Multiple Substructure Search

The Multiple Substructure Search enables one to search compounds by including or excluding FGROUP or SUBSTRUCTURE entries.

Step 1: Cookies have to be enabled.
Step 2: The Multiple Substructure Search page is seen by clicking "Multiple" in the menu (1). If no FGROUP or SUBSTRUCTURE entry has been looked up in your computer, the list of recently searched entry is empty as shown in the picture below.

Step 3: After FGROUP or SUBSTRUCTURE entries are searched (2,3), they are added to the list of recently searched entry (4).

Step 4: More FGROUP or SUBSTRUCTURE entries can be added to the list in the same ways (5-7). Data of recently searched items are stored in your computer as cookies, which will expire automatically in 7 days.

Step 5: Check Include or Exclude the recently searched items (8) and press Submit (9), then the Multiple Substructure Search will be performed. You do not necessarily check all items; the only items that are checked will take effect in the search. It may take several minutes, so please wait until the total result is shown.

Searching FGROUP

Each FGROUP entry has an ID number and one or more names, which can be searched using the Text-search option. Other search options are described below. To begin the search, click on the hyperlink describing the type of search you want to perform.

Method	Explanation	Detail
Text search	Looking up FGROUPs by name or ID	(Help)
Tree search	Hierarchical classification tree based on elements and topology
Structure search	based on elements, electrostatic and physicochemical properties	(Help)

Searching SUBSTRUCTURE

All SUBSTRUCTURE entries have ID numbers to be looked up by Text-search option. Some of them have links to FGROUP entries, by which SUBSTRUCTURE entries can be found. There is another option to look up SUBSTRUCTURE entries:

Method	Explanation	Detail
Text search	Looking up SUBSTRUCTUREs by ID	(Help)
