Launch of New Enhanced Version of chemPK™ Workflow Solution
 for Predicting Human Pharmacokinetics Directly from Chemical Structure

Cyprotex PLC (AIM:CRX), a specialist Contract Research Organisation (CRO), announced today the launch of version 2 of its in silico modelling solution, chemPK™, which predicts human pharmacokinetics directly from chemical structure. Pharmacokinetics is defined as the study of the concentration of a drug or chemical in the body over time, and is related to its absorption, distribution, metabolism and excretion. Understanding the pharmacokinetics is important for understanding the efficacy (effectiveness) or potential toxicity of drugs or chemicals following their administration.

The original version of chemPK™ was able to predict human pharmacokinetics following administration of a single oral dose. Version 2 now has the ability to predict human pharmacokinetics following administration of both oral and intravenous dose. It is also able to simulate repeat-dose administration and so is more relevant to the typical dosing regimen within the clinic. Unlike most competing products, chemPK™ uses a PBPK (physiologically-based pharmacokinetic) modelling approach which is a more robust technique for this purpose. The software is easy to implement and use. It operates on the freely available KNIME Analytics Platform for workflow management which facilitates integration with a wide range of other cheminformatics, analytics and modelling tools.

Dr Anthony Baxter, Cyprotex’s Chief Executive Officer, comments: 'chemPK™ is a valuable virtual screening tool which can be used at an early stage prior to chemical synthesis of a molecule. The recently developed version 2 improves the relevance of chemPK™ to different dosing routes and regimens in the clinic. Cyprotex have built an impressive range of software products for predicting pharmacokinetic processes and toxicity which are now being utilised within the industry for directing chemistry and prioritising in vitro and in vivo screening.’
