描述:

Bleomycin Sulfate是一种糖肽类抗生素,作用于UT-SCC-19A细胞,IC50为4 nM。

溶解性:DMSO : 93 mg/mL (61.5 mM)
Water 92 mg/mL (60.8 mM)

体外研究:

UT-SCC-12A and UT-SCC-12B are both more resistant to Bleomycin sulfate with IC50 of 14.2 nM and 13 nM, respectively. Alveolar macrophages incubated with 0.01 μg/mL to 1μg /mL Bleomycin sulfate for 18 hours secretes significantly more fibroblast growth factor than macrophages incubated without Bleomycin sulfate. Macrophages stimulated with Bleomycin sulfate continues to produce significant amounts of fibroblast growth factor even after Bleomycin sulfate is removed and replaced with fresh (Bleomycin sulfate-free) media. Fibroblast growth factor secretion by Bleomycin sulfate-stimulated alveolar macrophages is inhibited by cycloheximide, and the 5-lipoxygenase inhibitors NDGA (nordihydroguaiaretic acid) and BW755c, indicating not only a requirement for protein synthesis but also for metabolites of the 5-lipoxygenase pathway of arachidonic acid metabolism for full expression of activity. Bleomycin sulfate (400 μg/mL) incubation for 24 hours decreases the viability of NTera-2 cells, and increases caspase-3, -8 and -9 activities, Bax and cytoplasmic cytochrome c levels and decreases Bcl-2 levels. In terms of unstable aberrations, the clastogenic effect of Bleomycin sulfate on ADIPO-P2 cells persists for at least 10 days after exposure. Bleomycin sulfate-induced telomere instability in mammalian cells persists for several generations after exposure. Moreover, the appearance of telomere fusions in Bleomycin sulfate-exposed cells 10 days after treatment suggests that Bleomycin sulfate can induce delayed telomere instability.

体内研究:Day 7 post-Bleomycin sulfate, CD45+ cells in BALf in NOX-/- is 1.7-fold > WT, 57% of which are Mf that decreases by 67% in WT and 83% in NOX-/- by Day 21.
