.. class:: infomark

**What this tool does**

Filters a library of compounds based on user-defined physico-chemical parameters or predefined options (e.g. Ro5, lead-like properties, etc.). Multiple parameters can be selected for more specific queries.

-----

.. class:: warningmark

**Hint**

| If your input file is in SDF format you can use the *Compute physico-chemical properties* tool to precalulate the properties and use the filter on that precomputed dataset. It should be faster and can be reused but it's bigger than a SMILES file.
|
| For exact matches please use the target value for both minimum and maximum parameters (e.g. a selection of exactly 4 rotatable bonds can be performed by selecting 4 as minimum and maximum value).
|
| Selecting the same property multiple times with different parameters will result in querying the largest overlapping subset of values for the parameter (e.g. a selection of between 0 and 3 rotatable bonds plus a selection between 2 and 4 will result in a query for compounds between 2 and 3 rotatable bonds).

**Definition of the pre-defined filtering rules**

  **# Lipinski's Rule of Five:**
    =< 5 Hydrogen-bond donor groups

    =< 10 Hydrogen-bond acceptor groups

    =< 500 Molecular weight

    =< 5 octanol/water partition coefficient (log P)

  **# Lead Like properties** (Teague, Davis, Leeson, Oprea, Angew Chem Int Ed Engl. 1999 Dec 16;38(24):3743-3748):
    =< 7 rotatable bonds

    =< 350 Molecular weight

    =< 3.5 octanol/water partition coefficient (log P)

  **# Drug Like properties** (Lipinski, J Pharmacol Toxicol Methods. 2000 Jul-Aug;44(1):235-49):
    =< 10 Hydrogen-bond acceptor groups

    =< 8 rotatable bonds

    150 =< Molecular weight =< 500

    =< 150 Polar Surface Area

    =< 5 octanol/water partition coefficient (log P)

  **# Fragment Like properties** (Carr RA, Congreve M, Murray CW, Rees DC, Drug Discov Today. 2005 Jul 15;10(14):987):
    =< 5 rotatable bonds

    =< 250 Molecular weight

    =< 2.5 octanol/water partition coefficient (log P)
