MSOP Chemical Properties, Uses, Production

Uses

MSOP is a selective antagonist of group III mGlu receptors.

Biological Activity

MSOP is a selective group III metabotropic glutamate receptor antagonist. Displays an apparent KD of 51 μM for the L-AP4-sensitive presynaptic mGluR on primary afferent terminals in spinal cord compared to > 700 μM for the (1S,3S)-ACPD-sensitive presynaptic mGlu in the same system. Has no activity on postsynaptic mGlu receptors or on ionotropic glutamate receptors on neonatal rat motoneurons.

in vivo

It is found that TBOA-induced antinociceptive effects are significantly blocked by intrathecal co-administration of MSOP (second phase of formalin model: F3,16=30.96, P<0.001; CFA model: F3,16=30.77, P<0.001). As expected, intrathecal TBOA (10 μg) reduces the number of formalin-induced flinches and shakes by 47% of the value in the saline-treated group in the second phase (P<0.001) and blocked the CFA-induced decrease in ipsilateral paw withdrawal latency by 60% of the value in the saline-treated group (P=0.01). The number of formalin-induced flinches in the second phase in the group treated with MSOP and TBOA is increased by 56% (P=0.04) of the value in the TBOA-treated group. CFA-induced paw withdrawal latency in the group treated with MSOP and TBOA is decreased by 86% (P=0.03) of the value in the TBOA-treated group[2].
