A complex is provided for the treatment of neurogenic conditions having the formula:where R1 isM is a metal ion Ca(II), Mg(II), Cu(II) or Ni(II); n is an integer 1 or 2; R is BBB peptide, transferrin, membrane transporter peptide, TAT peptide, bradykinin, beta-endorphin, bombesin, calcitonin, cholecystokinin, an enkephalin, dynorphin, insulin, gastrin, substance P, neurotensin, glucagon, secretin, somatostatin, motilin, vasopressin, oxytocin, prolactin, thyrotropin, an angiotensin, galanin, neuropeptide Y, thyrotropin-releasing hormone, gonadotropnin-releasing hormone, growth hormone-releasing hormone, luteinizing hormone, vasoactive intestinal peptidegluconate, L-lactate, L-leucine, L-tryptophan, and L-glutamate; and R is coupled to M through a carboxylate moiety. Magnesium(II) represents the preferred metal ion as magnesium is known to have neuroprotective effects. The metal ion is in part chelated by a non-steroidal anti-inflammatory drug that does not inhibit platelet activity and includes salicylate and ibuprofenate. The complex also includes a ligand operative in transport across the blood brain barrier. A process for making an inventive complex includes the stoichiometric addition of ligands containing carboxylate groups to a solution of the metal ion. In instances where the metal ion is magnesium(II), a stoichiometric ratio of 1:1:1 is found between the non-steroidal anti-inflammatory ligand:magnesium(II):transporter ligand.

Disclosed are peptide agents and uses thereof that are analogs of biologically active peptides such as somatostatin and bombesin. The compounds of the invention have the general formula X-Y-Z-Q, where X is a cytotoxic agent, therapeutic agent, detectable label or chelating group, and Q is a biologically active peptide. In peptide agents of the invention Y is optionally a hydrophilic polymer or peptide, and Z is a linking peptide bonded to Q at the amino terminus of Q, having two, three, four, or five, amino acid residues selected to link X to Q, while retaining the biological activity of Q. Methods of using these peptide agents in the diagnosis and treatment of diseases are also disclosed.

The invention is directed to novel Lutetium-177-labeled bombesin analogs for treatment of tumor by radiotherapy.

[Problems] To provide a pharmaceutical, in particular a compound which can be used as a therapeutic agent for irritable bowel syndrome (IBS).[Means for Solving Problems] It was found that a tetrahydroisoquinolin-1-one derivative having an amide group at the 4-position or a pharmaceutically acceptable salt thereof has an excellent bombesin 2 (BB2) receptor antagonistic action. It is also found that the tetrahydroisoquinolin-1-one derivative is highly effective on bowel movement disorders. From the above, the tetrahydroisoquinolin-1-one derivative of the present invention is useful as a therapeutic agent for diseases associated with a BB2 receptor, in particular IBS.
