Recent patents on CNS drug discovery

BACKGROUND: Owing to the increasing aged population globally, disorders and diseases of the CNS are anticipated to increase and profoundly impact the health care. As these neurodegenerative diseases (NDD) are complex, multifactorial and do not have identified etiological factors, unfortunately, drugs developed for the purpose have not met with the expected success. Hence, there has been a constant demand for the development of natural therapeutic adjuvants which are safe and possess the potential to attenuate multiple pathways.

The fruit of Terminalia chebula Retz has been used as a traditional medicine in Asia and contains tannic acid, chebulagic acid, chebulinic acid and corilagin. Extract from T. chebula seeds (TCE) has various biological functions. We observed the neuroprotective effects of TCE against ischemic damage in the hippocampal C1 region (CA1) of the gerbil that had received oral administrations of TCE (100 mg/kg) once a day for 7 days before the induction of transient cerebral ischemia.

The search for effective treatments that prevent oxidative stress associated with premature ageing and neurodegenerative diseases is an important area of neurochemical research. As age- and disease-related oxidative stress is frequently associated with mitochondrial dysfunction, amphiphilic antioxidant agents of high stability and selectivity that target these organelles can provide on-site protection.

In Roman mythology, Janus was the god of gates, doors, beginnings and endings. He was usually depicted with two faces looking in opposite directions. Janus was frequently used to symbolize change and transitions, such as the progression from past to future or from one viewpoint to another. 2,4-dinitrophenol (DNP) and other nitrophenols have long been known to be toxic at high concentrations (the 'bad' face of DNP), an effect that appears essentially related to interference with cellular energy metabolism due to uncoupling of mitochondrial oxidative phosphorylation.

Amyotrophic lateral sclerosis (ALS) is a devastating and fatal neurodegenerative disease of adults which preferentially attacks the neuromotor system. Riluzole has been used as the only approved treatment for amyotrophic lateral sclerosis since 1995, but its mechanism(s) of action in slowing the progression of this disease remain obscure. Searching PubMed for "riluzole" found 705 articles published between January 1996 and June 2009.

An increasing body of evidence indicates a role for oligomers of the amyloid-? peptide (A?) in the neurotoxicity of this peptide and the pathology of Alzheimer's disease (AD). Several neurotoxic oligomeric forms of A? have been noted ranging from the larger Amyloid ?-Derived Diffusible Ligands (ADDLs) to smaller trimers and dimers of A?. More recently a dodecameric form of A? with a 56 kDa molecular weight, denoted A?*56, was shown to cause memory impairment in AD model mice.

The burden of cognitive disorders is likely to increase over the coming years due to both increased longevity and altered risk factor patterns, arising from changes in lifestyle, healthcare and society. Vascular dementia with its underlying heterogeneous pathology, is a challenge for clinicians, and is frequently further aggravated by overlap with other neurodegenerative processes. Current Alzheimer's disease drugs have had limited clinical efficacy in treating vascular dementia and none have been approved by major regulatory authorities specifically for this disease.

ETHNOPHARMACOLOGICAL RELEVANCE: Eucommia ulmoides Oliv. Bark. (EUE), has commonly been used to fortify the muscles and lungs, lower blood pressure, prevent miscarriage, improve the tone of liver and kidneys, and promote longevity the traditional tonic medicines of Korea, China, and Japan. AIM OF THE STUDY: In this study, we investigated that the neuroprotective activities and possible mechanisms of EUE aqueous extract in hydrogen peroxide (H(2)O(2))-induced neuronal cell death in human SH-SY5Y neuroblastoma cells.

Parkinson's disease (PD) is a complex multifactorial disease marked by extensive neuropathology in the brain with selective yet prominent and progressive loss of mid-brain dopaminergic neurons. The etiological factors involved in the development of PD are still elusive, but oxidative stress arising when reactive oxygen species (ROS) exceed amounts required for normal redox signaling is considered one of the major factors. ROS cause oxidative damage to proteins, lipids, and DNA and are one of the most prominent factors related to neurodegeneration.

Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder characterized by the selective loss of motor neurons in the spinal cord, brain stem, and motor cortex. Mutations in superoxide dismutase (SOD1) are associated with familial ALS and lead to SOD1 protein misfolding and aggregation. Here we show that the molecular chaperone, HSJ1 (DNAJB2), mutations in which cause distal hereditary motor neuropathy, can reduce mutant SOD1 aggregation and improve motor neuron survival in mutant SOD1 models of ALS.
