Summary
A new nomenclature system proposes prefixes to nonproprietary drug names, indicating stereochemical information. This system aims to improve drug identification and understanding of stereoisomerism in drug action and research.
Area of Science:
- Pharmaceutical Chemistry
- Medicinal Chemistry
- Drug Nomenclature
Background:
- Stereochemistry significantly impacts drug action and disposition.
- Current nonproprietary drug names often lack stereochemical details.
- Existing drug dictionaries (e.g., USP Dictionary of USAN) do not convey stereochemical information.
Purpose of the Study:
- To develop a nonproprietary drug nomenclature system that includes stereochemical information.
- To enhance drug identification and therapeutic understanding through nomenclature.
Main Methods:
- Analysis of stereochemical data in drug dictionaries and chemical literature.
- Design of a novel nomenclature system with stereochemical prefixes.
Main Results:
- A new system was designed with five prefixes: [dex]-, [lev]-, [rac]-, [uni]-, and [mix]-.
- These prefixes denote specific stereoisomeric forms (single enantiomers, racemic mixtures, etc.).
- The system provides a "flag" for stereochemical elements in drug structures.
Conclusions:
- The proposed nomenclature system offers valuable stereochemical insights.
- It is expected to benefit drug information, therapy, and research domains.
- Improved drug nomenclature can lead to safer and more effective drug utilization.

01:17Drug Nomenclature
2.8K
During the development of a new pharmaceutical, the manufacturer initially assigns a code name to the drug. Once approved, the drug receives a United States Adopted Name (USAN)—a generic, nonproprietary designation. Upon being listed in the United States Pharmacopeia, this nonproprietary name becomes the drug's official name. Additionally, the manufacturer assigns a proprietary name or trademark, which serves as the brand name under which the drug is marketed. It is worth noting that...

02:21Naming Enantiomers
25.1K
The naming of enantiomers employs the Cahn–Ingold–Prelog rules that involve assigning priorities to different substituent groups at a chiral center. Each enantiomer, being a distinct molecule, is assigned a unique name by the Cahn–Ingold–Prelog (CIP) rules, also called the R–S system. The prefix R- or S- attached to the chiral centers in an enantiomer is dependent on the spatial arrangement of the four substituents on the chiral center. The R–S system essentially comprises three...

01:12Nomenclature of Secondary and Tertiary Amines
5.0K
The secondary and tertiary amines are derivatives of ammonia, where two and three of its hydrogens are replaced by alkyl groups, respectively. Secondary and tertiary amines can be symmetrical with identical alkyl groups attached to the nitrogen atom or unsymmetrical when more than one type of alkyl group is present. The standard nomenclature of secondary and tertiary amines is similar to the names given to the primary amines. They are generally named alkylamines. As depicted in Figure 1, for...

01:09¹H NMR: Pople Notation
2.4K
The Pople nomenclature system classifies spin systems based on the difference between their chemical shifts. Coupled spins are denoted by capital letters with subscripts indicating the number of equivalent nuclei. When the coupled nuclei have well-separated chemical shifts, they are assigned letters that are far apart in the alphabet, such as A and X. When the difference in chemical shifts is small, coupled nuclei are named using adjacent letters of the alphabet (AB, MN, or XY).

01:10Nomenclature of Aryl and Heterocyclic Amines
3.0K
The simplest aromatic amine is phenylamine, which contains an –NH2 functionality directly attached to an aromatic ring. The name aniline is designated for this skeleton. As shown in Figure 1, the common names of the functionalized anilines involve prefixes ortho-, meta-, and para- to indicate the substitution position. Different functionalized aniline derivatives also have notable trivial names.

02:39Nomenclature of Alkynes
20.7K
Alkynes are unsaturated hydrocarbons characterized by the presence of carbon-carbon triple bonds and have a general formula CnH2n-2. The nomenclature of alkynes follows a set of rules similar to alkanes and alkenes; however, alkynes bear the suffix "-yne" instead of "-ane" or "-ene." There are two approaches to naming alkynes:
