Cancer encompasses a group of pathologies with common characteristics, high incidence, and prevalence in all countries. Although there are treatments available for this disease, they are not always effective or safe, often failing to achieve the desired results. This is why it is necessary to continue the search for new therapies. One of the strategies for obtaining new antitumor drugs is the use of 1,4-naphthoquinone as a scaffold in synthetic or natural products with antitumor activity. This review focuses on compiling studies related to the antitumor activity of 1,4-naphthoquinone and its natural and synthetic derivatives over the last 10 years. The work describes the main natural naphthoquinones with antitumor activity and classifies the synthetic naphthoquinones based on the structural modifications made to the scaffold. Additionally, the formation of metal complexes using naphthoquinones as a ligand is considered. After a thorough review, 197 synthetic compounds with potent biological activity against cancer have been classified according to their chemical structures and their mechanisms of action have been described.

Despite the pivotal role of cytotoxic T lymphocytes (CTLs) in anti-tumor immunity, a substantial proportion of CTL-rich hepatocellular carcinoma (HCC) patients experience early relapse or immunotherapy resistance. However, spatial immune variations impacting the heterogeneous clinical outcomes of CTL-rich HCCs remain poorly understood. Here, we compared the single-cell and spatial landscapes of 20 CTL-rich HCCs with distinct prognoses using multiplexed in situ staining and validated the prognostic value of myeloid spatial patterns in a cohort of 386 patients.

Objective: This study aims to develop a dual-ligand-modified targeted drug delivery system by integrating photosensitizers and chemotherapeutic drugs to enhance anti-glioma effects. The system is designed to overcome the blood-brain barrier (BBB) that hinders effective drug delivery, increase drug accumulation in glioma cells, and thereby enhance therapeutic efficacy.
Methods: Liposomes were prepared using the film dispersion-ammonium sulfate gradient technique, co-loading the photosensitizer indocyanine green (ICG) and the chemotherapeutic drug mitoxantrone (MTO).

Immunotherapy, particularly immune checkpoint blockade (ICB) therapies, has revolutionized oncology. However, it encounters challenges such as inadequate drug accumulation and limited efficacy against "cold" tumors characterized by lack of T cell infiltration and immunosuppressive microenvironments. Here, a controlled antibody production and releasing nanoparticle (CAPRN) is introduced, designed to augment ICB efficacy by facilitating tumor-targeted antibody production and inducing photodynamic cell death.

Copper plays an important role in the regulation of PD-L1, suggesting that reducing copper levels within tumors may enhance anti-cancer immunotherapy. Tumor microenvironment responsive copper nanodeprivator (TMECN) was developed for enhancing immunotherapy of tumor via the cross-link of mercaptopolyglycol bipyridine and dimercaptosuccinic acid modifying FePt nanoalloy using the disulfide bond. Upon entering tumor cells, the disulfide bond in TMECN is cleaved by the overexpressed glutathione, exposing abundance of sulfhydryl groups.

Dioscin is a natural plant-derived steroidal saponin that exerts antitumor effects in multiple cancers. It is widely involved in multiple apoptotic pathways and exerts its anti-tumor effects. In this study, we discovered that Dioscin treatment increased the expression of Noxa, thereby inducing the apoptosis of OSCC cells.
