Hexagonal boron nitrides (hBNs) show potential in reducing drug-induced cellular stress. This study found hBNs decrease oxidative stress without harming cells, suggesting therapeutic applications.
Area of Science:
- Biomaterials Science
- Nanotechnology
- Cellular Biology
Background:
- Drugs used for treating disorders can cause molecular stress and side effects on healthy cells.
- Investigating novel therapeutic agents is crucial to mitigate drug-induced cellular damage.
Purpose of the Study:
- To evaluate hexagonal boron nitrides (hBNs) and boric acid (BA) as agents to relieve drug-induced cellular stress.
- To assess the cytotoxicity and cellular effects of hBNs and BA.
Main Methods:
- Cytotoxicity assessment of hBNs and BA on mouse hippocampal cells (mHippo E-14) across various concentrations and time points (24h, 72h).
- Evaluation of cell cycle, reactive oxygen species (ROS) generation, cell death mechanisms, and apoptotic body formation.
- Treatment of doxorubicin (DOX)-induced oxidative stress in cells with hBNs and BA.
Main Results:
- hBNs demonstrated a decrease in oxidative stress at non-toxic concentrations.
- Boric acid (BA) and hBNs showed varying cytotoxicity depending on concentration and exposure duration.
- hBNs mitigated doxorubicin-induced oxidative stress in cellular models.
Conclusions:
- hBNs exhibit potential as a therapeutic agent to reduce drug-induced cellular stress and oxidative damage.
- The slow degradation feature of hBNs supports their investigation for mitigating adverse effects of chemotherapy and other toxic drugs.
- hBNs may offer new therapeutic strategies for neurological disorders and cancer treatment by reducing drug toxicity.

Alcohols from Carbonyl Compounds: Reduction
Catalytic hydrogenation is similar to the reduction of an alkene or alkyne by adding H2 across the pi bond in the presence of transition metal catalysts like Raney Ni, Pd–C, Pt, or Ru. Aldehydes and ketones can be reduced by this method, often under mild to moderate heat (25–100°C) and...
