		+	== Publication Abstract from PubMed ==
		+	Hdm2 (human MDM2) counteracts p53 function by direct binding to p53 and by ubiquitin-dependent p53 protein degradation. Activation of p53 by inhibitors of the p53-Hdm2 interaction is being pursued as a therapeutic strategy in p53 wild-type cancers. In addition, HdmX (human MDMX, human MDM4) was also identified as an important therapeutic target to efficiently reactivate p53, and it is likely that dual inhibition of Hdm2 and HdmX is beneficial. Here, we report four new X-ray structures for Hdm2 and five new X-ray structures for HdmX complexes, involving different classes of synthetic compounds. We also reveal the key additive 18-crown-ether, which we have discovered to enable HdmX crystallization and show its stabilization of various Lys-residues. In addition, we report the previously unpublished details of X-ray structure determinations for eight further Hdm2 complexes, including the clinical trial compounds NVP-CGM097 and NVP-HDM201. An analysis of all compound binding modes reveals new and deepened insights into the possible adaptations and structural states of Hdm2 (e.g. flip of F55; flip of Y67; reorientation of H96) and HdmX (e.g. flip of H55; dimer induction), enabling key binding interactions for different compound classes. In order to make comparisons easier, we have used the same numbering for Hdm2 and HdmX. Taken together, these structural insights should prove useful for the design and optimization of further selective and/or dual Hdm2/HdmX inhibitors.
