Targeting Orexin Receptors (OX-1 and OX-2) for Developing Anti-Obesity Therapeutics

Inquiry

Overview

Intensive research on the pathogenesis of obesity has made anti-obesity therapies targeting specific receptors (Melanocortin 4 Receptor, Serotonin Receptor, OX receptor, etc.) a hot topic of research and new hope for a therapeutic modality. OX is a peptide neurotransmitter that is expressed predominantly by neurons in the lateral hypothalamic area. It stimulates appetite and plays a role in the regulation of sleep and wakefulness. The two receptors for OX, OX-1, and OX-2, show different affinities for different OX and exhibit different roles in metabolism and other behaviors. OX receptor modulators have been found to have potential as anti-obesity and anti-diabetic agents. Protheragen adheres to a client-first philosophy and offers a competitive anti-obesity therapy development service targeting the OX receptor.

Your Best Partner for Research on OX Receptor-Targeting Anti-Obesity Therapies

Our one-stop service for the development of anti-obesity therapies targeting the OX receptor includes everything from computer-aided drug design, compound synthesis, and preclinical studies to data analysis. As the ideal partner for anti-obesity therapeutics research, we are committed to creating customized solutions that exceed expectations and provide support at all stages of research. Specific services are listed below:

Anti-Obesity Drug Development

Computer-aided drug design: Our team includes researchers with deep scientific literacy and extensive experience working in computational chemistry. Based on advanced cheminformatics and modeling software, we rationally design anti-obesity drugs targeting OX receptors through molecular dynamics simulation and molecular docking based on theoretical computational methods of molecular structure. By analyzing and predicting the interactions between compounds and OX receptors, we design and optimize lead compounds, which greatly improves the level, speed, and success rate of drug design. We also perform drug-like properties assessment of potential anti-obesity drugs, including their absorption, distribution, metabolism, excretion, toxicity, etc., to filter out unsuitable compounds and improve the efficiency of research and development.

OX-1 receptor antagonist development: OX-1 receptor antagonists have been shown to reduce food intake and ultimately improve obesity. We develop highly potent and selective OX-1 receptor antagonists and analyze their binding affinity to the receptor by computer simulation. They are subsequently evaluated for anorexia, thermogenesis, and anti-obesity activity in obese models using obesity models.

OX-2 receptor modulator development: Enhanced OX-2 receptor signaling renders mice resistant to diet-induced obesity. OX-2 receptor selective agonist administration has been shown to inhibit high-fat diet-induced weight gain in mice. With our expertise in drug synthesis, we efficiently synthesize various OX-2 receptor modulators based on the prediction results and evaluate their effects on food intake, body weight, and other aspects.

Preclinical Studies of Anti-Obesity Therapies

Our research team combines a variety of cutting-edge technologies and highly efficient assays to evaluate the efficacy and therapeutic potential of anti-obesity drugs targeting the OX receptor. The assays are comprehensive and include safety, pharmacokinetics, pharmacodynamics, and bioassays. We are highly attentive to our client's research needs and focus on adopting a flexible approach.

Obesity models: Based on well-established experimental facilities and specialized modeling techniques, we offer a wide range of obesity models to study obesity and treatments.

In vitro studies: We have several types of in vitro cellular models to study the therapeutic efficacy of anti-obesity therapies targeting the OX receptor. The efficacy and safety of this therapy is assessed by analyzing metabolism, energy balance, etc.

In vivo studies: We select the appropriate route of administration for single and multiple dosing according to the characteristics of the anti-obesity drug. After a period of administration, changes in food intake, body weight, fat mass, gene expression profiles, etc., are detected in the animal model. The potential and safety of OX receptor antagonists in the treatment of obesity are assessed by accurate interpretation of the data.

Results: In this study, OX, OX-1 receptor, and OX-2 receptor-deficient mice were metabolically characterized to analyze the different roles of the two receptors in glucose metabolism and energy metabolism. The analyses revealed that OX-1 receptor-deficient mice showed resistance to diet-induced obesity regardless of diet. OX-2 receptor-deficient mice exhibited lower energy expenditure than wild-type mice when fed a high-fat diet. Both receptor-deficient mice gained weight similarly to the OX-deficient mice. Ultimately, analysis of body weight, appetite, energy expenditure, and glucose metabolism revealed that both OX receptor signals had specific roles in energy metabolism. This study provides theoretical support for the development of anti-obesity therapies targeting OX receptors.
