Sensitized Photooxygenation of Ent-Pimaradiene Derivatives
Ésteres metílicos dos diterpenos ácido ent-pimara-9(11),15-dien-19-óico (1), ácido ent-pimara7,15-dien-19-óico (2) e ácido ent-pimara-8,15-dien-19-óico (3) foram submetidos a reações de fotooxigenação via formação sensibilizada de oxigênio singlete. Enquanto os compostos 2 e 3 foram totalmente convertidos nos produtos, o composto 1 reagiu apenas parcialmente sugerindo uma influência do impedime...
متن کاملFlash Photolytic Control of the Ca-concentration
Here we describe the subcellularly uniform control of the intracellular Ca2+ concentration ([Ca2+]i) by flash photolysis of caged Ca2+ or a caged Ca2+ buffer. A mixture of the two Ca2+ indicators fluo-3 and Fura-Red was used together with a laser-scanning confocal microscope to reveal spatial aspects of intracellular Ca2+ signals. The patch clamp technique in the whole-cell variant was applied ...
متن کاملDetermination of the pK values of the lumiflavin triplet state by flash photolysis.
Dependence of the lumiflavin triplet-triplet absorption spectrum on pH. Figure I shows the transient change in absorption when lumiflavin soJutions of pH = 2, pH = 7, and pH = 13 are flashed. From this the triplet-triplet absorption spectra of the acid (pH = 2), neutral (pH = 7), 1964; Kramer and Maute, 1972). The flash energy could be varied between 300 J and 900 J. The half duration of the fl...
متن کاملKetonization of the remarkably strongly acidic elongated enol generated by flash photolytic decarboxylation of p-benzoylphenylacetic acid in aqueous solution.
Photodecarboxylation of p-benzoylphenylacetic acid in aqueous solution produces the elongated enol 5, whose strength as an oxygen acid (pQ(E/a)= 7.67) makes it more acidic than simple enol analogs by several orders of magnitude.
متن کاملKinetic studies of adenine phosphoribosyltransferase.
The mechanism of reaction of adenine phosphoribosyltransferase from Ehrlich ascites tumor cells was investigated kinetically by initial velocity and product inhibition studies. The data are consistent with a mechanism in which 5-phosphoribosylpyrophosphate reacts with the enzyme to form an intermediate, presumably an enzyme-ribose 5-phosphate complex, with which adenine then reacts to form aden...
