WWL 154 is an serine hydrolase (SH) and fatty acid amide hydrolase FAAH-4 inhibitor.

Nitisinone-13C6is intended for use as an internal standard for the quantification of nitisinone by GC- or LC-MS. Nitisinone is an inhibitor of 4-hydroxyphenylpyruvate dioxygenase (HPPD), which converts 4-hydroxyphenylpyruvate (HPPA) to homogentisate in the tyrosine catabolic pathway.1Nitisinone increases urinary levels of HPPA and 4-hydroxyphenyllactate (HPLA) in rats when administered at a dose of 10 mg/kg. Nitisinone (3 mg/kg) prevents the neonatal lethality of fumarylacetoacetate hydrolase (FAH) deficiency in mice when administered to pregnant dams.2It exhibits hepatoprotective effects inFAH-/-mice, such as prevention of increases in plasma levels of aspartate serine aminotransferase (AST) and conjugated bilirubin, when administration is continued following birth at a dose of 1 mg/kg. Nitisinone (100 μg) decreases urinary excretion of homogentisate and increases urinary excretion of HPPA, HPLA, and 4-hydroxyphenylacetate in a mouse model of alkaptonuria induced by ethylnitrosourea.3Formulations containing nitisinone have been used in the treatment of hereditary tyrosinemia type 1 (HT-1). 1.Ellis, M.K., Whitfield, A.C., Gowans, L.A., et al.Inhibition of 4-hydroxyphenylpyruvate dioxygenase by 2-(2-nitro-4-trifluoromethylbenzoyl)-cyclohexane-1,3-dione and 2-(2-chloro-4-methanesulfonylbenzoyl)-cyclohexane-1,3-dioneToxicol.

WWL113 is a selective and orally active inhibitor of Ces3 (IC50: 120 nM) and Ces1f (IC50: 100 nM), exhibiting excellent selectivity for the 60-kDa serine hydrolase.

JJH260 is an N-hydroxy hydantoin carbamate that inhibits androgen-induced gene 1 (AIG1), an enzyme that hydrolyzes fatty acid esters of hydroxy fatty acids (FAHFAs). It blocks the hydrolysis of 9-PAHSA with an IC50 value of 0.57 μM. JJH260 also inhibits the novel FAHFA hydrolase androgen-dependent TFPI-regulating protein (ADTRP; IC50 = 8.5 μM), as well as the serine hydrolase ABHD6 and the lysophospholipases LYPLA1 and LYPLA2. JJH260 inhibits the FAHFA hydrolase activity of LNCaP and T cell lysates and intact cells.

JZP-MA-13 is a selective α β-hydrolase domain 6 (ABHD6) inhibitor with an IC50 value of 392 nM, and exhibits no inhibitory effects on monoacylglycerol lipase (MAGL), ABHD12, fatty acid amide hydrolase (FAAH), or other serine hydrolases. JZP-MA-13 also serves as a positron emission tomography (PET) ligand for in vivo imaging of ABHD6.

Tripeptidyl peptidase II (TPPII) is a serine peptidase of the subtilisin-type which removes tripeptides from the free NH2 terminus of oligopeptides. AAF-CMK is an irreversible inhibitor of TPPII commonly used at 10-100 μM. It does not significantly interfere with the chymotrypsin-like activity of the proteasome. AAF-CMK also inhibits bleomycin hydrolase and puromycin-sensitive aminopeptidase when used at 50 μM.

ABC44 is a potent inhibitor of serine hydrolase with IC50s of 0.1 μM and 6.5 μM for palmitoyl protein thioesterase 1 (PPT1) in situ and in vitro, respectively. ABC44 can be used to study late infantile neuron-like lipofuscinosis.

Fatty acid amide hydrolase (FAAH), an enzyme responsible for the hydrolysis and inactivation of fatty acid amides like anandamide and oleamide, has been identified as a target by the potent FAAH inhibitor PHOP. PHOP demonstrates remarkable inhibitory activity with K_i values as low as 0.094 nM for human FAAH and 0.2 nM for rat FAAH. Additionally, through a proteomics assay focusing on the serine hydrolase enzyme family, to which FAAH belongs, PHOP's selectivity was evaluated, presenting IC_50 values of 1.1 nM against FAAH, 1.4 nM against triacylglycerol hydrolase (TGH), and greater than 100 µM against an uncharacterized hydrolase (KIAA1363). This specificity profile of PHOP underscores its potential for yielding precise outcomes in studies involving complex biological systems.

ABC34 is an inactive control probe for JJH260 , the inhibitor of androgen-induced gene 1 (AIG1), an enzyme that hydrolyzes fatty acid esters of hydroxy fatty acids (FAHFAs). ABC34 demonstrates an IC50 value greater than 25 μM for the inhibition of 9-PAHSA but is more potent in blocking the serine hydrolase ABHD6 and the palmitoyl-protein hydrolase PPT1, which are both off-targets of JJH260.

Nitisinone (SC0735)(SC0735) is an enzyme 4-hydroxyphenylpyruvate dioxygenase inhibitor.
