- Absorption medium and method for removing sour gases from fluid streams, in particular from flue gases
-
Absorption medium for acid gases comprising an oligoamine (A) of the general formula (I) and a primary or secondary alkanolamine (B) of the general formula (II) in which the weight ratio of oligoamine (A) to the primary or secondary alkanolamine (B) is 0.2 to 4, and also the process for removing acid gases from a gas stream by contacting the gas stream at a pressure of 0.05 to 10 MPa abs with an aqueous solution brought to and maintained at a temperature of 20 to 80° C. of said absorption medium.

- NOVEL ALIPHATIC COMPOUND, METHOD OF SYNTHESIS, AND METHOD OF UTILIZATION
-
The present invention relates to aliphatic compounds of the formula I, or stereoisomers thereof, or their pharmaceutically acceptable salts: wherein A represents an optionally substituted CH3CnH(2n-2m)- (wherein n denotes an integer of 4 to 22, and m represents an unsaturation number which is an integer of 0 to 7), 1 represents an integer of 0 to 10, s represents 0 or 1, provided that when s is 0, p+q = 4 or 5, but when s is 1, p+q = 3 or 4, and in each case, either p or q is an integer of 1 or more, R represents an alkyl group having 1 to 10 carbon atoms which may be straight-chain or branched-chain, and RA represents hydrogen or an alkyl group having 1 to 10 carbon atoms which may be straight-chain or branched-chain, and their use in suppression of platelet aggregation, in suppression of inflammation, and in prevention and treatment of circulatory diseases.

- A new class of histamine H3-receptor antagonists: Synthesis and structure - Activity relationships of 7,8,9,10-Tetrahydro-6H-cyclohepta[b]quinolines
-
The synthesis and biological evaluation of novel cycloheptaquinoline antagonists of the human H3 receptor are described. Two series of compounds, bearing either an amino substituent or an alkyne linker at the 11-position, were investigated. Modifications of the amino substituents, optimization of chain length and the effect of conformational restraints are described. Several compounds with high affinity and selectivity for the H3 receptor were discovered.
