BETd-260
Based on 4 publication(s) in Google Scholar
BETd-260 (ZBC 260) is a BET PROTAC degrader. BETd-260 recruits BRD2, BRD3, and BRD4 to the CUL4-RBX1-DDB1-CRBN E3 ubiquitin ligase complex, driving cereblon-, proteasome-, and NEDD8-activating enzyme-dependent ubiquitination and degradation, with a DC50 of approximately 30-100 pM in RS4;11 cells. BETd-260 induces cancer cell apoptosis via endogenous signaling pathways, regulates the expression of the Bcl-2 family, inhibits the oncogene c-Myc, and reduces cell viability. BETd-260 suppresses tumor growth in mouse xenograft models with good biosafety. BETd-260 can be used in research related to acute leukemia, hepatocellular carcinoma, osteosarcoma, and triple-negative breast cancer.

-
%DMSO +
Recommended: Keep the proportion of DMSO in working solution below 2% if your animal is weak.
-
%+
-
+%Tween-80 + +
-
%Saline +
The co-solvents required include: DMSO, . All of co-solvents are available by MedChemExpress (MCE). , Tween 80. All of co-solvents are available by MedChemExpress (MCE).
Working solution concentration: 0.22 mg/mL
Method for preparing stock solution: mg drug dissolved in μL DMSO. Stock solution concentration: mg/mL.
1. Take μL DMSO stock solution;
2. Add μL .
μL , mix evenly;
3. Then add μL Tween 80, mix evenly;
4. Then add μL
Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
