Description: IITZ-01 (Autophagy inhibitor IITZ-01) is a novel potent lysosomotropic autophagy inhibitor. IITZ-01 enhances autophagosome accumulation but inhibit autophagosomal degradation by impairing lysosomal function, finally resulting in the inhibition of autophagy. IITZ-01 exhibited more than 10-fold potent autophagy inhibition along with 12- to 20-fold better cytotoxic action than CQ. IITZ-01 is potent autophagy inhibitor with single-agent anticancer activity and awaits further preclinical development as potential anticancer therapeutic.

More Info: Autophagy is a homeostatic process that recycles damaged organelles and long-lived proteins by delivering them in double-membrane vesicles to lysosomes for degradation. Autophagy has a prominent role in survival, proliferation, and resistance of tumors in metabolic and chemotherapeutic stress conditions. Clinical trials with chloroquine-a known autophagy inhibitor-were unable to achieve complete autophagy inhibition in vivo, warranting the search for more potent autophagy inhibitors

Biological target: IITZ-01 is a potent lysosomotropic autophagy inhibitor with single-agent antitumor activity, with an IC50 of 2.62 μM for PI3Kγ.
In vitro activity: Sub-lethal concentrations of a lysosomotropic autophagy inhibitor, IITZ-01, sensitizes cancer cells (renal, lung, and breast carcinoma) to TRAIL-induced apoptosis through DR5 upregulation and survivin downregulation through ubiquitin-proteasome pathway. Knockdown of DR5 or overexpression of survivin inhibited combined treatment with IITZ-01 and TRAIL-induced apoptosis. IITZ-01 downregulated protein expression of Cbl, ubiquitin E3 ligase, and decreased expression level of Cbl markedly led to increase DR5 protein expression and TRAIL sensitivity. Moreover, IITZ-01 decreased expression level of survivin protein via downregulation of deubiquitinase ubiquitin-specific protease 9X (USP9X) expression. Taken together, these results provide the first evidence that IITZ-01 enhances TRAIL-mediated apoptosis through DR5 stabilization by downregulation of Cbl and USP9X-dependent survivin ubiquitination and degradation in renal carcinoma cells.

In vivo activity: The antitumor efficacy of IITZ-01 was investigated in in-vivo breast cancer model. MDA-MB-231/green fluorescent protein (GFP) orthotropic breast cancer xenografts were developed in CrTac:NCr-Foxnnu BALB/c female nude mice. Tumors after reaching ~100 mm3, vehicle, 45 mg/kg of IITZ-02, were administered through intraperitoneal (i.p.) route on every alternate day for 4 weeks. IITZ-01 reduced the active tumor burden around 8.8-fold when compared with control group as determined by tumor photon counts. Moreover, tumor volume measurements have demonstrated that IITZ-01 significantly inhibited average tumor growth when compared with control from third day of treatment (Fig. 7a–c). Significant reduction in average tumor weights was observed after treatment with test compounds compared with control (Fig. 7d). This treatment schedule of both compounds was well tolerated in mice for the total duration of administration with no significant changes in their body weights (Fig. 7e). In addition, hematoxylin and eosin staining revealed large areas of necrosis in treated groups of both compounds when compared with controls. Immunohistochemistry in histological sections revealed that exposure of both compounds have enhanced LC3-II- and PARP-positive staining in cells than vehicle control, indicating effective autophagy inhibition and triggering of apoptosis (Fig. 7f). Altogether, these findings demonstrated that IITZ-01 inhibits breast tumor growth by autophagy inhibition and apoptosis induction in vivo.
