Structural Isomerism

Isomerism in Complexes
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can be...
Gene Families01:57

Gene Families

Gene families consist of groups of genes proposed to have originated from a common ancestor. Typically these arise through events in which a gene or genes are mistakenly duplicated during cell division. Unlike their parent genes (which are subject to selection pressure to maintain function), these gene copies do not need to preserve their sequences and may evolve at a relatively faster rate.
Occasionally these regions can be adapted to take on new roles within the organism, becoming novel genes...
Factors Affecting Dissolution: Polymorphism, Amorphism and Pseudopolymorphism01:21

Factors Affecting Dissolution: Polymorphism, Amorphism and Pseudopolymorphism

Polymorphism refers to the existence of a drug substance in multiple crystalline forms, known as polymorphs. Recently, this term has been expanded to include solvates (forms containing a solvent), amorphous forms (non-crystalline forms), and desolvated solvates (forms from which the solvent has been removed).
Some polymorphic crystals possess lower aqueous solubility than their amorphous counterparts, leading to incomplete absorption. For instance, the oral suspension of Chloramphenicol, which...

    Area of Science:

    • Crystallography
    • Medicinal Chemistry
    • Materials Science

    Background:

    • Diosgenone is investigated as a novel therapeutic agent for malaria treatment.
    • Previous crystallographic studies reported a polymorph of diosgenone with specific molecular arrangements.

    Purpose of the Study:

    • To report the crystallographic structure of a new diosgenone polymorph.
    • To compare the molecular arrangement of the new polymorph with previously reported structures.

    Main Methods:

    • Single-crystal X-ray diffraction analysis was employed.
    • The crystal structure was solved and refined.

    Main Results:

    • A new polymorph of diosgenone was identified in the space group P2(1).
    • The asymmetric unit contains two independent molecules with similar conformations.
    • The molecules in the new polymorph are arranged in a parallel orientation, contrasting with the anti-parallel arrangement in the previously reported structure.

    Conclusions:

    • The study reveals dimorphism in diosgenone crystal structures.
    • The altered molecular orientation in the new polymorph may influence its physical and therapeutic properties.
