With the recent shift toward Next Generation Risk Assessment (NGRA), which utilizes animal\u2010free alternative testing methods, the read\u2010across (RAx) approach has gained prominence. RAx relies on information from structural analogues to fill data gaps and determine a point of departure (PoD). A major challenge in RAx is assessing \u201csimilarity\u201d between the target chemical and its analogues, typically based on chemical structure, physicochemical properties, metabolic reactivity, in silico prediction profile, and biological activity. Structural similarity, often evaluated using the Tanimoto coefficient (\n                    <jats:italic>Tc<\/jats:italic>\n                    ), is a common first step, and it relies on fingerprints that convert chemical structures into machine\u2010readable formats. However, fingerprint choice significantly influences\n                    <jats:italic>Tc<\/jats:italic>\n                    calculations and subsequent analogue selection. Moreover, no guidelines exist for the use of specific fingerprints, and which fingerprint is most suitable for skin sensitization assessment by RAx has not yet been established. This study aimed to develop a novel fingerprint specifically optimized for skin sensitization assessment. A large dataset of chemicals with the murine local lymph node assay (LLNA)\u2010positive data was used for performance evaluation of various fingerprints. Our findings revealed that a novel fingerprint incorporating Protein Binding Alert\u2013based Fingerprint (PBAF) and Klekota\u2013Roth fingerprint (KRFP) features into ToxPrint outperformed others in separating suitable from unsuitable chemical pairs for RAx. This study underscores the importance of endpoint\u2010specific fingerprint development to improve analogue selection for skin sensitization risk assessments.\n
