Astonishing diversity of natural surfactants: 6. Biologically active marine and terrestrial alkaloid glycosides

Abstract

This review article presents 209 alkaloid glycosides isolated and identified from plants, microorganisms, and marine invertebrates that demonstrate different biological activities. They are of great interest, especially for the medicinal and/or pharmaceutical industries. These biologically active glycosides have good potential for future chemical preparation of compounds useful as antioxidants, anticancer, antimicrobial, and antibacterial agents. These glycosidic compounds have been subdivided into several groups, including: acridone; aporphine; benzoxazinoid; ergot; indole; enediyne alkaloidal antibiotics; glycosidic lupine alkaloids; piperidine, pyridine, pyrrolidine, and pyrrolizidine alkaloid glycosides; glycosidic quinoline and isoquinoline alkaloids; steroidal glycoalkaloids; and miscellaneous alkaloid glycosides.

Thermotropic and lyotropic liquid crystalline phases of Guerbet branched-chain -D-glucosides

“…A series of reviews by Dembitsky shows the astonishing structural diversity of natural glycolipids and, despite being only a minor component in biological membranes of animal cells, the presence of glycolipids in nature is pervasive [1][2][3][4][5][6][7]. This strongly suggests that their importance is no less than that of the major membrane lipid components such as phospholipids.…”

Bioactive cyclobutane-containing alkaloids

“…The cyclobutane unit is found as a basic structural element in a wide range of naturally occurring compounds in bacteria, fungi, plants, and marine invertebrates. It is also generated transiently in primary and secondary metabolisms [1][2][3]. Many biological activities are shown and may serve as potential drug leads or provide new ideas for the study of enzyme mechanisms and/or organic synthesis [4].…”
