MedKoo CAT#: 530548

CAS#: 2061980-01-4

Description: XMU-MP-1 is a potent and selective MST1/2 inhibitor with IC50 values of 71.1 ± 12.9 nM and 38.1 ± 6.9 nM, respectively.. XMU-MP-1 blocked MST1/2 kinase activities, thereby activating the downstream effector Yes-associated protein and promoting cell growth. XMU-MP-1 displayed excellent in vivo pharmacokinetics and was able to augment mouse intestinal repair, as well as liver repair and regeneration, in both acute and chronic liver injury mouse models at a dose of 1 to 3 mg/kg via intraperitoneal injection.

More Info:

Biological target: XMU-MP-1 is a reversible and selective MST1/2 inhibitor with IC50s of 71.1 and 38.1 nM, respectively.
In vitro activity: To determine whether the Hippo signaling pathway mediated the biological functions of MST1 in BCa, the Hippo signaling pathway inhibitor, XMU-MP-1 (an inhibitor of MST1/2), was used to inhibit the function of the Hippo signaling pathway in BCa cells overexpressing MST1. RT-qPCR analysis demonstrated that the treatment of MST1-overexpressing cells with the inhibitor downregulated the expression levels of MST1 (Fig. 5A). The results of the CCK-8 and EdU incorporation assays revealed that the inhibited proliferative ability in the LV-MST1 group was partially restored in the LV-MST1 + XMU-MP-1 group (Fig. 5B and C). BCa cell migration was analyzed using wound healing assays; the results revealed that cell migration was also significantly increased in the MST1 + XMU-MP-1 cell group compared with the LV-MST1 group (Fig. 5D). Finally, western blotting analysis was performed to analyze the expression levels of key proteins in the Hippo signaling pathway. The expression levels of LATS1 and Bax were significantly downregulated, while the expression levels of YAP, Bcl-2 and Ki-67 were significantly upregulated in the LV-MST1 + XMU-MP-1 group compared with the LV-MST1 group in both cell lines (Fig. 6A and B).

In vivo activity: XMU-MP-1 administration attenuated AngII-induced aortic medial destruction in the ascending mouse aorta. In agreement with previous studies, AngII-induced medial destruction was associated with the accumulation of CD68+ macrophages throughout the intralamellar spaces on the adventitial site of the vessel wall. The beneficial effect of XMU-MP-1 on the attenuation of elastin fiber destruction in the aortic media is mainly due to its effect on the suppression of AngII-induced matrix metalloproteinases-2 (MMP2) production by infiltrated macrophages in the ascending aorta. In support, present data clearly suggested that XMU-MP-1 administration had no effect on AngII-induced macrophage infiltration into the ascending aortic medial layer or the total number of nuclei in the ascending aortic media, whereas it preserved or protected AngII-induced aortic medial destruction. These data suggest that XMU-MP-1 may exert its beneficial effect by suppressing MMP production or secretion by infiltrated macrophages into the aortic media.
