Indoline Compounds for the Treatment of Spinal Muscular Atrophy (SMA) and Other Diseases

Posted Oct 31 2008 5:00pm

Description of Invention:
With the goal to treat SMA in patients, several indoline compounds were made and tested for activity. Tests in cells demonstrate that these drugs increased the levels of active SMN protein. This is encouraging since low levels of this protein appears to be the cause of neuronal death that leads to SMA. This class of compounds appears to operate via read-through of a non-sense stop-codon to produce full length, functional protein in SMA models. This mechanism may have utility in several other neurological disorders, including cystic fibroses and Duchene’s Muscular Dystrophy.

In addition, these compounds have also been shown to increase the concentration of a glutamate transporter protein in cells, which acts to recover glutamate back into neurons after release. Since the toxic effect of unrecovered excess glutamate is observed in many notorious neurological conditions, these compounds have potential for prevention or treatment.

  • Treatment of SMA in infants and children
  • Treat genetic-based diseases that result from a premature stop of protein synthesis such as muscular dystrophy and cystic fibrosis
  • Treating or preventing neurological diseases presenting glutamate toxicity like multiple sclerosis, Parkinson’s, Alzheimer’s, amyotrophic lateral sclerosis (ALS), or others
