A group of glycosphingolipids found in an invertebrate: Their structures and biological significance
A novel group of glycosphingolipids was identified in the nervous tissue and skin of the mollusc, Aplysia kurodai, which lacks gangliosides. More than 30 glycolipids were detected on HPTLC plates and the structures of 9 major glycolipids were determined. They were pentaosylglycosphingolipids and their common core structure was GalNAcα1→3Galβ1→4Glcβ1→1ceramide, except for one glycolipid in which...
متن کاملEfficient total syntheses and biological activities of two teixobactin analogues.
The discovery of the new antibiotic teixobactin has been timely in the race for unearthing novel antibiotics wherein the emergence of drug resistant bacteria poses a serious threat worldwide. Herein, we present the total syntheses and biological activities of two teixobactin analogues. This approach is simple, efficient and has several advantages: it uses commercially available building blocks ...
متن کاملSYNTHESES, ANTIFUNGAL AND ANTIBACTERIAL ACTIVITIES OF SUBSTITUTED 1,2, CTRIMOLES
The reaction of readily available 1 -methyl-4-nitropyrrole-2- carboxylic acid (1) with thionyl chloride afforded the corresponding acyl chloride 2. The reaction of compound 2 with thiosemicarbazides yielded 1-(1 -methyl-4-nitrop yrrole-2-carbony1)- thiosemicarbazides (3) which cyclized in basic medium to 5-(1-methyl-4-nitropyrrole- 2-y1)-2,4-dihydro-3H- l,2,4-triazole-3- thione 4. Alkylatio...
متن کاملEssential Oils from Neotropical Piper Species and Their Biological Activities
The Piper genus is the most representative of the Piperaceae reaching around 2000 species distributed in the pantropical region. In the Neotropics, its species are represented by herbs, shrubs, and lianas, which are used in traditional medicine to prepare teas and infusions. Its essential oils (EOs) present high yield and are chemically constituted by complex mixtures or the predominance of mai...
