Discovery of novel isothiazole inhibitors of the TrkA kinase: Structure-activity relationship, computer modeling, optimization, and identification of highly potent antagonists

The design, synthesis, and biological evaluation of potent inhibitors of the TrkA kinase is presented. A homology model is created to aid in the enhancement of potency and selectivity of isothiazole inhibitors found during a high-throughput screen. Three different syntheses are utilized to make diverse analogs within this series. Aminoheterocycles are found to be good urea surrogates, whereas bicyclic substituents on the C3 thio group were found to be extremely potent TrkA inhibitors in kinase and cell assays.

REACTIONS OF CHELATED BETA-FUNCTIONALIZED AMINO-ACIDS WITH THIONYL CHLORIDE

A variety of bis(ethane-1,2-diamine)cobalt(III) complexes containing chelated beta-functionalized amino acids have been treated with SOCl2 in dimethylformamide. These compounds undergo beta-elimination reactions to give chelated enamines followed by either rearrangement to the related imine complexes or further reactions with SOCl2 to give chelated isothiazole-3-carboxylato complexes. Mechanisms are proposed for the reactions.

Synthesis of N,N ‘-linked bisazaheterocycles with sulfonamide structure via oxidation of S,N-heteroaromatic cations

N-Phthalimidyl- and N-quinazolinyl-substituted 3-hydroperoxy-, 3-hydroxy- and 3-oxoisothiazole 1,1-dioxides have been synthesized by the sequence of oxidation reactions from N,N’-linked isothiazolium perchlorates with hydrogen peroxide, MMPP, and pyridinium dichromate. Isothiazolium salts without acceptor substituents did not give N-substituted sultams. Novel N,N’-bisazaheterocycles were investigated as inhibitors of acetylcholinesterase (AChE) and human leukocyte elastase (HLE). Two 2,3-dihydro-3-hydroperoxy-2-(phthalimid-1-yl)isothiazole 1,1-dioxides were found to inhibit AChE.

Effects of molecular structure on dyeing performance and colour fastness of yellow dyestuffs applied to polypropylene fibres in supercritical carbon dioxide

Thirteen dyestuffs of four chemical classes (quinophthalone, anthraquinone, isothiazole-fused anthrone and pyridone azo) were applied for the dyeing of unmodified polypropylene fibres in supercritical carbon dioxide. From these 13 dyestuffs, three dyestuffs that have a pure yellow hue and good dyeability for polypropylene fibres were found. The results of a dyeability test using the 13 dyestuffs suggested that the affinity for polypropylene fibres requires, in the structural character of the dyestuff molecule, not only extreme hydrophobicity but also high aliphaticity. The isothiazole-fused anthrone nonanamide dyestuff and two types of N-butyl substituted pyridone azo dyestuffs were examined for build-up and colour fastness properties. The light fastness of the dyed fabric was not so good. The ratings of fastness to washing, perspiration and rubbing ranged from excellent to fairly good with the increase of the depth of shade. From the relationship between the build-up curve and the colour fastness, it was found that the dyestuff of the isothiazole-fused anthrone nonanamide is suitable for polypropylene dyeing in a pale or medium shade, and that the two types of N-butyl substituted pyridone azo dyestuffs are suitable in a deep shade.

Aza-substituted thiophene derivatives: Structures, dipole moments, and polarizabilities

Ab initio calculations of dipole moments and static dipole polarizabilities are reported for nine heteroaromatic five-membered rings-thiophene, thiazole, isothiazole, the four thiadiazoles, and the two thiatriazoles-all at their MP2/6-31G** geometries. Extensive basis sets have been used, and the approximate applicability of the variational principle to the Hartree-Fock polarizability has been discussed. Electron correlation effects have been investigated up to the MP4(SDQ) level for a representative subset of the series of the molecules considered. Our best polarizability determinations are expected to be accurate within a few percent.

Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics, 91-40-7, Name is 2-(Phenylamino)benzoic acid, SMILES is O=C(O)C1=CC=CC=C1NC2=CC=CC=C2, belongs to isothiazole compound.

Reaction of trithiazyl trichloride with active methylene compounds

Activated allylic compounds react with trithiazyl trichloride, (NSCl),, to give 1,2,5-thiadiazoles 1 and isothiazoles 2. An allylic 2-substituent normally prevents formation of an aromatic 1,2,5-thiadiazole, and isothiazole formation becomes the major pathway. Simple allylic compounds are not very reactive towards (NSCl)(3) but a terminal electron withdrawing group (CO2Et) enhances the reactivity. With unsymmetrical allylic compounds, isothiazole formation is regiospecific placing the more electron withdrawing group adjacent to the ring sulfur. 1,3-Diketones give 3-acyl-1,2,5-thiadiazoles; unsymmetrical 1,3-diketones give these thiadiazoles regiospecifically, explicable by cyclisation of an intermediate onto the more reactive carbonyl group. 1,4-Diketones give 3,4-diacyl-1,2,5-thiadiazoles; thus 1,2-dibenzoyl-ethane, -ethene and -ethyne all give 3,4-dibenzoylthiadiazole (40-44%). Many of these trithiazyl trichloride reactions provide attractive one-step routes to 1,2,5-thiadiazoles and isothiazoles.

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 91-40-7 is helpful to your research. HPLC of Formula: C13H11NO2.

Introduction of sulfur atoms into trifluoromethylated alkenyl sulfones and chlorides using a reactive sulfur-graphite electrode

The introduction of sulfur atoms into trifluoromethylated alkenyl sulfones and chlorides were studied using a reactive sulfur-graphite electrode in N,N-dimethylformamide. A substrate, 2-(4-biphenylyl)-4,4,4-trifluoro-3-phenylsulfonyl-2-butenenitrile (1a) afforded a coupling compound bridged with a nitrogen atom of isothiazole and 1,2-dithiolane skeleton (2). 1-(4-Biphenylyl)-3,3,3-trifluoro-2-phenylsulfonylpropene (1b) without a cyano group gave a complex oligomeric compound (3) without the elimination of the phenylsulfonyl group. 2- (4-Biphenylyl)-3-chloro-4,4,4-trifluoro-2 butenenitrile (1c) having a chloro group as a leaving group gave 2,4-di (4-biphenylyl)-2,4-dicyano-1,5-bis (trifluoromethyl)-3,6-dithiabicyclo[3.1.0]hexane (4) and 2-(4-biphenylyl)-4,4,4-trifluoro-2-butenenitrile (5). Methyl 2-(4- biphenylyl)-3-chloro-4,4,4-trifluoro-2-butenoate (1d) having an ester group in the place of a cyano group afforded di-[2-(4 biphenylyl)-2-methoxycarbonyl-1 trifluoromethylethyl] disulfide (6). The formation of such sulfur-containing organofluorine compounds except for the oligomeric compound 3 is characterized as the addition of polysulfide anion(s) produced by electroreduction of elemental sulfur. followed by the elimination of the phenylsulfonyl or the chloro group.

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 61990-51-0. Category: isothiazole.
