A biologic agentâs activity may be affected by the cell system in which it is produced, the fermentation media, or operating conditions. The use of living organisms to produce therapeutic extracts is not new.
where L =ligand (drug), R =receptor (attachment site), reaction dynamics that can be studied mathematically through tools such as free energy maps. Pharmacodynamics is often summarized as the study of what a drug does to the body, whereas pharmacokinetics is the study of what the body does to a drug.he desired activity of a drug is mainly due to successful targeting of one of the following: 1  Cellular membrane disruption. 2  Chemical reaction with downstream effects. 3  Interaction with enzyme proteins. 4  Interaction with structural proteins. 5  Interaction with carrier proteins. 6  Interaction with ion channels.
