Effects of cannabinoids on L1210 murine leukemia. 1. Inhibition of DNA synthesis.

Abstract

The effect of cannabinoid derivatives on thymidine-3H uptake in L1210 murine leukemia was determined. In experiments at 200 mg/kg 3 hrs after treatment, the order of activity was delta9-tetrahydrocannabinol less than cannabinol less than cannabidiol less than abnormal cannabidiol less than 11-hydroxy-delta9-tetrahydrocannabinol less than delta8-tetrahydrocannabinol. The inhibitory effect of delta8-tetrahydrocannabinol was 99%. When animals were dosed on consecutive days with delta9-tetrahydrocannabinol and killed on the third day, thymidine-3H incorporation was increased while delta8-tetrahydrocannabinol retained its inhibitory activity under the same conditions. Delta-9-tetrahydrocannabinol and delta8-tetrahydrocannabinol inhibited RNA and protein synthesis in a fashion analagous to the inhibition of DNA synthesis.
