Abstract: | Study of the influence of the antitumor preparation chlofiden on RNA synthesis by sarcoma 45 and liver cells was carried out using 14C-orotic acid. Chlofiden was shown to activate RNA transport from the nucleus to the cytoplasm, and to reduce label incorporation into the nuclear and cytoplasmic RNA. Chlofiden increased the rate of RNA processes, which promoted some increase of label incorporation into low molecular RNA fraction of the nucleus and the cytoplasm. High and stable antitumor activity of chlofiden on sarcoma 45 was established. |
