Publication number: 20210130285Abstract: A series of novel amides showing broad pharmaceutical activity. Compounds described herein are effective as anticonvulsants, chemical countermeasures, and analgesics. Such compounds also show, neuroprotective/neuroreparative effects and activity against spinal muscular atrophy. Such pharmaceutically active compounds show utility in the treatment of central nervous system (“CNS”) diseases and disorders, such as anxiety, depression, insomnia, migraine headaches, schizophrenia, neurodegenerative diseases (e.g., Parkinson's disease, Alzheimer's, ALS, and Huntington's disease) spasticity, and bipolar disorder. Furthermore, such compounds may additionally find utility as analgesics (e.g., for the treatment of chronic or neuropathic pain) and as neuroprotective agents useful in the treatment of stroke(s), and/or traumatic brain and/or spinal cord injuries.Type: ApplicationFiled: September 14, 2020Publication date: May 6, 2021Inventors: Amir Pesyan, Manuel F.

Patent number: 8420354Abstract: This application provides a process for preparing enantiomerically pure ?-D-dioxolane nucleosides. In particular, a new synthesis of (?)-DAPD, suitable for large scale development, is described. In one embodiment the invention provides a process for preparing a substantially pure ?-D- or ?-L-1,3-dioxolane nucleosides comprising a) preparing or obtaining an esterified 2,2-dialkoxy ethanol; b) cyclizing the esterified 2,2-dialkoxy ethanol with glycolic acid to obtain a 1,3-dioxolane lactone; c) resolving the 1,3-dioxolane lactone to obtain a substantially pure D- or L-lactone; d) selectively reducing and activating the D- or L-chiral lactone to obtain a substantially pure D- or L-1,3-dioxolane; e) coupling the D- or L-1,3-dioxolane to an activated and/or protected purine or pyrimidine base; and f) optionally purifying the nucleoside to obtain a substantially pure protected ?-D- or ?-L-1,3-dioxolane nucleoside.Type: GrantFiled: August 27, 2010Date of Patent: April 16, 2013Assignee: Emory UniversityInventors: Marcos Sznaidman, George R.
