Pingyangmycin (also known as Bleomycin A5) is an antitumor glycopeptide antibiotic belongs to bleomycin, which is produced by Streptomyces verticillus var. pingyangensis n.sp., a variety of Streptomyces verticillus. It was discovered in 1969 at Pingyang County of Zhejiang Province in China, and was brought into clinical use in 1978.

In China pingyangmycin has largely superseded bleomycin A2 (commonly known as "bleomycin"), since it is more effective, costs less, is easier to get, can treat a larger varities of cancers (such as breast cancer and liver cancer) and causes less lung injury. Even though it also results in pulmonary fibrosis, unlike bleomycin, its most serious side effect is anaphylactic shock, which is rare but may happen even in a low dose, and can be fatal. Besides, it causes more fever than bleomycin: the occurrence of this complication in patients is between 20% and 50%.
