CDPPB is a selective, orally active and brain-penetrant mGluR5 allosteric modulator. CDPPB increases AKT and ERK1/2 activation and augments the BDNF mRNA. CDPPB inhibits caspase-3 activation and mitochondrial dysfunction. CDPPB improves cognitive impairment, depression, and Huntington's disease.

Animal Model:

Male Sprague-Dawley rats (250–300 g at the time of surgery, age not specified in this context for this part) with olfactory bulbectomy^[5]
Dosage:

2.5 or 5 mg/kg, dissolved in 0.5% methylcellulose
Administration:

Intraperitoneal injection (i.p.), once daily for 14 days
Result:

Reversed the cognitive impairment in the passive avoidance test at 5 mg/kg.
Partially abolished the lesion-induced increase in total eNOS protein in the prefrontal cortex.
Reversed the lesion - induced changes in both total eNOS protein and D/M ratio in the striatum.
Had no impact on the lesion - induced decrease in total nNOS protein in the hippocampus but counteracted the lesion - induced increase in total nNOS protein in the striatum.
Decreased DDAH1 expression in the hippocampus and striatum of lesioned animals and reduced RAGEs expression in the hippocampi of sham animals and in the striata of OB animals.

Stock Solution Working Solution

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocol 1

Add each solvent one by one: 10% DMSO 90% Corn Oil

Solubility: ≥ 5 mg/mL (13.72 mM); Clear solution

This protocol yields a clear solution of ≥ 5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
