BLEOMYCIN A5 HYDROCHLORIDE Chemische Eigenschaften,Einsatz,Produktion Methoden

Verwenden
Bleomycin A5 Hydrochloride is used as an anti-cancer drug used to combat various forms of carcinoma via activated-apoptosis of cancer cells.
Biologische Aktivität
bleomycin a5 is an anticancer chemotherapeutic that binds dna and induces dna cleavage and strand breaks, it is highly toxic. additionally, this compound induces apoptosis, alters cell cycle regulation, inhibits proliferation, and decreases tumor size in cellular and animal models of hemangioma. bleomycin may also inhibit thioredoxin reductase.
in vitro
the ic50 of blm alone to the cells was about 2.63 μg/ml. the ic50 of blm was decreased to 1/3.8 and 1/9.5 of 2.63 μg/ml when used in combination with 2.63 μg/ml and 5 μg/ml w-131 [1]. bleomycin a5 induced the activation of a jnk pathway in a dose-dependent manner. after 24h treatment, bleomycin a5 induced dramatic cell death. dapi nuclear staining assay revealed that pd98059 (10 μm) markedly enhanced bleomycin a5-induced apoptosis [2].
in vivo
in the rats, bleomycin a5 induced pulmonary inflammation and fibrosis, increased the levels of malondialdehyde and tumour necrosis factor-α and enhanced accumulation of collagen in the lungs. rolipram administration significantly attenuated these effects [3].
