N,N'-Diacetylputrescine (tetramethylenebisacetamide [TMBA]) and its six carbon analog, hexamethylenebisacetamide (HMBA), inhibited the proliferative response of human B lymphocytes to anti-mu and formalinized Cowan I strain Staphylococcal aureus (SAC) stimulation. In contrast, B cell growth factor-stimulated proliferation of human B cells

A novel type of N-acetyltransferase, clearly different from the nuclear and cytosolic polyamine N-acetyltransferases of mammals, was recently found in the intestinal nematode Ascaris suum. The occurrence of this putrescine N-acetylating enzyme has also been noted in the filarial parasite

A gas chromatographic method was developed for the determination of monoacetylputrescine, monoacetylcadaverine, N1-acetylspermidine and N8-acetylspermidine in human urine. The amines were isolated from urine by silica gel column chromatography. 1,10-Diaminodecane was used as internal standard. The amines were reacted with

In a single, rapid and precise analysis, monoacetylputrescine, N8-acetylspermidine, N1-acetylspermidine, putrescine, spermidine, and spermine can be separated using a five-buffer system on an automatic amino acid analyzer. This method allows, for the first time, the separation of all the known
1,3-Diaminopropane has been identified as the major polyamine of Acanthamoeba culbertsoni. N-acetylputrescine and spermidine were present in appreciable amounts and putrescine as well as N-acetylspermidine were also detected, but spermine was absent. Changes in polyamine levels were observed during the
