**What does this tool do?**

This tool computes the Euclidean distance between the Spectrophores(TM) descriptors of the target to each molecule stored in the library.

|Spectrophores (TM)| search
		|Spectrophores (TM)| is a screening technology by Silicos_ which converts three-dimensional molecular property data into one-dimensional spectra. Typical characteristics that can be converted include electrostatic potentials, molecular shape, lipophilicity, hardness and softness potentials. The computation is independent of the position and orientation of a molecule and allows an easy comparison of |Spectrophores (TM)| of different molecules.

		Molecules with similar three-dimensional properties and shape, and therefore also similar biological activities, always have similar |Spectrophores (TM)|. As a result this technique is a very powerful tool to investigate the similarity of molecules and can be applied as a screening tool for molecular databases, virtual screening, and database characterisations.

*Advantages:*

- |Spectrophores (TM)| can realistically compute ligand-protein interactions based on aforementioned molecular descriptors
- |Spectrophores (TM)| can be applied in both a ligand- or target-based setting
- |Spectrophores (TM)| can distinguish, if needed, between the different enantiomers of stereo-selective compounds
- |Spectrophores (TM)| can be computed fast

.. |Spectrophores (TM)| unicode:: Spectrophores U+2122

**Hint** this tool is useful to select compounds with similar chemical features to a target, but accounting for the discovery of diverse scaffolds. This is in contrast to the results expected in a similarity search based on atom connectivity.

Silicos_ - |Spectrophores (TM)| is a registered tool implemented in the open-source OpenBabel.
