Medicinal or pharmaceutical chemistry is a scientific discipline at the intersection of chemistry and pharmacy involved with designing and developing pharmaceutical drugs. Medicinal chemistry involves the identification, synthesis and development of new chemical entities suitable for therapeutic use. It also includes the study of existing drugs ...
D010600. Pharmacology is the science of drugs and medications, [ 1] including a substance's origin, composition, pharmacokinetics, pharmacodynamics, therapeutic use, and toxicology. More specifically, it is the study of the interactions that occur between a living organism and chemicals that affect normal or abnormal biochemical function. [ 2]
Lipinski's rule of five, also known as Pfizer's rule of five or simply the rule of five ( RO5 ), is a rule of thumb to evaluate druglikeness or determine if a chemical compound with a certain pharmacological or biological activity has chemical properties and physical properties that would likely make it an orally active drug in humans.
Definition. Phytochemicals are chemicals of plant origin. [ 1] Phytochemicals (from Greek phyto, meaning "plant") are chemicals produced by plants through primary or secondary metabolism. [ 2][ 3] They generally have biological activity in the plant host and play a role in plant growth or defense against competitors, pathogens, or predators.
Pharmacognosy is the study of crude drugs obtained from medicinal plants, animals, fungi, and other natural sources. [ 1] The American Society of Pharmacognosy defines pharmacognosy as "the study of the physical, chemical, biochemical, and biological properties of drugs, drug substances, or potential drugs or drug substances of natural origin ...
t. e. Physical chemistry is the study of macroscopic and microscopic phenomena in chemical systems in terms of the principles, practices, and concepts of physics such as motion, energy, force, time, thermodynamics, quantum chemistry, statistical mechanics, analytical dynamics and chemical equilibria . Physical chemistry, in contrast to chemical ...
Biophysical chemistry is a physical science that uses the concepts of physics and physical chemistry for the study of biological systems. [1] The most common feature of the research in this subject is to seek an explanation of the various phenomena in biological systems in terms of either the molecules that make up the system or the supra-molecular structure of these systems. [2]
Physical biochemistry is a branch of biochemistry that deals with the theory, techniques, and methodology used to study the physical chemistry of biomolecules. It also deals with the mathematical approaches for the analysis of biochemical reaction and the modelling of biological systems. It provides insight into the structure of macromolecules ...
