Abstract Protoberberine alkaloids and related compounds represent an important class of molecules and have attracted recent attention for their various pharmacological activities. This chapter deals with the physicochemical properties of several isoquinoline alkaloids (berberine, palmatine and coralyne) and many of their derivatives under various environmental conditions. The interaction of these compounds with polymorphic DNA structures (B-form, Z-form, H -form, protonated form, triple helical form and quadruplex form) and polymorphic RNA structures (A-form, protonated form, triple helical form and quadruplex form) reported by several research groups, employing various analytical techniques such as spectrophotometry, spectrofluorimetry, circular dichro-ism, NMR spectroscopy, viscometry as well as molecular modelling and thermodynamic analysis to elucidate their mode and mechanism of action for structure-activity relationships, are also presented. [Pg.156]

The chemistry of Reissert compounds has been the subject of numerous general reviews (3-10). In 1973 Popp gave a summary on the use of Reissert compounds in the synthesis of isoquinoline alkaloids and related compounds (7). We now wish to summarize new results that have appeared from 1973 to the end of 1985 for the application of Reissert compounds in the synthesis of isoquinoline as well as indole alkaloids. [Pg.2]

The formation of a Reissert anion (intermediate of type 16) is usually the introductory step in a great number of synthetic routes leading to isoquinoline as well as indole alkaloids and related compounds. On the one hand, the alkylation of a Reissert anion with alkyl halide followed by alkaline hydrolysis is the most frequently used method for the synthesis of 1-alkyl- or 1-arylalkylisoquinolines (20) (Scheme 4). On the other hand, Reissert anions react with aldehydes to form... [Pg.3]

During studies on the synthesis on vinca alkaloids and related compounds it was found that (-)-criocerine 1 and a number of analogues underwent smooth dimerisation when dissolved in acetic acid at room temperature for 24 hours. Thus, 1 gave 2 in 86% yield. [Pg.13]

A continuous series of very excellent reviews on marine natural products by D. J. Faulkner has appeared in Natural Products Reports (2-6), covering all aspects of the literature on marine natural products, organized phylogenetically. Excellent reviews on Marine Alkaloids and Related Compounds (7) and Recent Developments in the Field of Marine Natural Products with Emphasis on Biologically Active Compounds (5) were written by W. Fenical and H. C. Krebs, respectively. Besides these reviews, numerous books dealing with general or specialized topics in marine natural products research have appeared in recent years (9-13). Biosynthetic studies on marine natural products were recently reviewed by M. J. Garson (14). [Pg.42]
