However, traditional drug discovery methods for developing AXL inhibitors are resource-intensive, timeconsuming, and often fail to provide detailed insights into molecular determinants of potency.

SHAP analysis identified critical molecular |\n| Cancer therapeutics | features, such as RNCG and TopoPSA(NO), as key contributors to inhibitor potency, providing interpretable insights into structure-activity relationships. These findings highlight the potential of machine learning to accelerate the identification and optimization of AXL inhibitors, bridging the gap between computational predictions and rational drug design and paving the way for effective cancer therapeutics. |\n|  | Copyright: © 2025 by the authors.

Introduction  \nAXL, a receptor tyrosine kinase, is critical in various physiological and pathological processes, including cell survival, proliferation, migration, and immune response [1] . Overexpression or dysregulation of AXL has been implicated in the progression of several cancers,  \nincluding hepatocellular carcinoma [2], non-small cell lung cancer [3], and breast cancer [4] . It is critical in promoting metastasis, therapy resistance, and poor patient prognoses. As a result, AXL has emerged as a promising therapeutic target in cancer drug discovery, with inhibitors of AXL tyrosine kinase showing potential  \nFigure 1.
