  Nonpeptide Somatostatin Agonists with sst₄ Selectivity:  Synthesis and Structure−Activity Relationships of Thioureas

  摘要：

  Utilizing NNC 26-9100 (11) as a structural lead, a variety of nonpeptide derivatives of somatostatin were synthesized and evaluated for sst(2) and sst(4) receptor binding affinity. A novel thiourea scaffold was utilized to attach (1) a heteroaromatic nucleus to mimic the Trp(8) residue, (2) a nonheteroaromatic nucleus to mimic Phe(7), and (3) a primary amine or other basic group to mimic the Lys(9) residue of somatostatin. Displacement studies were carried out using membranes from cell lines expressing ssts [BHK cells (sst(4)) and HEK 293 cells (sst(2))] utilizing [I-125]Tyr(11)-SRIF as the radioligand. Several thioureas (11, 38, 39, 41, and 42) and the urea 66 exhibited K-i values of less than 100 nM. The thioureas 11 (K-i = 6 nM) and 41 (K-i = 16 nM) and the urea 66 (K-i = 14 nM) are believed to be the most potent nonpeptide sst(4) agonists known. Since the thiourea 11 and the urea 66 exhibit high ssts selectivity, these novel nonpeptide derivatives may be useful tools for studying the sst(4) receptor. Studies are currently in progress to evaluate the therapeutic potential of NNC 26-9100 (11) in the treatment of glaucoma.

  The invention relates to the use of a somatostatin receptor ligand of nonpeptide origin, e.g. of the general formula Ia or Ib ##STR1## or a pharmaceutically acceptable salt thereof, which has high and/or selective affinity to the somatostatin receptor protein designated SSTR4 and, for the preparation of a medicament for the treatment of a disease associated with an adverse condition in the retina and/or iris-ciliary body of a mammal. Such conditions are high intraocular pressure (IOP) and/or deep ocular infections. The diseases which may be treated are e.g. glaucoma, stromal keratitis, iritis, retinitis, cataract and conjunctivitis.
