Publication number: 20140357682Abstract: Non ligand binding pocket antagonists for the human androgen receptor. The androgen receptor (AR) is a member of the Nuclear Receptor (NR) family and its role is to modulate the biological effects of the endogenous androgens, testosterone (tes) and dihydrotestosterone (DHT). Synthetic androgens and anti-androgens have therapeutic value in the treatment of various androgen dependent conditions, from regulation of male fertility to prostate cancer. Current treatment of prostate cancer (PCa) typically involves administration of ‘classical’ antiandrogens, competitive inhibitors of natural AR ligands, DHT and tes, for the ligand binding pocket (LBP) in the C-terminal ligand binding domain (LBD) of the AR. However, prolonged LBP-targeting can often lead to androgen resistance and alternative therapies and therapeutic strategies are urgently required. Disclosed herein are a class of non-steroidal, small molecule AR antagonists which inhibit the transcriptional activity of the AR by non LBP-mediated modulation.Type: ApplicationFiled: November 23, 2012Publication date: December 4, 2014Applicant: THE PROVOST, FELLOWS, FOUNDATION SCHOLARS, & THE OTHER MEMBERS OF BOARD, OF THE COLLEGE OF THE HOLYInventors: David George Lloyd, Darren Fayne, Mary Jane Meegan, Miriam Carr, Gemma Karena Kinsella, Laura Caboni, Wiliam Nicholas Jagoe, Billy Egan, Fernando Blanco

Patent number: 8791299Abstract: 3D protein modeling and virtual screening of commercially-available compounds were performed to identify new inhibitors of the herpesvirus DNA polymerase, a key enzyme in the viral replication cycle. Two compounds (Nos 2 and 9) were particularly active against HSV-1 and HSV-2 strains and one compound (No 3) inhibited specifically cytomegalovirus (CMV) strains (overall hit rate of 25%). Some of the tested compounds inhibited wild-type viruses and strains resistant to current antiviral agents. New chemical entity derivatives of compound 2 with binding potential to the DNA polymerase retained an excellent activity against HSV-1, HSV-2 and VZV like the parental compound, as well against strains resistant to current antiviral agents.

Publication number: 20120157687Abstract: A process is described for the preparation of arylpyridine compounds by aryl-aryl cross-coupling reactions between a halopyridine and an arylmagnesium halide carried out in the presence of a catalytic amount of a zinc salt and a catalytic amount of palladium complex with a bidentate phosphine. The zinc salt is preferably selected from ZnCl2, ZnBr2 and/or Zn(OAc)2, while the palladium complex with a bidentate phosphine is preferably selected from the group of (1,2-Bis(diphenylphosphino)ethane)palladium(II) chloride, (1,3-Bis(diphenylphosphino)propane)palladium(II) chloride and (1,4-Bis(diphenylphosphino)butane)palladium(II) chloride. Most preferred is (1,2-Bis(diphenylphosphino)ethane)palladium(II) chloride. It is thus possible to obtain molar yields higher than 95% calculated on the arylmagnesium halide and a catalyticity less than 1:1500.Type: ApplicationFiled: June 24, 2010Publication date: June 21, 2012Applicant: PRIME EUROPEAN THERAPEUTICALS S.P.A.Inventors: Roberto Scrocchi, Fedeli Palma, Argese Maria, Guazzi Giuseppe
