Synthesis and antibacterial activity of C4 substituted monobactams
摘要:
The synthesis and antibacterial activity of a series of monobactams having various substituents at C4 position is described. An efficient route to versatile intermediates 4a-c from 6-aminopenicillanic acid (6-APA) has been developed. Derivatives 10e, 11, 21 showed good to moderate activity against Gram-negative bacteria with the exception of Pseudomonas aeruginosa. Introduction of a catechol moiety on the C4 side chain only slightly improved the activity against P aeruginosa.

Novel compounds having a fused bicyclic heteroaromatic ring system substituted with a heteroaryl five-membered ring are disclosed. The compounds inhibit growth of a variety of types of cancer cells, and are thus useful for treating cancer. Efficacy of these compounds is demonstrated with a system for monitoring cell growth/migration, which shows they are potent inhibitors of growth and/or migration of cancer cells. In addition, compounds of the invention were shown to stop growth of tumors in vivo, and to reduce the size of tumors in vivo. Compositions comprising these compounds, and methods to use these compounds and compositions for treatment of cancers, are disclosed.
