Light-Driven Molecular Nanomachines to Treat Pain and Neurodegenerative Disorders

This article was originally published in Start Up

Executive Summary

Imagine exposing a person to a particular wavelength of light and having a predetermined species of neuron shut down for as long as that light is on. Then a second light comes in to turn another neuron off, or turn one on, and so on. That's what an emerging group of researchers and a couple of start-up companies hope to be able to do, to potentially treat a variety of neurological conditions from chronic pain to seizures to spinal cord injury and even eye diseases.

Stroke Devices: Facing Challenges Head On

The International Stroke Conference, held in San Diego in February 2009, presented several device-based therapies and approaches that could offer improved outcomes for patients that suffer an acute ischemic stroke. The technologies discussed included mechanical thrombectomy devices, laser treatments, and combined therapy using ultrasound, microspheres, and thrombolytic drugs.

A New but Familiar Drug Target for Treating Memory Impairment

Inhibitors of histone deacetylases have been developed as cancer drugs, with only limited use because of toxicities. Now, a research team has shown that HDAC2 impairs memory and learning, suggesting that inhibitors targeting only that molecule could be used to treat neurodegenerative diseases. Buoyed by these new observations, companies with HDAC inhibitors in hand can screen their libraries specifically for activity against this newly-understood target.

New Approaches to Neuropathic Pain

In some ways, neuropathic pain seems an odd choice of focus for a small start-up. It comes in many forms and its mechanisms are poorly understood. Moreover, the size and strength of those with stakes in the pain market might be another reason for emerging companies to steer clear. Fortunately, they're not. The unmet need is huge: Only one in two patients actually get some relief from existing drugs, in part because their mechanisms of action are fairly generalized. There remains plenty to be done in identifying and understanding the precise mechanisms behind the various flavors of neuropathic pain. For those whocan figure out new approaches to pain or new uses in pain for failed or overlooked compounds -- the companies profiled in this issue are doing both -- there's a big reward at the end: Sales of neuropathic pain therapies in the seven major pharmaceutical markets reached nearly $5 billion in 2007.
