Pirtobrutinib (LOXO-305) is an advanced BTK inhibitor that displays high selectivity and operates through a non-covalent mechanism. This compound effectively inhibits various BTK C481 substitution mutations, leading to tumor regression in BTK-dependent lymphoma tumors in mouse xenograft models. Furthermore, Pirtobrutinib exhibits remarkable selectivity for BTK, with more than a 300-fold difference compared to 370 other kinases tested. Notably, at a concentration of 1 μM, Pirtobrutinib demonstrates no significant inhibition of non-kinase off-targets.

Description | Pirtobrutinib (LOXO-305) is an advanced BTK inhibitor that displays high selectivity and operates through a non-covalent mechanism. This compound effectively inhibits various BTK C481 substitution mutations, leading to tumor regression in BTK-dependent lymphoma tumors in mouse xenograft models.

Notably, at a concentration of 1 μM, Pirtobrutinib demonstrates no significant inhibition of non-kinase off-targets. |
In vitro | Pirtobrutinib potently inhibits both wild-type BTK and BTK C481S-mediated kinase activity with nanomolar potency. Pirtobrutinib strongly inhibits WT BTK (Y223) autophosphorylation with an IC50 of 3.68 nM. Pirtobrutinib inhibits BTK C481S Y223, C481T Y223, and C481R Y223 autophosphorylation with IC50s of 8.45, 7.23, and 11.73 nM, respectively[1]. |
