体外研究 |
埃坡霉素A是[3H]紫杉醇与微管蛋白聚合物结合的竞争性抑制剂。通过Hanes分析,Epothilone A的表观Ki值为1.4μM,Dixon分析的表观Ki值为0.6μM[1]。当应用于人T-24膀胱癌细胞系时,埃坡霉素A在体外具有高度细胞毒性(IC 50 =0.05μM)。基于竞争测定,埃坡霉素A与微管蛋白的结合亲和力与紫杉醇对微管蛋白的结合亲和力具有相同的数量级。从微管蛋白结合位点取出100nM(3H)紫杉醇的IC50对于紫杉醇为3.6μM,对于埃坡霉素A为2.3μM,对于patupilone为3.3μM[2]。 |

Identifying off-target effects and hidden phenotypes of drugs in human cells. Nat. Chem. Biol. 2 , 329-37, (2006)
We present a strategy for identifying off-target effects and hidden phenotypes of drugs by directly probing biochemical pathways that underlie therapeutic or toxic mechanisms in intact, living cells. …

Neuronal transcriptional repressor REST suppresses an Atoh7-independent program for initiating retinal ganglion cell development. Dev. Biol. 349 , 90-9, (2011)
As neuronal progenitors differentiate into neurons, they acquire a unique set of transcription factors. The transcriptional repressor REST prevents progenitors from undergoing differentiation. Notably…
