Biological Activity
Anle138b is an aggregation-modulating research compound studied in α-synucleinopathies. Published mouse data connect reduced oligomer burden with neuronal and motor outcomes. Anle138b was supplied in chow at 0.6 g/kg food. This concentration is not a dose per kilogram of animal body weight.
In Vitro
No separate compound-specific cell or biochemical result is available from the sources summarized here.
In Vivo
| Endpoint | Model / conditions / source | Reported result |
|---|---|---|
| Study design | PLP-α-syn transgenic mouse model of multiple system atrophy; treatment from 2 months of age for 5 months. [1], Methods | Anle138b was supplied in chow at 0.6 g/kg food. This concentration is not a dose per kilogram of animal body weight. |
| Motor and neuronal outcomes | Anle138b monotherapy, n=12; vehicle, n=10. [1], Results | Improved gait abnormalities and preserved nigral dopaminergic neurons compared with vehicle. |
| Brain pathology | α-Synuclein oligomer and microglial measurements in treated mice. [1] | Reduced oligomer burden was accompanied by decreased microglial activation. |
| Combination comparison | Anle138b combined with PD03 immunotherapy; separate treatment arm. [1] | Brain IgG binding was lower than with PD03 alone. The combination should not be described as uniformly superior to monotherapy. |
Interpretation
The monotherapy findings and immunotherapy combination are separate comparisons; combination treatment was not uniformly superior.
