- PROSTATE SPECIFIC MEMBRANE ANTIGEN (PSMA) TARGETED NANOPARTICLES FOR THERAPY OF PROSTATE CANCER
-
The invention provides a nanoparticle composition that is decorated with a urea-based small-molecule peptidomimetic inhibitor of prostate specific membrane antigen (PSMA), which is expressed by almost all solid tumors. This strategy takes advantage of both the avidity of the functionalized nanoparticle for binding to PSMA and the ability of the nanoparticle to be retained for longer periods of time in the tumor due to enhanced leakage via EPR into the tumor interstitium and poor clearance due to underdeveloped or non-existent lymphatics within the tumor.

- FLAVONOID DIMERS AND METHODS OF MAKING AND USING SUCH
-
Multidrug resistance (MDR) is a major problem in cancer chemotherapy. The best characterized resistance mechanism is the one mediated by the over- expression of drug efflux transporters, permeability-glycoprotein (P-gp), which pump a variety of anticancer drugs out of the cells, resulting in lowered intracellular drug accumulation. A series of flavonoid dimers are developed in this invention, which are linked together by linker groups of various lengths. These flavonoid dimers are found to be efficient P-gp modulators that increase cytotoxicity of anticancer drugs in vitro and dramatically enhance their intracellular drug accumulation. It is found that the flavonoid dimers of this invention is also useful in reducing drug resistance in treating parasitic diseases.

- DENTRITIC POLYMERS, CROSSLINKED GELS, AND THEIR USES IN ORTHOPEDIC APPLICATIONS
-
The present invention provides compositions, kits, and methods for repairing cartilaginous tissue. Certain methods of the invention utilize dendritic macromolecules formed by treating a dendritic compound with light or a linking compound. In certain instances, the dendritic compounds have a lysine, cysteine, isocysteine residue or other nucleophilic group attached to their peripheries. Addition of a compound containing two or more electrophilic groups, such as aldehydes, activated esters, or acrylates, to the lysine-capped, cysteine-capped, or isocysteine-capped dendrimers produces a polymeric compound that can repair a cartilage defect.
