Integration of ACD/Labs Calculators and Symyx Draw Promotes

SANTA CLARA, Calif. & TORONTO–(BUSINESS WIRE)–Symyx Technologies, Inc. (Nasdaq:SMMX) and Advanced Chemistry Development (ACD/Labs) today announced the availability of no-charge add-ins to Symyx Draw (previously MDL Draw). The add-ins calculate physical properties, generate IUPAC nomenclature and predict NMR chemical shifts. Researchers can now increase the power and potential of this popular chemical drawing tool while generating and storing relevant data within the Symyx Isentris environment.

The Symyx Draw calculator add-ins enable researchers to calculate molecular properties such as pKa, logD, logP and solubility, generate IUPAC names and predict 13C NMR and 1H NMR chemical shifts and coupling constants, as well as 2D NMR spectra without leaving the Isentris environment, resulting in smoother workflows and increased productivity. Bioconcentration factor, adsorption coefficient and boiling point calculators round out the suite of available tools.

ACD/Labs Name, PhysChem and NMR predictors are recognized as industry-standard tools in the life sciences and chemicals industries. The outstanding accuracy of the prediction algorithms has been refined over more than 12 years of continuous development by ACD/Labs.

It has made a lot of sense to combine our strengths, said Val Kulkov, CEO of ACD/Labs. We are partnering with Symyx to provide integrated solutions that offer researchers chemical naming and spectral and physicochemical property predictions out-of-the-box with Isentris.

Symyxs partnership with ACD/Labs has resulted in a high-value win for our mutual customers, said Timothy Campbell, President of Symyx Software. Integrating ACD/Labs applications into Symyx Draw promotes a powerful set of tools from a valued partner while improving the day-to-day efficiency and productivity of researchers. This important development illustrates how Symyx partners are bringing interesting and valuable functionality to researchers.
