NGB 2904
Chemical Name: N-[4-[4-(2,3-Dichlorophenyl)-1-piperazinyl]butyl]-9H-fl uorene-2-carboxamide

Biological Activity:

Potent and selective dopamine D3 receptor antagonist (Ki values are 1.4, 217, 223, 642, > 5000, > 10000 and > 10000 nM for D3, D2, 5-HT2, α1, D4, D1 and D5 receptors respectively). Potently antagonises quinpirole-stimulated mitogenesis (IC50 = 6.8 nM). Attenuates cocaine's rewarding effects and inhibits relapse to drug-seeking behaviour.

    Purity To Rely On
    When choosing reagents for an experiment, the prime consideration is often to obtain the highest quality products available.

    Unlike other suppliers, our in-house QC team carry out multiple analytical tests to thoroughly assess the purity of our reagents before they are offered for sale.

    This accurate purity data is available on a batch-specific basis for every product via our website. At Tocris we work hard to ensure that we always supply to the highest possible standards of purity.
