Preclinical trials absorption

Preclinical trials stage II Pharmacokinetics (absorption, distribution, metabolism, and excretion), subchronic toxicity, teratogenicity, mutagenicity, scale-up of synthesis, development of final dosage form, and production of clinical samples [Chemistry, Manufacturing, and Control (CMC) section for FDA],... 

The absorption, distribution, metabolism, and excretion in the species used in the toxicology trials should be discussed. Quantitative or notable qualitative differences in ADME between the various animal species and humans should be discussed, as well as any references to observed species differences in toxicity and extrapolation of the findings to humans. The significance of these findings to the interpretation of the results of the carcinogenicity, bioassay, and other preclinical toxicity trials should be considered. 

A DNA vaccine candidate that has successfully passed all preclinical hurdles needs to be tested clinically by a three-phased scheme as outlined in Chapter 4. As defined by a European Council directive, a clinical trial means ... any investigation in human subjects intended to discover or verify the clinical, pharmacological and/or other pharmacodynamic effects of. .. investigational medicinal product(s), and/or to identify any adverse reactions. .. and/or to study absorption, distribution. 

Both the theoretical materials and the experimental data presented in this book dearly demonstrate the significant progress that has recently been made in the application of stilbenes in chemistry, photochemistry, photophysics, materials sdence, biochemistry, biomedicine, and clinical research. This progress resulted to a great extent from interdisciplinary cooperation. Advances in synthetic chemistry that provided researchers in these areas with a wide assortment of stilbenes paved the way for their multiple applications in basic and applied research. Modifications of traditional physical techniques and advanced methods such as nano-, pico-, femtosecond absorption, fluorescence and vibrational time-resolved spectroscopy, and theoretical approaches to the analysis of experimental data ensure profound photophysical and photochemical investigations in the area. Experts in biochemistry, biomedicine, and medicine effectively used natural and synthetic stilbenes in biochemical and preclinical studies and recenfly in clinical trials.
