EFFECTS OF VERAPAMIL ON DNA, RNA AND PROTEIN SYNTHESIS OF HUMAN FIBROBLASTS / 中国药理学通报

In order to investigate the action of calcium antagonists on metabolism of intracellular macromolecules, The authors observed the effects of verapamil on the incor-poration of 〔 3H 〕 TdR, 〔 3H 〕 UR and 〔 3H 〕 Leu into human fibroblasts. The inhibitory effects on DNA and RNA synthesis were concentration dependent, ID50 was l2.3mg/L and 22mg/L, respectively. The inhibitory effect on the synthesis of protein was weak.
