- RGD-peptides modifying dexamethasone: to enhance the anti-inflammatory efficacy and limit the risk of osteoporosis
-
Dexamethasone (Dex) is one of the most effective anti-inflammatory glucocorticoids, while the side effect, osteoporosis seriously limits its clinical use. Cell adhesion is involved in the onset of inflammation and osteoporosis, and RGD-peptides are well k

- Dual-acting agents that possess free radical scavenging and antithrombotic activities: Design, synthesis, and evaluation of phenolic tetrahydro-β-carboline RGD peptide conjugates
-
A new approach to construct a single dual-acting agent is described. Compounds 6a-c are potent free radical scavengers as demonstrated by the EC50 values in PC12 cell survival assay in term of NO, H2O2, and {radical dot}OH scavenging activity. The Ach-induced vaso-relaxation assay further confirms the potent NO scavenging activity of compounds 6a-c. In addition, 6a-c are efficacious in a rat arterial thrombosis, and are active in ADP- or PAF-induced in vitro platelet aggregation assay, suggesting that compounds 6a-c also possess anti-thrombotic activities. Since both free radical and thrombogenesis are important risk factors in myocardial ischemic/reperfusion injuries, these dual-acting agents having both free radical scavenging and antithrombolic activities may potentially be beneficial toward their treatment.

- Fibrinogen-coated particles for therapeutic use
-
The invention provides a particle comprising fibrinogen bound on the surface of an albumin matrix, wherein said particle is capable of coaggregation with platelet, and of aggregation in a solution containing soluble fibrinogen at a concentration of soluble fibrinogen not capable by it self of formation of a clot upon activation by thrombin.

- Non-crosslinked protein particles for therapeutic and diagnostic use
-
Albumin particles in the nanometer and micrometer size range in an aqueous suspension are rendered stable against resolubilization without the aid of a crosslinking agent and without denaturation, by the incorporation of a stabilizing agent in the particle composition. Particles which are primarily albumin in the nanometer and micrometer size range in an aqueous suspension are rendered stable against resolublization by the incorporation of a reducing agent, oxidizing agent, hydrogen-accepting molecule, high molecular weight polymer, sulfur-containing ring compound or combinations thereof.

- Non-crosslinked protein particles for therapeutic and diagnostic use
-
Albumin particles in the nanometer and micrometer size range in an aqueous suspension are rendered stable against resolubilization without the aid of a crosslinking agent and without denaturation, by the incorporation of hemoglobin in the particle composition. Particles which are primarily hemoglobin in the nanometer and micrometer size range in an aqueous suspension are rendered stable against aggregation by the incorporation of either albumin, surface active agents or gelatin.
