  • Patent number: 5268164
    Abstract: Polypeptides called receptor mediated permeabilizers (RMP) increase the permeability of the blood-brain barrier to molecules such as therapeutic agents or diagnostic agents. These receptor mediated permeabilizers are more efficacious than bradykinin in causing the blood-brain barrier to become more permeable. The permeabilizer A-7 or conformational analogues can be intravenously co-administered to a host together with molecules whose desired destination is the cerebrospinal fluid compartment of the brain. The permeabilizer A-7 or conformational analogues allow these molecules to penetrate the blood-brain barrier and arrive at this destination.

  • Patent number: 5206264
    Abstract: A method is disclosed for reducing cardiovascular damage caused by hypoxic or ischemic events such as heart attack and cardiac arrest. This method involves the administration of disulfiram, or a suitable salt or analog of disulfiram, to a mammal in need of such treatment. Disulfiram can inhibit enzymes such as xanthine oxidase which would otherwise generate oxygenated free radicals, which are highly reactive chemical compounds that non-specifically attack and damage essential molecules and cells. It can also chelate copper and iron, thereby suppressing lipid peroxidation and protecting cell membranes from destruction. It also generates metabolites such as tryptophol which reduce the rate of metabolic activity in neurons and affected tissue, which can be useful during cytotoxic events. This invention also discloses injectable formulations that rapidly release disulfiram into the circulating blood.

Several polysaccharides, including polymers of different size of .sym.1-4 linked D-mannuronic acid (poly-M and M-blocks), chitosan and cellulose oxidized in C-6 position C60XY) induce human monocytes to produce the cytokines. Preferably, the molecular weights of poly-M and chitosan are above 50,000 and 20,000 respectively. Pretreatment of the monocytes with IFN-.gamma. increases the cytokine production from monocytes stimulated with all polysaccharides tested. The subject polysaccharides worked in vivo and in vitro.The present invention has therapeutic utility as vaccine adjuvants and components. Therapeutic compositions comprising biologically active quantities of the compositions of the present invention may be employed to potentiate antibody production in response to vaccine antigens. Anti-tumor, anti-bacteriological, anti-fungal and anti-viral effects may be expected.

  • Patent number: 4985454
    Abstract: A process for the preparation of S- or R-carbazole derivatives of the general formula: ##STR1## in which R is an unsubstituted or substituted amino radical and pharmacologically acceptable salts, by either reacting R-(-)-epichlorohydrin (for the S-carbazole derivative); or reacting an S-epoxide derivative of the general formula: ##STR2## in which R.sub.1 is the residue of a substituted sulphonic acid derivative (for the R-carbazole derivative); with 4-hydroxycarbazole and then with ammonia or a substituted amine of the general formula RH, and recovering the compound or converting it to a pharmacologically acceptable salt.The new R-(+)- and S(-)-carbazole derivatives provided by the inventive process have unexpected beta blocking and vasodilatory properties and are useful in pharmaceutical compositions. R-(+)-carbazole derivatives are also useful for the treatment of glaucoma.
