Filed:

Nov 26, 2003

Appl. No.:

10/723744

Inventors:

Hugo Camenzind - Bern, CH
Paul Dubs - Cham, CH
Roger Martin - Rheinfelden, CH
David Eliezer Chasan - Teaneck NJ, US
Gunnar Demme - Mahopac NY, US
James Robbins - Satsuma AL, US

Assignee:

Ciba Specialty Chemicals Corp. - Tarrytown NY

International Classification:

C08G 63/688
C08G 75/00

US Classification:

528360, 528361, 528364, 528373, 524292, 524386, 560 60, 252404

Abstract:

The invention relates to liquid sulphur-containing antioxidants and to compositions comprising them. The novel lubricant compositions comprise the reaction product of a selected group of 5-tert-butyl-4-hydroxy-3-methyl(or tert-butyl)phenyl substituted carboxylic acid esters with thiodiethylene glycol and a mono-hydroxy alcohol with a carbon chain length higher than 4 C-atoms. The novel lubricant compositions are highly resistant to oxidative degradation and are capable of reducing the negative effects of deposits, such as black sludge, in motor combustion engines, particularly spark ignition internal combustion engines.

Abstract:

Cell-specific ligands comprising conjugates of saccharides and amino acids or peptides are synthesized from amino acids such as ornithine, lysine, peptides such as dilysine, diornithine or oligolysine and selected saccharides having reactive functional groups protected by appropriate blocking groups. Such glycopeptides are useful as tissue specific substances, which when coupled with bioactive materials through metabolizable or hydrolyzable linkages, deliver such bioactive materials to the selected site. In this manner, antiinflammatory drugs such as dexamethasone are linked through a metabolizable or hydrolyzable linkage and on administration to an animal suffering from inflammatory disease carries the drug to the site of inflammation for intracellular release. Other examples include the macrophage ligand N. sup. 2 -N. sup. 2, N. sup. 6 -Bis-[3-(. alpha.
