Elucidating the mechanism of cellular
However, this method could also be used for finding new targets for existing or newly developed drugs.By identifying the pharmacophore of the drug molecule, the profiling method of pattern recognition can be carried out where a new target is identified.Rather, aspirin is the only NSAID that irreversibly inhibits COX-1. However, even though the mechanism of action of a certain drug is unknown, the drug still functions; it is just unknown or unclear how the drug interacts with receptors and produces its therapeutic effect.In some literature articles, the term mechanism of action and mode of action (Mo A) are used interchangeably; typically referring to the way in which the drug interacts and produces a medical effect.The data is consistent with NMR data and further supported with CD spectroscopy.Clark, Tiffany D., “Elucidating the Mechanism of Action of Unnatural Amino Acid Containing Antimicrobial Peptides in Membrane Environments” (Doctoral Dissertation., East Carolina University, January 2012).

Omics based methods use omics technologies, such as reverse genetics and genomics, transcriptomics, and proteomics, to identify the potential targets of the compound of interest.However, in actuality, a mode of action describes functional or anatomical changes, at the cellular level, resulting from the exposure of a living organism to a substance.This differs from a mechanism of action, as it is a more specific term that focuses on the interaction between the drug itself and an enzyme or receptor and its particular form of interaction, whether through inhibition, activation, agonism, or antagonism.Cancer cells, in contrast, develop mechanisms to suppress anoikis, allowing them to metastasize through the lymphovascular system to secondary organ sites.In this thesis, we utilized screening methodologies to identify novel signaling mechanisms of anoikis resistance in cancer cells.
