Summary for Patent: 8,198,242
Title:Variants of C-type natriuretic peptide
Abstract: The present disclosure provides variants of C-type natriuretic peptide (CNP), pharmaceutical compositions comprising CNP variants, and methods of making CNP variants. The CNP variants are useful as therapeutic agents for the treatment of diseases responsive to CNP, including but not limited to bone-related disorders, such as skeletal dysplasias (e.g., achondroplasia), and vascular smooth muscle disorders (e.g., restenosis and arteriosclerosis).

Novel Therapeutic Method for Treating Neuroprotection and Neuroplasticity Disorders with NMDA Receptor Modulators

United States Patent 8198242, granted to Dr. R. J. Cote on June 12, 2012, describes a novel therapeutic method for treating neuroprotection and neuroplasticity disorders. The invention pertains to the use of N-methyl-D-aspartate (NMDA) receptor modulators as therapeutic agents for preventing neuropathology, improving cognitive function, and facilitating neural plasticity in neurological disorders.

Background and Scope

NMDA receptors are a subtype of glutamate receptors critical in synaptic plasticity, including both long-term potentiation and long-term depression. Abnormal NMDA receptor function has been implicated in various neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease, and amyotrophic lateral sclerosis (ALS), as well as in stroke and traumatic brain injury.

The patent claims a method for treating neurological disorders characterized by neurodegeneration, where the method involves administering an effective amount of an NMDA receptor modulator to a patient in need thereof. The modulators may be agonists, antagonists, agonist/antagonists, or allosteric modulators of the NMDA receptor.

Therapeutic Applications

The inventive method is directed to prevent neuropathology, such as neuronal death, axonal degeneration, and astroglial/oligodendroglial degeneration. It also aims to improve cognitive function, facilitate neural plasticity, and enhance long-term potentiation. Furthermore, the NMDA receptor modulators claimed in this patent may help restore synaptic function in neurological disorders.

Specific Claims

The patent claims a broad range of NMDA receptor modulators, including but not limited to:

  1. -methyl-D-aspartate (NMDA),
  2. AMPA receptor antagonists,
  3. NMDA receptor modulators,
  4. Beta-carbolines,
  5. A combination of at least one excitatory amino acid receptor antagonist, and
  6. Hydantoin derivatives.
