Acetylcholine Chloride is the chloride salt form of acetylcholine, a synthetic, quaternary amino alcohol with cholinergic properties. Acetylcholine chloride (Pilofrin) mimics the parasympathomimetic effect of the endogenous compound acetylcholine. Administered as an ophthalmic solution, this drug stimulates the cholinoceptors in the sphincter muscle of the iris, causing the pupil to constrict.

Bimatoprost is the Allergan trade name for 17-phenyl trinor prostaglandin F2α ethyl amide (17-phenyl trinor PGF2α ethyl amide), an F-series PG analog which has been approved for use as an ocular hypotensive drug. Oxidation of the C-15 hydroxyl group produces 15-keto-17-phenyl trinor PGF2α ethyl amide. 15-keto-17-phenyl trinor PGF2α ethyl amide is a potential metabolite of 17-phenyl trinor PGF2α ethyl amide when 17-phenyl trinor PGF2α ethyl amide is administered to intact animals. No pharmacological studies on 15-keto-17-phenyl trinor PGF2α ethyl amide have been reported.

PGBx is a mixture of oligomers of PGB1 with a molecular weight of 1,000-1,500. It has antioxidant and free radical trapping activity that was first studied in isolated mitochondria.1 PGBx has anti-inflammatory and cytoprotective activity which may be attributed to inhibition of the 14 kDa sPLA2.2,3 At a dose of 1 mg/kg, PGBx significantly reduces the incidence of ulcers in rats.2References1.

Isoprostanes are produced by the non-enzymatic, free radical peroxidation of phospholipid-esterified arachidonic acid. They have been used as biomarkers of oxidative stress, but they also have been found to have potent biological activity. ent-8-iso-15(S)-Prostaglandin F2α (ent-8-iso-15(S)-PGF2α) is a potent vasoconstrictor of porcine retinal and brain microvessels with EC50 values of 15 and 24 nM, respectively. This isoprostane is about ten-fold more potent than 8-iso-PGF2α in a whole blood platelet aggregation inhibition assay.

Enzymatically-derived prostaglandin E2 (PGE2) is an optically pure compound whereas PGE2 derived from the free radical-catalyzed peroxidation of arachidonate is a racemic mixture. Ent-PGE2 is the opposite enantiomer of PGE2. Significant amounts of racemic PGE2 (rac-PGE2) are generated in vitro and in vivo in settings of oxidative stress via the isoprostane pathway. A proposed mechanism for the formation of rac-PGE2 involves the base catalyzed equilibration from 15-E2t-isoprostane (8-iso-PGE2), generated from the 15-H2t-isoprostane endoperoxide.
