It is divided into pro-survival and pro-apoptotic proteins that determine cellular fate. In particular, Bax is a crucial executor of apoptosis as its activation initiates the apoptotic phenotype. Hence, targeting this protein represents an attractive therapeutic approach, which can aid in regulating apoptotic signalling and potentially contribute to the development of novel therapies against cancer and neurodegenerative diseases. Here, we introduce a digital paradigm, which relies on rational design and computer simulations to develop and validate peptide-based agents that bind to Bax, thereby inhibiting its apoptotic properties. The peptides are rationally designed and optimized to bind to Bax starting from the crystal structures of affimers in a complex with Bcl-2 proteins. Next, molecular dynamics (MD) simulations are employed to probe the stability of the Bax–peptide complexes and to estimate the binding free energies. The results show that the designed peptides bind with high affinity to Bax. Two of the designed peptides bind in the canonical hydrophobic groove (BH1 domain) of Bax and one peptide binds to the outside of the BH3 domain (α<small><sub>2</sub></small>-helix). Notably, the peptides restrict the flexibility of the α<small><sub>1</sub></small>–α<small><sub>2</sub></small> loop, modulating the trigger bottom site associated with toxicity.

The incorporation of EG inside the fibers allowed us to obtain approximately twofold improvement in maximum stress and toughness compared to pristine PS mats. Thermal camera measurement showed significant improvement in heat transport for PS–EG fibers. The heating test showed a temperature increase of ∼2.5 °C for an EG-loaded PS mat, and in the case of a resistance wire coated with a PS fiber yarn, the increase reached 17 °C. The incorporation of EG into electrospun mats enables the recovery of more energy in the form of heat by enhancing the heating of the sample through infrared radiation. The temperature increased by 2 °C for PS and by 27 °C for PS–EG, respectively.

However, its poor water solubility and rapid metabolism <em>in vivo</em> have limited its therapeutic potential, inspiring the development of delivery systems such as those based on nanotechnology. Previously, we reported that partial oxidation of the plant polyphenol quercetin (QCT) creates an amphiphilic material that self-assembles into discrete nanoparticles (NPs), either alone or with other polymers. Here we developed a nanoparticle (NP) formulation for CUR based on partially oxidized QCT (oxQCT). The NPs were co-formulated with <small>D</small>-α-tocopheryl poly(ethylene glycol) 1000 succinate (TPGS) to enhance their physicochemical properties and potentially synergize with CUR in inducing cancer cell death and alleviating inflammation. CUR was entrapped in oxQCT/TPGS NPs <em>via</em> nanoprecipitation, yielding spherical NPs (87 nm) with 72% loading efficiency, high colloidal stability, and sustained release at physiological pH. The anticancer activity of CUR NPs was evaluated in MCF-7 cells as a model breast cancer cell line, where the oxQCT/TPGS vehicle synergized with free CUR in inducing cell death and promoted its cellular uptake. In RAW 264.7 macrophages, the NPs outperformed free CUR in anti-inflammatory assays by exhibiting stronger reactive oxygen species (ROS) scavenging activities and attenuating the expression of proinflammatory cytokines. We complemented the biological assays with synchrotron-Fourier transform infrared microspectroscopy (SR-μFTIR), which provided insights into biochemical changes in the lipid and protein compositions of MCF-7 and RAW 264.7 macrophages treated with CUR NPs.
