Synthesis and biological evaluation of novel 1,2,3-benzotriazin-4-one derivatives as leukotriene A 4 hydrolase aminopeptidase inhibitors
摘要:
A series of novel 1,2,3-benzotriazin-4-one derivatives were designed, synthesized and their inhibitory activities against leukotriene A(4) hydrolase aminopeptidase in vitro were evaluated. Many compounds showed moderate to good activities at the concentration of 10 mu mol/L. Among them, compound IV-16 exhibited the highest inhibitory activity up to 80.6% with an IC50 of 1.30 +/- 0.20 mu mol/L. The compound IV-16 was also tested the proliferation inhibitory activities in THP1 human AML cell line and its binding model with LTA(4)H enzyme by molecular docking was studied. It indicated that 1,2,3-benzotriazin-4-one was a promising scaffold for further study. The relationship between structure and inhibitory activity was also preliminarily discussed.

A mild and effective one-pot synthesis of 1,2,3-benzotriazin-4(3H)-ones and benzothiatriazine-1,1(2H)-dioxide analogues has been developed. The method involves the diazotisation and subsequent cyclisation of 2-aminobenzamides and 2-aminobenzenesulfonamides via stable diazonium salts, prepared using a polymer-supported nitrite reagent and p-tosic acid. The transformation was compatible with a wide range

A novel oxidative rearrangement of 3-aminoindazoles is reported, enabling the production of diverse functionalized 1,2,3-benzotriazine-4(3H)-ones in good yields at room temperature. The key success of this unprecedented transformation of 3-aminoindazoles is the use of water as cosolvent, which could facilitate the halogen-induced ring expansion of 3-aminoindazoles under oxidative conditions.
A series of novel 1,2,3-benzotriazin-4-one derivatives were synthesized by the reaction of 3-bromoalkyl-1,2,3-benzotriazin-4-ones with potassium salt of 2-cyanoimino-4-oxothiazolidine in the presence of potassiumiodide. Nematicidal assays in vivo showed that some of them exhibited good control efficacy against the cucumber root-knot nematode disease caused by Meloidogyne incognita, up to 100% at the
