Pooled Human Cryopreserved Hepatocytes
Hepatocytes are the chief functional cells of the liver, responsible for the selective uptake, metabolism and excretion of most drugs. Cells for use in plate cultures or suspension assays represent a key tool for predicting properties such as hepatotoxicity, metabolism, and potential drug-drug interactions. Since these cells mimic the properties of the liver, researchers can evaluate the ...

Applications of nanotechnology in drug delivery systems for the treatment of cancer and diabetes
This paper discusses potential applications of nanotechnology in drug delivery systems and pharmacotherapeutics. There are a few limitations in the use of conventionally available drug delivery systems as pharmacological agents in disease treatment. Lack of target specificity, altered effects and diminished potency due to drug metabolism in the body, cytotoxicity of certain anti-carcinogenic ...

Cytochrome P450: A Vital Biosynthetic Enzymes for Drug Metabolism
Overview of Cytochrome P450 Cytochrome P450 (CYP450), is a family of hemoglobin-coupled monooxygenases. In mammals, CYP450 oxidizes steroids, fatty acids, and xenobiotics, playing an important role in the metabolism of various compounds as well as in the synthesis and breakdown of hormones. In plants, they regulate the synthesis of defense compounds, fatty acids, and hormones. With the progress ...

Lethal and sublethal effects of phthalate diesters in Silurana tropicalis larvae
Phthalates are compounds used in polymers to increase their flexibility and are now ubiquitous in the environment due to widespread use. As few studies have focused on the adverse effects of these chemicals in aquatic species, this study aimed to determine the effects of phthalate diesters in amphibians. Western clawed frog (Silurana tropicalis) tadpoles were acutely exposed to water spiked ...

TBECH‐mediated steroid hormone receptor activation and gene regulation in chicken LMH cells
The incorporation of brominated flame retardants into industrial and household appliances has increased their occurrence in the environment resulting in deleterious effects on wildlife. With the increasing restraints on available compounds there has been a shift to using BFRs that has seen the production of alternative BFRs such as 1,2‐dibromo‐4‐(1,2 dibromoethyl) cyclohexane (TBECH). TBECH ...

Understanding the Importance of Preclinical Animal Models in Drug Development
In the world of pharmaceuticals, developing safe and effective drugs is a complex and time-consuming process. Before a new drug candidate can progress to clinical trials and ultimately reach the market, it needs to undergo rigorous testing in various model systems to assess its efficacy and safety. One critical component of this evaluation is the use of preclinical animal models. Preclinical ...

How to Apply In Vitro DMPK Services to Support Drug Development and ADMET Study
Drug development is a complex and multifaceted process that involves extensive research and testing to ensure safety, efficacy and quality for human use. One critical element in the drug development process is drug metabolism and pharmacokinetics (DMPK), which refers to how a drug is absorbed, distributed, metabolized, and excreted (ADME) from the body. In vitro DMPK services, along with ...

An Overview of Isotopes
What are Isotopes? Isotopes are different atoms of the same element with the same number of protons and different numbers of neutrons called isotopes of each other, which can also be interpreted as different nuclides of the same element called isotopes of each other. An isotope is one of two or more atoms of the same chemical element with the same atomic number, occupying the same position on the ...

The Relationship Between the Gut Microbiome and Drugs Is Greater Than We Thought
Gut microbes are considered "virtual organs" that influence host health and are involved in disease research. The human gut microbiota has a large gene pool, encoding approximately 100-150 times more genes than the human genome, and contains a rich resource of enzymes with the ability to metabolize drugs. The diversity of gut bacteria also affects the mental health of the host. Microbiomes from ...

J.Med.Chem publish; Predicting Regioselectivity of AO, CYP, FMO and UGT Metabolism Using Quantum Mechanical Simulations and Machine Learning
Abstract – Unexpected metabolism in modification and conjugation phases can lead to the failure of many late-stage drug candidates or even withdrawals of approved drugs. Thus, it is critical to predict the sites of metabolism (SoM) for enzymes, which are known to interact with drug-like molecules, in the early stages of the research. The study presents methods for predicting the ...

Metabolomics in Gut Microbiota Research
With rapid development in sequencing technology, researchers can better assess the effect of the gut microbiome on human health. Human beings have a symbiotic relationship with the microbiota since birth. The environment, proximity to other humans and animals, diet, genetics, and time changes can all affect the microbial composition of our skin, mouth, and intestines. Compared with other ...

Brief Introduction of ADC Drug Production Technology
Drug-to-antibody ratio (DAR, drug-to-antibody ratio) The number of cytotoxic drugs connected to each antibody is the drug-to-antibody ratio (DAR). When the DAR increases, the drug metabolism rate of ADC drugs increases, the half-life decreases, and the systemic toxicity increases. Ideally, when the DAR is 4, the drug has the highest efficacy. Therefore, in actual production, the drugs with DAR ...

Tobacco smoke-dependent changes in cytochrome P450 1A1, 1A2, and 2E1 protein expressions in fetuses, newborns, pregnant rats, and human placenta
Tobacco smoke (TS) was described as a mixture of numerous cytochrome P450 (P450) substrates, inducers, and inhibitors. These inducers and inhibitors may modify drug clearance and xenobiotic or endogenous metabolism affecting P450s expression. In the present study, the effect of gestation and TS on: (1) cytochrome P450 CYP1A1, CYP1A2, and CYP2E1 protein expressions, and (2) cytochrome P450-linked ...
