Abstract

Pancreatic ductal adenocarcinoma (PDAC) has limited treatment options, underscoring the urgent need for developing new therapies. The upregulation of TBK1 activity plays a crucial role in multiple pancreatic cancer-related signaling pathways, suggesting that inhibiting the kinase activity of TBK1 could be a promising strategy. Herein, we discovered a novel TBK1 inhibitor, LIB3S0280, using a structure-based virtual screening (SBVS) strategy. In the anti-proliferative and viability assays, LIB3S0280 showed significant inhibition against pancreatic cancer cell lines that highly express TBK1 with the GI₅₀ values of 2.24 and 4.71 μM and IC₅₀ values of 6.64 and 10.98 μM at 96 h. For the downstream targets, LIB3S0280 can inhibit TBK1 downstream signaling by decreasing the phosphorylation of IκBα and AKT better than a known TBK1 inhibitor, BX-795. Furthermore, PDAC cells were arrested in G₂/M and underwent apoptosis or senescence with the treatment of LIB3S0280. These findings suggest that TBK1 inhibitor LIB3S0280 has great potential as a lead compound in the further development of a novel treatment for PDAC.
