“…It is important to note that slight differences in structure may be associated with large changes in activity and toxic effects, this is often termed an “activity cliff” ( Maggiora, 2006 ). Such minor differences in structure may affect reactivity, and hence endpoints such as skin sensitisation ( Pestana et al, 2022 ) or receptor binding, notable for reproductive effects ( Mori et al, 2018 ). To be accurate, structural alerts must encode this information to avoid over-prediction.…”

“…Here rules and definite criteria are needed to then exclude a substance from a group. A process to determine whether or not the properties of chemicals within a category fall within an appropriate domain from which a reliable read-across prediction can be made was introduced by Pestana et al [154] Prioritization has been used in the past to find less hazardous substances with the same or similar technical applicability, for example synthetic vitreous fibers instead of asbestos (Section 2.1), with this principle being a central element of CSS: finding the "right" chemicals by SSbD. [155] Unfortunately, regrettable substitutions do occur if evaluations are not done meticulously and with use of good science-backed knowledge; [79] one example is the substitution of dichloromethane (a suspected carcinogen, category 2) as a brake cleaner by the neurotoxic n-hexane.…”

“…Hier werden dann Regeln und eindeutige Kriterien benötigt, um einen Stoff aus einer Gruppe auszuschließen. Pestana et al [154] . stellten ein Verfahren vor, mit dem festgestellt werden kann, ob die Eigenschaften von Stoffen innerhalb einer Kategorie in einen geeigneten Bereich fallen, aus dem eine zuverlässige Vorhersage gemacht werden kann.…”

“…Die in der Vergangenheit verwendeten Methoden sind jedoch möglicherweise für zukünftige Zwecke nicht mehr geeignet. [154] stellten ein Verfahren vor, mit dem festgestellt werden kann, ob die Eigenschaften von Stoffen innerhalb einer Kategorie in einen geeigneten Bereich fallen, aus dem eine zuverlässige Vorhersage gemacht werden kann. Priorisierung wurde in der Vergangenheit eingesetzt, um weniger gefährliche Stoffe mit gleicher oder ähnlicher technischer Eignung zu finden, z.…”
