3-Trifluoromethylcarbacephems: Synthesis of broad spectrum antibacterial compounds
摘要:
The enhanced stability of the carbacephem nucleus over the corresponding cephalosporin nucleus has allowed the synthesis of 7-arylglycyl-3-trifluoromethyl-carbacephems. These unique carbacephems possess broad spectrum activity and high stability to both plasmid and chromosomally mediated beta-lactamases. (C) 1998 Elsevier Science Ltd. All rights reserved.
The present invention relates to compounds of the formula
which are useful in treating diseases characterized by the hyperactivity of MEK. Accordingly the compounds are useful in the treatment of diseases, such as, cancer, cognative and CNS disorders and inflammatory/autoimmune diseases.
