This paper aimed to develop two types of support materials with a mesoporous structure mobile crystalline matter (known in the literature as MCM, namely MCM-41 and MCM-48) load them gallic acid. Soft templating methodology was chosen for preparation structures-the cylindrical micelles certain structural characteristics being formed due hydrophilic hydrophobic intermolecular forces which occur between molecules surfactants (cetyltrimethylammonium bromide-CTAB) when minimal micellar ionic concentration is reached. These supports were loaded acid using three different MCM-gallic ratios (1:0.41; 1:0.82 1:1.21)-and their characterizations by FTIR, SEM, XRD, BET drug release performed. It worth mentioning that loading carried out vacuum-assisted methodology: are firstly kept under vacuum at ~0.1 barr 30 min followed addition polyphenol solutions. The solutions adapted such final volume covered wet and-in this case-upon reaching normal atmospheric pressure, solution pushed inside pores, thus polyphenols mainly pores. Based on SBET data, it can be seen specific surface area decreased considerably increasing ratio acid; 3.07 4.25 times MCM-48, respectively. sample highest content further evaluated from biological point view, alone or association amoxicillin administration. As expected, MCM-48 not protective against infections-but, acid, potentiated inhibition recorded tested gram-negative bacterial strains.

Targeted protein degradation (TPD) strategies offer a significant advantage over traditional small molecule inhibitors by selectively degrading disease-causing proteins. While molecules can lead to recurrence and resistance due compensatory pathway activation, TPD addresses this limitation promoting degradation, thereby reducing the likelihood of long-term. Despite these benefits, bifunctional face challenges such as low solubility, poor bioavailability, limited tumor specificity. In study, we developed polymer-based nanoparticles that combine with nanotechnology through hydrophobic tagging method. Hydrophobic polymer-tagged facilitate targeted incorporating polymers mimic residues in misfolded This system combines delivery capabilities within platform, inducing while improving stability, targeting.

Immunotherapy has revolutionized cancer treatment, dramatically improving survival rates of melanoma and lung patients. Nevertheless, immunotherapy is almost ineffective against ovarian (OC) due to its cold tumor immune microenvironment (TIM). Many traditional medications aimed at remodeling TIM are often associated with severe systemic toxicity, require frequent dosing, show only modest clinical efficacy. In recent years, emerging nanomedicines have demonstrated extraordinary immunotherapeutic effects for OC by reversing the because physical biochemical features can all be harnessed obtain optimal expected tissue distribution cellular uptake.
