Title:	Compounds and methods of prophylaxis and treatment regarding nicotinic receptor antagonists
Abstract:	It is an object of the present invention that the novel nicotinic receptor antagonists disclosed herein may be used in a broad array of clinical or medicinal facets. For example, it is a contemplated use of the present invention that the novel nicotinic receptor antagonists be used to inhibit the growth cycle of non-small cell lung cancer cells. Without being bound by theory, it is an object of the present invention that the nicotinic receptor antagonists disclosed herein are believed to possess reversible binding properties. Moreover, the compounds of the present invention are selective for 0.7 nAChR. For example, the compounds of the present invention are not believed to bind to 0.4 (32 nAChR neuromuscular receptors. It is also contemplated that the nicotinic receptor antagonists of the present invention will be used as a counter measure to treat exposure, or potential exposure, to a wide array of potential neurotoxins.

Application Number:	14/127,699
Patent Claims:	1. A method for the treatment of a disease or disorder characterized by the activation of an acetylcholine receptor pathway, comprising administering to the patient an effective amount of a .alpha.7 nicotinic acetylcholine receptor antagonist according to Formula I or Formula II in a free or pharmaceutically acceptable salt form, wherein said disease or disorder is selected from the group consisting of small-cell lung cancer, non-small cell lung cancer, organophosphorus nerve agent intoxication, human immunodeficiency virus (HIV) infection, acquired immune deficiency syndrome (AIDS), squamous cell carcinoma, adenocarcinoma, large cell carcinoma, pleura mesothelioma, solid tumor carcinoma, cognitive impairment, or a combination thereof, or wherein treatment is directed towards improving cognition, or smoking cessation, wherein Formula I is: ##STR00004## Wherein R.sub.1 is selected from a benzyl, phenethyl, 2-methoxyethyl, isobutyl, or cyclopentyl group; Wherein R.sub.2 is selected from a hydrogen or methyl group; Wherein R.sub.3 is selected from a chlorine, methoxyethyl, methyl, fluorine or cyclopentyl group; and Formula II is: ##STR00005## Wherein R.sub.1 is selected from a benzyl, methyl, or hydrogen group; Wherein R.sub.2 is selected from H or methyl; Wherein R.sub.3 is selected from a propyl, methyl, cyclopropyl, or 4-tolyl group; Wherein R.sub.4 is selected from a hydrogen, fluorine, chlorine, or furyl group. 2. The method of claim 1, wherein said disease or disorder is small cell lung cancer. 3. The method of claim 1 wherein said disease or disorder is non-small cell lung cancer. 4. The method of claim 1, wherein said disease or disorder is organophosphorus nerve agent intoxication. 5. The method of claim 1 wherein said disease or disorder is infection via the human immunodeficiency virus (HIV). 6. The method of claim 1, wherein said disease or disorder is acquired immune deficiency syndrome (AIDS). 7. The method of claim 1, wherein said disease or disorder is selected from squamous cell carcinoma, adenocarcinoma, large cell carcinoma, or pleura mesothelioma. 8. The method of claim 1 wherein said disease or disorder is a solid tumor carcinoma. 9. The method of claim 1, wherein a novel .alpha.7 nicotinic acetylcholine receptor antagonist of Formula I is administered simultaneously with a second treatment for cancer selected from the group consisting of: capecitabine, trastuzumab, pertuzumab, cisplatin and irinotecan. 10. The method of claim 1, wherein the disease or disorder is a cognitive impairment. 11. The method of claim 10, wherein the cognitive impairment is selected from the group consisting of impaired auditory processing and attention, impaired spatial organization, impaired verbal learning, impaired semantic and verbal memory, impaired executive functions, or Alzheimer's disease. 12. The method of claim 1, wherein the disease or disorder is Alzheimer's disease. 13. The method of claim 1, wherein said disease or disorder is cognitive impairment, and said cognitive impairment is a symptom of Alzheimer's disease. 14. The method of claim 1, wherein the treatment is directed toward smoking cessation in a patient. 15. The method of claim 1, wherein said disease or disorder is cognitive impairment, and said cognitive impairment is a symptom of psychosis. 16. The method claim 1, wherein the treatment is directed toward improving cognition.
