Dafadine-A is a selective inhibitor of DAF-9 cytochrome P450 in the nematode Caenorhabditis elegans. Dafadine-A inhibits the mammalian ortholog of DAF-9 (CYP27A1). Dafadine-A does not inhibits DAF-12 and sterol- and oxysterol-metabolizing P450s[1]. | [Definition]
ChEBI: Dafadine A is an N-acylpiperidine obtained by formal condensation of the carboxy group of 5-[(2,6-dimethylphenoxy)methyl]-1,2-oxazole-3-carboxylic acid with the secondary amino group of 4-(pyridin-4-yl)piperidine. It has a role as a P450 inhibitor and a geroprotector. It is a member of pyridines, a N-acylpiperidine, a member of isoxazoles, an aromatic ether and an aromatic amide. | [Biological Activity]
Dafadine A is a selective inhibitor of C. elegans DAF-9 cytochrome P450a key regulator of dauer formationdevelopmental timing and longevity. C. elegans has four life stages. In harsh environmental conditionsnematodes can convert to the L3 stageknown as the ""non-aging"" dauer stagein which development ceases until improved conditions are sensed. Dafadine A can induce dauer formation and increased longevity in wild-type worms raised in nonstressful conditions. Dafadine A is the only inhibitor known to robustly inhibit DAF-9 in wild-type worms. It does not inhibit DAF-12 activity. Dafadine is active in mammalian systemsinhibiting CYP27A1the mammalian functional ortholog of DAF-9 th at oxidizes 4-cholesten-3-one to make 26-hydroxy-4-cholesten-3-one and Δ4-dafachronic acidwithout inhibiting other sterol- and oxysterol-metabolizing P450s such as CYP7A1 or CYP7B1. | [References]
