Repurposed Drugs in Gastric Cancer.

Gastric cancer (GC) is one of the major causes of death worldwide, ranking as the fifth most incident cancer in 2020 and the fourth leading cause of cancer mortality. The majority of GC patients are in an advanced stage at the time of diagnosis, presenting a poor prognosis and outcome. Current GC treatment approaches involve endoscopic detection, gastrectomy and chemotherapy or chemoradiotherapy in an adjuvant or neoadjuvant setting. Drug development approaches demand extreme effort to identify molecular mechanisms of action of new drug candidates. Drug repurposing is based on the research of

Research progress on ferroptosis in Myelodysplastic syndromes.

Myelodysplastic syndromes (MDS) are a group of malignancies characterized by clonal proliferation of hematopoietic stem cells, ineffective hematopoiesis, peripheral cytopenias, and a high risk of transformation to acute myeloid leukemia. Current therapeutic strategies for MDS have limited efficacy. Thus, identifying new therapeutic targets and prognostic biomarkers is a critical future research direction. Ferroptosis, a new type of iron-dependent programmed cell death, has become a recent hotspot in the field of oncology research. Recent results have demonstrated that iron metabolism, lipid me

Prolonged recovery time from zoledronic Acid induced acute tubular necrosis: a case report and review of the literature.

Acute tubular necrosis (ATN) due to bisphosphonates has been reported with Zoledronic acid but the time to recovery (if any) has been usually less than 4 months. Possible recovery time from ATN of any cause is usually less than 6 months. In this paper, we present the case of a 59-year-old Caucasian female with metastatic breast cancer who had received 16 monthly injections of Zoledronic acid for treatment of tumor induced hypercalcemia and developed several episodes of mild acute kidney injury which resolved by withholding treatment. Unfortunately, after the sixteenth injection, the patient ex

Current landscape and future directions of targeted-alpha-therapy for glioblastoma treatment.

Glioblastoma (GB) is the most aggressive malignancy of the central nervous system. Despite two decades of intensive research since the establishment of the standard of care, emerging strategies have yet to produce consistent satisfactory outcomes. Because of its specific localisation and intricate characteristics, GB is a uniquely regulated solid tumour with a strong resistance to therapy. Advances in targeted radionuclide therapy (TRT), particularly with the introduction of a-emitting radionuclides, have unveiled potential avenues for the management of GB. Recent preclinical and clinical stud

Progress and Future Directions with Peptide-Drug Conjugates for Targeted Cancer Therapy.

We review drug conjugates combining a tumor-selective moiety with a cytotoxic agent as cancer treatments. Currently, antibody-drug conjugates (ADCs) are the most common drug conjugates used clinically as cancer treatments. While providing both efficacy and favorable tolerability, ADCs have limitations due to their size and complexity. Peptides as tumor-targeting carriers in peptide-drug conjugates (PDCs) offer a number of benefits. Melphalan flufenamide (melflufen) is a highly lipophilic PDC that takes a novel approach by utilizing increased aminopeptidase activity to selectively increase the

Beyond Palliation: Therapeutic Applications of 153Samarium-EDTMP.

Primary and metastatic malignant bone lesions result in significant pain and disability in oncology patients. Targeted bone-seeking radioisotopes including 153Samarium ethylene-diamine-tetramethylene-phosphonic acid (153Sm-EDTMP) have been shown to effectively palliate bone pain, often when external beam radiotherapy (EBRT) is not feasible. However, recent evidence also suggests 153Sm-EDTMP has cytotoxic activity either alone or in combination with chemotherapy or EBRT. 153Sm-EDTMP may be useful as anti-neoplastic therapy apart from pain palliation in a variety of malignancies. For prostate ca

Learn from antibody-drug conjugates: consideration in the future construction of peptide-drug conjugates for cancer therapy.

Cancer is one of the leading causes of death worldwide due to high heterogeneity. Although chemotherapy remains the mainstay of cancer therapy, non-selective toxicity and drug resistance of mono-chemotherapy incur broad criticisms. Subsequently, various combination strategies have been developed to improve clinical efficacy, also known as cocktail therapy. However, conventional "cocktail administration" is just passable, due to the potential toxicities to normal tissues and unsatisfactory synergistic effects, especially for the combined drugs with different pharmacokinetic properties. The drug

Chemo-RaST with bortezomib inhibits multiple myeloma relapse.

Rationale: Multiple myeloma (MM) is a hematological malignancy with a high relapse rate that ultimately leads to patient mortality. Current therapies often fail to achieve sustained remission due to adaptation of clonally heterogeneous tumor populations. We hypothesized that Chemo-RaST, a therapeutic strategy combining bortezomib with ⁸⁹Zr-daratumumab-mediated radionuclide dynamic therapy (RaST), would synergize photophysical generation of cytotoxic reactive oxygen species (ROS) with mitochondrial ROS induction to block clonal adaptation and prevent MM relapse. Methods: We evaluated chemo-RaST

Targeted Radionuclide Therapy: Practical Applications and Future Prospects.

In recent years, there has been a proliferation in the development of targeted radionuclide cancer therapy. It is now possible to use baseline clinical and imaging assessments to determine the most effective therapy and to tailor this therapy during the course of treatment based on radiation dosimetry and tumor response. Although this personalized approach to medicine has the advantage of maximizing therapeutic effect while limiting toxicity, it can be challenging to implement and expensive. Further, in order to use targeted radionuclide therapy effectively, there is a need for multidisciplina

Recent Insights in Multi-Target Drugs in Pharmacology and Medicinal Chemistry.

Many of the drugs used in treatment today have been designed based on the "specificity paradigm". Resistance has developed against drugs designed using this approach, leading to a decrease in their effectiveness. In addition, it is well-documented in the literature that diseases with complex etiologies, such as Alzheimer's, Parkinson's, and cancer are influenced by multiple genetic and/or environmental factors. As a result, specificity paradigm is often insufficient for treating these diseases. Therefore, there is a need to develop drugs that interact with multiple targets simultaneously throu

The interplay of exercise and green tea: a new road in cancer therapy.

Exercise is one of the most important activities for every individual due to its proven health beneficials. Several investigations have highlighted the advantageous impacts of aerobic exercise, largely attributed to its capacity to enhance the body's capability to defend against threats against oxidative stress. The information currently accessible suggests that adding regular aerobic exercise to a daily routine greatly decreases the chances of developing serious cancer and passing away. An unevenness in the levels of free radicals and the body's antioxidant defenses, made up of enzyme and non

The various therapeutic applications of the medical isotope holmium-166: a narrative review.

Over the years, a broad spectrum of applications of the radionuclide holmium-166 as a medical isotope has been established. The isotope holmium-166 is attractive as it emits high-energy beta radiation which can be used for a therapeutic effect and gamma radiation which can be used for nuclear imaging purposes. Furthermore, holmium-165 can be visualized by MRI because of its paramagnetic properties and by CT because of its high density. Since holmium-165 has a natural abundance of 100%, the only by-product is metastable holmium-166 and no costly chemical purification steps are necessary for pro
