IM: To detect DNA damage
caused by fotemustine (Fot). METHODS: DNA damage in HL60 cells was
evaluated by modified alkaline elution technique. DNA interstrand
crosslink (ISC) and DNA protein crosslink (DPC) were determined.
Carmustine (Car) was used as control. Drug treatment time was 1 h .
RESULTS: After treatment with Fot 300 μmol·L -1 , ISC and DPC
index were 5 4 and 6 1 at 6 h, 2 7 and 1 2 at 12 h,
respectively. ISC reached the maximum at about 6 h. For Fot 100 μ
mol·L -1 , ISC and DPC index at ISC peak time were 2 1±0 9
and 3 55±0 23, 5 0±0 5 and 7 7±1 1 for Car 100 μmol·L
-1 , respectively. Single strand break (SSB) was induced by Fot.
CONCLUSION: Fot caused HL60 cell DNA ISC, DPC, and SSB. ISC was
formed more quickly by Fot than that by Car.
