| Description | Tilpisertib is a serine/threonine kinase inhibitor disclosed in patent WO2017007689, designed to modulate aberrant kinase-driven signaling pathways, and is used extensively in cancer biology and signal transduction research to investigate kinase-dependent cell proliferation, survival, and resistance mechanisms, supporting preclinical evaluation of targeted therapeutic strategies. |
| In vitro | In enzymatic assays, Tilpisertib inhibited TPL2 kinase activity with an IC50 of 1.3 nM, showing selectivity against other MAPKs. In primary human monocytes and dendritic cells stimulated by LPS or TNF-α, treatment with the compound blocked the TPL2-MEK-ERK axis and suppressed the secretion of pro-inflammatory cytokines including TNF-α, IL-1β, IL-6, and IL-8 [1]. |
| In vivo | In a rat model of acute inflammation induced by LPS, oral administration of Tilpisertib reduced serum TNF-α levels with an EC50 of 667 nM. In preclinical models of colitis, inhibition of TPL2 by the compound was associated with reduced tissue pERK levels and a lower inflammatory cytokine burden, leading to an amelioration of disease pathology in the colon [1]. |
