Abstract: The present invention relates to novel semi-synthetic macrolides having anti-inflammatory activity. More particularly, the invention relates to 14- and 15-membered macrolides substituted at the 4? position, to their pharmaceutically acceptable derivatives, to processes and intermediates for their preparation, to pharmaceutical compositions containing them and to their activity and use in the treatment of inflammatory diseases and conditions in humans and animals, especially those diseases associated with excessive secretion of TNF-?, IL-1, IL-8, IL-2 or IL-5; and/or inhibitor of excessive lymphocyte proliferation; and/or excessive granulocyte degranulation.

Abstract: Certain bis-(coumarin) compounds as well as the products of their intramolecular cyclization including pharmaceutically acceptable salts, hydrates, solvates, clathrates, prodrugs, tautomers and stereoisomers thereof are disclosed. Certain processes and intermediates for the preparation of certain bis-(coumarin) compounds, as well as for the use of these compounds as therapeutically active agents in the prophylaxis and treatment of asthma and other inflammatory diseases and conditions in mammals, especially humans are also disclosed.
