  • Publication number: 20150126611
    Abstract: 3,3-diphenyl-N-(1-phenylethyl) propan-1-amine (fendiline): as a new selective ligand of the sigma-1 receptors, with anti-apoptotic (cytoprotective) properties and prototypical anticancer activity. This invention concerns the prototypical profile of selective sigma-1 ligand and the putative therapeutical properties of the compound 3,3-diphenyl-N-(1-phenylethyl) propan-1-amine (DPPA) and its pharmaceutically acceptable salts, with cytoprotective activity, more specifically for neurons against the neurodegenerative diseases (e.g. Alzheimer's disease, Huntington's disease, Parkinson's disease) via their anti-apoptotic properties induced by their selective sigma-1 agonism. Concerning the cancer cells, DPPA exhibited pro-apoptotic properties associated with neuroprotective activity originating a prototypical anticancer profile consisting in synergistical association with the clinically used anticancer drugs with its analgesic and neuroprotective activities antagonizing the neuropathic pain induced by the later.

  • Publication number: 20100286446
    Abstract: The invention relates to a method of obtaining 3,3-diphenylpropylamines (I), wherein R1 is H, alkyl, haloalkyl or alkoxyalkyl, R2 is alkyl, alkoxy, halogen, NO2, CN, CHO, which may be free or protected, CH2OH or COOR6, and R3 and R4 are selected independently from H and alkyl or together with the nitrogen to which they are bound form a ring having 3 to 7 members. The inventive method consists in reacting a propylenephenylamine and a disubstituted aromatic hydrocarbon and, if necessary, separating the desired enantiomer or the mixture of enantiomers, and/or converting the compound (I) into a salt. Compounds (I) are muscarinic receptor antagonists which can be used in the treatment of urinary incontinence and other symptoms of urinary bladder hyperactivity. Said compounds include tolterodine.

  • Patent number: 7625681
    Abstract: There is provided an organic photoconductive material that can realize an electrophotographic photoreceptor which is not only excellent in charge transporting ability but also excellent in solubility in a solvent and compatibility with a resin and moreover, which is excellent in both electric properties and durability, and the organic photoconductive material that is useful also as a raw material compound for various types of functional materials. An asymmetric bis-hydroxyenamine compound represented by the following structural formula (1aa) is provided. The compound is allowed to be contained in a charge transporting layer or a surface protective layer of an electrophotographic photoreceptor. This leads realization of the electrophotographic photoreceptor which is excellent in electric properties and durability and can stably form an image of high quality being free of an image defect such as a black spot.
