We performed molecular dynamics simulations to study the regulating ability of water chains in a Y-shaped nanochannel. It was shown that a signal at the molecular level could be controlled by two other charge-induced signals when the water chains were confined in a narrow Y-shaped nanochannel.

Abstract Polymyxins are used as last-resort antibiotics, where other treatments have been ineffectual due to antibiotic resistance. However, resistance to polymyxins has also been now reported, therefore it is instructive to characterise at the molecular level, the mechanisms of action of polymyxins. Here we review insights into these mechanisms from molecular dynamics simulations and discuss the utility of simulations as a complementary technique to  experimental methodologies.

Phthalocyanines (Pc) have received considerable attention in the design of photosensitizers for photodynamic therapy (PDT). It is of great interest to design novel Pc-based photosensitizer with improved biological efficiency, which largely relies on the understanding of the interactions of Pc with cell membranes at a molecular level. Here, via all-atom molecular dynamics simulations, we explored the interaction mechanism between a model phospholipid bilayer and three zinc Pc (ZnPc) molecules with different hydrophobicity in nature. We find that the adsorption and insertion behaviors of ZnPc molecules in the model bilayer are different due to the differing hydrophobicity and interaction patterns with phospholipids. Moreover, our simulations demonstrate that the conjunction of a ZnPc skeleton with a cholesterol moiety may reduce the intrinsic molecular rotation of ZnPc in membranes, presumably leading to an increase of the generation efficiency of reactive oxygen species for PDT. The molecular insights obtained here are likely to help improve the rational design of novel photosensitizers with enhanced cellular uptake and photocytotoxic activity.
