GAT229 is a positive allosteric modulator of cannabinoid receptor 1 (CB1) and the S-(-) enantiomer of the CB1 modulator GAT211. It does not activate the receptor on its own but enhances the binding and activity of CB agonists. GAT229 (1 μM) enhances the binding of the CB1 full agonist CP 55,940 to CHO cells expressing human recombinant CB1 (hCB1), as well as the activity of 2-arachidonoyl glycerol , arachidonoyl ethanolamide , and CP 55,940 in arrestin2 recruitment assays and increases ERK1/2 and PLCβ3 phosphorylation in HEK293 cells expressing hCB1. GAT229 (1 μM) enhances depolarization-induced suppression of excitation but does not inhibit excitatory postsynaptic currents (EPSCs) in murine autaptic hippocampal neurons. GAT229 (0.2%, topical) reduces intraocular pressure by 5.8 and 7.7 mm Hg after 6 and 12 hours, respectively, in a transgenic mouse model of ocular hypertension using nose, ear, eye mutation (nee) mice.

Methazolamide-d6 is intended for use as an internal standard for the quantification of methazolamide by GC- or LC-MS. Methazolamide is a carbonic anhydrase inhibitor. It reduces intraocular pressure and cerebrospinal fluid flow in a rat model of glaucoma. Methazolamide reduces electroshock-induced seizures in rats with an ED50 value of 19.2 mg kg. It also inhibits production of reactive oxygen species (ROS) in a primary cortical neuron (PCN) cellular model of subarachnoid hemorrhage (SAH) and reduces cerebral edema in a mouse model of SAH.3 Methazolamide is larvicidal, with a 50% larvicidal concentration (LC50) value of 724 ppm, but has no activity when administered in the diet to adult A. aegypti. Formulations containing methazolamide have been used in the treatment of glaucoma.

Latanoprost is an F-series prostaglandin (PG) analog which has been approved for use as an ocular hypotensive drug. Oxidation of the C-15 hydroxyl group without isopropyl ester hydrolysis produces 15-keto latanoprost. 15-keto Latanoprost is a potential metabolite of latanoprost when administered to animals. 15-keto Latanoprost is also one of the common minor impurities found in commercial preparations of the bulk drug compound. Although much less potent that the parent compound latanoprost, 15-keto latanoprost still retains the ability to produce a small but measurable decrease (1 mm Hg) in the intraocular pressure of normal cynomolgus monkeys when administered at a dose of 1 μg/eye. 15-keto Latanoprost is also a miotic in the normal cat eye, causing an 8 mm reduction in pupillary diameter at 5 μg/eye. Again, this is not as potent as many other F-type PGs; for example, PGF2α will produce this degree of miosis at a dose of less than 1 μg/eye. Products of β-oxidation account for most of the metabolites of latanoprost recovered in plasma and urine. However, 15-keto latanoprost is a minor metabolite, and one which could be enhanced in situations where β-oxidation is reduced.
