Design, Synthesis, and Preliminary Studies of Spiro-isoxazoline-peroxides against Human Cytomegalovirus and...

Area of Science:

• * Organic Chemistry
• * Medicinal Chemistry
• * Virology

Background:

• * The link between glioblastoma (GBM) and human cytomegalovirus (HCMV) is a long-standing area of research for novel therapeutic strategies.
• * Peroxides, both natural and synthetic, have historically shown potential as antiviral and anticancer agents.
• * Developing new treatments for GBM and HCMV remains a critical unmet medical need.

Purpose of the Study:

• * To synthesize and evaluate a novel class of spiro-isoxazoline peroxides for biological activities.
• * To investigate the in vitro antiviral efficacy against HCMV.
• * To assess the antiproliferative effects on a human glioblastoma cell line (GBM6).

Main Methods:

• * Synthesis of a novel series of peroxides incorporating a spiro-isoxazoline scaffold.
• * In vitro antiviral assays against HCMV.
• * In vitro antiproliferative assays using the GBM6 glioblastoma cell line.

Main Results:

• * Compound 13m exhibited moderate in vitro antiviral activity against HCMV with an IC50 of 19 μM.
• * Compound 13m demonstrated significant antiproliferative activity against the GBM6 glioblastoma cell line with an IC50 of 10 μM.
• * The study identified a promising lead compound with dual potential against HCMV and GBM.

Conclusions:

• * The combination of isoxazoline and peroxide moieties in novel compounds is a viable strategy for drug discovery.
• * Compound 13m represents a potential starting point for developing new therapeutic agents targeting both HCMV infection and glioblastoma.
• * Further research into this class of compounds could lead to effective treatments for HCMV-associated GBM.
