The heterocyclic structure of the pyrazoline obtained from reaction of 2,4-pentanedione with 4-methyl-3-thiosemicarbazide has been confirmed by X-ray crystallography. Reactions of the pyrazoline with CuII and ZnII have been probed by EPR and NMR spec

Exposure of aqueous solutions of the sodium salt of DNA to ionizing radiation at 77 K gives trapped electron-loss and electron-gain centers in the stacked bases that were well characterized by EPR spectroscopy. We find that when mitoxanthrone and AQ4

Solar UV light can be dangerous to cellular systems. One manifestation of this is the formation of thymine dimers, containing cyclobutane rings, in suitable regions of duplex DNA. Fortunately, these dangerous defects are rapidly recognized by a numbe

Electron spin resonance spectra of spin labeled tetracycline (TC-SL) do not show any recognizable partitioning into a lipid bilayer or bulk hydrocarbon solvent, paraffin oil. TC-SL, however, penetrates through the model and biological membranes. It i

ESR studies of two copper(II) complexes of substituted dibenzotetraaza[14]annulenes, CuL and CuLA, in dimyristoylphosphatidylcholine (DMPC) and egg yolk phosphatidylcholine (EYPC) are reported. Our data show that both complexes partition into the mem

Electron loss from N-(2-mercaptopropionyl) glycine (PSH) gave an EPR detectable radical anion, PS-.SP(-). When the PSH derivative was frozen in aqueous DNA solutions to 77 K and exposed to ionizing radiation, normal damage to the DNA was detected by
