Polymer conjugates characterized in that the backbone of the polymer is an anionic polymer and hydrophobic moieties are covalently attached to the polymer backbone are useful for preparing drug encapsulated polymer hydrotropes and compositions. Such materials are useful in methods for delivering the drug into cells, and for the treatment and alleviation of diseases and disorders such as cancer.
Various biodegradable polyglutamate-amino acids comprising recurring units of the general formulae (I) and (II) are prepared. Such polymers are useful for variety of drug, biomolecule and imaging agent delivery applications.

Some of them are naturally occurring flavor enhancers or are endowed with biological activities.

Novel efficient, time-saving and reliable radiofluorination procedures for the production of 18F-labelled active esters via nucleophilic substitution of the corresponding onium precursors with 18F- are described. The active ester including [18F]F-Py-TFP and [18F]TFB produced by one of these methods was used to prepare PSMA-specific PET tracers such as [18F]DCFPyL. The key advantages of these inventive methods are efficiency, short time of preparation and excellent amenability to automation. A pharmaceutical composition containing at least one PSMA-specific PET tracers prepared by the inventive method is useful for positron emission tomography (PET) imaging, especially imaging prostate tumor.
