The invention relates to plasminogen activator-1 (PAI-1) inhibitor compounds and uses thereof in the treatment of any disease or disorder associated with elevated PAI-1. The invention includes, but is not limited to, the use of such compounds to prevent or reduce thrombosis and fibrosis, to promote thrombolysis, and to modulate lipid metabolism and treat diseases or disorders associated with elevated PAI-1, cholesterol, or lipid levels.

Non-lactone carbocyclic and heterocyclic antagonists and agonists of bacterial quorum sensing. Pharmaceutical composition containing antagonists. Methods employing antagonists and agonists for modulation of quorum sensing. Compounds are exemplified by those of formula:
A-[Z].sub.n-L1-[Y].sub.q-W-[V].sub.m-L2-HG,
where A is an acyclic aliphatic group, and HG is an optionally substituted phenyl group. Compounds include those where m and n are both 0, W is —NH—, Y is present and is —CO—CH.sub.2—CO—, and L1 and L2 independently are —[CH.sub.2].sub.p1— and —[CH.sub.2].sub.p2—, where p1 and p2, independently, are 0 or integers ranging from 1-10.

The present invention relates to dicaffeoyl spermidine derivative glycosides, a preparation method and a use thereof. The biological activity experiments show that the dicaffeoyl spermidine derivative glycosides of the present invention have anti-oxidative activity and antiviral activity, and their activity are even better than that of a positive control drug, thus can be used as an antioxidant for the prevention and/or treatment of neurodegenerative diseases such as Senile dementia, and as an antiviral agent for the prevention and/or treatment of viral infections.
