CGP-7930 was the first positive allosteric modulator of GABAB receptors described in literature.[1][2][3][4] CGP7930 is also a GABAA receptor positive allosteric modulator and a blocker of Potassium channels.[5]
CGP7930 was developed in Novartis and has been used extensively for scientific research. It has anxiolytic effects in animal studies,[6][7] and has a synergistic effect with GABAB agonists such as baclofen and GHB,[8][9] as well as reducing self-administration of alcoholic drinks and cocaine.[10][11]

Synthesis
[edit | edit source]The chemical synthesis has been described:[13] Starting material:[14] Product of first step:[15][16]
2,6-Di-tert-butylphenol is treated with formaldehyde, base and methanol to give [87-97-8] (2). Base catalyzed reaction with isobutaldehyde gives CGP-13501 (3). Hydride reduction of the aldehyde gives the primary alcohol.
According to Krysin (Russia), 2,6-Di-tert-butylphenol is reacted with Neopentyl glycol with lye in an autoclave. Although 1 step reaction, yield was quoted as merely 15%.[17]
