Putrescine, spermine, and spermidine were able to stimulate cell-free protein biosynthesis at low Mg++ ion concentrations. The addition of polyamines to the perfusate of an isolated perfused rat heart preparation caused an increased rate of [14C]phenylalanine incorporation into myocardial protein. Spermine increased the uptake of alpha-aminoisobutyric acid into the myocardium.
腐胺、精胺和亚精胺能够在低镁离子浓度下刺激无细胞蛋白质生物合成。向离体灌注大鼠心脏制剂的灌注液中添加多胺，会使[14C]苯丙氨酸掺入心肌蛋白的速率增加。精胺增加了α-氨基异丁酸进入心肌的摄取量。
