TGR-63
Targeting Brain Plaque
Pathways in Alzheimer’s Disease
Designed to cross the blood–brain barrier, TGR-63 is being developed to support targeted therapeutic delivery in the brain.
What is
TGR-63?
TGR-63 is a synthetic, low molecular weight molecule, tailored designed to inhibit amyloid plaque aggregation in neuronal tissue by targeting previously unexplored binding sites. It has demonstrated brain blood barrier crossing and behavioral activity in preclinical studies.
How TGR-63 Works
TGR-63 is designed to interact with amyloid-beta peptides and may influence plaque aggregation dynamics through binding interactions. Computational studies suggest that TGR-63 may alter peptide structure and stability, supporting the formation of less aggregated states. These findings are supported by preclinical observations.
*TGR-63 has shown affinity for Aβ42 peptides in computational and preclinical studies, with evidence suggesting modulation of peptide structure and aggregation behavior.
Tracing the Origins:
The Development
of TGR-63 Compound
TGR-63 was licensed from the Jawaharlal Nehru Centre for Advanced Scientific Research in India and further developed by Prof. T. Govindaraju and his research group. Their work focused on a series of naphthalene monoimide compounds, evaluating their ability to inhibit amyloid-beta aggregation, assess cytotoxicity, and support neuronal function in preclinical studies.
Pre-clinical Studies: Detailed Scientific Results
TGR-63 reduces Aβ42 aggregation and enhances neuronal cell viability in a concentration-dependent manner*
With Aβ deposits decreased by 78% in the cortex and 85% in the hippocampus.*
In the Novel Object Recognition test, mice treated with TGR-63 showed increased exploration of a new object over a familiar one, indicating enhanced learning capacity.*
During the Morris Water Maze test, mice treated with TGR-63 exhibited improved spatial memory, with decreased latency in finding the target compared to the untreated group.*
In the Open Field Test, the evaluation of mice’s movement through an open arena provided measures of the total distance traveled, time spent in the center versus the periphery, and rearing behavior, indicating an improved response to the unfamiliar environment by mice treated with TGR-63.*
