KBD-1
KBD-1 is a muscle-specific BRD4 PROTAC degrader with human KDs of 27.04 nM and 37.36 µM against BRD4 and KLHL4L, respectively. KBD-1 recruits the muscle-specific E3 ligase KLHL41, mediating Cullin-RING ligase (CRL)-dependent ubiquitination and proteasome degradation of BRD4. KBD-1 can be used for the research of myosarcoma.
(Pink: BRD4 ligand (HY-78695); Blue: KLHL41 ligand (HY-184150); Black: linker).

BRD4 |
KBD-1 directly interacts with purified recombinant KLHL41 protein with a KD of 37.36 µM[1].
KBD-1 (20 μM; 12 h) completely degrades BRD4 in RH30 human rhabdomyosarcoma cells[1].
KBD-1 (20 μM) induces BRD4 degradation in RH30 human rhabdomyosarcoma cells via Cullin-RING ligase (CRL)-mediated ubiquitination and proteasomal degradation[1].
KBD-1 (20 μM; 24 h) induces BRD4 degradation specifically in RD and RH30 human rhabdomyosarcoma cells (KLHL41-expressing) but not in OV90, A549, SW480, or HeLa non-muscle cancer cell lines[1].
KBD-1 (40 μM; 24 h) induces cytotoxicity specifically in RD and RH30 human rhabdomyosarcoma cells but not in OV90, A549, SW480, or HeLa non-muscle cancer cell lines, with an IC50 of 20 μM in myosarcoma cells[1].
KBD-1 (20 μM; 12 h)-induced BRD4 degradation in RH30 human rhabdomyosarcoma cells is dependent on KLHL41 expression[1].
KBD-1 (20 μM; 12 h) induces BRD4 degradation in HeLa human cervical adenocarcinoma cells only when KLHL41 is overexpressed, confirming KLHL41-dependent activity[1].
KBD-1 induces BRD4 degradation in differentiated C2C12 mouse myocytes (high KLHL41 expression) but not in undifferentiated C2C12 myoblasts (low KLHL41 expression)[1].
