Benzylidene-oxazolones as photoswitches: Photochemistry and theoretical calculations
Funes-Ardoiz, Ignacio,Blanco-Lomas, Marina,Campos, Pedro J.,Sampedro, Diego
, p. 9766 - 9771 (2013/10/22)
The photophysics and photochemistry of a family of compounds proposed as efficient molecular photoswitches is presented. The effect of different light sources, substituents and solvents in the photostationary state has been explored. A detailed mechanisti
Benzylidene-oxazolones as molecular photoswitches
Blanco-Lomas, Marina,Campos, Pedro J.,Sampedro, Diego
, p. 4334 - 4337 (2012/10/29)
The synthesis and photochemical study of a family of molecular switches inspired by the green fluorescent protein (GFP) chromophore is presented. These compounds can be easily synthesized, and their photophysical properties may be tuned. Due to their effi
Oxazolones: New tyrosinase inhibitors; synthesis and their structure-activity relationships

, p. 6027 - 6033 (2007/10/03)
The tyrosinase inhibitory potential of seventeen synthesized oxazolone derivatives has been evaluated and their structure-activity relationships developed in the present work. All the synthesized derivatives, 3-19, demonstrated excellent in vitro tyrosina

An influence of a structure of the amine (benzylamine, N-methyl-benzylamine, N-isopropyl-benzylamine, N-methyl-butylamine, N-ethyl-butylamine, sec-butylamine, and tert-butylamine) on a rate constant of the ring-opening reaction of 4-benzylidence-2-methyl-
Chemocontrolled reduction of aromatic α-ketoesters by NaBH4: Selective synthesis of α-hydroxy esters or 1,2-diols
Dalla, Vincent,Cotelle, Philippe,Catteau, Jean Pierre
, p. 1577 - 1580 (2007/10/03)
α-Hydroxyesters 5a-g or diols 6a-g have been obtained in high yields by reduction of aromatic α-ketoesters 4 once or twice respectively by using NaBH4 as the reducer under suitable conditions. The use of a solvent that does not interact with the reagent allowed the double reduction to occur with only a slight excess of borohydride in very mild conditions.
Synthesis of substituted quinazolone derivatives as potential anti-HIV agents (part III)
Desai,Bhatt,Shah,Undavia,Trivedi,Narayanan
, p. 361 - 366 (2007/10/03)
Several 1-[2-phenyl-4(4H)-oxo-3-quinazolinyl]-2-methyl-4-arylidine -5-oxo-imidazolines (Va-1), 2-phenyl-3-(aroyl amino)-4(4H)-oxo quinazolines (Vla-I) and N1-2-methyl-4(4H)-oxo-3-quinazolinyl-N2-aryl-thioureas (Vlla-k), have been synthesised and tested for anti-HIV activity. The structures of these compounds have been established on the basis of elemental analysis and spectral data.
