Stimulator of interferon genes (STING) plays a vital role in the human innate immune system. Aberrant expression of STING has been proven to be associated with several diseases, such as STING-associated vasculopathy with onset in infancy, Aicardi-Goutieres syndrome, and systemic lupus erythematosus. Therefore, inhibition of the STING signaling pathway can also be expected to provide effective therapeutic strategies for treating specific inflammatory and autoimmune diseases. However, the development of STING inhibitors is still in its infancy. There is still a need for additional efforts toward the discovery of new skeletons and more potent lead compounds for STING inhibition to meet clinical demand. In this review, we provide a summary of STING inhibitors, classified by different structural skeletons, reported in patents published from 2019 to July 2022. In addition, we also focus on the STING inhibitors, representative structures, biological activity, and mechanisms of action.

Brain-related disorders are one of the world's most important and complex health problems today. These brain-related disorders are responsible for a massive number of morbidities and death all around the world. However, researchers have devoted a large amount of time to investigating these diseases and found positive results; nevertheless, there are currently quite a few medications available to treat them. Emodin (EM), a polyphenol compound, has many health benefits. It is a biologically active monomer derived from rhubarb root that exhibits anti-inflammation, anti-oxidation, anticancer, and neuroprotective properties. A series of preclinical trials have shown EM to have protective benefits against many brain-related diseases. This review has evaluated the potential of EM as a pharmacological agent for the treatment and management of various brain-related disorders based on the findings of multiple pre-clinical studies and taking into account the compound's therapeutic properties.

BACKGROUND: Cancer is a life-threatening disease worldwide, but proper treatment has not yet been developed. Many therapies are available to treat cancer disorders, like chemotherapy, surgery, hormone therapy, and immunotherapy. Chemotherapy often relies on a combination of harmful, highly toxic platinum-based compounds. Also, there are chances of poor distribution of chemotherapeutic agents and cytotoxic to most cells which leads to damage to other healthy cells, also, there are chances of resistance. OBJECTIVE: The main objective of this study is the development of mesoporous silica nanoparticles. Mesoporous silica nanoparticles are recognized as carriers with high drug loading capacity and significant functionalized surface area for targeted drug delivery. Mesoporous silica nanoparticles have shape, particle size, pore volume, higher surface area, and the possibility of surface modification. Hence results in thermally and chemically stable nanomaterials. For targeted drug delivery, MSN is conjugated with a variety of ligands, including monoclonal antibodies, hyaluronic acid, transferrin, folic acid, etc., that have a particular affinity for the receptors that are overexpressed on the surface of malignant cells, so using this nanocarrier reducing the dose related toxicity of normal cell. METHODS: This review focuses on different methods for synthesizing mesoporous silica nanoparticles. Sol-gel method and modified stobber method were used for the synthesis of this nanoparticle. RESULTS: Successfully synthesized mesoporous silica nanoparticle with particle size around 50-200 nm and drug loading efficiency was found to be around 71 %. CONCLUSION: Mesoporous silica nanoparticles are great carriers for intracellular and targeted drug delivery systems.

INTRODUCTION: Glioblastoma multiforme (GBM) has a poor prognosis, with current treatments providing no advantage in terms of survival. Certain new immunotherapy methods, such as peptide vaccines, have been used in clinical trials. In this meta-analysis, the effectiveness of peptide vaccinations on the survival rate of GBM patients was studied. METHOD: A comprehensive search was carried out using three electronic databases: PubMed, Scopus, and ISI. The purpose of this research was to assess overall survival (OS). The pooled overall one-year and two-year survival rates in GBM with peptide vaccination were calculated using the general inverse variance technique as random effects hazard ratios (HRs). In the study, subgroups of countries were compared with each other. Japan had the highest one-year survival rate, and the US had the highest two-year survival rate. RESULT: With 95% confidence intervals (CIs), the one-year OS rate in GBM patients treated with peptide vaccination increased significantly, but the two-year survival rate did not increase. As a result, while additional research is needed, it cannot be concluded that it is an effective therapy for GBM. CONCLUSION: Our study found that while peptide vaccination treatment did not increase second-year survival, it improved first-year survival. More research needs to be done to find effective vaccine-based treatments for GBM that can help patients survive longer.
