A802715 is a methylxanthine derivative. A802715 has a TD₅₀ (toxic dose of 50%) of 0.9-1.1 mM.

The toxicity of the methylxanthine derivative A802715 is determined against the two human melanoma lines, Be11 and MeWo, and against the two human squamous cell carcinoma lines, 4197 and 4451, by vital dye staining assay. A802715 has a TD₅₀ of 0.9-1.1 mM and is the most toxic. In p53 wt cells BrdU incorporations show that the irradiation-induced suppression of S-phase entry is strongly enhanced by A802715. A802715 prolongs the G₂/M block or remain ineffective depending on the p53 status of the cell line^[1].

DNA analysis is performed using a FACScan flow cytometer emitting a 488 nm beam. Red fluorescence from PI emission is collected as a linear signal through a 600 nm bandpass filter and recorded as a measure of total DNA content. Processing the red fluorescence into height, area and width (doublet discrimination mode) eliminated cell doublets. Data are collected in list mode and 10000 events are recorded per sample and displayed as a frequency distribution histogram. Estimates of the percentages of cells in the different periods of postirradiation incubation with marker statistics reveal the time at which the G₂/M block is maximally expressed. These times are used for each cell line as a starting point at which the methylxanthine drugs were added. Cell debris, nuclei doublets and triplets were excluded by gating^[1].
