In recent years, there have been many publications on the synthesis and study of biological activity, including antitumour activity, of new organo-arsenic compounds. It is known that spatially hindered phenols can also have antitumor activity, so the synthesis and study of hybrid compounds based on organo-arsenic compounds and spatially hindered phenols is a relevant area of research. In this work, the modification of 4-aminophenylarsonic acid with 3,5-di-tert-butyl-4-hydroxybenzylacetate was carried out. In contrast to a similar transformation of 2-aminophenylarsonic acid, in this case it was possible to obtain both mono- and di-benzyl derivatives of the acid. Using the Zandmeyer method, the oxime isatin containing an arsonic acid fragment in the fifth position of the heterocycle was synthesised. Azo derivatives containing fragments of <i>para</i>-aminophenylarsonic acid and sterically hindered phenols were obtained. 4-((3,5-Di-tert-butyl-2-hydroxyphenyl)diazenyl)phenylarsonic acid was isolated in pure form. At the same time, it was found that the reaction of the diazonium azo salt of 4-aminophenylarsonic acid with 2-hydroxymethyl-4-tert-butylphenol proceeds in two directions. In addition to the classical diazotisation reaction at the 6-position of 2-hydroxymethyl-4-tert-butylphenol, a diazotisation accompanied by a dehydroxymethylation process occurs. The obtained compounds showed cytotoxic activity against human tumor cell lines M-HeLa (cervical epithelioid carcinoma) and HuTu 80 (duodenal adenocarcinoma cells). The most promising is the sodium salt of 4-((3,5-di-tert-butyl-2-hydroxyphenyl)diazenyl)phenylarsonic acid, which is superior to Tamoxifen and 5-fluorouracil in terms of selectivity index towards M-HeLa and HuTu 80 cells.</p>","PeriodicalId":529,"journal":{"name":"Doklady Biochemistry and Biophysics","volume":"519 1","pages":"534 - 539"},"PeriodicalIF":0.8,"publicationDate":"2024-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142556862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

STT treatment effectively reversed the TGF-β1 induced increase in expression of LOXL2 protein and phosphorylation of Smad2/3 proteins. Treatment of PLFs with STT reversed the TGF-β1-induced increase in expression of NOX4 and suppression of p-AMPK protein. In mice model of pulmonary fibrosis STT treatment significantly inhibited the BLM-mediated decrease in body weight and survival rate. The BLM induced increase in pulmonary index in mice was also effectively inhibited on treatment with STT. Treatment of the mice with STT inhibited the BLM-induced increase in α-SMA and Col I protein expression in pulmonary tissues. The BLM-induced increase in TGF-β1 protein expression in pulmonary tissues of the mice was inhibited on treatment with STT. Treatment with STT effectively promoted the AMPK activation in lung tissues of the BLM administered mice. In summary, the present study demonstrates that STT treatment prevents TGF-β1 induced up-regulation of α-SMA, collagen I, LOXL2 protein expression and targets phosphorylation of Smad2/3 proteins in PLFs. Moreover, it inhibits TGF-β1-induced increase in expression of NOX4 and reverses TGF-β1-mediated suppression in expression of p-AMPK protein.

The high production of HETEs in allergic and severe asthma indicates their involvement in the processes of an acute inflammatory response.
