Design, Synthesis, Safener Activity, and Molecular Docking of Novel N-Substituted Thiazide/Thiazole Derivatives

A series of novel substituted thiazide/thiazole compounds were designed by splicing active groups and bioisosterism. The title compounds were synthesized via the cyclization, acylation, and carbamylation. All the compounds were characterized by IR, 1H-NMR, 13C-NMR, and HRMS. The single crystal of compound 3f was determined by X-ray crystallography. The biological activity tests indicated that all the compounds showed potential safener activity to the herbicide chlorsulfuron, in which compound 3e showed almost the same level as the commercialized safener AD-67. The molecular docking results were in good agreement with the bioassay results, which demonstrated that compound 3e might compete with chlorsulfuron in the acetolactate synthase active site, causing the herbicide ineffective in maize.

Mass Spectral Fragmentation Patterns of Heterocycles. VII. Reinvestigation of Fundamental Processes in Phenothiazines

Electron impact induced fragmentation patterns of simple phenothiazines have been reinvestigated using metastable ion studies, exact mass measuremants and deuterated derivatives.Secondary fragmentation processes involving ions m/e 198, 171, 167, 166, 154, 140 and 139 have been clarified.Mechanisms for the release of sulfur (SH. and CSH.) nitrogen (HCN and H2CN.) containing fragments from phenothiazine molecular ion are proposed based on the deuterium content of the daughter ions obtained from 1,9-dideuteriophenothiazine.A revised mechanism for the expulsion of ketene from 10-acetylphenothiazine is suggested based on the fragmentation pattern of the 1,9-dideuterioderivative.The composition of m/e 140 was determined by high resolution measurement to be C10H6N and not C11H7 as previously reported.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! Read on for other articles about Reference of 2682-49-7!, Quality Control of 1-Chloro-10H-phenothiazine

Studies on Diamagnetic Susceptibility of Biologically Active Heterocycles. 1. Diamagnetic Susceptibility of Phenothiazines

Diamagnetic susceptibilities for a number of phenothiazines are reported.A theoretical method to estimate the diamagnetic susceptibility of these biologically active heterocycles is presented.Phenothiazines have been considered to be composed of two units: one consisting of a benzene nucleus containing amino and thio groups at ortho positions to the substituents and the other consisting of a benzene ring with substituents.The diamagnetic contributions of these two units have been obtained from the diamagnetic susceptibilities of substituted o-aminobenzenethiols and benzenes and have been used in estimating the diamagnetic susceptibilities of phenothiazines.It has provided excellent theoretical results.Such an excellent agreement between measured and estimated values is due to the fact that the interactions between substituents which affect the diamagnetism have been duly accounted for in such calculations.

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.Product Details of 1910-85-6, you can also check out more blogs aboutProduct Details of 1910-85-6

Half-Chair Conformations of Unsaturated Heterocyclic Compounds

The vicinal proton coupling constants were obtained for some 6-membered ring unsaturated heterocyclic compounds.The R values and ring dihedral angles were determined and found to be consistent with half-chair conformations.Relative to saturated heterocyclic compounds, the effect of the sulfur atom on ring puckering was attenuated.However, an increase in ring puckering resulted from the sulfone group and was attributed to torsional energy.

Quinolonecarboxylic Acids. 2. Synthesis and Antibacterial Evaluation of 7-Oxo-2,3-dihydro-7H-pyrido<1,2,3-de><1,4>benzothiazine-6-carboxylic Acids

A series of pyridobenzothiazine acid derivatives was synthesized and their in vitro antibacterial activity was evaluated.The 1,4-benzothiazine intermediates, which by Gould-Jacobs quinoline synthesis produced pyridobenzothiazine acids, were prepared by hydrolytic basic cleavage of substituted 2-aminobenzothiazoles and successive cyclocondensation with 1-bromo-2-chloroethane or alternatively with monochloroacetic acid, hence reduction by LiAlH4.The pyridobenzothiazine acids 10c, 30, and 31 show potent antibacterial activities against Gram-positive and Gram-negative pathogens.Structure-activity relationships are discussed.The compound 9-fluoro-10-(4-methyl-1-piperazinyl)-7-oxo-2,3-dihydro-7H-pyrido<1,2,3-de><1,4>benzothiazine-6-carboxylic acid (31) (MF-934) has been found to possess, together with the antibacterial activity, a weak acute toxicity and interesting pharmacokinetic characteristics in several animal species (rat, dog, monkey, man).

1,2-Didehydrophenothiazines: Preparation of 1-Alkyl and 1-Aryl-substituted Phenothiazines by Lithium-directed Alkylation

A general route to 1-alkyl substituted phenothiazines is described.Reactions of 2-chlorophenothiazine with an excess of methyl-, n-butyl-, s-butyl-, t-butyl- or phenyl-lithiums give the corresponding 1-substituted phenothiazines via 10-lithio-1,2-dehydrophenothiazine.Attempts to trap the presumed 1,10-dilithio intermediate failed.The reaction of 1-chlorophenothiazine with s-butyl-lithium results in preferential metallation of the 9-position. 2-Chlorophenothiazine reacts with nitrogen nucleophiles (lithium dialkylamides) to give 2-substituted products.

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about Computed Properties of C12H8ClNS

Sodium Triethylborohydride-Catalyzed Controlled Reduction of Unactivated Amides to Secondary or Tertiary Amines

The first transition-metal-free catalytic protocol for controlled reduction of amide functions using cheap and bench-stable hydrosilanes as reducing agents has been established. By altering the hydrosilane and solvent, the new method enables the selective cleavage of unactivated C-O bonds in amides and allows the C-N bonds to selectively break via the deacylated cleavage. Overall, this novel process may offer a versatile alternative to current methodologies employing stoichiometric metal systems for the controlled reduction of carboxamides.
