benzothiazoles Dotaz Zobrazit nápovědu
Benzothiazole compounds represent heterocyclic systems comprising a benzene ring fused with a thiazole ring containing nitrogen and sulphur in its structure. Besides the presence of a benzothiazole core in naturally occurring molecules, synthesized compounds containing a benzothiazole moiety in their structure proved to be a significant class of potential therapeutics, as they exhibit biological effects such as antitumor, antibacterial, antitubercular, antiviral, anthelmintic, antidiabetic and many others. Apart from the aforementioned peripheral or microbial active sites, benzothiazole analogues are also biologically active compounds in the central nervous system, where some approved drugs containing a benzothiazole moiety have already been identified and are used in the treatment of various neurological disorders. New benzothiazole molecules are currently under development and are being evaluated for several uses including diagnostics and as therapeutic drug candidates for the treatment of epilepsy and neurodegenerative diseases such as Alzheimer's disease, Huntington's disease and amyotrophic lateral sclerosis amongst others.

A set of 1160 minimum inhibitory concentration (MIC) values evaluating effect of substitution on the antimycobacterial activity of the previously published 2-(substituted benzyl)sulfanyl benzimidazoles, benzoxazoles, and benzothiazoles has been analyzed by the methods of multidimensional analysis (exploratory analysis, 2D-nonlinear mapping (NLM), principal component analysis (PCA), factor analysis (FA), multiple linear regression (MLR)). The antimycobacterial activity of 2-(subst. benzyl)sulfanyl derivatives of benzimidazole (BIM), 5-methylbenzimidazole (5-Me-BIM), benzoxazole (BOZ), and benzothiazole (BTZ) increased in the order of BTZ

INTRODUCTION: Benzotriazoles and benzothiazoles (BTs) are high-production volume chemicals as well as widely distributed emerging pollutants with potential health risk. However, information about human exposure to BTs and associated health outcomes is limited. OBJECTIVE: We aimed to characterise exposure to BTs among Czech men, including possible occupational exposure among firefighters, its predictors, and its associations with liver function, serum lipids and oxidative stress. METHODS: 165 participants (including 110 firefighters) provided urine and blood samples that were used to quantify the urinary levels of 8 BTs (high-performance liquid chromatography-tandem mass spectrometry), and 4 liver enzymes, cholesterol, low-density lipoprotein, and 8-hydroxy-2'-deoxyguanosine. Linear regression was used to assess associations with population characteristics and biomarkers of liver function, serum lipids and oxidative stress. Regression models were adjusted for potential confounding variables and false discovery rate procedure was applied to account for multiplicity. RESULTS: The BTs ranged from undetected up to 46.8 ng/mL. 2-hydroxy-benzothiazole was the most predominant compound (detection frequency 83%; median 1.95 ng/mL). 1-methyl-benzotriazole (1M-BTR) was measured in human samples for the first time, with a detection frequency 77% and median 1.75 ng/mL. Professional firefighters had lower urinary 1M-BTR compared to non-firefighters. Urinary 1M-BTR was associated with levels of γ-glutamyl transferase (β = - 17.54%; 95% CI: - 26.127, - 7.962). CONCLUSION: This is the first study to investigate BT exposure in Central Europe, including potentially exposed firefighters. The findings showed a high prevalence of BTs in the study population, the relevance of 1M-BTR as a new biomarker of exposure, and an urgent need for further research into associated adverse health outcomes.

A series of tacrine - benzothiazole hybrids incorporate inhibitors of acetylcholinesterase (AChE), amyloid β (Aβ) aggregation and mitochondrial enzyme ABAD, whose interaction with Aβ leads to mitochondrial dysfunction, into a single molecule. In vitro, several of 25 final compounds exerted excellent anti-AChE properties and interesting capabilities to block Aβ aggregation. The best derivative of the series could be considered 10w that was found to be highly potent and selective towards AChE with the IC50 value in nanomolar range. Moreover, the same drug candidate exerted absolutely the best results of the series against ABAD, decreasing its activity by 23% at 100 μM concentration. Regarding the cytotoxicity profile of highlighted compound, it roughly matched that of its parent compound - 6-chlorotacrine. Finally, 10w was forwarded for in vivo scopolamine-induced amnesia experiment consisting of Morris Water Maze test, where it demonstrated mild procognitive effect. Taking into account all in vitro and in vivo data, highlighted derivative 10w could be considered as the lead structure worthy of further investigation.
