Novel nonsteroidal ligands with high binding affinity and potent functional activity for the androgen receptor
摘要:
While nonsteroidal androgen receptor (AR) antagonists have been known for many years, and used in the clinic for the treatment of hormone dependent prostate cancer, very little is known about nonsteroidal AR agonists. We designed and synthesized a series of chiral bicalutamide analogs, which bear electron-withdrawing groups (either a cyano or a nitro group at the 4-position and a trifluoromethyl group at the 3-position) in the aromatic A ring, and different substituents at the para position in the aromatic B ring of the parent molecule. We also synthesized a series of racemic bicalutamide analogs, which have a trifluoromethyl group instead of a methyl group at the R, position. We examined AR binding affinities of our compounds in a competitive binding assay with a radiolabeled high affinity AR ligand, H-3-mibolerone, and also measured their abilities to stimulate AR-mediated transcriptional activation in a cotransfection assay. These studies demonstrated that (1) nonsteroidal ligands can be structurally modified from known nonsteroidal antiandrogens to generate, ligands capable of activating AR-mediated transcriptional activation. (2) R-isomer analogs exhibit higher AR binding affinity and more potent functional activity than their corresponding S-isomers in all cases. (3) All sulphide analogs show higher AR binding affinity and more potent functional activity than their corresponding sulphone analogs, with the exception of ligand R-8. Those ligands which exhibit high AR binding affinity and potent functional activity for human AR may provide effective clinical uses for male fertility, male contraception, and hormone replacement therapy.

SUMMARY The invention provides a therapy for lysosomal storage diseases and glycogenosis by treatment with compounds that promote exocytosis, preferably lysosomal exocytosis. The treatment of cells from patients affected by different lysosomal storage disorders with exocytosis activating compounds leads to a decrease in the accumulation of toxic substrate in the lysosomes, thus allowing the treatment, prevention and relief of the symptoms of many lysosomal storage disorders.
