The electrochemical oxidation of oxalate at a platinum electrode in acetonitrile solutions as studied by cyclic and rotating-ring disk voltammetry and controlled potential coulometry shows an irreversible two-electron oxidation at ca. 0.3 V vs. SCE to CO2 with no intermediates detectable by these techniques. The oxidation of oxalate in the presence of several fluorescers (such as rubrene, 9, IO...

shop. I am indebted for capable research assistance to Naomi Roht-Arriaza and Ellen Hertz. Ellen played a particularly vital role, providing conceptual enrichment, incisive intellect and warm nurturance throughout the finishing stages of this project. My special thanks go to James Tessier whose intellectual and personal contributions extend far beyond ordinary research assistance. Without Jim's...

The potency of oxalyl amino acid derivatives as inhibitors of prolyl 4-hydroxylase was studied in vitro, in isolated microsomes and in chicken embryonic-tissue culture. These compounds represent structural analogues of 2-oxoglutarate in which the -CH2- moiety at C-3 is replaced by -NH-, with or without further structural modifications. The most efficient inhibitor of purified prolyl 4-hydroxyla...

We studied hydrogen-bonding assemblies in a series of dumbbell-shaped hydrazine derivatives, namely oxalyl N',N'-bis(3,4-dialkoxybenzoyl)-hydrazide (BFH-n, n = 4, 6, 8, 10) and oxalyl N',N'-dibenzoyl-hydrazide (FH-0). It has been demonstrated that NH-1 protons of BFH-n precipitated from tetrahydrofuran (THF) or dimethylformamide (DMF) were involved in intramolecular H-bonding to form 6-membered...

In this investigation, new structures based on homoisoflavonoids were designed. Homoisoflavonoids are considered as an important class of flavonoids with various biological properties such as cytotoxicity. A new series of benzylidene-6,7-dihydro-8H-[1,3]dioxolo[4,5-g] chromen-8-one derivatives were developed and their cytotoxic activities evaluated for all compounds on three human breast cancer...

Cell-free lysates of the strict anaerobe Oxalobacter formigenes contained the following enzymatic activities: oxalyl coenzyme A reductase, glyoxylate carboligase, tartronic semialdehyde reductase, and glycerate kinase. NAD(P)-linked formate dehydrogenase, serine-glyoxylate aminotransferase, and NAD(P) transhydrogenase activities were not detected. These results support the hypothesis that O. fo...
