4-Acetoxy-3-acetoxymethyl acetophenone (AAMAP) is mutagenic in Ames Salmonella typhimurium tester strains TA100 and TA98, which carry plasmid pKM101, but not in the isogenic plasmid-less strains TA1535 and TA1538. Similarly, no AAMAP-induced reversion of the his-4 allele is detectable in Escherichia coli K-12 umuC strains in the absence of the plasmid, even when the strains are treated with ethylene-diaminetetraacetate to increase permeability, or when the uvrB allele is introduced to increase… 
Investigation of Potential Genotoxic Effects of Low Frequency Electromagnetic Fields on Escherichia coli *
TLDR
It is concluded that low frequency electromagnetic fields do not increase spontaneous mutation, induce DNA repair or increase the mutagenic effects of UV or mitomycin C.

Select Acetophenones Modulate Flagellar Motility in Chlamydomonas
TLDR
Four acetophenones were screened for activity against positive phototaxis of Chlamydomonas cells, suggesting interference with activity of flagellar proteins and control of flagllar dominance.
