Design, Synthesis, and Biological Evaluation of New Cinnamic Derivatives as Antituberculosis Agents
摘要:
Tuberculosis, HIV coinfection with TB, emergence of multidrug-resistant TB, and extensively drug-resistant TB are the major causes of death from infectious diseases worldwide. Because no new drug has been introduced in the last several decades, new classes of molecules as anti-TB drugs are urgently needed. Herein, we report the synthesis and structure-activity relationships of a series of thioester, amide, hydrazide, and triazolophthalazine derivatives of 4-alkoxy cinnamic acid. Many compounds exhibited submicromolar minimum inhibitory concentrations against Mycobacterium tuberculosis strain (H(37)Rv). Interestingly, compound 13e, a 4-isopentenyloxycinnamyl triazolophthalazine derivative, was found to be 100-1800 times more active than isoniazid (INH) when tested for its ability to inhibit the growth of INH-resistant M. tuberculosis strains. The results also revealed that 13e does not interfere with mycolic acid biosynthesis, thereby pointing to a different mode of action and representing an attractive lead compound for the development of new anti-TB agents.

The present invention relates to new cinnamic add amides which may be used for treatment of fibrosis and neoplasia and to cinnamic acid amides for use in the treatment of fibrosis, neoplasia, arthrolithiasis, familiar mediterranean fever and pericarditis. Further, the invention relates to a pharmaceutical composition comprising said cinnamic acid amides and to a screening essay for identifying compounds suitable for the treatment of fibrosis.
