Sucrose acetate isobutyrate (SAIB) was tested for potential genotoxic activity in four different in vitro assay systems. Two independent trials of a Salmonella reverse mutation assay (using strains TA98, TA100, TA1535, TA1537 and TA1538) showed no increases in revertant frequencies at doses up to 10,000 microg/plate which was non-toxic but exceeded the solubility limit. Similarly, no mutagenic response was observed at doses up to 1000 microg/ml at the HGPRT locus in cultured CHO cells; SAIB was toxic and its solubility limit was exceeded at 50 microg/ml. No clastogenic activity was detected in cultured CHO cells at concentrations up to 2000 microg/ml. All three preceding in vitro tests were conducted both in the presence and absence of Aroclor 1254-induced rat liver S-9 metabolic activation systems. An unscheduled DNA synthesis assay also was performed using rat primary hepatocyte cultures with doses up to 1000 microg/ml, and no DNA repair was detectable. Thus, SAIB was stringently tested at doses exceeding the solubility limit in culture medium and causing toxicity to CHO cells without obtaining any evidence for genotoxic activity as a mutagen, clastogen, or DNA-damaging agent.
