A novel and efficient heterogeneous catalyst SiO2-tpy-Nb was developed, and its application in the preparation of N-substituted phthalimides from o-phthalic acids or anhydrides with amines provides the desired products in good to excellent yields. The catalyst was stable and recoverable for eight consecutive cycles without a significant loss in its activity. Furthermore, the catalyst is applicable

A series of compounds originally derived from thalidomide were synthesized and evaluated. The most potent compounds in this series, 5HPP-33 and compound 20, inhibited NF-kappaB activation in HeLa cells. Preliminary study indicated that the mechanism of inhibition of NF-kappaB activation is through inhibition of its translocation from the cytoplasm to the nucleus.

Novel methods are provided to prevent blindness associated with diabetic macular edema by administration of a phenylphthalimide analog. Additionally, sustainability of the effect of administration of the phenylphthalimide analog is improved via encapsulation with poly(lactic-co-glycolic acid) nanoparticles. Finally, a novel method for synthesizing (2,6-diisopropylphenyl)-5-amino-1H-isoindole-1,3-dione is disclosed.
