(R,S)-3,5-DHPG: Scientist Approved

Biological Data

Biological description

(R,S)-3,5-DHPG is a selective group I mGluR (mGluR1 / mGluR5) agonist.

(R,S)-3,5-DHPG stimulates phospholipase C (PLC) response and inhibits phospholipase D (PLD) response.

(R,S)-3,5-DHPG also induces LTD in the hippocampus.

The active enantiomer of DHPG: (S)-3,5-DHPG is also available.

Solubility & Handling

Storage instructions -20°C (desiccate). Protect from light.
Solubility overview Soluble in water (10mM)

The compound is of high purity, however it is air sensitive and light promoted oxidation may cause slight discoloration of the compound. Product performance should not be affected, and this decolourisation can be ignored.

It has been shown that this compound rapidly decomposes when dissolved in alkaline solution. We therefore recommend that you store the solid material at -20°C and protect from light. The compound should be stable for a least 6 months.

When possible, you should make up solutions and use immediately. If storage of solutions is required, you should aliquot out the solution into tightly sealed vials and store at -20°C and store these for up to one month. Allow the product to equilibrate to RT for at least one hour before opening and using.
