PROTAC BTK Degrader-6
Based on 1 Customer Validation
PROTAC BTK Degrader-6 is an orally active PROTAC-based BTK degrader with a DC50 of 3.18 nM. PROTAC BTK Degrader-6 induces BTK degradation via proteasomal degradation, ubiquitination, and CRBN ligase recruitment pathways. PROTAC BTK Degrader-6 inhibits NF-κB activation, mRNA expression of IL-1β and IL-6, as well as the secretion of pro-inflammatory cytokines. PROTAC BTK Degrader-6 reduces inflammatory responses in a zymosan-induced mouse model of peritonitis. PROTAC BTK Degrader-6 can be used in peritonitis-related research.

PROTAC BTK Degrader-6 (compound 15) (0.15-10000 nM; 4-72 h) potently degrades BTK in Ramos cells, with a DC50 of 3.18 nM and a maximum degradation rate of 99.90%. The degradation effect persists for at least 48 h after washout, and the agent functions through a proteasome-dependent pathway that relies on the binding of BTK and CRBN[1].
PROTAC BTK Degrader-6 (0.1-1000 nM; 24 h) potently degrades BTK in Mino cells, with a DC50 of 7.07 nM and a maximum degradation rate of 99.99%[1].
PROTAC BTK Degrader-6 (2.5-20 μM; 24 h) does not reduce the viability of RAW264.7 cells after 24 h of treatment at concentrations up to 10 μM[1].
PROTAC BTK Degrader-6 (0.1-10 μM; 1 h pre-treatment, followed by 24 h co-incubation with LPS) dose-dependently degrades BTK and inhibits NF-κB activation in LPS-stimulated RAW264.7 cells by reducing the phosphorylation levels of BTK and p65, as well as the phosphorylation and degradation of IκB-α[1].
PROTAC BTK Degrader-6 (0.1-10 μM; 2 h pre-treatment followed by 3 h LPS stimulation for RT-qPCR; co-incubation with LPS for ELISA) dose-dependently inhibits the mRNA expression and protein secretion of pro-inflammatory cytokines IL-1β and IL-6 in LPS-stimulated RAW264.7 cells[1].
