Such a compound known as Drug It involves : Synthesis Structure activity relationship (SAR) Receptor interactions- Absorption          Distribution          Metabolism         Excretion  According to IUPAC: Medicinal chemistry it concern  discovery, development, Identification , Interpretation Of mode of action of biological active compounds at the molecular level Medicinal chemistry covers three stages Discovery step-   Involving choice of therapeutic Target (receptor, enzyme and target group, cellular invivo model).Identification or discovery. Production of new active substances interacting with selected target. Such compounds called Lead compound     2. An optimization step - Which deals with improvement of lead compound.The optimization process takes primarily into
