And the article contained the following:

Parkinson’s disease (PD) is a chronic neuro-degenerative ailment characterized by impairment in various motor and nonmotor functions of the body. In the past few years, adenosine A2A receptor (A2AR) antagonists have attracted much attention due to significant relief in PD. Therefore, in the current study, we intend to disclose the development of novel 1,3,5-triazines as A2AR antagonist. The radioligand binding and selectivity of analogs were tested in HEK293 (human embryonic kidney) and the cells were transfected with pcDNA 3.1(+) containing full-length human A2AR cDNA and pcDNA 3.1(+) containing full-length human A1R cDNA, where they exhibit selective affinity for A2AR. Mol. docking anal. was also conducted to rationalize the probable mode of action, binding affinity, and orientation of the most potent mol. (7c) at the active site of A2AR. It has been shown that compound 7c form numerous nonbonded interactions in the active site of A2AR by interacting with Ala59, Ala63, Ile80, Val84 Glu169, Phe168, Met270, and Ile274. The study revealed 1,3,5-triazines as a novel class of A2AR antagonists. The experimental process involved the reaction of 4-Phenylthiazol-2-amine(cas: 2010-06-2).Recommanded Product: 4-Phenylthiazol-2-amine

On May 16, 2006, Masuda, Masami; Suzuki, Nobuyuki; Taniguchi, Sayuri; Oikawa, Takayuki; Nonaka, Takashi; Iwatsubo, Takeshi; Hisanaga, Shin-ichi; Goedert, Michel; Hasegawa, Masato published an article.COA of Formula: C14H12N2S The title of the article was Small Molecule Inhibitors of α-Synuclein Filament Assembly. And the article contained the following:

α-Synuclein is the major component of the filamentous inclusions that constitute defining characteristics of Parkinson’s disease and other α-synucleinopathies. Here we have tested 79 compounds belonging to 12 different chem. classes for their ability to inhibit the assembly of α-synuclein into filaments in vitro. Several polyphenols, phenothiazines, porphyrins, polyene macrolides, and Congo red and its derivatives, BSB and FSB, inhibited α-synuclein filament assembly with IC50 values in the low micromolar range. Many compounds that inhibited α-synuclein assembly were also found to inhibit the formation of Aβ and tau filaments. Biochem. anal. revealed the formation of soluble oligomeric α-synuclein in the presence of inhibitory compounds, suggesting that this may be the mechanism by which filament formation is inhibited. Unlike α-synuclein filaments and protofibrils, these soluble oligomeric species did not reduce the viability of SH-SY5Y cells. These findings suggest that the soluble oligomers formed in the presence of inhibitory compounds may not be toxic to nerve cells and that these compounds may therefore have therapeutic potential for α-synucleinopathies and other brain amyloidoses. The experimental process involved the reaction of 2-(4-Aminophenyl)-6-methylbenzothiazole(cas: 92-36-4).COA of Formula: C14H12N2S

Scott; Kirkwood, Alfredo; Yang, Jerry; Pak, Daniel T. S.; Lee, Hey-Kyoung; Hoe, Hyang-Sook published an article.Recommanded Product: 2-(4-Aminophenyl)-6-methylbenzothiazole The title of the article was A tetra(ethylene glycol) derivative of benzothiazole aniline enhances Ras-mediated spinogenesis. And the article contained the following:

The tetra(ethylene glycol) derivative of benzothiazole aniline, BTA-EG4, is a novel amyloid-binding small mol. that can penetrate the blood-brain barrier and protect cells from Aβ-induced toxicity. However, the effects of Aβ-targeting mols. on other cellular processes, including those that modulate synaptic plasticity, remain unknown. We report here that BTA-EG4 decreases Aβ levels, alters cell surface expression of amyloid precursor protein (APP), and improves memory in wild-type mice. Interestingly, the BTA-EG4-mediated behavioral improvement is not correlated with LTP, but with increased spinogenesis. The higher dendritic spine d. reflects an increase in the number of functional synapses as determined by increased miniature EPSC (mEPSC) frequency without changes in presynaptic parameters or postsynaptic mEPSC amplitude. Addnl., BTA-EG4 requires APP to regulate dendritic spine d. through a Ras signaling-dependent mechanism. Thus, BTA-EG4 may provide broad therapeutic benefits for improving neuronal and cognitive function, and may have implications in neurodegenerative disease therapy. The experimental process involved the reaction of 2-(4-Aminophenyl)-6-methylbenzothiazole(cas: 92-36-4).Recommanded Product: 2-(4-Aminophenyl)-6-methylbenzothiazole

On March 4, 2005, Taniguchi, Sayuri; Suzuki, Nobuyuki; Masuda, Masami; Hisanaga, Shin-ichi; Iwatsubo, Takeshi; Goedert, Michel; Hasegawa, Masato published an article.Category: thiazole The title of the article was Inhibition of Heparin-induced Tau Filament Formation by Phenothiazines, Polyphenols, and Porphyrins. And the article contained the following:

