In Vitro ADME Services
In the early stages of drug discovery, in vitro ADME studies (absorption, distribution, metabolism, and excretion) are critical in understanding candidate compounds' efficacy and safety. Our company has highly experienced and matured scientists capable of undertaking the entire set of services from drug discovery to pre-clinical studies to accelerate your ADME studies on the treatment of rare diseases.
Introduction to ADME
In vitro ADME studies are used to evaluate the absorption, distribution, metabolism, and elimination of drugs. In the early stages of drug discovery, in vitro ADME studies are used to identify chemotypes and lead compounds with favorable pharmacokinetic and toxicological profiles.
During the lead optimization and preclinical candidate stages, comprehensive in vitro ADME studies including protein binding, metabolic stability, drug interaction-related transporters, and CYP inhibition are often required to predict human pharmacokinetic properties. Optimizing the properties of ADME in drug design and screening can significantly reduce the failure rate of drug discovery. With the realization of new technologies and the improvement of existing technologies, high-throughput screening technology is widely used in ADME studies.

ADME studies can enable scientists to obtain more candidate molecule information in the drug discovery of rare diseases. In vitro ADME studies improve the efficiency of the development of drugs for rare diseases.
What Services Can We Provide?

Our company have the capabilities to provide professional communication and problem-solving support to carry out entire physiochemical studies. The physiochemical studies services we can provide include but are not limited to: blood partitioning, chemical stability, Kinetic / thermodynamic solubility, lipophilicity (LogD & LogP), pKa, and buffer stability.

The study of in vitro metabolism can help guide the synthesis optimization of lead compounds or drug candidates. Our company has extensive expertise in pharmacokinetics, particularly in vitro metabolism, our professional team can provide comprehensive services including cytochrome P450 studies, stability studies, protein binding studies, and metabolite ID/profiling.

In Vitro Permeability and Transporter Studies
In vitro permeability and transporter studies can influence pharmacokinetic, pharmacodynamic and toxicological properties. Protheagen has established a complete in vitro permeability and transporter studies system, which has been widely used in the selection of candidate compounds during the development process of rare disease new drug projects.
