Abstract

The present invention relates to novel semisynthetic macrolides with anti-inflammatory activity. More specifically, the present invention relates to 14- and 15-membered macrolides substituted at the 4" position, their pharmaceutically acceptable derivatives, their preparation methods and intermediates, pharmaceutical compositions containing them and Their activity and use in the treatment of inflammatory diseases and conditions in humans and animals, especially those associated with excessive secretion of TNF-alpha, IL-1, IL-8, IL-2 or IL-5; and / or for use as Activity and uses of inhibitors of lymphocyte hyperproliferation and / or granulocyte degranulation.

Description

[0001] This application claims the priority of U.S. Provisional Application No. 60 / 643,841 filed on January 13, 2005 and U.S. Provisional Application 60 / 715,828 filed on September 9, 2005, the entire contents of which are hereby incorporated by reference. Invention field [0002] The present invention relates to substituted macrolides with anti-inflammatory activity, and pharmaceutically acceptable derivatives thereof and methods of use. [0003] technical problem [0004] The purpose of the present invention is to solve the technical problems brought about by providing new targeted anti-inflammatory drugs. More specifically, the present invention provides anti-inflammatory agents in which the active substance is neither a steroid nor an NSAID. The compound of the present invention can overcome the above-mentioned problems by virtue of its anti-inflammatory activity and accumulation ability in various immune cells recruited to the site of inflammation. Background of the invention ...
