Introduction: Colorectal cancer (CRC) is characterized by an extremely high mortality rate, mainly caused by the high metastatic potential of this type of cancer. To date, chemotherapy remains the backbone of the treatment of metastatic colorectal cancer. Three main chemotherapeutic drugs used for the treatment of metastatic colorectal cancer are 5-fluorouracil, oxaliplatin and irinotecan which is metabolized to an active compound SN-38.

Resistance of cancer cells, especially breast cancer, to therapeutic medicines represents a major clinical obstacle that impedes the stages of treatment. Carcinoma cells that acquire resistance to therapeutic drugs can reprogram their own metabolic processes as a way to overcome the effectiveness of treatment and continue their reproduction processes. Despite the recent developments in medical research in the field of drug resistance, which showed some explanations for this phenomenon, the real explanation, along with the ability to precisely predict the possibility of its occurrence in breast cancer cells, still necessitates a deep consideration of the dynamics of the tumor's response to treatment.

The limited selectivity and high systemic toxicity of traditional chemotherapy hinder its efficacy in treating diffuse large B-cell lymphoma (DLBCL). The combination of sonodynamic therapy (SDT) with chemotherapy has emerged as a novel strategy for cancer treatment, aiming to improve therapeutic outcomes and reduce systemic toxicity. However, challenges such as elevated drug clearance rates and non-selecitivity remain to be resolved.

DNA-based nanomaterials have attracted increasing attention over the past decades due to their incomparable programmability and functionality. In particular, dendritic DNA nanostructures are ideal for constructing drug carriers due to their highly branched structure. In this study, an intelligent drug delivery system was constructed based on DNA dendrimers, in which the DNA duplexes were utilized for simultaneously loading both hydrophilic and hydrophobic small molecule drugs.

In this study, a novel inhibitor of ERCC1/XPF heterodimerization, A4, was used as an inhibitor of repair for DNA damage by platinum-based chemotherapeutics. Nano-formulations of A4 were developed, using self-assembly of the following block copolymers: methoxy-poly(ethylene oxide)-block-poly(α-benzyl carboxylate-ε-caprolactone) (PEO-b-PBCL), methoxy-poly(ethylene oxide)-block-poly(ε-caprolactone) (PEO-b-PCL), or methoxy-poly(ethylene oxide)-block-poly (D, L, lactide) (PEO-b-PDLA 50-50). The nano-formulations were characterized for their average diameter, polydispersity, morphology, A4 encapsulation and in vitro release.
