Abstract:
The biogenic amines spermine, spermidine, and putrescine are essential factors of cell growth and differentiation. To inhibit pyridoxal-5'-phosphate dependent ornithine decarboxylase and pyruvate dependent S-adenosylmethionine decarboxylase, key enzymes of polyamine biosynthesis, a system of substrate-like O-substituted hydroxylamines is suggested. The best of these compounds were active at nanomolar concentrations. High potency and specificity of this type of inhibitors are discussed in terms of structural similarity of E-I and E-S complexes.

Preparation of Amines: Alkylation of Ammonia and Amines
Each alkylation step makes the nitrogen center more nucleophilic, which triggers successive alkylations until a quaternary ammonium salt is formed. Considering...
Preparation of 1° Amines: Azide Synthesis
Azide ions act as good nucleophiles and react with unhindered alkyl halides to form alkyl azides. Alkyl azides do not participate in further nucleophilic substitution reactions, thereby eliminating the chances of polyalkylated products. Alkyl azides are reduced by hydride-based reducing agents, like lithium aluminum...

Indirect-Acting Cholinergic Agonists: Mechanism of Action
Reversible inhibitors like edrophonium bind to a specific part of the enzyme called the anionic catalytic site. They form noncovalent bonds, which means they are not strongly attached to the enzyme. This creates a temporary and less stable enzyme–inhibitor complex, leading to...
