 In innovative drug development, conducting toxicology studies to determine the type, dose, and mechanism of toxic response to a drug is essential to deciding on a drug's safety and efficacy, developing safe drug use strategies, and avoiding unnecessary drug toxicities. Generally, drug toxicology research includes the following : (1) Toxicity testing : drug toxicity tests are conducted in experimental animals or cells to assess the harmful effects of drugs on organisms. (2) Mechanism of toxicity studies : To understand the causes of toxic reactions by studying the mechanism of action of drugs. (3) Toxicity assessment: To assess drug safety and potential risks and develop reasonable drug use strategies. (4) Toxicological monitoring : to monitor the population using the drug and understand the long-term toxicity and adverse effects. In the early stage of R&D, the early combination of toxicological screening and evaluation can help improve the success rate of innovat...

 In the process of new drug development, it is necessary to conduct pharmacokinetic studies to analyze the pharmacokinetic parameters of drugs in vivo and use them as their outstanding advantages and effects.  Generally speaking, drugs with exceptional benefits should have shallow toxic side effects, good pharmacodynamic and pharmacokinetic properties, high efficiency of utilization and absorption, high solubility, and low toxicity of metabolites in vivo, etc., which can be used to guide new drug development and clinical drug use. The drug’s utilization and absorption efficiency are relatively high, and it has relatively high solubility. Moreover, the toxicity of metabolites in the body is relatively low, which can be used to guide the development of new drugs and clinical medication. Pharmacokinetics is a discipline that adopts mathematical principles and methods to quantitatively analyze and describe the dynamic processes of drugs and their regularity in vivo, which can qu...

 Duhaldea cappa chrysanthemum belongs to traditional Chinese medicine in China. The study found that Duhaldea cappa chrysanthemum extract has an antibacterial effect on Staphylococcus aureus, a new antibacterial drug resource with potential for development.  The analysis of metabolites in the feces of rats after the administration of Duhaldea cappa extract is of great significance for the rational use of this herb and the development of new dosage forms. MetID plays a key role in drug discovery, preclinical development, and clinical development and is crucial for drug safety research and new drug development. Generally speaking, herbal medicines have antimicrobial activity due to various chemical components in the extracts. The analysis of metabolites of the active ingredients of herbal medications in animals and humans is essential for elucidating the effectiveness of herbal medicines, exploring the principles of action of the active ingredients, and explaining the rationali...

 Breast cancer is a common malignancy in women, and multidrug resistance is one of the main reasons affecting the efficacy of chemotherapy and patient survival in breast cancer. A tumor drug resistance-associated protein, BCRP, has been reported in breast cancer drug-resistant cell lines.  Also, BCRP is a transporter, mainly responsible for the excretion of endogenous and exogenous substances outside the cell, and has a vital role in drug metabolism research. The BCRP gene of human breast cancer resistance protein (BCRP) is located in the chromosome 4q22 region. It encodes 655 amino acids, which are present in several vital organs in the body, such as the small intestine, placenta, liver, and kidney. It is essential for drug absorption, distribution, metabolism, and excretion. Drug transport proteins play a vital role in drug metabolism kinetics. According to the drug transport mode, drug transport proteins can be divided into drug uptake proteins and drug efflux proteins....

 Natural products and their derivatives are essential for various drug lead compounds. Finding new drugs from active natural product skeletons and optimizing lead compounds is critical to drug development. Some chemical components of Chinese medicines are of great interest to pharmaceutical R&D workers because they may have multiple pharmacological activities .  Understanding the metabolism of natural products isolated from plants or synthesized using chemical methods in vivo can provide an individual material basis for pharmacodynamic and pharmacological studies of the drug. Rats or mice are usually used as animal models for the analysis of metabolites of compounds in vivo. Drug metabolism is one of the critical factors affecting the action of drugs. Studying the pathways and stability of drug metabolism, the enzymes and kinetic parameters involved in metabolism, and the drug interaction problems caused by metabolism are necessary to find efficient and less toxic drugs. T...

People may take medicine when they catch a cold daily; some take tablets, and some take capsules; these tablets and capsules are pharmaceutical preparations. Pre-prescription study of drug formulation is the understanding, analysis, utilization, or improvement of a series of fundamental physical, chemical, and formulation properties of a drug before designing a formulation prescription to make the drug stable, effective, and in line with the requirements of formulation prescription and formulation process in industrial production. Medicilon can provide professional pre-prescribing services and uncover valuable information to lead the compound into late-stage development for tiny quantities of active pharmaceutical ingredients or candidate compounds with drug-forming properties. The impact of physical properties of active pharmaceutical ingredients (APIs) on pre-prescription studies of injectables is one of the main points of pre-prescription studies of injectables, which are mainly re...
