Common Receptor-Complement Feature Among Some Antileukemic Compounds

A Comparison of Common Interatomic Distances in Serotonin and Some Hallucinogenic Drugs

“…Triangular patterns o f different distances, atoms, and shapes have previously been reported in explaining other receptors (2,3,5). The triangular pattern observed here may be useful in designing and explaining the activity o f these and other hallucinogenic agents.…”

Chemoinformatics Research at the University of Sheffield: A History and Citation Analysis

“…The resulting inter-atomic distance matrix could then be inspected for the presence of a query pharmacophore, or pharmacophoric pattern, i.e., the arrangement of structural features in 3D space necessary for a molecule to bind at an active site; an example of an anti-leukemic pharmacophore [12] is shown in Figure 2. Given that a 3D structure can be represented by a graph, the presence or absence of a pharmacophoric pattern can be confirmed by means of a subgraph isomorphism procedure in which the edges in a database structure and a query substructure are matched if they denote the same inter-atomic distance (to within any user-specified tolerance such as ±0.5Å).…”

Comparison of Antineoplastic Activity of Aminoethylaminoanthraquinones and Anthracycline Antibiotics

“…In 1970, the presence of a common N-0-0 triangular feature among a number of antileukemic compounds, including doxorubicin and daunorubicin, was postulated (7). Based on this report, Adamson (8) proposed replacing the amino sugar portion of these antibiotics, believed to cause their cardiotoxicity, with amino-containing functions having the nitrogen atom placed at a proper spatial distance from the oxygen atoms of the aglycone portion.…”
