争光霉素是属于碱性水溶性糖肽类抗癌抗菌素,自1971年鉴定投产以来,临床证明对鳞癌,特别是对头颈部鳞癌效果较好。经检定与日本博来霉素(Bleomycin)是同一类物质。但其主要组分不同,日本商品博来霉素的主要组分是 A_2,而争光霉素主要组分为 A_5,现此种单—A_5组分定名为“平阳霉素”,经实验证明对多种移植性动物肿瘤抑制率在90%以上,具有广谱抗肿瘤作
Conformalin is an alkaline, water-soluble glycopeptide anticancer antibiotic. Since its inception in 1971, it has been clinically proven to be effective against squamous cell carcinoma, particularly squamous cell carcinoma of the head and neck. It has been verified that it is the same type of substance as Bleomycin in Japan. However, its main components are different. The main component of bleomycins in Japan is A_2, and the main component of bleomycin is A_5. Now this mono-A_5 component is named “Pingyangmycin,” which has been proved by experiments. The tumor inhibition rate of various transplanted animals is above 90%, and it has a broad-spectrum anti-tumor effect.
