  • Patent number: 8426463
    Abstract: The present invention pertains generally to the field of coolants and medical therapy. More particularly, the present invention relates to certain anti-nociceptive agents, such as [((1R,2S,5R)-2-isopropyl-5-methyl-cyclohexanecarbonyl)-amino]-acetic acid isopropyl ester, that are potent and long-acting and selectively cooling for non-keratinized epithelial tissues as compared to keratinized epithelial tissues, and are useful, for example, for the treatment of (e.g., the alleviation of symptoms of; the amelioration of) sensory discomfort of non-keratinized stratified epithelial (NKSE) tissue; and so for treatment of: sensory discomfort of an ocular surface, an eyelid, a margin of an eyelid, an anterior part of an eyeball, a conjunctiva, a lachrymal system, a pre-corneal film, or a cornea, a lining of the oral cavity, an internal portion of the lips, a pharyngeal surface, an esophageal surface, or an anogenital surface; eye discomfort, e.g.

  • Publication number: 20120053152
    Abstract: Short-chain 2- to 3-carbon alcohols are used as solvents for cooling agents in the preparation of topical therapeutic and cosmetic formulations. Some of these alcohols, especially ethanol, inhibit the ability of the cooling agent to activate its target receptor. In one embodiment of this invention, (R)-1,2-propanediol is used as an alcoholic solvent for the topical delivery of cooling agents to biological surfaces. This propanediol enantiomer has a minimum inhibitory effect on cooling with respect to standard 2- to 3-carbon alcoholic solvents, and functions to substantially protect the agent's cooling activity from inhibition when in the presence of a short-chain alcohol.

  • Patent number: 7417048
    Abstract: Novel peripheral antinociceptive compounds are disclosed having a pharmacophore unit that target small-diameter nerve fibers that transmit signals of pain and discomfort from the soma and viscera. By acting on this target, the pharmacophore unit obtunds pain and diminishes hyper-reflexia from organs such as the skin, the respiratory tract, the corpus, the lower urinary tract, and the bowel. The pharmacophore unit is coupled to substituents that facilitate delivery of the pharmacophore to its target.

  • Patent number: 7169377
    Abstract: One embodiment of the invention is a composition that comprises a radioactive [18F], [123I], [125I], or [131I]-N-radiohaloaryl-alkylcarboxamide molecule. The composition binds to the transient receptor potential-M8 (TRP-M8) receptor of cells. The TRP-M8 receptor is selectively expressed in sensory neurons and in malignant tissues such as prostate cancer cells. The [18F], [123I], [125I], or [131I]-N-radiohaloaryl-alkylcarboxamide ligand may be used for radioreceptor binding studies, for diagnostic studies, and for radiotherapy of cancerous tissues. Affinity of the [125I] or [131I]-N-radiohaloaryl-alkylcarboxamide ligand for the TRP-M8 receptor confers selectivity and specificity in delivering lethal radiation to the diseased cells.

  • Patent number: 6953779
    Abstract: The clinical outcome of disseminated melanoma is grim. Small molecular weight antagonists (preferably about seven amino acid residues) specific for MCR on melanoma cells are provided for the therapy of melanoma as well as in other conditions where modulation of MCR is of clinical significance. A particularly preferred antagonist is p-anisoyl-[D-Arg6,9, D-Lys11, D-Leu12] dynorphin A(6-12)-NH2, which is an excellent antagonist of the MCR-1 receptor.

  • Patent number: 6803359
    Abstract: The glutamic acid residue of corticotropin-releasing hormone analogs have had the position 20 amino acid residue replaced with a D-amino acid moiety. The resulting CRH analogs do not significantly lower blood pressure but have anti-proliferative actions in cell culture and inhibit experimental cancer growth in animals (mice and rats). Novel applications of such analogs are described, such as to inhibit abnormal cell proliferation for conditions such as cancer, including melanoma, and for inflammatory dermatoses, such as psoriasis.
