The structural characterization is reported of the supra-molecular complex between the tetra-quinoxaline-based cavitand 2,8,14,20-tetra-hexyl-6,10:12,16:18,22:24,4-,'-tetra-kis-(quinoxaline-2,3-di-yl)calix[4]resorcinarene () with benzo-nitrile. The complex, of general formula CHNO·2CHN, crystallizes in the space group with two independent mol-ecules in the asymmetric unit, displaying very similar geometrical parameters. For each complex, one of the benzo-nitrile mol-ecules is engulfed inside the cavity, while the other is located among the alkyl legs at the lower rim. The host and the guests mainly inter-act through weak C-H⋯π, C-H⋯N and dispersion inter-actions. These inter-actions help to consolidate the formation of supra-molecular chains running along the crystallographic axis direction.

Uncontrollable cancer cell growth is characterized by the maintenance of cellular homeostasis through the continuous accumulation of misfolded proteins and damaged organelles. This review delineates the roles of two complementary and synergistic degradation systems, the ubiquitin-proteasome system (UPS) and the autophagy-lysosome system, in the degradation of misfolded proteins and damaged organelles for intracellular recycling. We emphasize the interconnected decision-making processes of degradation systems in maintaining cellular homeostasis, such as the biophysical state of substrates, receptor oligomerization potentials (e.
