

The saturated and two-photon absorption of various classes of heterocyclic dyes [thiazine (thionine), xanthene (erythrosine), and carbocyanine (3,3′-di-(gamma-sulfopropy1)-4,4′,5,5′-dibenzo-9-ethylthiacarbocyaninebetaine pyridinium salt, DEC)] possessing optical absorption in the 500-680 nm range were measured at the wavelengths of 1064 and 532 nm using nanosecond (10 ns) and picosecond (40 ps) pulses and z-scan technique. It was shown that reverse saturated absorption unlikely plays important role in those dyes. We defined the two-photon absorption coefficients of thionine and erythrosine at 1064nm using 40 ps pulses (0.8 x 10(-11) and 1.0 x 10(-11) cmW(-1) respectively). The concurrence of saturated absorption and two-photon absorption was analyzed in the case of thionine and erythrosine using various models. It was suggested that dimerization of those dyes significantly suppresses the nonlinear optical response in the case of both 10 ns and 40 ps pulses of 532 nm radiation. At the same time it was found that, in the case of 532 nm pulses, the monomers of thionine participate in the processes of saturated absorption and two-photon absorption, while J-aggregates of DEC show predominantly two-photon absorption.

Enhancement of nonlinear optical response of methylene blue and azure a during association with colloidal CdS quantum dots

The nonlinear optical response of thiazine dyes during association with colloidal CdS quantum dots (QDs) applying the z-scan technique at wavelength of 532 nm with use 10 ns pulses of Nd:YAG laser second harmonic were studied. Increasing in nonlinear absorption intensity in hybrid associates in comparison with the initial components were found. Moreover, UV-vis absorption spectrum shows the effective formation of dyes H-aggregates during association with colloidal QDs. Two-photon mechanism of observed nonlinear absorption in hybrid associates is proposed, based on a sharper dependence of the normalized transmittance on the incident intensity (distance between the sample and focal plane of focusing lens). And for pure solutions, the reverse saturated absorption is preferred nonlinear absorption mechanism. The nonlinear absorption coefficients for MB and AzA in the hybrid associates were found. They are beta approximate to 8.4 x 10(-9) cm W-1 (sic) approximate to 1.34 x 10(-8) cm W-1, respectively. It was shown that it is possible to control the parameters of nonlinear absorption of thiazine dyes via the hybrid association.

Methylene blue induces an analgesic effect by significantly decreasing neural firing rates and improves pain behaviors in rats

Methylene blue (MB) is a blue cationic thiazine dye and currently used in different medical settings. Notably, there have been several attempts to introduce MB for attenuating pain in the last decade. Some clinical studies reported remarkable results, which, however, have been much debated. In addition, accumulating evidence have revealed that MB diminishes voltage-gated sodium channel currents. Accordingly, in the present study, we conducted in vivo experiments, including in vivo single nerve recording and behavioral test, to investigate whether MB dampens neural firing rates and ultimately contributes to pain relief. As a result, neural firing rates significantly decreased and finally converged to zero after MB administration. This event lasted longer than that of lidocaine and was dose-dependently modulated. Furthermore, there was a marked improvement in pain behaviors. The withdrawal threshold and latency of hind paws significantly rose post-MB administration. Therefore, these results demonstrate that MB lessens pain by significantly weakening neural excitability, which implies a strong possibility that this dye may be developed as a pain-relieving medication in the future. This is the first in vivo study to elucidate the effect of MB on nerves and pain relief. (C) 2021 Elsevier Inc. All rights reserved.

Thiazine Red(+) platelet inclusions in Cerebral Blood Vessels are first signs in an Alzheimer’s Disease mouse model

Strong evidence shows an association between cerebral vascular diseases and Alzheimer’s disease (AD). In order to study the interaction of beta-amyloid (A beta) plaques with brain vessels, we crossbred an AD mouse model (overexpressing amyloid precursor protein with the Swedish-Dutch-Iowa mutations, APP_SweDI) with mice expressing green fluorescent protein (GFP) under the flt-1/VEGFR1 promoter in vessels (GFP_FLT1). Our data show, that only very few A beta plaques were seen in 4-months old mice, focused in the mammillary body and in the lateral septal nucleus. The number of plaques markedly increased with age being most prominent in 12-months old mice. Thiazine Red was used to verify the plaques. Several Thiazine Red(+) inclusions were found in GFP(+) vessels, but only in non-perfused 4-months old mice. These inclusions were verified by Resorufin stainings possibly representing cerebral amyloid angiopathy. The inclusions were also seen in non-crossbred APP_SweDI but not in wildtype and GFP_FLT1 mice. In order to characterize these inclusions Flow Cytometry (FACS) analysis demonstrated that platelets were specifically stained by Thiazine Red(+), more pronounced when aggregated. In conclusion, our data show that Thiazine Red(+) inclusions representing aggregated platelets are a first pathological sign in AD before plaque development and may become important therapeutic targets in early AD.
