Alzheimer's Disease (AD) is a multifactorial and fatal neurodegenerative disorder affecting around 35 million people worldwide, which is characterized by decline of cholinergic function, deregulation of amyloid beta (Aβ) oligomers formation and Aβ fibril deposition. Multi-Target- Directed Ligands (MTDLs) have emerged as an original strategy for developing new therapeutic agents on AD. Multicomponent Reaction Read More

Tacrine was the first drug to display beneficial effects on cognitive impairment of Alzheimer Disease (AD) patients. Unfortunately, many treated patients displayed related hepatotoxicity, and hence this drug was withdrawn. Notwithstanding, recent efforts have been directed to design small tacrine analogues targeting the underlying pathogenic mechanisms of AD. In this context, we have developed a number of pyranotacrin Read More

Alzheimer's Disease (AD) once considered a rare disorder emerges as a major health concern in recent times. The disease pathogenesis is very complex and yet to be understood completely. However, “Amyloid Cascade” is the central event in disease pathogenesis. Several proteins of the amyloid cascade are currently being considered as potential targets for AD therapeutics discovery. Many potential compounds are in cli Read More

Tacrine was the first drug approved by FDA (US) for the treatment of Alzheimer's disease suffering patients. Nowadays, this agent has been withdrawn from the clinics due to secondary effects, which, most importantly, include hepatotoxicity. However, the research on new tacrine analogues devoid of these therapeutically undesirable effects, but benefiting of their high and well known positive cholinergic power, has Read More

In industrialized countries, Alzheimer's disease represents the most devastating neurodegenerative disorder in elderly people and the search for a disease modifying agent is still justified by this unmet need. Several possible targets have been explored to find an appropriate drug therapy, and in this review, dual inhibitors of beta secretase and glycogen synthase kinase 3, recently reported in literature, will be appraised. Applying Read More

Alzheimer's Disease (AD) is a fatal neurodegenerative disorder, having a complex aetiology with numerous possible drug targets. There are targets that have been known for years while more new targets and theories have also emerged. Beta amyloid and cholinesterases are the most significant biological targets for finding curative treatment of AD. The major class of drugs used for AD till now has been the Cholinester Read More
