CBB1003 is a novel histone demethylase LSD1 inhibitor with IC50 of 10.54 uM.IC50 value: 10.54 uM [1]Target: LSD1 inhibitorin vitro: Treatment of F9 cells with CBB1003 led to the activation of CHRM4 and SCN3A expression. Treatment of CBB1003 led to significant growth inhibition of mouse embryonic teratocarcinoma F9 cells. Treatment of mouse ES cells with CBB1003 and 1007 also led to substantial inhibition of the spherical growth of ES cells [1]. CBB1003 inhibited CRC cell proliferation and colony formation. In cultured CRC cells, inhibiting LSD1 activity by CBB1003 caused a decrease in LGR5 levels while overexpression of LGR5 reduced CBB1003-induced cell death [2].

CBB1003, a lysine-specific demethylase 1 inhibitor, suppresses colorectal cancer cells growth through down-regulation of leucine-rich repeat-containing G-protein-coupled receptor 5 expression
J Cancer Res Clin Oncol 2015 Jan;141(1):11-21.PMID:25060070DOI:10.1007/s00432-014-1782-4
Purpose: Lysine-specific demethylase 1 (LSD1) was highly expressed in several malignancies and had been implicated in pathological processes of cancer cells. However, the role of LSD1 in colorectal cancer (CRC) carcinogenesis, prognosis and treatment remains uncharacterized. Methods: In this study, we examined LSD1 expression in paraffin-embedded CRC specimens from 295 patients, including 65 patients with paired samples of colorectal carcinoma, adjacent adenoma and normal colorectal tissues. Using an LSD1 inhibitor, CBB1003, as a probe, we studied the association between LSD1 and leucine-rich repeat-containing G-protein-coupled receptor 5 (LGR5), a CRC stem cell marker involved in carcinogenesis. The anti-tumor effects of CBB1003 on CRC cells were also examined. Results: LSD1 expression was significantly elevated in colorectal tumor tissues compared with adjacent adenoma and normal colorectal tissues (P < 0.001), and LSD1 levels were significantly correlated with an advanced AJCC T stage (P = 0.012) and distant metastasis (P = 0.004). CBB1003 inhibited CRC cell proliferation and colony formation. In cultured CRC cells, inhibiting LSD1 activity by CBB1003 caused a decrease in LGR5 levels while overexpression of LGR5 reduced CBB1003-induced cell death. We also observed the inactivation of β-catenin/TCF signaling after CBB1003 treatment, consistent with the positive correlations among LSD1, LGR5, β-catenin and c-Myc expression in human colon tumor and adenoma tissues. Conclusion: Our result suggested that LSD1 overexpression promotes CRC development and that the LSD1 inhibitor inhibits CRC cell growth by down-regulating LGR5 levels and inactivates the Wnt/β-catenin pathway. Thus, LSD1 and its inhibitor might provide a new target or a useful strategy for therapy of CRC.
