Description and Uses
5-Chlorouracil (5-CU) may have advantages for the inhibition of undesired fibroblast proliferation taking place after surgery for glaucoma and results in filtration failure. A comparison of 5-CU and 5-fluorouracil (5-FU) cytotoxicity shows that 5-CU is approximately 1000 times less toxic to nonproliferative cells while maintaining good antimitotic activity. In addition, 5-CU induces apoptotic-controlled cell death, whereas the influence of 5-FU is by apoptonecrosis. The 5-CU apoptotic mechanism is driven mainly by the nuclear translocation of AIF and activation of the LEI/L-DNase II pathways, which are caspase-independent. In conclusion, even though 5-CU is a weaker antiproliferating agent than 5-FU, its reduced toxic side effects on the epithelium and sclera allow for its enhanced efficacy and extended reduction of IOP after filtering surgery for glaucoma. 5-CU is an effective mutagen, clastogen and toxicant, and an effective inducer of sister-chromatid exchange, and is not as sensitive to ionizing radiation as other thymine analogues[1].
5-Chlorouracil was used as a control in resazurin-based cytotoxicity assay for screening of cytotoxicity in hepatocytes and liver cell lines.
