Preparation and analysis of photochromic behavior of carboxymethyl chitin derivatives containing spiropyran moieties

1MODIFIER LETTER PRIME-(2-Acryloxyethyl)-3,3MODIFIER LETTER PRIME-dimethyl-6-nitrospiro[2 H-1-benzopyran-2,2MODIFIER LETTER PRIME-indoline] (SPA) was synthesized and grafted onto a water-soluble carboxymethyl chitin (CMCH) macromolecule to prepare a photochromic copolymer (CMCH-g-SPA). The structure of CMCH-g-SPA was characterized by Fourier-transform infrared (FT-IR) spectroscopy, thermogravimetric (TG) analysis, X-ray diffraction (XRD) analysis, water-solubility evaluation, and UV-vis spectroscopy. XRD patterns of CMCH-g-SPA revealed that grafting copolymerization disrupts the CMCH semicrystalline structure, thus improving water solubility. UV-vis spectroscopy results supported the negative photochromic behavior of the merocyanine (MC) form of CMCH-g-SPA (CMCH-g-MCA) present in a water solution of the target copolymer. In addition to high solvent polarity, the intermolecular and intramolecular electrostatic attraction between the indolenine cation and the COO(-)anion were found to be influencing factors, which stabilize these MC form of spiropyran groups grafted onto CMCH. In a water solution, visible light bleaching was completed over a short period (8 minutes) under artificial visible light irradiation and the thermal coloration reaction, whose rate constant at 25 degrees C was 4.64 x 10(-4) s(-1), which fit the first-order reaction equation. After ten photochromic cycles in water solution, the relative absorption intensity of CMCH-g-MCA decreased by 7.92%.

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 56341-37-8 is helpful to your research. Formula: C8H6ClNO.

Synthesis and characterization of apHand photoresponsive copolymer of acrylamide and spiropyran

In this research, the solution properties of acrylamide and spiropyran acrylate copolymers were investigated. Spiropyran acrylate was synthesized by the reaction of 1 ‘,3 ‘,3 ‘-trimethyl-6-hydroxyspiro(2H-1-benzopyran-2,2 ‘-indoline) and acryloyl chloride. The free radical solution polymerization was used to attain a specialty responsive polymer. Characterization was carried out using nuclear magnetic resonance (NMR), Fourier-transform spectroscopy (FTIR), and ultraviolet-visible spectroscopy (UV-vis). The FTIR and NMR results showed that the copolymer synthesis was successful, and the copolymer contained spiropyran monomer. UV analyses indicated that the photoresponsive behavior of the copolymer in the protic and aprotic solvents was quite the opposite, and the polymer absorption spectrum in the basic aqueous solutions was red-shifted.

Electrochemical Total Synthesis of Pyrrolophenanthridone Alkaloids: Controlling the Anodically Initiated Electron Transfer Process

Electrochemical intramolecular C(sp(2))-H cross-coupling and dehydrogenative indole synthesis were developed. Both reactions were initiated by anodic oxidation of the same electron-rich indoline moiety, but the product selectivity was controlled by different electron-transfer processes. Intramolecular cross-coupling was achieved by the generation of a strong electrophilic radical cation intermediate in the MeNO2-HFIP-LiClO4 system. Indole formation was accomplished through benzylic oxidation and continuous deprotonation. We applied these reactions to the total synthesis of natural pyrrolophenanthridone alkaloids.

Deciphering interior polarity of lysosome in live cancer and normal cells using spectral scanning microscopy

A lysosome specific, pH tolerant, and polarity-sensitive fluorescent probe (LyPol) is designed and synthesized for the determination of lysosomal polarity in live cells. LyPol possesses an intramolecular charge transfer (ICT) properties with high quantum yield in water and in other polar solvents such as methanol, ethanol, dimethyl sulfoxide, acetonitrile, etc. The fluorescence maxima and lifetime increase linearly with a non-specific manner with an increase in the polarity of its surrounding environment. A morpholine group connected with an alkyl linker acts as a lysosome directing moiety, which is attached to the fluorescent core of LyPol. The selective localization of LyPol inside the lysosome was confirmed with live-cell confocal imaging. Further, the spectral scanning confocal technique was utilized to determine the emission spectrum of LyPol inside lysosome, and the polarity turns out to be quite lower as compared to water. Moreover, the combined spectroscopic and live-cell microscopy confirms that the interior of the lysosome is significantly non-polar in cancer cells compared to normal cells. We believe that this report on the measuring polarity inside the biological system with a solvatofluorochromic probe will be of immense interest to researchers working in the multidisciplinary area of biophysics, microscopy, chemical biology, and organelle biology.

A Subset of Purposeless Oral Movements Triggered by Dopaminergic Agonists Is Modulated by 5-HT2C Receptors in Rats: Implication of the Subthalamic Nucleus

Dopaminergic medication for Parkinson’s disease is associated with troubling dystonia and dyskinesia and, in rodents, dopaminergic agonists likewise induce a variety of orofacial motor responses, certain of which are mimicked by serotonin2C (5-HT2C) receptor agonists. However, the neural substrates underlying these communalities and their interrelationship remain unclear. In Sprague-Dawley rats, the dopaminergic agonist, apomorphine (0.03-0.3 mg/kg) and the preferential D2/3 receptor agonist quinpirole (0.2-0.5 mg/kg), induced purposeless oral movements (chewing, jaw tremor, tongue darting). The 5-HT2C receptor antagonist 5-methyl-1-[[2-[(2-methyl-3-pyridyl)oxyl]-5-pyridyl]carbamoyl]-6-trifluoromethylindone (SB 243213) (1 mg/kg) reduced the oral responses elicited by specific doses of both agonists (0.1 mg/kg apomorphine; 0.5 mg/kg quinpirole). After having confirmed that the oral bouts induced by quinpirole 0.5 mg/kg were blocked by another 5-HT2C antagonist (6-chloro-5-methyl-1-[6-(2-methylpiridin-3-yloxy)pyridine-3-yl carbamoyl] indoline (SB 242084), 1 mg/kg), we mapped the changes in neuronal activity in numerous sub-territories of the basal ganglia using c-Fos expression. We found a marked increase of c-Fos expression in the subthalamic nucleus (STN) in combining quinpirole (0.5 mg/kg) with either SB 243213 or SB 242084. In a parallel set of electrophysiological experiments, the same combination of SB 243213/quinpirole produced an irregular pattern of discharge and an increase in the firing rate of STN neurons. Finally, it was shown that upon the electrical stimulation of the anterior cingulate cortex, quinpirole (0.5 mg/kg) increased the response of substantia nigra pars reticulata neurons corresponding to activation of the hyperdirect (cortico-subthalamonigral) pathway. This effect of quinpirole was abolished by the two 5-HT2C antagonists. Collectively, these results suggest that induction of orofacial motor responses by D2/3 receptor stimulation involves 5-HT2C receptor-mediated activation of the STN by recruitment of the hyperdirect (cortico-subthalamonigral) pathway.

Palladium/Norbornene Chemistry in the Synthesis of Polycyclic Indolines with Simple Nitrogen Sources

An efficient procedure has been developed to synthesize -indoline derivatives through a palladium-catalyzed Heck reaction/C-H activation/dual amination cascade in one pot. This constitutes the first intermolecular catalytic approach to directly accessN-alkylindolines with a broad substrate scope in the absence of any ligands. This method highlights the use of readily available amines and ureas as the required nitrogen sources in building up the indoline core.
