Inflammatory and Growth Signaling Kinases – Indirect Modulation

Inflammatory and Growth Signaling Kinases – Indirect Modulation is a functional classification for therapeutic interventions that regulate key signaling cascades without directly binding to the kinase's active site. This category encompasses the modulation of pathways such as JAK/STAT, MAPK/ERK, and PI3K/AKT, which are essential for cell growth, survival, and the mediation of inflammatory cytokines (Newton & Dixit, 2012, Cold Spring Harbor Perspectives in Biology). Common strategies include the use of Hsp90 inhibitors to disrupt the folding and stability of kinase clients or the use of upstream receptor antagonists to reduce the activation of downstream kinase networks (Workman et al., 2007, Clinical Cancer Research). These approaches are primarily utilized in oncology and the treatment of chronic inflammatory diseases to circumvent resistance to direct inhibitors (Neckers & Workman, 2012, Clinical Cancer Research). However, because these kinases are involved in numerous homeostatic processes, indirect modulation can result in broad systemic toxicities, such as ocular and hepatic effects (Workman et al., 2007).
