What is chemistry of a drug?
Drugs are a way of modifying the chemistry of the body. They can be used to treat diseases and infections, correct imbalances in electrolytes and fluids, or alter mental status (such as inducing amnesia or stopping hallucinations).
What are natural products chemistry?
A natural product is a chemical compound or substance produced by a living organism—that is, found in nature. The term natural product has also been extended for commercial purposes to refer to cosmetics, dietary supplements, and foods produced from natural sources without added artificial ingredients.
What is natural product chemistry PDF?
Natural products are those chemical compounds or substances that are isolated from living organism. It can be in form of primary or secondary metabolites. These secondary metabolites are classified into three namely; Terpenes, Phenolic compounds and Nitrogen-containing compounds.
What are the types of medicinal chemistry?

What are the six types of drugs?
The 6 Classifications of Drugs. When considering only their chemical makeup, there are six main classifications of drugs: alcohol, opioids, benzodiazepines, cannabinoids, barbiturates, and hallucinogens.
What are the sources of natural drugs?
The most dominant natural medicine source is plants, due to their chemical and structural diversity and the biodiversity of their components. Examples of medicines that are derived from plants are aspirin (from willow tree bark) (2), digoxin (from the flower, Digitalis lanata) (3) and morphine (from opium) (4).
What are the uses of natural products?
Natural products are the active components of traditional and modern medicines. As the structural diversity of natural products helps in the chemical synthesis, and synthetic analogs can be prepared with improved potency and safety, these are often used as the starting points of drug discovery.
Why are natural products important?
Throughout our evolution, the importance of natural products for medicine and health has been enormous. Since our earliest ancestors chewed on certain herbs to relieve pain, or wrapped leaves around wounds to improve healing, natural products have often been the sole means to treat diseases and injuries.
What are the different classification of drugs?
DREs classify drugs in one of seven categories: central nervous system (CNS) depressants, CNS stimulants, hallucinogens, dissociative anesthetics, narcotic analgesics, inhalants, and cannabis.
What is the organic chemistry of drug synthesis?
The first volume of The Organic Chemistry of Drug Synthesis was orig- inally visualized as a single free-standing book that outlined the syntheses of most drugs that had been assigned non-proprietary names in 1975 at the timethebookwaswritten.Withinayearorsoofpublicationin1977,ithad become evident thata good many drugs had been overlooked.
What is medicinal chemistry?
INTRODUCTION Definition Medicinal chemistry, also called therapeutic chemistry, pharmaceutical chemistry, pharmacochemistry, and chemical pharmacy is that field of pharmaceutical sciences which applies the principles of chemistry and biology to the creation of knowledge leading to the introduction of new therapeutic agents.
How do medicinal chemists design better drugs?
In order to design better drug the medicinal chemist need to understand not only the mechanism by which a drug exerts its effect, but also the physicochemical properties of the lead molecule and the relative contributions that each functional group makes to the overall physicochemical properties of the molecule.
What are the basic principles of drug design?
Basically, it consists of taking a well-established chemical substance of known biological activity as a lead or prototype and then synthesizing and testing its structural congeners, homologes, or analogs. BASIC PRINCIPLES OF DRUG DESIGN
