The term "me-too drug" or "follow-on drug" refers to a medication that is similar to a pre-existing drug, usually by making minor modifications to the prototype, reflected in slight changes in the profiles of side effects or activity, and used to treat conditions for which drugs already exist.
In organic chemistry, diazirines are a class of organic molecules consisting of a carbon bound to two nitrogen atoms, which are double-bonded to each other, forming a cyclopropene-like ring, 3H-diazirine (>CN 2). They are isomeric with diazocarbon groups (>C=N=N), and like them can serve as precursors for carbenes by loss of a molecule of ...
Chemistry portal; Medicine portal; MedChemComm (in full: Medicinal Chemistry Communications) is a peer-reviewed scientific journal publishing original (primary) research and review articles on all aspects of medicinal chemistry, including drug discovery, pharmacology and pharmaceutical chemistry.
Penams are the primary skeleton structures that define the penicillin subclass of the broader β-lactam family of antibiotics and related compounds. They are bicyclic ring systems containing a β-lactam moiety fused with a five-member thiazolidine ring.
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.
Forward (classical) and reverse pharmacology approaches in drug discovery. In the field of drug discovery, classical pharmacology, [1] also known as forward pharmacology, [2] [3] [4] or phenotypic drug discovery (PDD), [5] relies on phenotypic screening (screening in intact cells or whole organisms) of chemical libraries of synthetic small molecules, natural products or extracts to identify ...
Drug metabolism is the metabolic breakdown of drugs by living organisms, usually through specialized enzymatic systems. More generally, xenobiotic metabolism (from the Greek xenos "stranger" and biotic "related to living beings") is the set of metabolic pathways that modify the chemical structure of xenobiotics, which are compounds foreign to an organism's normal biochemistry, such as any drug ...
In organic chemistry, a cross-coupling reaction is a reaction where two different fragments are joined. Cross-couplings are a subset of the more general coupling reactions. Often cross-coupling reactions require metal catalysts. One important reaction type is this:
