Preclinical research services

We are proud to offer our best expertise and 1st-class preclinical services to your organization.

ChemRar provides a range of in vitro ADME/T assays to evaluate and improve metabolism, bioavailability, pharmacology, and toxicology characteristics of screening compounds during early stages of hit expansion and lead optimization.

For in vivo studies ChemRar offers:

  • Pharmacokinetics, tissue distribution, excretion
  • Routes of administration: PO, IM, IP, IV, SC, inhalation, topical
  • In vivo Efficacy Models (CNS, Oncology, Inflammation, etc)
  • Preliminary tox studies (dose-range finding, MTD)
  • Regulatory Toxicity Studies including formulation analysis and toxicokinetics
  • Animals: mice and rats (in-house), rabbits, dogs, monkeys (with partners)

ChemRar has developed a large number of animal models that are offered as a service to our clients. Areas of specialization include CNS (psychiatric and neurological diseases); metabolic and diabetes; oncology; infectious diseases and cardiovascular disorders. We are constantly adding to these model systems and our experienced pharmacologists will be pleased to discuss your needs. All model systems are fully validated and follow SOPs. Full compliance with the humane treatment of animals is respected for all studies and they are conducted in state-of-the-art facilities according to regulatory guidelines.

The following tests are run routinely and are fully validated.

Many additional models can be provided on request:
