Description:	dBET6 is a highly potent, selective and cell-permeable degrader of BET based on PROTAC, with an IC50 of 14 nM, and has antitumor activity.
In Vivo:	dBET6 (7.5 mg/kg, p.o., BID) reduces the leukemic burden in a disseminated mouse model of T-ALL[1].
In Vitro:	dBET6 is a highly potent, selective and cell-permeable degrader of BET with an IC50 of 14 nM. dBET6 (100 nM) exhibits antitumor activity against T cell acute lymphoblastic leukemia (T-ALL) lines via degradation of BRD4[1].
Animal Administration:	Mice[1] MOLT4 human T-ALL cells are intravenously injected into NSG mice (2×106 cells/mouse). Luminescence is utilized to monitor engraftment (evident at day 6), at which point mice are randomized into three cohorts that receive dBET6 (7.5 mg/kg BID, n = 8), JQ1 (20 mg/kg QD, n = 9) or vehicle (captisol, n = 9) treatment for 14 days. Survival of all three cohorts is subsequently monitored using hind limb paralysis caused by high femoral leukemic burden as a defined endpoint. SUPT11 human T-ALL cells (mCherry+ and Luciferase+) are intravenously injected into NSG mice (2.52×106 cells/mouse). Luminescence is used to monitor successful engraftment, occurring 10 days after injection. At this point, animals are randomized into three cohorts that receive dBET6 (7.5 mg/kg BID, n = 7), JQ1 (7.5 mg/kg BID, n = 7) or vehicle (captisol, n = 7) treatment for 18 days. Treatment burden is assessed via total body luminescence imaging as well as by bone marrow infiltration by mCherry+ T-ALL cells[1].

Cat. No.	Product name	Field of application
DC67177	BTK-IN-29	BTK-IN-29 (compound 14) is an inhibitor of Btk.
DC65810	KT-333	KT-333 is a first-in-class molecular glue that induces selective degradation of STAT3 via the ubiquitin-proteasome system by simultaneously engaging STAT3 and the VHL E3 ligase. This novel mechanism enables potent STAT3 depletion with minimal off-target effects, demonstrating strong anti-tumor activity in hematologic malignancies.
DC55003	XY028-140 (MS140)	XY028-140 (MS-140) is a potent and selective PROTAC-based CDK4/CDK6 kinase degrader. XY028-140 specifically inhibits RB-E2F signaling and reduces CDK4 and CDK6 protein levels in a dose- and time-dependent manner in vitro. In addition, XY028-140 can degrade its targets by linking them with ubiquitin-proteasome mechanism. Further, the degradation of CDK4/6 protein by XY028-140 is specifically mediated by CRBN. Therefore, XY028-140 effectively and selectively inhibits and degrades CDK4/6 kinase by targeting CDK4/6 kinase in CDK4/6i-S (CDK4/6 inhibitor-sensitive) tumor cells to the CRL4-CRBN-E3 ubiquitin complex. Compared with CDK6 wild-type cells, XY028-140 treatment of cells expressing wild-type or mutation-activated CDK6 resulted in a more effective degradation of CDK6 (S178P).
DC74522	WDR5 PROTAC MS40	MS40 is a cereblon (CRBN)-based proteolysis targeting chimera (PROTAC) degrader of the onco-target WD repeat domain 5 (WDR5) [1]. WDR5 is an integral component of the MLL/KMT2A lysine methyltransferase protein complex. The WDR5-binding component of MS40 is the selective inhibitor OICR-9429, and the CRBN-targeting moiety is the immunomodulatory drug pomalidomide. MS40 promotes degradation of WDR5 and the pomalidomide transcription factor neo-substrates IKZF1 and IKZF3.
DC12022	dBET6	dBET6 is a highly potent, selective and cell-permeable degrader of BET with an IC50 of 14 nM, and has antitumor activity.
