Chloramphenicol amine peptide derivatives containing tripeptide fragments of regulatory “stop peptides”–MRL, IRA, IWP–were synthesized. The ability of the compounds to form ribosomal complexes was studied by displacement of the fluorescent erythromycin analog from its complex with E. coli ribosomes. It was found that peptide chloramphenicol analogs are able(More)
Using a method of static simulation, a series of erythromycin A analogs was designed with aldehyde functions introduced instead of one of the methyl substituents in the 3′-N-position of the antibiotic that was potentially capable of forming a covalent bond with an amino group of one of the nucleotide residues of the 23S rRNA in the ribosomal exit tunnel.(More)
Novel fluorescent derivatives of macrolide antibiotics related to tylosin bearing rhodamine, fluorescein, Alexa Fluor 488, BODIPY FL, and nitrobenzoxadiazole (NBD) residues were synthesized. The formation of complexes of these compounds with 70S E. coli ribosomes was studied by measuring the fluorescence polarization depending on the ribosome amount at(More)
Fenotropil and its structural analog--compound RGPU-95 to a greater extent reduce the severity of anxious and depressive behavior in male rats than in females. On expression of the anxiolytic compound RGPU-95 significantly exceeds Fenotropil, but inferior to Diazepam; of antidepressant activity--comparable to Melipramin and exceeds Fenotropil.
