1966年，日本微生物学家梅泽宾夫首先从轮枝链霉菌(Streptomyces vertillus)中分离到BLM。
1969年，日本BLM，在日本授权为抗肿瘤药物。
1973年，日本BLM获美国FDA许可用于临床。目前已经发现了十余种博来霉素的天然成分，这些组分的机构之间仅在其氨基取代侧链上有所差别。
1969年，我国宋爱兰等专家，在温州平阳的南雁荡山仙姑洞前的土壤中分离出一株链霉菌（编号72），被取名为“争光霉素”，科研人员发现争光霉素与日本博莱霉索成分和作用相近，对鳞癌疗效更好，肺毒性反而低些。为了纪念这个菌种的产生地，后将争光霉素更名为平阳霉素(Ping yang mycin)，也称为博莱霉素A5（Bleomycin A5），是博莱霉素家族成员之一。其产生菌定名为“轮枝链霉菌平阳变种(S. Verticillus var. pingyangensis)”。
1978年，国家食品药品监督管理（SFDA）授权平阳霉素用于临床。
Bleomycin is chosen as the best-studied micronucleus 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. The IC 50 value of Bleomycin 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; IC 50 values are 14.2±2.8 nM and 13.0±1.1 nM, respectively.
Bleomycin 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.
Bleomycin (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.
