Reactions of 1,5-diaryl-4-heteroyl-3-hydroxy-3-pyrrolin-2-ones with arylamines and butylamine
摘要:
1,5-Diaryl-4-[2-thienoyl(furanoyl)]-3-hydroxy-3-pyrrolin-2-ones reacted with aromatic amines to form arylamino-3-pyrrolin-2-ones. Reactions with butylamine occurred via intermediate salt formation followed by their transformation into 3-butylamino-3-pyrrolin-2-ones at heating.
Reactions of 5-aryl-4-(hetaren-2-ylcarbonyl)-3-hydroxy-1-(1,3-thiazol-2-yl)-2,5-dihydro-1H-pyrrol-2-ones with hydrazine, phenylhydrazine, and hydroxylamine
摘要:
Three-component condensation of methyl 4-(furan-2-yl)- and 4-(thiophen-2-yl)-2,4-dioxobutanoates with aromatic aldehydes and 1,3-thiazol-2-amine afforded 5-aryl-4-(hetaren-2-ylcarbonyl)-3-hydroxy-1-(1,3-thiazol-2-yl)-2,5-dihydro-1H-pyrrol-2-ones. Reactions of the latter with hydrazine and phenylhydrazine gave pyrrolo[3,4-c]pyrazol-6-ones and 3-phenylhydrazones, while the corresponding oximes were obtained in reactions with hydroxylamine.

5-aryl-3-hydroxy-1-(thiazol-2-yl)-4-(2-thienoyl)-1,5-dihydro-2H-pyrrol-2-ones were found to react with meta-phenylenediamine or 3-aminophenol forming pyrrolo[3,4-b]quinolin-3-ones. Using 4-amino-phenol and 3-methoxyaniline as reagents led to the formation of 3-arylamino derivatives. The identity of the obtained products was confirmed by IR, H-1 and C-13 NMR spectroscopy and mass spectrometry.

Methods of inhibiting
S. aureus
propagation, and screening for compounds that inhibit
S. aureus
propagation, are described. A method of inhibiting
S. aureus
propagation comprises either inhibiting or stabilizing ribosomal binding of a specific
S. aureus
tRNA in the
S. aureus
by an amount sufficient to inhibit
S. aureus
protein expression. A method of screening for compounds useful for inhibiting
S. aureus
propagation comprises contacting a specific
S. aureus
tRNA to a ribosome that binds that tRNA in the presence of the test compound and an mRNA that codes for methionine and arginine (i.e., includes the sequence AUGAGA), and then determining whether the compound inhibits the binding of that tRNA.