Tau protein is the major component of the intraneuronal filamentous inclusions that constitute defining neuropathol. characteristics of Alzheimer’s disease and other tauopathies. The discovery of tau gene mutations in familial forms of frontotemporal dementia has established that dysfunction of the tau protein is sufficient to cause neurodegeneration and dementia. Here we have tested 42 compounds belonging to nine different chem. classes for their ability to inhibit heparin-induced assembly of tau into filaments in vitro. Several phenothiazines (methylene blue, azure A, azure B, and quinacrine mustard), polyphenols (myricetin, epicatechin 5-gallate, gossypetin, and 2,3,4,2′,4′-pentahydroxybenzophenone), and the porphyrin ferric deuteroporphyrin IX inhibited tau filament formation with IC50 values in the low micromolar range as assessed by thioflavin S fluorescence, electron microscopy, and Sarkosyl insolubility Disassembly of tau filaments was observed in the presence of the porphyrin phthalocyanine. Compounds that inhibited tau filament assembly were also found to inhibit the formation of Aβ fibrils. Biochem. anal. revealed the formation of soluble oligomeric tau in the presence of the inhibitory compounds, suggesting that this may be the mechanism by which tau filament formation is inhibited. The compounds investigated did not affect the ability of tau to interact with microtubules. Identification of small mol. inhibitors of heparin-induced assembly of tau will form a starting point for the development of mechanism-based therapies for the tauopathies. The experimental process involved the reaction of 2-(4-Aminophenyl)-6-methylbenzothiazole(cas: 92-36-4).Category: thiazole

And the article contained the following:

A facile and more efficient solvent-free mechanochem. synthetic route has been developed for the synthesis of a series of solid state white light emissive thiazole-based donor-acceptor (D-A) type fluorophores, 2-(3-pyridyl)/2-aminothiazoles from ω-bromomethylketones and pyridine-3-carbothioamide/thiourea in the presence of silica-supported HClO4 as a reusable solid Bronsted acid catalyst at RT. The photophys. and electrochem. properties of these compounds have been derived. Most of the studied D-A type solid thiazole-based fluorophores emitted white light and it can be tuned from warm – ideal – cold white light by introduction of a variety of substituents at 4th position of 2-(3-pyridyl)/2-aminothiazoles. Further, HOMO and LUMO energy levels of the titled compounds are found to be in the range -5.52 eV to -5.72 eV and -1.84 eV to -2.45 eV, resp. The lifetimes of these levels of thiazole-based fluorophores have been determined through luminescence decay curves and are found to be in the range of 7.7-11μs. The photophys. and electrochem. properties of the synthesized thiazole-based fluorophores indicate that the compounds could be promising materials for white organic light emitting devices.

A series of novel triaryl-based sulfamic acid analogs I [R = H, 3-FC6H4CH2C(O), 4-MeOC6H4SO2, etc.; Ar = Ph, 4-phenylthiazol-2-yl, 4-(2-thienyl)thiazol-2-yl] was designed, synthesized and evaluated as inhibitors of human protein tyrosine phosphatase beta (HPTPβ). A novel, easy and efficient synthetic method was developed for target compounds I, and the activity determination results showed that most of compounds were good HPTPβ inhibitors. Interestingly, the compounds I [R = 1-tert-butoxycarbonylpiperidine-4-carbonyl, Ar = Ph; R = H, Ar = 4-(2-thienyl)thiazol-2-yl] with simple structure not only showed potent inhibitory activity on HPTPβ but also had good inhibitory selectivity over other PTPs (PTP1B, SHP2, LAR and TC-PTP). The mol. docking simulation of compounds with the protein HPTPβ helped to understand the structure-activity relationship and clarified some confusing assay results. This research provided references for further drug design of HPTPβ and other PTPs inhibitors.

And the article contained the following:

Abstract: In this research work, copolyimides (PIa,b) were synthesized by chem. routs. We used perylene-3,4,9,10-tetracarboxylic dianhydride and synthesized diamines (DAa,b) containing thiazole ring as monomers to obtain PIa,b which were characterized by 1HNMR and FTIR spectroscopies. We prepared POAP/PIa and POAP/PIb by depositing poly ortho amino phenol (POAP) as conductive polymer on the surface of PIa,b via in situ electropolymerization To evaluate the effect of the PIa,b in terms of the electrochem. performance of composites, we used galvanostatic charge/discharge, cyclic voltammetry, and electrochem. impedance spectroscopy. The specific capacitance of 207.2 and 322.4 F/g are obtained for POAP/PIa and POAP/PIb, resp. All these evidences prove that POAP/PI composites have long cycle life as well as high specific capacitance, which are indicative for being a good candidate in terms of application in supercapacitors.
