生物活性:
Peplomycin (Bleomycin PEP; Pepleomycin) is an antibiotic analogue of Bleomycin (HY-108345), with high antitumor effect and less pulmonary toxicity. Peplomycin induce apoptosis in oral squamous carcinoma cell line SSCKN cells and pulmonary fibrosis in rats.

体内研究:
Peplomycin (5 mg/kg; once daily) induces rat pulmonary fibroblasts to myofibroblasts (MF), while the peripheries of lungs adjacent to the pleura reveals advanced fibrosis with a small number of alpha-smooth muscle actin (alpha-SMA)-positive MF, which ultrastructurally possessed abundant microfilaments and cellular organelles.

体外研究:
Peplomycin (0-100 μM; 30 h) inhibits human oral squamous carcinoma cell line SSCKN and SCCTF cells in a dose-dependent manner.Peplomycin (1 μM and 10 μM; 30 h) results nuclear fragmentation and condensation of chromatin in cells dose-dependently and induces apoptosis.Peplomycin (5 mg/mL; 7 d) induces pulmonary fibrosis separated from saline-injected rats (N-Fib) by differentiating fibroblasts to alpha-SMA-positive MF.
