The present invention generally relates to new compounds for therapeutic uses. In particular, the disclosed series compounds with immunomodulatory activities are useful for treatment of dysfunctions of the immune system and various cancers. Pharmaceutical composition matters and methods for treating a patient with an immune disease and/or a cancer by administering therapeutically effective amounts of such compound alone or together with other therapeutics are within the scope of this disclosure.

The present invention relates to monobactam compounds of Formula I:

##STR00001##

and pharmaceutically acceptable salts thereof. The present invention also relates to compositions which comprise a monobactam compound of structural formula I or a pharmaceutically acceptable salt therof, and a pharmaceutically acceptable carrier. The invention further relates to methods for treating a bacterial infection comprising administering to the patient a therapeutically effective amount of a compound of structural formula I, either alone or in combination with a therapeutically effective amount of a second beta-lactam antibiotic.
