Ro 41-1049
Ro 41-1049 is a highly selective, reversible MAO-A inhibitor. Ro 41-1049 effectively blocks the Quinpirole (HY-B1752)-induced increase in dopamine D2-like receptor density in the nucleus accumbens and alters the pattern of behavioral sensitization, shifting animals' responses from enhanced motor activity to immobile self-directed gaping behavior. Tritium-labeled Ro 41-1049 serves as a high-affinity radioligand, enabling accurate mapping of the distribution and abundance of MAO-A in the central nervous system, peripheral organs, and human brain via quantitative enzyme autoradiography. Ro 41-1049 can be used for basic research on depression and other related diseases.

Ro 41-1049 (10 μM; 4 hrs) inhibits a portion of in vitro [3H]quinpirole binding to dopamine D2-like receptors in nucleus accumbens and striatum tissue homogenates, though this inhibitory effect is not modulated by prior in vivo quinpirole or Ro 41-1049 treatments[1].
Tritiated Ro 41-1049 (1-150 nM; 60 min) binds to MAO-A in rat cerebral cortex sections with high affinity (Kd = 10.7 nM) and a maximum binding capacity of 7.38 pmol/mg protein, with consistent high-affinity binding across rat brain regions[2].

Animal Model:Long-Evans (male, 200-230 g at study start)[1]
-
Dosage:1 mg/kg
-
Administration:s.c.; 90 minutes prior to each quinpirole injection; twice weekly for 8 pairs of injections
-
Result:Increased total mouthing after the 8th injection to 7-times higher than in saline control rats.
Reduced [3H]spiperone binding in the nucleus accumbens by 38% compared to quinpirole-sensitized rats without Ro 41-1049 pre-treatment.
Prevented the 32% increase in [3H]quinpirole and [3H]spiperone binding observed in the nucleus accumbens of quinpirole-sensitized rats, with receptor binding levels matching saline controls.
Showed no alterations in dopamine D2-like receptor binding, percentage of receptors in the high affinity state, or percentage of MAO inhibitor-inhibitable [3H]quinpirole binding in the striatum.
Resulted in distance traveled not different from saline controls.
