Ro 5-4864 (4-chlorodiazepam), PK 11195 (1-(2-chlorophenyl)-1,3-dihydro-1-methyl-propyl)isoquinoline carboxamide) and diazepam inhibit, in a concentration-dependent way, the proliferation of V79 Chinese hamster lung cells (IC50 values were: 65.0 +/- 3.73 microM, 57.70 +/- 4.75 microM and 106.80 +/- 8.89 microM, respectively) without being cytotoxic. This antiproliferative effect is mediated by mitosis arrest in the G2 + M stage without affecting DNA synthesis and seems unrelated to a specific interaction of these drugs with the peripheral-type benzodiazepine receptor.
Ro 5-4864(4-氯地西泮)、PK 11195(1-(2-氯苯基)-1,3-二氢-1-甲基丙基)异喹啉甲酰胺)和地西泮以浓度依赖性方式抑制V79中国仓鼠肺细胞的增殖(IC50值分别为:65.0±3.73微摩尔、57.70±4.75微摩尔和106.80±8.89微摩尔),且无细胞毒性。这种抗增殖作用是由G2+M期的有丝分裂停滞介导的,不影响DNA合成,并且似乎与这些药物与外周型苯二氮䓬受体的特异性相互作用无关。
