ARN 077 is a selective N-acylethanolamine acid amidase (NAAA) inhibitor (IC50: 7 nM for human NAAA). ARN 077 significantly increases palmitoyl ethanolamine (PEA) levels within the CNS.
17-phenyl trinor Prostaglandin F2α N-ethyl amide (17-phenyl trinor PGF2α) is an F-series prostaglandin analog which has been approved for use as an ocular hypotensive drug, sold under the Allergan trade name 17-phenyl trinor PGF2α ethyl amide. Investigations in our lab have shown that 17-phenyl trinor PGF2α ethyl amide is converted by an amidase enzymatic activity in the human cornea to yield the corresponding free acid, with a conversion rate of about 25 μg cornea 24 hours. The free acid, 17-phenyl trinor PGF2α, is a potent FP receptor agonist. 15(R)-17-phenyl trinor PGF2α is the 15-epi, or unnatural isomer of this active free acid metabolite. It has much diminished FP receptor-mediated activity
17-Phenyl trinor Prostaglandin F2αdiethyl amide (17-phenyl trinor PGF2αdiethyl amide) is a Prostaglandin F2α(PGF2α) analog characterized by the substitution of the C-1 carboxyl group with an N-diethyl amide. Prostaglandin (PG) esters and N-ethyl amides have demonstrated ocular hypotensive properties, with N-ethyl amides introduced as alternative options for PG hypotensive prodrugs. Studies indicate that both bovine and human corneal tissues can convert N-ethyl amides of various PGs into their free acid forms at a rate of approximately 2.5 µg g corneal tissue hr. However, dialkyl amides like 17-phenyl trinor PGF2αdiethyl amide resist conversion by corneal amidase, showing no detectable transformation into free acids. This characteristic suggests their potential as valuable investigative tools for assessing the intrinsic intraocular hypotensive activities of PG amides.
