| Sonodynamic therapy (SDT) is an emerging, non-invasive treatment modality that employs ultrasound energy in conjunction with sonosensitizers to induce cytotoxicity in target tissues. A key mechanism by which SDT exerts its therapeutic effects is through the generation of reactive oxygen species (ROS). Also known as high-intensity focused ultrasound (HIFU) SDT relies on the ultrasound-triggered activation of sonosensitizers (similar in concept to photosensitizers used in photodynamic therapy). When activated by ultrasound, these compounds undergo energy transitions that lead to the production of ROS, such as singlet oxygen and free radicals. -Advantages of SDT include its non-invasive nature, deep tissue penetration of ultrasound, and the ability to target localized areas with high precision. -Challenges remain in precisely controlling ROS production and ensuring that the resulting oxidative stress is sufficient to induce cell death in tumor cells without overwhelming damage to surrounding normal tissues. Sonosensitizers: – Hematoporphyrin Derivative (HPD) and Photofrin – Protoporphyrin IX (PpIX) – Chlorin e6 (Ce6) – Phthalocyanine compounds – Titanium Dioxide (TiO2) Nanoparticles – Other metallic or semiconductor nanoparticles, sometimes functionalized or loaded with traditional sensitizer molecules (e.g., gold nanoparticles, copper-cysteamine), have been explored to enhance ROS production and improve tumor targeting. – Curcumin, derived from turmeric, has been shown in several studies to exhibit sonosensitizing properties. – Under ultrasound activation, quercetin may act as a sonosensitizer, increasing ROS generation and contributing to cancer cell apoptosis. US frequency range of 150 kHz–3 MHz, irradiation dose of 2–3 W cm−2, and the actuation duration range of 1–20 min are used for SDT research https://can-amhifu.com/ https://canadaclinicsupply.com/product/soundcare-plus-professional-dual-ultrasound-device-by-roscoe/ https://physiostore.ca/product-category/therapeutic-modalities/therapeutic-ultrasound/clinical-ultrasound-systems/ https://physiostore.ca/richmar-home-ultrasound-2000-2nd-edition/ -SDT is a pro-oxidant modality → strong antioxidants could theoretically reduce efficacy if present at high tissue levels (same logic as PDT), but this is highly protocol- and sensitizer-dependent. -Hypoxia can blunt ROS-based killing; strategies sometimes include oxygenation, microbubbles, or vascular modulation.

| The proteins of BCL-2 family are classified into three subgroups, i.e., the anti-apoptotic/pro-survival proteins represented by BCL-2 and BCL-XL, the pro-apoptotic proteins represented by BAX and Bak, and the pro-apoptotic BH3-only proteins represented by BAD and BID. Since the expression of Bcl-2 protein in tumor cells is much higher than that in normal cells, inhibitors targeting it have little effect on normal cells. |
