Subject:      New "Advanced" version of the ChemIDplus chemical search database
              available

The Division of Specialized Information Services (SIS) of the United States
National Library of Medicine (NLM) announces a new "Advanced" version of the
ChemIDplus chemical search database (
<http://chem.sis.nlm.nih.gov/chemidplus/chemidheavy.jsp>
http://chem.sis.nlm.nih.gov/chemidplus/chemidheavy.jsp). ChemIDplus Advanced
complements the recently released ChemIDplus Lite (
<http://chem2.sis.nlm.nih.gov/chemidplus/chemidlite.jsp>
http://chem2.sis.nlm.nih.gov/chemidplus/chemidlite.jsp), which does not
allow structure searching.

ChemIDplus Advanced replaces the previous structure search page. It provides
greater searching options, such as:

        **Chemical Structure searching using the newest MDL ISISDirect
software (by substructure, similarity, and individual structure)

        **Chemical Structure drawing input by the ChemAxon Marvin Java
applet, editor, as well as the MDL Chime and ISISDraw combination

        **Numeric searching by biological endpoints, including LD50 and LC50
(the user may specify Test, Species, Route, and Effect; both ranging and
exact match are available)

        **Numeric chemical property search and display on eight fields such
as Melting Point and Boiling Point, Water Solubility, LogP, and molecular
weight

        **Tracking of your query history, including display of structures
searched, and the capability to re-run or modify old searches during a
session.

        The Advanced and Lite interfaces run against the same ChemIDplus
database as previously, with the addition of new chemical and biological
data tables to give property searching capability.
