Quantitative Structure–Activity Relationship (QSAR) is a scientific method used to relate the chemical structure of a molecule to its biological activity using mathematics and statistics. In simple terms, QSAR helps…
A prodrug is a medication that is inactive or only weakly active when taken, but becomes active after it is converted inside the body. The idea behind a prodrug is…
Combinatorial chemistry is a technique used to create large numbers of chemical compounds in a short period of time. It helps medicinal chemists design and test thousands of molecules rapidly…
Computer Aided Drug Design (CADD) refers to the use of computational tools to discover, design, and optimize new drug molecules. Instead of depending only on trial-and-error laboratory experiments, CADD helps…
Concept of Antisense Molecules Antisense technology is a modern approach used to block the production of specific proteins by interfering with the natural process of gene expression. It works by…
Local anti-infective agents are substances used on the skin, mucous membranes, or surfaces to destroy or inhibit harmful microorganisms. They include antiseptics, disinfectants, and other chemicals used to reduce infection…
Preservatives are chemical agents added to pharmaceutical formulations to prevent microbial contamination and increase the shelf-life of the product. They protect medicines from bacteria, fungi, and other microorganisms that may…
