3,3'-Difluorobenzaldazine
Based on 1 Customer Validation
3,3'-Difluorobenzaldazine (DFB) is a selective positive allosteric modulator of mGluR5. 3,3'-Difluorobenzaldazine potentiates 3- to 6-fold action for mGlu5 agonists (Glutamate, Quisqualate, and 3,5-Dihydroxyphenylglycine), with EC50s in the 2 to 5 μM range.

3,3'-Difluorobenzaldazine (DFB) causes a concentration-dependent potentiation of the response of human mGluR5 CHO cells to 300 nM glutamate in this assay. The maximal potentiation at this concentration of glutamate is approximately 3.1-fold, with an EC50 for potentiation of 2.6 μM. 3,3'-Difluorobenzaldazine causes similar potentiation of the responses of both human mGluR5 and rat mGluR5 CHO cells to glutamate, quisqualate, and DHPG with comparable potencies[1].
