Study of general toxicity

• Acute toxicity
• Sub-acute toxicity
• Chronic toxicity

Study of specific toxicity

• Reproductive toxicity
  • Study of the embryotropic action of chemical compounds, including drugs, on experimental animals (reproductive toxicity and genotoxicity).
  • Assessment of the female and male generative functions by integral and specific indicators in the experiment.
• Immunotoxicity at single and course administration of test chemicals
• Allergenicity
• Mutagenicity

Toxicity assessment is carried out in accordance with the OECD protocols for the testing of chemicals, GOST standards, The guidelines for preclinical and clinical studies of drugs (A.N. Mironov, N.D. Bunatyan and others — M.: Grif and K, 2012).

Discovery of new drugs by screening pharmacological activity

• by type of biological target (molecular, cellular, etc.)
• by type of screening panel: genetic, chemical
• by spectrum of the screening panel: non-directional, directional
• by purpose: search, optimization

• Development / adaptation of analytical methods for the dissolution test and in vitro study of active ingredients release
• Comparative dissolution kinetics test
• Validation of analytical methods
• Stability study of objects in conditions of natural storage and “accelerated” aging

Analytical Chemical researches are conducted in accordance with the principles of Good Laboratory Practice (GLP).

• Development and adoption of hygienic standards (safe reference levels of impact, maximum allowable concentration) of chemical and biological factors in the air of the working zone and atmospheric air of urban and rural settlements

Development and adoption of hygienic standards of chemical and biological factors is carried out in accordance with the Decree of the Chief Sanitary Inspector of the Russian Federation № 25 of February 13, 2018 and sanitary-epidemiological rules and regulations of the Russian Federation.
