Synthesis, in vitro/in vivo Antifungal Evaluation and Structure-Activity Relationship Study of 3(2H)-Pyridazinones

The synthesis, in vitro/in vivo antifungal evaluation and a structure-activity relationship (SAR) study of 3(2H)-pyridazinones was carried out. The results reported here may be helpful in the structural identification and understanding of the minimum structural requirements for these molecules acting as antifungal agents. In addition, the most active structure in this series was tested for its capacity of inhibiting Saccharomyces cerevisiae beta1,3-glucan synthase and chitin synthase, enzymes that catalyze the synthesis of the major polymers of the fungal cell wall.

Synthesis of ortho-functionalized 4-aminomethylpyridazines as substrate-like semicarbazide-sensitive amine oxidase inhibitors

A series of 4-aminomethylpyridazines and -pyridazin-3(2H)-ones (“diaza-benzylamines”), bearing alkylamino side chains in ortho position relative to the CH2NH2 unit, was synthesized by catalytic hydrogenation of the corresponding nitriles in strongly acidic medium. N-Benzyl protecting groups either at the pyridazinone ring nitrogen or at an exocyclic nitrogen were selectively removed hydrogenolytically or by treatment with a Lewis acid. The new compounds were tested in vitro for semicarbazide-sensitive amine oxidase (SSAO) inhibitory activity and 4-(aminomethyl)-N,N-diethylpyridazine-3,5-diamine (22) was found to be the most active representative.

Novel method for preparing fluorination reagent and its application to synthesis of fluoropyridazinones

4-Chloro-5-fluoro-2-aryl-3(2H)-pyridazinones were obtained by the fluorination of 4,5-dichloro-2-aryl-3(2H)-pyridazinones with ethylhexamethylenetetramine fluoride in excellent yields. The ethylhexamethylenetetramine fluoride was synthesized by the reaction of hydrofluoric acid with ethylhexamethylenetetramine hydroxide prepared from ethylhexamethylenetetramine bromide and alkali.

Synthesis and evaluation of nevirapine analogs to study the metabolic activation of nevirapine

Nevirapine (NVP) is widely used as a non-nucleoside reverse transcriptase inhibitor of HIV-1, however, it is associated with severe skin and liver injury. The mechanisms of these adverse reactions are not yet clear, but the metabolic activation of NVP is thought to be related to the injury process. Until now, several metabolic activation pathways of NVP have been reported. In this study, in order to identify the reactive metabolite of NVP mainly responsible for CYP inhibition and liver injury, we synthesized five NVP analogs designed to avoid the proposed bioactivation pathway and evaluated their metabolic stabilities, CYP3A4 time-dependent inhibitory activities, and cytotoxicity. As a result, only a pyrimidine analog of NVP, which could avoid the formation of a reactive epoxide intermediate, did not inhibit CYP3A4. Outside of this compound, the other synthesized compounds, which could avoid the generation of a reactive quinone-methide intermediate, inhibited CYP3A4 equal to or stronger than NVP. The pyrimidine analog of NVP did not induce cytotoxicity in HepG2 and transchromosomic HepG2 cells, expressing major four CYP enzymes and CYP oxidoreductase. These results indicated that the epoxide intermediate of NVP might play an important role in NVP-induced liver injury.

One-Pot Highly Regioselective Synthesis of Indole-Fused Pyridazino[4,5- b ][1,4]benzoxazepin-4(3 H)-ones by a Smiles Rearrangement

A simple and convenient synthesis of indole-fused pyridazino[4,5- b ][1,4]benzoxazepin-4(3 H)-ones is described. A range of 2-(1 H -indol-2-yl)phenols and 4,5-dichloropyridazin-3-ones are compatible with this reaction. A Smiles rearrangement is proposed as a key step in the highly regioselective construction of the products. The easy availability of the starting materials makes this an appealing method in organic synthesis.
