Abstract: The present invention relates to a new pharmaceutical composition with synergistic properties, to dosage units thereof, and to the use of the said composition and dosage units in the human or veterinary practice for the treatment of patients suffering from infectious diseases. The composition contains as active ingredients an amidinopenicillanic acid derivative of the formula ##STR1## in which R is hydrogen or a lower alkanoyloxymethyl radical including the pivaloyloxymethyl radical or atoxic salts thereof in combination with 2,4-diamino-5(3,4,5-trimethoxybenzyl)-pyrimidine, also known under the name trimethoprim, used hereinafter, or atoxic salts thereof.

Abstract: This involves an in vitro assay system to screen for mutagenic and/or carcinogenic agents based on alterations in the fidelity of DNA synthesis. In the system, chemicals will be tested for their mutagenicity or carcinogenicity by measuring increases in the number of mistakes incorporated by purified DNA polymerases using synthetic polynucleotide templates. This system offers the advantage of performing this analysis in the test tube so that all parameters in the reaction can be monitored. Agents that enhance misincorporation during DNA synthesis would be predicted to have a higher probability of being mutagens or carcinogens in the human population.
