A complex is provided for the treatment of neurogenic conditions having
the formula: ##STR00001## where R.sup.1 is ##STR00002## M 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.
