General description

(±)-2-Amino-4-phosphonobutyric acid or DL-AP4 is a group III nonselective metabotropic glutamate receptor (mGluR) agonist. L-2-amino-4-phosphonobutyric acid (L-Ap4) displays close to 500-fold selectivity for group III mGluRs.

Application

(±)-2-Amino-4-phosphonobutyric acid may be used as a glutamic acid receptor blocker in perfusion solution in the eye tissue electroretinography studies.

Chronic neuropathic pain remains an unmet clinical problem because it is often resistant to conventional analgesics. Metabotropic glutamate receptors (mGluRs) are involved in nociceptive processing at the spinal level, but their functions in neuropathic pain are not fully known. In

To determine the influence of RIBEYE deletion and the resulting absence of synaptic ribbons on retinal light signaling by electroretinography. Full-field flash electroretinograms (ERGs) were recorded in RIBEYE knock-out (KO) and wild-type (WT) littermate mice under photopic and scotopic conditions

We propose that the end product of chromophore bleaching in rod photoreceptors, all-trans retinol, is part of a feedback loop that increases the sensitivity of the phototransduction cascade in rods. A previously described light-induced hypersensitivity in rods, termed adaptive potentiation
