Synthesis and Biological Evaluation of Novel Imidazole Derivatives as Antimicrobial Agents.

Imidazole derivatives are considered potential chemical compounds that could be therapeutically effective against several harmful pathogenic microbes. The chemical structure of imidazole, with a five-membered heterocycle, three carbon atoms, and two double bonds, tends to show antibacterial activities. In the present study, novel imidazole derivatives were designed and synthesized to be evaluated as antimicrobial agents owing to the low number of attempts to discover new antimicrobial agents and the emerging cases of antimicrobial resistance.

Enhancing the Antiproliferative Activity of Perillyl Alcohol against Glioblastoma Cell Lines through Synergistic Formulation with Natural Oils.

Background: Due to its volatility, photostability, and gastrointestinal toxicity, Perillyl Alcohol (POH), a monoterpenoid component of various plant species, is a chemotherapeutic drug with insufficient efficacy. Many naturally occurring bioactive compounds have well-known antiproliferative properties, including sefsol, jojoba, tea tree, and moringa oils.

Objective: This study sought to develop an oil-based Self Nanoemulsifying Drug Delivery System (SNEDDS) using tween 80 as the surfactant and Dimethyl Sulfoxide (DMSO) or Polyethylene Glycol (PEG) 400 as the cosurfactant; the oils were used in a range of 10-20% to boost POH's anticancer efficacy.

Incorporation of Perillyl Alcohol into Lipid-Based Nanocarriers Enhances the Antiproliferative Activity in Malignant Glioma Cells.

Perillyl alcohol (PA), a naturally existing monocyclic terpene related to limonene, is characterized by its poor aqueous solubility and very limited bioavailability. Its potential anti-cancer activity against malignant glioma has been reported. The aim was to develop PA-loaded lipid-based nanocarriers (LNCs), and to investigate their anti-cancer activity against two different brain cell lines.

GL67 lipid-based liposomal formulation for efficient siRNA delivery into human lung cancer cells.

The efficient delivery of small interfering RNA (siRNA) to the targeted cells significantly affects the regulation of the overexpressed proteins involved in the progression of several genetic diseases. SiRNA molecules in naked form suffer from low internalization across the cell membrane, high susceptibility to degradation by nuclease enzyme and low stability, which hinder their efficacy. Therefore, there is an urge to develop a delivery system that can protect siRNA from degradation and facilitate their uptake across the cell membrane.
