ARK5 Inhibitors

ARK5 inhibitors represent a diverse class of chemicals that intricately modulate the intricate signaling pathways governed by the Atypical Kinase 5 (ARK5). Among these, staurosporine, a potent protein kinase inhibitor, directly competes with ATP binding at ARK5's catalytic site, disrupting its phosphorylation events and subsequently impacting cell survival and proliferation pathways. Sorafenib, originally a multi-kinase inhibitor, indirectly targets ARK5 by perturbing the RAF/MEK/ERK pathway, unraveling its role in inhibiting cancer cell progression. Several compounds, such as SB-203580 and SP600125, act as indirect inhibitors by targeting upstream components like p38 MAP kinase and JNK, respectively, altering ARK5 phosphorylation and influencing cellular processes. LY294002 and Rapamycin, inhibiting PI3K/AKT and mTOR pathways, indirectly modulate ARK5, shedding light on their intertwined regulatory mechanisms. Additionally, VX-745 and A-674563 selectively inhibit p38 MAP kinase and Akt1/2 kinase, respectively, impacting ARK5-mediated pathways related to inflammation and cell survival.

BAY 11-7082, a specific NF-κB inhibitor, indirectly influences ARK5 signaling, revealing the intricate connection between NF-κB activation and ARK5-regulated pathways. PD98059 and SB202190, targeting MEK and p38 MAP kinase, respectively, indirectly modulate ARK5, showcasing their roles in influencing cell cycle progression, apoptosis, and inflammation. GSK690693, a selective Akt inhibitor, uncovers the nuanced interplay between Akt and ARK5 in cellular regulation. This class of ARK5 inhibitors serves as a powerful toolkit for dissecting the complex web of signaling pathways, providing valuable insights into the biochemical tapestry woven by ARK5 in cellular homeostasis and disease progression.
