Special Issue Information

Dear Colleagues,

This Special Issue highlights cutting-edge organic and material chemistry research, focusing on the synthesis, detailed characterization, molecular informatics, and biological evaluation of bioactive molecules and functional materials. We invite contributions that delve into novel synthetic methodologies, advanced structural and spectroscopic analysis, and computational techniques such as molecular docking and predictive modeling to optimize biological interactions. This Special Issue also emphasizes the in vitro and in vivo evaluation of organic compounds and functional materials, with a particular interest in applications across fields such as medicine, agriculture, environmental science, and advanced materials.

Topics of interest include innovations in molecular design, computational strategies for bioactivity prediction, quantitative structure–activity relationships (QSARs) analysis, and sustainable chemistry practices. This multidisciplinary approach aims to bridge organic synthesis with real-world applications, fostering advances that support sustainable and health-focused solutions. We welcome contributions from researchers who wish to showcase novel insights and trends that underscore the vital role of organic molecules and materials in scientific and industrial progress.

Abstract
Resveratrol is one of the most extensively studied natural products due to its pleiotropic health benefits. However, its low water solubility and limited stability hinder its application in the nutraceutical, cosmetic, and pharmaceutical sectors.

Resveratrol is one of the most extensively studied natural products due to its pleiotropic health benefits. However, its low water solubility and limited stability hinder its application in the nutraceutical, cosmetic, and pharmaceutical sectors. In this work, we investigated the ability of a cationic mono-choline-β-cyclodextrin derivative to complex trans-resveratrol. The complex was prepared using a phase solubility method without using organic solvents and was found to be stable after freeze-drying. The complex was characterized by a phase solubility study, NMR spectroscopy, and molecular modeling simulations, which revealed a 1:1 stoichiometry, a stability constant of 2051 M−1 (KC), and structural details. Complexation improved resveratrol’s solubility and dissolution rate, reduced its photoinduced trans-to-cis isomerization, and preserved its radical scavenging activity. The wound-healing activity of the complex was demonstrated via in vitro experiments on human keratinocyte cells. Full article

Innovative functional materials integrating host–guest complexes in cryogels offer promising applications in topical drug delivery, enhancing drug solubility and stability. In this study, we designed and developed a cryogel-based patch for acne treatment by polymerizing an acrylate-functionalized γ-cyclodextrin (γ-CD) and trimethoprim (TMP) inclusion complex with [2-(acryloyloxy)ethyl]trimethylammonium chloride (AETMA) at low temperatures. A multistep workflow was applied to synthesize the inclusion complex via mortar-assisted kneading, followed by cryogel formulation through radical cryopolymerization. The resulting hybrid system leverages the cationic nature of AETMA to promote adhesion and electrostatic interactions with the skin surface. At the same time, γ-CD serves as a drug reservoir, facilitating sustained release of the drug. The system was characterized by FT-IR, TGA, and SEM analyses. In vitro release studies demonstrated a sustained TMP release profile, best described by the Korsmeyer–Peppas diffusion model. Antibacterial assays confirmed the system’s effectiveness against Staphylococcus aureus, supporting its potential for localized and prolonged acne treatment. Moreover, cytocompatibility tests demonstrated that the formulation is biocompatible, further validating its suitability for topical application. Full article
