Lung cancer is one of the malignant tumors with fast-growing morbidity and mortality and the worst prognosis. The development of molecular biology and cell biology provides targets for the prevention and treatment of lung cancer and opens up new areas for the development of drugs and methods to treat lung cancer. Metastasis is the spread of cancer cells from the primary tumor to other parts of the body. It is a significant challenge in the treatment of cancer, as it often leads to poor patient outcomes. Therefore, identifying targets that can effectively inhibit or disrupt the metastatic process is crucial for developing new therapeutic strategies. Lung cancer, like other solid tumors, is more prone to early invasion and metastasis. Uridine diphosphate glucose (UDP-Glc) is an important intermediate in glycogen synthesis and is involved in many biological processes, Preclinical studies have found that in vivo application of UDPG in rats promotes intrinsic repair potential to immat

In toxicology studies, there are two main types of tests used to assess the safety and potential toxic effects of drugs: in vivo tests and in vitro tests. We know that the traditional method of drug toxicology research is to use animal models for in vivo drug testing. Although this method can fully reflect the various toxic effects of drugs and allow long-term observation of chronic toxic effects, there are many interfering factors and it is difficult to conduct metabolic and mechanistic studies. With the development of science and technology, the use of free organs, cultured cells, or organelles for toxicological in vitro testing has slowly emerged. Toxicology is the science of studying the harmful effects of chemical, physical, biological, and other exogenous factors on biological systems. It can study the toxic reactions of chemical substances on living organisms, their severity, frequency of occurrence, and mechanisms of toxic effects, as well as qualitative and quantitative ev

 Systemic lupus erythematosus (SLE) is an autoimmune disease that produces large amounts of immune complexes and autoantibodies and causes damage to the kidneys, skin, joints, and central nervous system. Current SLE treatment is mostly glucocorticoid-led drug therapy, which has more toxic side effects. With the understanding of the pathogenesis of SLE, some targets for the treatment of SLE have emerged, and drugs developed with these targets have achieved some results in preclinical studies and clinical studies. In the future, the development of some biologically targeted therapeutic agents will have an important role in the treatment of SLE. 1. What is Systemic Lupus Erythematosus? SLE is a complex autoimmune disease that can affect multiple organs, including the skin, joints, heart, kidneys, and brain. Symptoms can vary widely and may include fatigue, joint pain, skin rashes, and fever. The course of the disease is unpredictable, with periods of remission and flares. 2. What Causes S

The size of the particles is called particle size. The particle size of the API is closely related to the homogeneity of the preparation process in terms of mixing, the accuracy of dosage, and compressibility, and it has an impact on the solubility, duration of action, site of action, stability, and safety of the drug formulation. And the particle size control of drugs has an important influence on drug effectiveness, strength, and security. Therefore, particle size is an essential object of study in preformulation studies for innovative medicines. Preformulation research is a vital link in drug development, directly affecting the subsequent development process and final application of drugs. Preformulation research aims to determine the pros and cons of potential drug molecules at the initial research stage and to screen candidates for drug molecules, involving the synthesis of new drug molecules, biological activity screening, pharmacokinetics, toxicology, safety evaluation, etc

  The vaccine is a generic term for various biological products containing antigenic substances that induce specific active immunity in humans. In preclinical studies of vaccine, it is crucial to examine the safety of vaccines by performing preclinical safety evaluations with relevant animals. Drug safety evaluation in preclinical studies of new medicines refers to the use of greater than clinical doses or more prolonged than clinical dosing times to administer drugs to animals to discover and evaluate the potential toxic effects on the animal organism, the manifestations of toxicity, and the reversibility of target organ damage. This study helps to find toxic doses, detect harmful effects, determine safe dose ranges, search for unhealthy target organs, and assess the reversibility of toxicity. The difficulty of drug safety evaluation in vaccines is that the vaccine does not directly exert preventive or therapeutic effects but acts by inducing the immune system to produce antibodies

  Toxicokinetics is an essential element of preclinical studies of drugs. As an interdisciplinary discipline between pharmacokinetics and toxicology, toxicokinetics is a bridge and tool for advancing preclinical studies to clinical studies. The primary goal of toxicokinetic studies is to demonstrate the systematic exposure levels of new drugs in test animals during safety evaluation and their correlation with the administered dose and the course over time. Their studies generally include single-dose studies in toxicity studies, multiple-dose studies, tissue distribution studies, genotoxicity studies, carcinogenicity tests, reproductive toxicity studies, and toxicokinetic studies for specific drugs such as biotechnology. Toxicokinetics is based on pharmacokinetic studies, with the help of its methods and tools, to help evaluate drug safety and regulate research behavior according to GLP. As new drug research progresses, some compounds to be selected (both small and large molecules) are

  According to the drug development process, new drug development can be divided into preclinical and clinical studies of new drugs. The former is the sum of all the research work done on a drug before it enters clinical trials, and the latter is the research work done on a drug in clinical trials. From the discovery of a drug's effectiveness in animals to its testing in human clinical trials, researchers do a great deal of work to ensure that the potential for a cure to be effective is maximized while minimizing the potential for harm. Medicilon is a preclinical research outsourcing (CRO) company that can provide customized preclinical trial service solutions to clients with years of experience in R&D technology and expertise in drug metabolism, Pharmacokinetics, pharmacodynamic studies, and toxicology.
