产品描述
|
SCR7 is a molecule that inhibits joining of DSBs in cell-free repair system; inhibits NHEJ (nonhomologous end-joining) in a Ligase IV-dependent manner within cells, and activates the intrinsic apoptotic pathway.

体外研究

SCR7 does not induce DSBs directly to the genome and is Ligase IV dependent. Besides, upon incubation of oligomeric dsDNA or supercoiled plasmid DNA with increasing concentrations of SCR7, there was no evidence for DNA breaks. Accumulation of DSBs leads to cell death upon SCR7 treatment with a dose-dependent decrease in cell proliferation of MCF7, A549, and HeLa with an IC50 of 40, 34 and 44μM, respectively, which was further confirmed by DIC imaging in MCF7. T47D, A2780 and HT1080 were also sensitive to SCR7, with an IC50 of 8.5, 120, and 10μM, respectively. SCR7 encapsulated micelles (ES) were also characterized by small-angle neutron scattering (SANS). Encapsulated SCR7 treatment resulted in accumulation of DNA breaks within the cells, resulting in cell cycle arrest at G1 phase and activation of apoptosis.

体内研究
|
SCR7 treatment (10mg/kg, six doses) significantly reduced breast adenocarcinoma-induced tumor in mice. Untreated tumor animals survived only for 52 days, whereas treated animals exhibited ~4-fold increase in lifespan. Treatment with SCR7 resulted in regression of tumors with no obvious adverse effects. In addition, HPLC analysis of serum following administration of SCR7 into mice (20mg/kg) showed bioavailability of 114μg/ml and a t1/2 of 1hr.
