Fully automated radiosynthesis of [18F]mG4P027 for mGluR4 imaging

Fully automated radiosynthesis of [18F]mG4P027 for mGluR4 imaging

The radiosynthesis of some radiotracers, such as [18F]mG4P027, requires a challenging two-step labeling process. In this study, we successfully automated this process using an FX2N module, achieving a high yield of radiolabeled [18F]mG4P027 with high purity suitable for human studies.

An in situ self-assembled peptide derivative for inhibition of glutathione synthesis and selective enhancement of tumor radiotherapy

An in situ self-assembled peptide derivative for inhibition of glutathione synthesis and selective enhancement of tumor radiotherapy

Inhibition of glutathione (GSH) synthesis in cancer cells considerably improves the efficacy of reactive oxygen species-related tumor therapy. Herein, a novel in situ self-assembling peptide derivative (Nano-BSO@ in situ) is constructed for the inhibition of GSH synthesis and selective enhancement of ROS-related radiotherapy treatment of tumor cells with high alkaline phosphatase expression.

Molecular imaging for cancer immunotherapy

Molecular imaging for cancer immunotherapy

The efficacy of immunotherapy is often affected by tumor heterogeneity. The noninvasive molecular imaging can also monitor the treatment response of tumors, and achieve personalized response assessment, which may lead to perfected clinical management, development of individualized treatments, and reliable prognosis at last. This article reviews recent researches in immunotherapy response assessment, immune T cell imaging, immune checkpoint imaging, and radiomics/radiogenomics in immunotherapy. So far, these studies are primarily exploratory preclinical imaging, and preliminary results indicate that biomarker molecular imaging may play a role in the assessment of immunotherapy, and the principle of selecting patients for immunotherapy based on imaging results is feasible.

A review of biomodified or biomimetic polymer dots for targeted fluorescent imaging and disease treatments

A review of biomodified or biomimetic polymer dots for targeted fluorescent imaging and disease treatments

Fluorescent (FL) semiconducting polymer dots (Pdots) are attracting extensive attention as promising theranostic agents due to their tunable optical properties, high quantum yield, abundant functional groups, exceptional photostability, and excellent biocompatibility. Meanwhile, biomimetic Pdots can exhibit their capability in targeted imaging of lesion and increased efficacy for disease treatment. This mini-review will inspect the recent advances in the design and functionalization strategies of biomodified and biomimetic Pdots for enhanced disease theranostics. Therefore, this short review summarize the recent advances in biomodified and biomimetic Pdots for FL imaging in disease theranostics. Also demonstrate how these Pdots functionalization procedures can affect their photophysical properties, further improving their FL molecular imaging capability and enhancing the efficacy of disease treatment. In particular, these biomodified and biomimetic Pdots will open a new avenue for their potential biomedical applications and clinical translation.
