Description: Elraglusib, also known as 9-ING-41, is a glycogen synthase kinase-3 (GSK-3) inhibitor. 9-ING-41 leads to cell cycle arrest, autophagy and apoptosis in bladder cancer cells. 9-ING-41 enhanced the growth inhibitory effects of gemcitabine or cisplatin when used in combination in bladder cancer cells. 9-ING-41 sensitized bladder cancer cells to the cytotoxic effects of human immune effector cells.

More Info:

Biological target: 9-ING-41 is a maleimide-based ATP-competitive and selective glycogen synthase kinase-3β (GSK-3β) inhibitor with an IC50 of 0.71 μM.
In vitro activity: 9-ING-41 was tested in T24, HT1376 and RT4 bladder cancer cell lines. 9-ING-41 treatment resulted in a decreased growth of bladder cancer cells at 0.25–1 μM concentrations in a dose-dependent manner with GI50 range of 0.4–0.5 μM (Fig. 1A). Moreover,a cytotoxic effect of 9-ING-41 was found in RT4 bladder cancer cells at >0.5 μM concentrations of 9-ING-41 (Fig. 1A). Cell cycle blockage was found at G2/M after 24 hours of 9-ING-41 treatment (Fig. 1C), suggesting that GSK-3 inactivation by 9-ING-41 halts progression of mitosis in bladder cancer cells. To investigate the mechanistic effect of GSK-3 inhibitor 9-ING-41 in the blockage of cell cycle in bladder cancer cells, the expression of G2/M regulatory proteins Cdk1 and Cyclin B1 was examined in 9-ING-41-treated cells. It was found that expression of Cdk1 and Cyclin B1 proteins was significantly decreased in 9-ING-41-treated bladder cancer cells (Fig. 2A). Moreover, treatment with 9-ING-41 led to a decreased expression of antiapoptotic molecules, Bcl-2 and XIAP, resulted in an increased apoptosis as shown by PARP cleavage in bladder cancer cells (Fig. 2A,B). Furthermore, caspase activation assay was used to demonstrate that 9-ING-41 treatment induces apoptotic cell death in bladder cancer cells (Fig. 2C). These in vitro results suggest that treatment with GSK-3 inhibitor 9-ING-41 suppresses expression of G2/M regulatory proteins and antiapoptotic molecules leading to cell cycle arrest and apoptosis in bladder cancer cells, and identify 9-ING-41 as a candidate for the targeted therapy of human bladder cancer.

In vivo activity: In these studies, 9-ING-41 treatment was initiated 7 days after instillation of the adenoviral vectors. 9-ING-41 significantly improved decrements (p < 0.05) in lung compliance and lung volume compared to TGF-β adenoviral treated mice (Fig. 6A). Lung injury by morphometry was next analyzed using a 3-point scale, where 1 = no scarring and 3 = extensive scarring. 9-ING-41 treatment significantly reduced the lung injury score of TGF-β adenovirus induced PF in mice (Fig. 6B, p = 0.02). Collagen deposition (Fig. 6C) was likewise significantly reduced by 9-ING-41 treatment (Fig. 6C, p = 0.03). TGF-β adenovirus treated mice also demonstrated significantly increased numbers of apoptotic cells compared to GFP adenovirus controls. 9-ING-41 treatment significantly reduced the number of apoptotic cells, presumably including alveolar epithelial cells, in TGF-β treated mice compared to GFP adenoviral controls (Fig. 6D). While DMSO treated mice showed pronounced injury and areas of intense collagen deposition, 9-ING-41 treated mice had significantly fewer areas of injury and demonstrated less collagen deposition (Fig. 7B). These findings strongly support the hypothesis that the therapeutic targeting of GSK-3β with the novel inhibitor, 9-ING-41, reduces myofibroblast differentiation, collagen deposition, and subsequent PF in vivo.
