Bromine-and chlorine-containing aeruginosins from microcystis aeruginosa bloom material collected in Kibbutz Geva, Israel

Five new natural products, aeruginosins GE686 (1), GE766 (2), GE730 (3), GE810 (4), and GE642 (5), were isolated along with four known aeruginosins, 98C, 101, KY642, and DA688, from bloom material of the cyanobacterium Microcystis aeruginosa collected from a fish pond in Kibbutz Geva, Israel, in August 2007. Their structures were elucidated by a combination of various spectroscopic techniques, primarily NMR and MS, while the absolute configurations of the stereogenic centers were determined by Marfey's and chiral-phase HPLC methods. Two of the new aeruginosins, aeruginosins GE686 (1) and GE766 (2), contain the unprecedented d-m-Br-m′-Cl-p-hydroxyphenyllactic acid derivative. The structures and biological activities of the five new metabolites are described.

2-OXO-1,2,4,5-TETRAHYDRO-1,3-BENZODIAZEPIN-3-YL-PIPERIDINES USED AS CGRP ANTAGONISTS

The invention relates to novel CGRP antagonists of general formula (I), in which B, R1 and R2 are defined as cited in claim 1, to their tautomers, isomers, diastereomers, enantiomers, hydrates, mixtures and salts, in addition to the hydrates of their salts, in particular their physiologically compatible salts, with inorganic or organic acids or bases. The invention also relates to medicaments containing said compounds, to their use and to a method for their production.

CGRP ANTAGONISTS, METHOD FOR THE PRODUCTION THEREOF, AND THEIR USE AS MEDICAMENTS

The invention relates to CGRP antagonists of general formula (I) in which: R1, R2, R3, R4 and X are defined as in Claim 1, to their tautomers, isomers, diastereomers, enantiomers, hydrates, mixtures and salts as well as the hydrates of the salts, in particular, their physiologically compatible salts with inorganic or organic acids and bases, and those compounds of general formula (I) in which one or more hydrogen atoms are replaced by deuterium. The invention also relates to medicaments containing these compounds, the use thereof, and to methods for producing them.

SELECTED CGRP ANTAGONISTS, METHODS FOR THE PRODUCTION THEREOF AND THEIR USE AS MEDICAMENTS

The invention relates to CGRP antagonists of general formula (I), in which A, X, D, E, G, M, Q and R1 to R3 are defined as in Claim 1, to their tautomers, isomers, diastereomers, enantiomers, hydrates, mixtures and their salts as well as the hydrates of the salts, particularly their physiologically compatible salts having inorganic or organic acids, to medicaments containing these compounds, to their use, and to methods for the production thereof.
