Summary: A comparative investigation on the electrochemical activity of substituted bromothiophenes vs bromobenzenes highlights the combined effects of the aromatic or heteroaromatic ring substituents and the sulphur atom on both the intrinsic reactivity and the reactivity in the presence of electro-catalytic effects. The presence of sulphur atom significantly promotes the process in both non-catalytic conditions and on catalytic electrodes, acting as an adsorption auxiliary. The nitrile group may also act as an additional adsorption auxiliary.

Summary: This study presents the preparation of cationic thiazole phthalocyanines (Pcs) conjugates with nitrogen doped (NGQDs) and nitrogen/sulfur co-doped (NSGQDs) graphene quantum dots (GQDs). The photo-sonodynamic combinatorial therapy (PSDT) activities of the conjugates were tested in vitro with cancer cell lines. The conjugates exhibited the production of reactive oxygen species (ROS) through the treatment technique. The Pc-GQDs generated singlet oxygen and hydroxyl radicals when exposed to light and low frequency ultrasound in PSDT. Cancer eradication was observed in vitro for the PSDT treatment using the Pc-GQDs conjugates. The NGQDs conjugates performed better in terms of ROS generation and cell eradication compared to the NSGQDs conjugates. The PSDT treatments showed increased ROS generation and cancer eradication efficiencies compared to PDT and SDT monotreatments.

Summary: This study investigates the effects of ultrasonic frequency and power on the stability, reactive oxygen species yields, and cytotoxicity activities of different substituted ionic phthalocyanines (Pcs) in sonodynamic therapy (SDT). The degradation of Pcs increases with increasing power at Par II. Two reactive oxygen species, singlet oxygen and hydroxyl radicals, were detected in ultrasound treated Pcs. Par I was chosen for SDT, photodynamic therapy (PDT), and photo-sonodynamic therapy (PSDT) due to minimal degradation of most Pcs. PSDT generally shows improved therapeutic efficacies compared to SDT and PDT mono treatments.
