The relationship between lipophilic-hydrophilic balance, uptake and anti-bacteriophage lambda activity of experimental anti-tumour bisquaternary salts.

The uptake by Escherichia coli of a series of bisquaternary experimental anti-tumour agents (quinolinium 4-[p-9(-pyridylamino)phenylcarbamoyl]-aniline-bisalkyl dibromides) has been measured both by association of radiolabelled compounds and their inhibition of the vegetative replication of bacteriophage lambda (after heat inactivation of the phage repressor… CONTINUE READING
