On the Surface Reactivity of Functionalized Phosphinines on Inorganic Supports
Phosphinines with pendant phenol or catechol functionalities and their gold(I) complexes were synthesised and characterised by spectroscopic data and in one case by a single-crystal X-ray diffraction study. Reactions of ligands or complexes with TiO2 or chloropropyl modified hexagonal mesoporous silica were then studied with the aim to immobilise ligands or complexes on the carrier by covalent tethering

The present invention relates to chalcone and chalcone derivatives and analogs which are useful as angiogenesis inhibitors. The present compounds, which are inexpensive to synthesize, exhibit unexpectedly good activity as angiogenesis inhibitors. The present invention also relates to the use of chalcone and its analogs as antitumor/anticancer agents and to treat a number of conditions or disease states in which angiogenesis is a factor, incluidng angiongenic skin diseases such as psoriasis, acne, rosacea, warts, eczema, hemangiomas, lymphangiogenesis, among numerous others, as well as chronic inflammatory disease such as arthritis.
