Proparacaine
Based on 3 publication(s) in Google Scholar
Proparacaine (Proxymetacaine) is a local anesthetic. Proparacaine blocks voltage-gated sodium channels on neuronal cell membranes, thereby inhibiting signal conduction and nociceptive signal transmission. Proparacaine blocks nociceptive signals in the eye and induces ocular muscle relaxation to reduce eye movement during surgery. Proparacaine is used in research related to cataracts.

Activité biologique
Proparacaine competitively inhibits the activity of 6-phosphogluconate dehydrogenase (6PGD) purified from human erythrocytes, with an IC50 of 601.60 μM and a Ki of 811.50 μM[1].
Proparacaine non-competitively inhibits the activity of glutathione reductase (GR) purified from human erythrocytes, with an IC50 of 686.90 μM and a Ki of 1,654.00 μM[1].
Proparacaine alters the actin cytoskeleton of corneal epithelial cells[2].

Animal Model:Sprague-Dawley (male, 205-255 g)[3]
-
Dosage:0.20, 0.44, 0.59, 1.17, and 2.92 μmol/kg
-
Administration:s.c.; single injection; i.p. (single injection, no effect)
-
Result:Produced dose-dependent cutaneous antinociception.
Induced 46% maximal possible effect (% MPE) of nociceptive block at ED50 dose.
Induced 100% MPE (complete nociceptive block in all 8 rats) when coadministered at 1/2 ED50 with dopamine 1/2 ED50.
Showed synergistic antinociceptive interaction with dopamine via isobolographic analysis: experimental ED50 of the combination (14.0 μmol/kg, 95% CI 12.5-15.6) was significantly lower than theoretical additive ED50.
Produced no cutaneous antinociceptive effects when administered i.p. at 2.92 μmol/kg alone or coadministered with dopamine at 1/2 ED50.
