Children from the abaucin-parent were first generated by maximizing affinities (minimizing docking-scores) as the unique criteria to explore the molecular characteristics of any possible predictions. After eliminating those children predicting known DW toxicities, the highest children affinities were found at mean molecular weights of 476 ±52 g/mol and mean logP hydrophobicities of 6.1 ±1.6 (Figure ).
