(Z,Z)-Muconaldehyde reacts with primary amines, including valine and lysine (epsilon-amino), to afford N-substituted-2-(oxoethyl)pyrroles, which were reduced with sodium borohydride to the more stable N-substituted-2-(hydroxyethyl)pyrroles. The formation of the pyrrole aldehydes was performed in a variety of solvents including aqueous methanol.
A series of 2-amino-9-(3-azido-2,3-dideoxy-beta-D-erythro-pentofuranosyl)-6- substituted-9H-purines was synthesized and tested for the ability to protect MT4 cells from the cytopathic effect of HIV-1IIIB. These compounds were prepared by a combination of chemical and enzymatic reactions. Some of the nucleoside analogs with

Peroxynitrite reacts with 2',3',5'-tri-O-acetyl-guanosine to yield a novel compound identified as 1-(2,3,5-tri-O-acetyl-beta-D-erythro-pentofuranosyl)-5-guanidino-4-nitroimidazole (6). This characterization was achieved using a combination of UV/vis spectroscopy and ESI-MS. Additionally, 1-(beta-D-erythro-pentofuranosyl)-5-guanidino-4-nitroimidazole (6a) was synthesized by an independent route, characterized by UV/vis spectroscopy, ESI-MS, and
Various drugs known or expected to increase the levels of cyclic nucleotides in cells were applied to isolated superfused frog retinae, and their influence on the aspartate-isolated a-wave was studied. Isobutylmethylxanthine (IBMX), triacetylguanosine (TAG), and dimethylaminopurine (DAMP) strongly influenced the
