HTB maintains a collection of about 140 000 small molecule compounds including known drugs, bioactives, and diversified sets of chemicals. Standardization by Chemical Assay of Organic Drugs and Galenicals By standardization of a drug or medicinal preparation we mean bringing it to a definite strength as regards its medicinal activity. In addition, drug development must establish the physicochemical properties of the NCE: its chemical makeup, stability, and solubility. Human tumor clonogenic assays (HTCA) are being used to evaluate the chemosensitivity of human cancers to both standard and experimental anticancer drugs as well as to predict clinical tumor response and resistance to these agents. Lecture Outline • Quantification principles (1-8) –Analytical PK lab tasks • Chromatography (10-11) • Detection - spectroscopies –Optical (12-14) –Mass (15-27) Chemical assays • A chemical assay refers to the analysis of a sample material, called analyte, using a set of chemical procedures • Qualitative- extraction, distillation, precipitation and other methods that determine physicochemical properties • Quantitative- volume or weight of the substance Thus, an assay may be done for example to determine the level of thyroid hormones in the blood of a person suspected of being hypothyroid (or hyperthyroid).
