A structural analog, also known as a chemical analog or simply an analog, is a compound having a structure similar to that of another compound, but differing from it in respect to a certain component. [1] [2] [3] It can differ in one or more atoms, functional groups, or substructures, which are replaced with other atoms, groups, or ...
The probe is typically an analog of the drug whose mechanism is being studied, so covalent labeling of an enzyme is indicative of drug binding. ABPP probes are designed with three key functional units: (1) a site-directed covalent warhead (reactive group); (2) a reporter tag, such as biotin or rhodamine; and (3) a linker group. [8]
5-Ethynyl-2′-deoxyuridine (EdU) is a thymidine analogue which is incorporated into the DNA of dividing cells. EdU is used to assay DNA synthesis in cell culture and detect cells in embryonic, neonatal and adult animals which have undergone DNA synthesis. [ 1 ]
In chemistry, a derivative is a compound that is derived from a similar compound by a chemical reaction.. In the past, derivative also meant a compound that can be imagined to arise from another compound, if one atom or group of atoms is replaced with another atom or group of atoms, [1] but modern chemical language now uses the term structural analog for this meaning, thus eliminating ambiguity.
In analytical chemistry, sample preparation (working-up) refers to the ways in which a sample is treated prior to its analyses. Preparation is a very important step in most analytical techniques, because the techniques are often not responsive to the analyte in its in-situ form, or the results are distorted by interfering species.
chemical stability; synthetic tractability; patentability; The project team will usually select between three and six compound series to be further explored. The next step will allow the testing of analogous compounds to determine a quantitative structure-activity relationship (QSAR). Analogs can be quickly selected from an internal library or ...
Studies shown that a boronic acid moiety adopts a tetrahedral configuration and serves as an inhibitor. In addition, the sulfonamide functional group can also mimic the transition state structure. [12] Evidence of boronic acid mimics as transition state analogue inhibitors of human arginase I was elucidated by x-ray crystal structures. [13]
Analog observation is, in contrast to naturalistic observation, a research tool by which a subject is observed in an artificial setting. [1] Typically, types of settings in which analog observation is utilized include clinical offices or research laboratories, but, by definition, analog observations can be made in any artificial environment, even if the environment is one which the subject is ...
