KIN-8194 (KIN8194) is a highly potent dual HCK and BTK inhibitor with IC50 of <0.495 and 0.915 nM, respectively.KIN-8194 demonstrated greater selectivity compared with A419259 with no KIT, RET, PDGFRA, EPHB6, or CDPK1 inhibition.KIN-8194 binds to gatekeeper residue Thr333 of HCK, but not to Cys481 of BTK.KIN-8194 shows robust inhibition of both HCK and BTK activity in MYD88-mutated cells, showed robust inhibition of HCK Tyr410 phosphorylation; inhibits the growth and survival of MYD88-mutated WM and ABC DLBCL cells.KIN-8194 overcomes ibrutinib resistance relatedto BTK Cys481Ser-expressing MYD88-mutated B-cell lymphoma cells, synergizes with the BCL-2 inhibitor venetoclax.KIN-8194 shows superior activity over ibrutinib in MYD88-mutated TMD-8 ABC DLBCL xenograft mouse model.KIN-8194 is active against ibrutinib resistance in BTK Cys481Ser -expressing ABC DLBCL xenograft mouse model.

TG-1701 (Edralbrutinib, TG1701) is a irreversible, orally available, potent and highly specific BTK inhibitor with Kd of 3 nM, IC50 of 6.7 nM, more selective than ibrutinib.TG-1701 exerts similar activity than the first-in-class BTKi ibrutinib, although with greater selectivity, in in vitro and in vivo models of B-NHL.TG-1701 impaired BCR downstream signaling in a concentration-dependent manner in IgM-stimulated cells, with maximal effects observed at 100 nM for TG-1701.TG-1701 shows mean GI50 of 6.4 uM in a set of 10 parental B-NHL cell lines (MCL cell lines GI50=4.3 uM).TG-1701 blunts Ikaros gene signature, including YES1 and MYC, in early-responder patients as well as in BTKi-sensitive B-NHL cell lines and xenografts.

XMU-MP-3 is a potent, selective, noncovalent BTK inhibitor with IC50 of 10.7 nM and 17.0 nM for BTK WT and BTK C481S mutation.XMU-MP-3 inhibited BTK‐transformed Ba/F3 cell proliferation with an IC50 of 11.4 nM, with negligible anti‐proliferative effects on parental wild‐type Ba/F3 cells (IC50>10 uM).XMU‐MP‐3 inhibited both the autophosphorylation and trans‐phosphorylation of BTK at residues Y223 and Y551, in a dose‐dependent manner in BTK‐transformed Ba/F3 cells at concentrations as low as 100 nM and completely suppressed at 1,000 nM.XMU‐MP‐3 was considerably less potent (IC50, 2,815 nM) against proliferation of BTK(T474M)‐transformed Ba/F3 cells.XMU‐MP‐3 inhibits the growth of malignant B‐cells, inhibited phosphorylation of PLCγ2 at Y1217 and Y759, substantially suppresses tumour growth in mouse xenograft models.XMU‐MP‐3 maintained inhibitory potency with an IC50 of 182.3 nM against BTK(C481S)‐Ba/F3 cells and with an IC50 of 17.0 nM in biochemical assays, suppressed ibrutinib‐resistant BTKC481S mutation in vivo.
