LD-110 triTFA
Based on 1 Customer Validation
LD-110 triTFA is a PROTAC degrader targeting LSD1 with a DC50 of 0.44-1.24 μM. LD-110 triTFA acts through the CRBN E3 ubiquitin ligase and the ubiquitin-proteasome system, leading to H3K4me2 accumulation. LD-110 triTFA induces apoptosis and inhibits the growth and survival of multiple esophageal squamous cell carcinoma (ESCC) cell lines. LD-110 triTFA inhibits tumor growth in the KYSE-150 xenograft model. LD-110 triTFA can be used in research related to esophageal squamous cell carcinoma.

In Vitro
LD-110 (10 μM; 6-72 h) triTFA degrades LSD1 and increases H3K4me2 levels in KYSE-150, KYSE-30, and EC9706 ESCC cells in a time-dependent manner[1].
LD-110 (48 h) triTFA treatment significantly increases H3K4me2 levels in KYSE-150, KYSE-30, and EC9706 ESCC cells[1].
LD-110 (0.1-30 μM; 48 h) triTFA potently and dose-dependently degrades LSD1 and induces H3K4me2 accumulation in KYSE-150, KYSE-30, and EC9706 esophageal squamous cell carcinoma cells[1].
LD-110 triTFA specifically degrades LSD1 in KYSE-150 cells without affecting the levels of other components of the LSD1 complex[1].
LD-110 (72 h) triTFA effectively inhibits the growth of KYSE-150, KYSE-30, and EC9706 ESCC cells with low micromolar IC50 values[1].
LD-110 (1-10 μM; 10-14 days) triTFA effectively inhibits clonogenic survival of KYSE-30 and EC9706 cells[1].
