Bleomycin sulfate is a DNA synthesis inhibitor. Bleomycin hydrochloride is a DNA damaging agent. Bleomycin sulfate is an antitumor antibiotic^[1].

DNA/RNA Synthesis^[1]

Bleomycin (BLM) sulfate is chosen as the best-studied micronucleus (MN) inducers in human lymphocytes with different mechanisms of genotoxicity. The most frequent Bleomycin-induced DNA lesions are single and double strand breaks and single apuinic/apyrimidinic sites. At the same time Bleomycin is true radiomimetic compound, resembling almost completely the genetic effect of ionizing radiation^[1].
The IC₅₀ value of Bleomycin sulfate for UT-SCC-19A cell line is 4.0±1.3 nM. UT-SCC-12A and UT-SCC-12B are both more resistant to Bleomycin (BLM); IC₅₀ values are 14.2±2.8 nM and 13.0±1.1 nM, respectively^[2].
Bleomycin sulfate (50, 100 μM; for 24, 48 h) induce pulmonary fibrosis in RLE-6TN cell (50 μM) and A549 cell (100 μM)^[4].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Bleomycin sulfate treatment (3.5-4.0 mg/kg; intra-tracheal) on day 0, body weights decreases by day 4 then increases by Day 7 through the end of the study^[3].
Bleomycin sulfate (3.5-4.0 mg/kg; intra-tracheal) produces a statistically significant increase in lung hydroxyproline levels, and also increases right caudal lung lobe mass^[3].
Bleomycin sulfate (intratracheal instillation; 5.0 mg/kg/day) induces pulmonary fibrosis in eighty 8-week-old male BALB/c mice with weight about 20-30 g. Bleomycin induces the expression levels of α-SMA and collagen I^[4].
Bleomycin sulfate (intratracheally; 2.5 mg/kg; 1.25 mg/ml, approximately 50 µl per mouse) induces pulmonary fibrosis in male C57BL/6 mice (8 weeks old, average weight approximately 24.5 g)^[5].
