Bloomycin A5 (Pingyangmycin) has the ability to stop tumor growth [2].
|
| ln Vivo |
Bleomycin A5 (Pingyangmycin) (oral; 18-day dose, 5 mg/kg) has been associated with anorexia, cachexia, skin ulceration, mortality, interstitial pneumonia, nephropathy, and focal necrosis of the adrenocortex [2].
Among the 65 patients, 41 were men and 24 were women (1.7:1 male:female ratio), the age range was 3 months to 45 years (mean, 12 years). Thirty-two lesions (49%) were macrocystic, 30 (46%) were microcystic, and 3 (5%) were combined. Each patient received 1 to 10 injections (mean, 3.0 injections) for the whole course of treatment, and the total dose of bleomycin A5 was from 8 to 80 milligrams (mean, 24.0 mg). Twenty-six of 32 macrocystic lesions (81%) showed greater than 90% reduction, whereas another 6 (19%) exhibited 50% to 90% reduction. Nineteen of 30 microcystic lesions (63%) showed greater than 90% reduction; 10 (33%) had 50% to 90% reduction; and 1 (4%) had less than 50% size reduction. Of the 3 combined lesions, 2 (67%) had greater than 90% shrinkage, and 1 (3%) had less than 50% reduction. The complications included ulceration of oral mucosa, minor soft tissue atrophy, mild fever, and hematoma. There was no recurrence throughout the follow-up period. Conclusion: These data suggest bleomycin A5 is a safe and effective intralesional agent for the treatment of macrocystic LMs, superficial oral mucosa LM, and localized deep microcystic lesions. For extensive macrocystic LMs involving contiguous anatomic areas and diffuse microcystic lesions involving deep tissues, bleomycin A5 injection combined with resection is necessary [1]. |
| Animal Protocol |
Of the 65 patients in the study, 60 patients were given intralesional injection of bleomycin A5. Five patients underwent partial resection, and then an injection of bleomycin A5 for the remaining lesion. The outcomes were assessed by physical examination and Doppler ultrasonography scan. The follow-up time was from 6 months to 3 years after the last injection (mean, 16 months). [1]

| Additional Infomation |
Pingyangmycin has been reported in Streptomyces verticillus with data available.
Pingyangmycin is the naturally-occurring bleomycin antineoplastic antibiotic isolated from the bacterium Streptomyces pingyangensisn. Pingyangmycin induces tumor cell apoptosis, possibly via a mechanism mediated by the mitogen-activated protein kinase (MAPK) pathway. (NCI04) See also: Bleomycin A5 (annotation moved to). Bleomycin A5 hydrochloride is a glycoside. Pingyangmycin is an anticancer drug known as bleomycin A5 (A5), discovered in the Pingyang County of Zhejiang Province of China. Bleomycin (BLM) is a mixture of mainly two compounds (A2 and B2), which is on the World Health Organization's list of essential medicines. Both BLM and A5 are hydrophilic molecules that depend on transporters or endocytosis receptors to get inside of cells. Once inside, the anticancer activities rely on their abilities to produce DNA breaks, thus leading to cell death. Interestingly, the half maximal inhibitory concentration (IC50) of BLMs in different cancer cell lines varies from nM to μM ranges. Different cellular uptake, DNA repair rate, and/or increased drug detoxification might be some of the reasons; however, the molecules and signaling pathways responsible for these processes are largely unknown. In the current study, we purified the A2 and B2 from the BLM and tested the cytotoxicities and the molecular mechanisms of each individual compound or in combination with six different cell lines, including a Chinese hamster ovary (CHO) cell line defective in glycosaminoglycan biosynthesis. Our data suggested that glycosaminoglycans might be involved in the cellular uptake of BLMs. Moreover, both BLM and A5 shared similar signaling pathways and are involved in cell cycle and apoptosis in different cancer cell lines.
