Currently two injectable products of diethylenetriaminepentaacetic acid (DTPA) are U.S. Food and Drug Administration (FDA)-approved for decorporation of (241)Am; however, an oral product is considered more amenable in a mass casualty situation. The d

Potassium permanganate oxidation of 1-aryl-5-(4-pyridyl)-1,2,3-triazolines I in a benzene-water two-phase system using the phase-transfer catalyst tetrabutylammonium chloride yields the corresponding 1H-1,2,3-tri-azoles II. However, when the reaction

The rational design and synthesis of a series of peptidyl carbamates incorporating a derivatized ornithyl or lysyl residue at the P3 or P4 subsite is described. The derivatized residues were chosen as mimics of desmonsine cross-links ubiquitously fou

Twenty-six novel peptidyl carbamates and thiocarbamates were synthesized and evaluated as elastase inhibitors. Eighteen compounds inhibited porcine pancreatic elastase, whereas only eleven of the newly synthesized compounds inhibited human leukocyte

The effect of structural variations on the rates of elastase-catalyzed hydrolysis of model carbonate and carbamate esters was studied using HPLC. It is shown that branching in the immediate vicinity of the carbonate or carbamate functionally results

The design and synthesis of 13 novel peptidyl carbamates are described. When tested for inhibitory activity toward porcine pancreatic elastase, trypsin, and chymotrypsin, six compounds were found to specifically inhibit elastase without affecting the

Six carbamate derivatives were tested for inhibitory activity towards porcine pancreatic elastase, trypsin, and chymotrypsin. Only three esters that are isatoic anhydride derivatives were found to inhibit elastase competitively but nonspecifically. K

Cyclobutanone reacts with diphenyl-1,2,4,5-tetrazine, in alcoholic base and in diethylamine, to give 3,8-diphenyl-6,7-dihydro-1,2-diazocin-4(5H)-one (5) and 4-diethylamino-3,8-diphenyl-6,7-dihydro-1,2-diazocine (8) respectively. With diethylamine the

A cyclic somatostatin analog was compared to an iodinated analog of the same compound with respect to organ distribution and biliary excretion in the rat. The cyclic hexapeptide was radiolabeled with either 14C or 131I (tyrosine). Organ distribution

New 1,2-diaryl- and 1,2,6-triarylpyridinium salts, containing various five- and six-membered heteroaromatic substituents in the 1, 2, and 6-positions of the pyridinium ring, were synthesized. New tetra- and hexacyclic compounds were prepared by photo
