Substituted phenylalanines are provided comprising an hydantoin, urea or 2-hydroxyl, 2-methylpropionyl group, dimers thereof and alkyl, polyfluoroamido and haloarylamino derivatives thereof, as well as radiolabeled derivatives thereof. The compounds bind specifically to the androgen receptor and find use in the therapy of indications associated with the androgen receptor, such as, hirsutism, acne and androgenetic alopecia, and in the therapy and diagnosis of cell hyperplasia dependent on androgens.

Androgen receptor suppressors in the therapy and diagnosis of prostate cancer, alopecia and other hyper-androgenic syndromes

Novel polymeric biologically inert compositions and their intermediates, as well as sunscreen formulations comprising them and making them invisible, are provided for broad range protection from ultraviolet radiation. Acryl polymers comprising at least two different ultraviolet absorbing moieties having different light absorbing ranges are employed in conjunction with other monomers to provide sunscreen polymers as microparticles. The polymer microparticles, once imbibed with carrier compounds, change the refractive index, thus providing invisible sunscreen formulations which offer enhanced protection without adverse physiological effects.

Sunblocking polymers and their novel formulations

Novel non-ionic contrast media are provided, which fulfill the requirements for x-ray visualization media, while being biodegradable. The compounds are characterized by being triiodo-3,5-diaminobenzoic acid derivatives, where the functional groups are derivatized with hydroxyalkyl groups and the amino functionalities are further derivatized with acyl substituents of one carbon acids. Also, triiodophloroglucinol oxyalkyl substituted derivatives are provided.

Biodegradable nonionic contrast media

Novel taxoids are provided having enhanced water solubility and/or improved pharmacological properties as compared to paclitaxel. The subject taxoids comprise a functional group attached to a paclitaxel at the C-2' and/or C-7 position by a linking group. Functional groups present in the subject taxoids may be hydrophilic chains, groups capable of in vivo conversion to hydrophilic chains, targeting moieties capable of specifically binding with cellular receptors and water soluble polymers of at least 5 kD. The subject taxoids find use in the treatment of hosts suffering from a cellular proliferative disease.

Taxoids

Novel polymeric compositions and their intermediates are provided, providing for broad range protection from ultraviolet radiation. Acryl polymers comprising at least two different ultraviolet absorbing moieties having different light absorbing ranges are employed in conjunction with another hydrophilic monomer to provide sunscreen formulations for invisibility, and enhanced protection, without deleterious effects in the dermis.

Sunblocking polymers and their formulation

Substituted phenylthiohydantoins are provided for use in detecting the presence of tumor cells having androgenic receptors and providing for cytostatic and cytotoxic activity toward such cells. The subject compounds provide for vehicles for specific targeting to the androgenic receptor containing cells of cytostatic and/or cytotoxic agents, heavy or light radioactive or radioopaque atoms, and the like for detection and treatment of cancer cells involving androgenic receptors or blocking androgenic receptors.
