Rocbrutinib
Based on 1 Customer Validation
Rocbrutinib is an orally available, highly selective Bruton's tyrosine kinase (BTK) inhibitor, with an IC50 of 0.11 nM against wild-type BTK and an IC50 of 1.0 nM against C481S-mutated BTK. Rocbrutinib reduces the viability of leukemia cells, induces cytotoxicity and inhibits cell migration. Rocbrutinib can be used in research related to chronic lymphocytic leukemia, non-Hodgkin's lymphoma and mantle cell lymphoma.

Biological Activity
Rocbrutinib (LP-168) is a highly selective BTK inhibitor with nanomolar enzymatic potency against both wild-type and BTKC481S[1].
Rocbrutinib (LP-168) (increasing concentrations; 2 hours) inhibits BCR signaling in primary CLL B cells, reducing phosphorylation of BTK and PLCγ2 significantly[1].
Rocbrutinib (LP-168) (2 hours) reduces the migration capacity of primary CLL B cells towards CXCL12 and CXCL14 by over 50%[1].
Rocbrutinib (LP-168) (48 hours) induces dose-dependent cytotoxicity in primary CLL B cells, both in the absence and presence of HS-5 stromal cell support[1].
Rocbrutinib (LP-168) reduces CCL3 and CCL4 chemokine production by primary CLL B cells by 93% each[1].
Rocbrutinib (LP-168) (1 μM) induces modest cytotoxicity and marked reduction of CCL3 and CCL4 production in TMD8 cells expressing BTKT474I[1].
Rocbrutinib (LP-168) induces cytotoxicity and marked reduction of CCL3 and CCL4 production in TMD8 cells expressing BTKC481S[1].
Rocbrutinib forms a covalent bond to BTK's C481 residue and engages in hydrogen bonding with M477, D539, and K430 within the ATP-binding site[2].
Rocbrutinib binds WT BTK (IC50 = 4.7 nM), C481S BTK (IC50 = 49.7 nM), T474I BTK (IC50 = 13.1 nM), and L528W BTK (IC50 = 80.4 nM) with low nanomolar affinity in a NanoBRET assay[2].
Rocbrutinib exhibits nanomolar binding potency to full-length WT BTK and BTK with BTKC481S, BTKV416L, BTKM437R, or BTKL528W mutations in HEK293T cells in an FPCBA[2].
Rocbrutinib inhibits viability of TMD8 cells expressing WT, C481S, T474I, or L528W BTK with nanomolar GI50 potency[2].
Rocbrutinib potently inhibits BCR signaling in TMD8 cells expressing WT, C481S, T474I, or L528W BTK, reducing CCL3/CCL4 cytokine production by >96% and blocking phosphorylation of BTK, PLCγ2, ERK, and AKT[2].
Rocbrutinib (500 nM; 2 hours) inhibits BCR signaling in primary CLL B-cells (including those with BTKC481S), reducing phosphorylation of BTK by 98.9%, PLCγ2 by 85.6%, ERK by 59.3%, and AKT by 68.9%[2].
