CDPPB is a novel, potent, selective and brain penetrant mGluR5 positive allosteric modulator. CDPPB has been shown to have positive therapeutic effects for cognitive deficits in schizophrenia and pathology in Huntington's disease, without stimulating to evoke seizures. CDPPB as well as other PAM's have potential to be nootropic drugs that enhance learning and cognitive processes, including with respect to ASD.

Solubility Data
| Solubility (In Vitro) | DMSO : ~100 mg/mL (~274.42 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 5 mg/mL (13.72 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 50.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.  (Please use freshly prepared in vivo formulations for optimal results.) |
