A review on synthesis of benzothiazine analogues

Scientific advances mainly involves the development of new and highly reactive compounds. Nitrogen and sulphur containing benzothiazines forms highly active heterocyclic agents. Benzothiazines are prominent class of heterocyclic compound. Many studies have been done in the development of benzothiazine analogues. Microwave assisted synthesis, regioselective techniques and other methods are also used for benzothiazine synthesis. Various methods have been developed for the synthesis of benzothiazine derivatives. Benzothiazines exhibits numerous therapeutic activities like anti-HIV, calcium antagonistic, anti-serotinin, analgesic, anti-mycobacterial anti-microbial, anti-oxidant, anti-rheumatic, anti-inflammatory, anti-hypertensive ,calcium channel blocker, anti-malarial, potassium channel opener, cardiovascular, anthelmintic, neuroprotective, aldose reductase inhibitor, herbicidal, pesticidal etc. This has raised the necessity to explore novel benzothiazine derivatives which can significantly contribute to the development of therapeutically active agents. And the newer development of novel benzothiazines derivatives also involves the same characteristic features and also contribute various activities.

Antimicrobial photodynamic therapy for the treatment of teeth with apical periodontitis: A histopathological evaluation

Introduction: This study evaluated the in vivo response of apical and periapical tissues of dogs’ teeth with apical periodontitis after one-session endodontic treatment with and without antimicrobial photodynamic therapy (aPDT). Methods: Sixty root canals with experimentally induced apical periodontitis were instrumented and assigned to 4 groups receiving aPDT and root canal filling (RCF) or not: group aPDT+/RCF+ (n = 20): aPDT (photosensitizer phenothiazine chloride at 10 mg/mL for 3 minutes and diode laser [lambda = 660 nm, 60 mW/cm2] for 1 minute) and RCF in the same session; group aPDT+/RCF- (n = 10); group aPDT-/RCF+ (n = 20), and group aPDT-/RCF- (n = 10). Teeth were restored, and the animals were killed after 90 days. Sections from the maxillas and mandibles were stained with hematoxylin-eosin and Mallory trichrome and examined under light microscopy. Descriptive (ie, newly formed apical mineralized tissue, periapical inflammatory infiltrate, apical periodontal ligament thickness, and mineralized tissue resorption) and quantitative (ie, periapical lesion size and number of inflammatory cells) microscopic analysis was performed. Quantitative data were analyzed by the Kruskal-Wallis and Dunn tests (alpha =.05). Results: In the aPDT-treated groups, the periapical region was moderately/severely enlarged with no inflammatory cells, moderate neoangiogenesis and fibrogenesis, and the smallest periapical lesions. Conclusions: Although apical closure by mineralized tissue deposition was not achieved, the absence of inflammatory cells, moderate neoangiogenesis, and fibrogenesis in the periapical region in the groups treated with aPDT indicate that this can be a promising adjunct therapy to cleaning and shaping procedures in teeth with apical periodontitis undergoing one-session endodontic treatment.

Enantioselective synthesis of brinzolamide (AL-4862), a new topical carbonic anhydrase inhibitor. The “DCAT Route” to thiophenesulfonamides

A large scale synthesis of the topical carbonic anhydrase inhibitors AL-4623A (13a-HCl) and AL-4862 (13b) from 3-acetyl-2,5-dichlorothiophene (“DCAT”, 1) is described. Reaction of 1 with NaSBn gave thioether 2, which was converted via sulfenyl chloride 3 and sulfenamide 5 to sulfonamide 6. Bromination of 6 gave bromo ketone 7, which upon reduction with (+)-B-chlorodiisopinocampheylborane and cyclization of the resulting bromohydrin produced S thieno[3,2-e]-1,2-thiazine 8a (96% ee) after chromatography. Treatment of 8a in THF with -BuLi at -70 C resulted in Li-Cl exchange. Reaction of the thienyllithium with SO2 and hydroxylamine O-sulfonic acid afforded bis-sulfonamide 11a. Protection of lia as the acetimidate 12a, followed by tosylation and animation, gave R amine 13a. The synthesis of 13b proceeded via primary sulfonamide 16, which was brominated, reduced, and cyclized to give S thieno[3,2-e]-1,2-thiazine 18 (>98% ee). By virtue of the ionizable NH, 18 was separable from reduction byproducts by base extraction. Alkylation of 18 with 3-bromopropyl methyl ether afforded 8b, which was converted as above, via lib, to AL-4862 (13b). These procedures provided multihundred gram lots of 13a and 13b.

Why Have Clinical Trials of Antioxidants to Prevent Neurodegeneration Failed? – A Cellular Investigation of Novel Phenothiazine-Type Antioxidants Reveals Competing Objectives for Pharmaceutical Neuroprotection

Purpose: Only a fraction of the currently established low-molecular weight antioxidants exhibit cytoprotective activity in living cells, which is considered a prerequisite for their potential clinical usefulness in Parkinson?s disease or stroke. Post hoc structure-activity relationship analyses have predicted that increased lipophilicity and enhanced radical stabilization could contribute to such cytoprotective activity. Methods: We have synthesized a series of novel phenothiazine-type antioxidants exhibiting systematic variation in their lipophilicity and radical stabilization. Phenothiazine was chosen as lead structure for its superior activity at baseline. The novel compounds were evaluated for their neuroprotective potency in cell culture, and for their primary molecular targets. Results: Lipophilicity was associated with enhanced cytoprotective activity, but only to a certain threshold (logP ? 7). Benzannulation likewise produced improved cytoprotectants that exhibited very low EC50 values of ~8?nM in cultivated neuronal cells. Inhibition of global protein oxidation was the best molecular predictor of cytoprotective activity, followed by the inhibition of membrane protein autolysis. In contrast, the inhibition of lipid peroxidation in isolated brain lipids and the suppression of intracellular oxidant accumulation were poor predictors of cytoprotective activity, primarily as they misjudged the cellular advantage of high lipophilicity. Conclusions: Lipophilicity, radical stabilization and molecular weight appear to form an uneasy triangle, in which a slightly faulty selection may readily abolish neuroprotective activity.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Recommanded Product: 2-Cyano-phenothiazine, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 38642-74-9, in my other articles.
