    Abstract The utilization of machine learning has a potential to improve the environment of the development of antimicrobial agents. For practical use of machine learning, it is important that the conversion of molecules information to an appropriate descriptor because too informative descriptor requires enormous computation time and experiments for gathering data, whereas a less informative descriptor has problems in validity. In this study, we utilized a descriptor only focused on substituent. The type and the position of substituents on the molecules that have a 4-quinolone structure (11,879 compounds) were converted to the combined substituent number (CSN). While the CSN does not include information on the detailed structure, physical properties, and quantum chemistry of molecules, the prediction model constructed by machine learning of CSN indicated a sufficient coefficient of determination (0.719 for the training dataset and 0.519 for the validation dataset). In addition, this CSN can easily construct the unknown molecules library which has a relatively consistent structure by recombination of substituents (32,079,318 compounds) and screening of them. The validity of the prediction model was also confirmed by growth inhibition experiments for E. coli using the model-suggested molecules and commercially available antimicrobial agents.

    Controlled release of oxygen from myoglobin was achieved by modulating autoxidation of oxymyoglobin using ascorbic acid as a reductant by temperature variation. Long-term storage, prompt release and re-storage of oxygen were also available with this system. Furthermore, 20 nm thick nanofilms composed of oxymyoglobin and type I collagen containing ascorbic acid could successfully show autoxidation of oxymyoglobin in response to environmental temperature. The ultrathin nanofilms will be useful as oxygen-controlled releasable scaffolds for tissue engineering application.

    Liquid-ordered (Lo) phase domains, a cholesterol-rich area on lipid bilayers, have attracted significant attention recently due to their relevance to lipid rafts, the formation/collapse of which is associated with various kinds of information exchange through the plasma membrane. Here, we demonstrate that the formation/collapse of Lo phase domains in cell-sized lipo-somes, i.e., giant unilamellar vesicles (GUVs), can be controlled with bioactive plasmonic nanoparticles and light. The na-noparticles were prepared by the surface modification of gold nanorods (AuNRs) using a cationized mutant of high-density lipoprotein (HDL), which is a natural cholesterol transporter. Upon the addition of surface-engineered AuNRs to GUVs with the mixed domains of Lo and liquid-disorder (Ld) phases, the Lo domains collapsed and solid ordered (So) phase domains were formed. The reverse phase transition was achieved photothermally, with the AuNRs loaded with cholesterol. During these transitions, the AuNRs appeared to be selectively localized on the less fluidic domain (Lo or So) in the phase-mixed GUVs. These results indicate that the phase transitions occur through the membrane binding of the AuNRs followed by spontaneous/photothermal transfer of cholesterol between the AuNRs and GUVs. Our strategy to develop bioactive AuNRs potentially enables spatiotemporal control of the formation/collapse of lipid rafts in living cell.
