MedKoo Cat#: 206485 | Name: Selinexor free base
Featured New

Description:

WARNING: This product is for research use only, not for human or veterinary use.

Selinexor, also known as KPT-330, is an orally bioavailable, potent and selective XPO1/CRM1 Inhibitor. Selinexor is effective in acquired resistance to ibrutinib and synergizes with ibrutinib in chronic lymphocytic leukemia. Selinexor potentiates the antitumor activity of gemcitabine in human pancreatic cancer through inhibition of tumor growth, depletion of the antiapoptotic proteins, and induction of apoptosis. Selinexor has strong activity against primary AML cells while sparing normal stem and progenitor cells.

Biological target:
XPO1/CRM1 inhibitor.
In vitro activity:
To determine whether the nuclear export protein XPO1 provides a target for radiosensitization, the effects of clinically relevant XPO1 inhibitor selinexor on the radiosensitivity of glioblastoma cells were evaluated. As determined by clonogenic survival analysis, selinexor enhanced the radiosensitivity of GSCs but not normal fibroblast cell lines. On the basis of γH2AX foci and neutral comet analyses, selinexor inhibited the repair of radiation-induced DNA double-strand breaks in GSCs, suggesting that the selinexor-induced radiosensitization is mediated by an inhibition of DNA repair. Consistent with a role for XPO1 in the nuclear to cytoplasm export of rRNA, selinexor reduced 5S and 18S rRNA nuclear export in GSCs, which was accompanied by a decrease in gene translation efficiency, as determined from polysome profiles, as well as in protein synthesis. In contrast, rRNA nuclear export and protein synthesis were not reduced in normal cells treated with selinexor.

In vivo activity:
To evaluate the potential of Selinexor to enhance GBM radiosensitivity under in vivo conditions, mice bearing NSC11 brain tumors (40 days post-implantation) were treated with a single dose of Selinexor (20mg/kg); tumors were collected at times out to 48h and polysome profiles generated from individual tumors. Representative profiles are shown in figure 6A along with the (translational efficiencies) TEs (mean ± SEM) generated from 3 mice. As reflected by the reduction in polysome fraction, TE was decreased by 1h after Selinexor administration reaching a maximum reduction by approximately 24h, which appeared to begin to recover towards untreated levels at 48h. These results indicate that Selinexor penetrates the blood-brain barrier and suggests that it targets the same processes within the tumor as detected in vitro. Based on the time course of the TE decrease, a protocol was designed to test the antitumor effectiveness the Selinexor/radiation combination. Selinexor treatment of mice alone had no significant effect on survival as compared to vehicle; radiation alone resulted in a significant increase in survival (Figure 6B). The survival of mice receiving the combination protocol was significantly increased as compared with control and, importantly, as compared with radiation alone. Whereas the median survival after Selinexor was not significantly different from vehicle, radiation alone increased median survival by 9 days and the combination by 18 days versus vehicle, indicating that the combination protocol increased tumor radiosensitivity with an apparent DEF of 2. Thus, these data suggest that Selinexor inhibits gene translation in orthotopic brain tumors and enhances their radiosensitivity.
