Embodiments described herein are directed to oligomeric phosphonates and polyphosphonates that have non-reactive end groups, methods for making such oligomeric phosphonates and polyphosphonates, and compositions containing such oligomeric phosphonates and polyphosphonates. The oligomeric phosphonates and polyphosphonates of such embodiments may be incorporated into engineering polymeric into which they are mixed to make polymer compositions having good flame retardancy and mechanical properties.

Described herein is a degradable linking agent of formula Photo.sup.1-LG-Photo.sup.2, wherein Photo.sup.1 and Photo.sup.2 independently represent at least one photoreactive group and LG represents a linking group comprising one or more silicon atoms or one or more phosphorous atoms. The degradable linking agent includes a covalent linkage between at least one photoreactive group and the linking group, wherein the covalent linkage between at least one photoreactive group and the linking group is interrupted by at least one heteroatom. A method for coating a support surface with the degradable linking agent, coated support surfaces and medical devices are also described.

Methods and compounds are disclosed for treating a disease or condition by inhibiting PSMA (Prostate Specific Membrane Antigen) using prodrugs of 2-PMPA.

This disclosure relates generally to cannabinoid derivatives, pharmaceutical compositions comprising them, and methods of using the cannabinoid derivatives.
