FKBP12 PROTAC dTAG-13

Research use only, not for human use.

FKBP12 PROTAC dTAG-13 (dTAG-13) is an in vivo-active heterobifunctional adation tag (dTAG) small molecule that engage FKBP12F36V and CRBN.

FKBP12 PROTAC dTAG-13 (dTAG-13) is an in vivo-active heterobifunctional adation tag (dTAG) small molecule that engage FKBP12F36V and CRBN, selectively degrade FKBP12F36V in a CRBN-dependent manner in cells; causes rapid degradation of nuclear and cytoplasmic FKBP12F36V fusion chimeras, and an unexpected superior antiproliferative effect of pan-BET bromodomain degradation over selective BRD4 degradation, characterize immediate effects of KRASG12V loss on proteomic signaling, and demonstrate rapid degradation in vivo.

TAG-13 (1-1000 nM; 4 hours; 293FTWT cells) treatment potently reduces FKBP12F36V-Nluc levels in 293FTWT cell, indicating the requirement of CRBN for the observed effects.Treatment of MV4;11 cells expressing BRD4(short)-FKBP12F36V with dTAG-13 leads to robust degradation of BRD4. dTAG-13 treatment leads to rapid degradation of BRD4 within one hou. dTAG-13 treatment leads to rapid and potent degradation of the BRD4 fusion chimera in the heterozygous and homozygous knock-in clones, with no effect on endogenous FKBP12WT. Western Blot Analysis Cell Line:293FTWT cells Concentration:1 nM, 10 nM, 100 nM, 1000 nM Incubation Time:4 hours Result:Potently reduced FKBP12F36V-Nluc levels in 293FTWT cell.

Following bone marrow engraftment of MV4;11 cells expressing luc-FKBP12F36V in mice, the bioluminescent signal after vehicle or dTAG-13 administration is monitored. A significant, rapid, and durable effect on bioluminescent signal is observed four hours after dTAG-13 administration, indicating effective degradation of luc-FKBP12F36V. Twenty-eight hours following the final treatment, the recovery of cellular bioluminescence to levels comparable between vehicle and dTAG-13 treatment groups is observed.
