产品简介:一种从 Dolabella auricularia 中提取的去甲肽,是一种有效的抗有丝分裂剂,在结构上与抗微管蛋白剂 Dolastatin 10 有关。
靶点:Auristatin
体外研究:Dolastatin 15 (DLS 15) induces cell cycle arrest at the G2/M phase followed by apoptosis in various human myeloma cell lines (RPMI8226, U266, and IM9). Dolastatin 15 induces apoptosis of myeloma cells via activation of both mitochondrial- and Fas (CD95)/Fas-L (CD95-L)-mediated pathways. Dolastatin 15 (DLS 15) displays growth inhibitory activity against all four SCLC cell lines (NCI-H69, NCI-H82, NCI-H345, NCI-H446) with IC50 values ranging from 0.039-28.8 nM, which were 2.7-9.2-fold higher than the values for dolastatin 10. All four SCLC cell lines underwent G2/M arrest within 24 hours of exposure to dolastatin 15.
体内研究:Dolastatin 15 conjugates to Trastuzumab via lysine residues at the drug C-terminus using a non-cleavable linker (Trastuzumab-amide-C-term-Dol15) produced target-dependent growth inhibition of cells endogenously expressing high HER2 levels (i.e., SK-BR-3, SK-OV-3) in vitro. This ADC was effective at varying doses (i.e., 10 and 20 mg/kg) in the SK-OV-3 human ovarian cancer xenograft.
