title: [Effect of alkylating derivatives of cyclic adenosine-3' ,5'-monophosphate on proliferation of mouse bone marrow stem cells].
abstract: The effect of the physiological concentration of cyclic adenosine-3' ,5'-monophosphate (cAMP) analogues on the proliferation of mouse bone marrow stem hemopoietic cells (CFUs) was examined. The stimulating effect was estimated from the decrease in CFUs expressed in the percentage derived from comparing the number of spleen colonies in the control and experimental groups treated with hydroxyurea 10(-3) M (incubation with hydroxyurea resuted in the cell death in S-phase). Cyclic AMP stimulted the proliferation of CFUs by 60%, while its analogues such as 8-(N-chloroacetylaminoethylamino)-cAMP, 1-(N-chloroacetylaminoethyoxy)-cAMP and 1-(N-(p-fluorosulfonyl)-benzoylaminoethoxy)-cAMP stimulated the proliferation by 39.2%, 32.4% and 21.9%, respectively. Therefore, the synthetic analogues of cAMP were not only far from inhibiting the proliferation of CFUs but, on the contrary, exerted a stimualting effect unlike most antineoplastic alkylating drugs that depress hemopoiesis up to its total aplasia.
