12-hydroxylase

Ketoconazole (R-41400), a CYP3A4 inhibitor, is an imidazole anti-fungal agent.

Nurr1 agonist 12 (Compound 37) acts as an agonist of the nuclear receptor-related protein 1 (Nurr1), enhancing its transcriptional activity with an EC50 of 0.06 μM. It stimulates human response elements NBRE, NurRE, and DR5 with EC50 values of 0.07 μM, 0.027 μM, and 0.014 μM, respectively. Additionally, Nurr1 agonist 12 induces the expression of neurotrophic genes regulated by Nurr1, such as tyrosine hydroxylase (TH), SOD1/2, BDNF, Sestrin 3, and BIRC5 (Survivin). The compound also demonstrates neuroprotective effects against neurotoxicity caused by Paraquat.

(R)-Nepicastat HCl (RS-25560-198 HCl), the R-enantiomer of Nepicastat HCl, is a potent and selective inhibitor with IC50 of 25.1 nM and 18.3 nM for bovine and human dopamine-β-hydroxylase, with negligible affinity for twelve other enzymes and thirteen neurotransmitter receptors.

3-Allylphenol is an inhibitor of dopamine β-hydroxylase (DBH; Ki = 12 mM).

"Lysyl Hydroxylase 2-IN-1 (compound 12) is a selective inhibitor of lysyl hydroxylase 2 (LH2) with an IC50 of approximately 300 nM and demonstrates specificity for LH2 over LH1 and LH3 [1]."

Catalpalactone exhibits high antitermitic, and cytotoxic activities, it exhibits potent inhibitory effects on lipopolysaccharide-induced NO synthesis in RAW 264.7 cells , with IC50 values of 9.80 microM. Catalpalactone can inhibit dopamine biosynthesis by
