+
+Search the ChEMBL database for compounds which resemble a SMILES string. Two 
+search options are possible: similarity (searches for compounds which are 
+similar to the input within a specified Tanimoto cutoff) and substructure 
+(searches for compounds which contain the input substructure).
+
+Results can be filtered for compounds which are 1) approved drugs 2) biotherapeutic
+3) natural products and 4) fulfil all of the Lipinski rule of five criteria.

+.. class:: infomark
+
+**Input**
+
+A single molecule in SMILES format. This can be submitted either as text or as a 
+file containing the SMILES string on the first line. Note that if the file contains 
+multiple lines, only the SMILES string on the first line will be used for the search.
+
+-----
+
+.. class:: infomark
+
+**Output**
+
+A SMILES file with search results, each on a new line.
