Synthesis and analysis of some bis-heterocyclic compounds containing sulphur.
A facile and convenient synthesis of a series of bisheterocycles 7a,b 10, 12 and 13a,b containing a thieno[2,3-b]thiophene base unit via the versatile, hitherto unreported 3-[3,4-dimethyl-5-(3-nitrilopropanoyl)thieno[2,3-b]thiophen-2-yl]-3-oxopropanenitrile (4) is described.
متن کاملCarbohydrates and sulphur-containing compounds in the anaemic buccal epithelium.
Mucosal biopsies from the inside of the cheek show epithelial atrophy, glycogen depletion, and an occasional increase in sulphydryl content in both iron-deficiency and megaloblastic anaemias. These changes are the same in the two types of anaemia but are more marked in the latter group.
متن کاملSynthesis, reactions and biological activity of some new bis-heterocyclic ring compounds containing sulphur atom
BACKGROUND The derivatives of thieno[2,3-b]thiophene belong to a significant category of heterocyclic compounds, which have shown a wide spectrum of medical and industrial application. RESULTS A new building block with two electrophilic center of thieno[2,3-b]thiophene derivatives 2 has been reported by one-pot reaction of diketone derivative 1 with Br2/AcOH in excellent yield. A variety of h...
متن کاملBiofiltration of reduced sulphur compounds and community analysis of sulphur-oxidizing bacteria.
The present work aims to use a two-stage biotrickling filters for simultaneous treatment of hydrogen sulphide (H(2)S), methyl mercaptan (MM), dimethyl sulphide (DMS) and dimethyl disulphide (DMDS). The first biofilter was inoculated with Acidithiobacillus thiooxidans (BAT) and the second one with Thiobacillus thioparus (BTT). For separate feeds of reduced sulphur compounds (RSC), the eliminatio...
متن کاملSulphur by-product: the relationship between volatile sulphur compounds and dental plaque-induced gingivitis.
The purpose of this study was to evaluate the relationship between volatile sulphur compounds (VSC) and gingival health status, and to monitor the changes in VSC in early dental plaque-induced gingivitis. Using an experimental gingivitis model, twelve subjects between 19 and 28 years old, with a healthy gingival status, refrained from brushing and flossing one randomly selected half of the mand...
