Fw: CCL:Calculation of LogP, logD, pKa and solubility

There are a number of other companies that do produce modules for LogP and
 pKa prediction. LogD integrated prediction is a lot harder to come by. The
 ACD integrated suite certainly has one of the largest install bases and
 fastest development curves for these types of tools and there are many
 comparisons regarding ACD and other software results for LogP and pKa at
 the web site. From your letter the desktop interfaces seem strong compared
 to your needs and you may want to consider using the BATCH modules. There
 are three different versions of the batch software, compiled for three
 different operating systems.  In addition, the modules
 that are available depend on the platform.
 Windows               SGI                Sun Solaris
 pKa                   pKa                pKa
 LogP                  LogP              LogP
 LogD                  LogD              LogD
 The SGI and SOlaris compilations maybe more appropriate for your needs as
 these have already been used for the purposes you suggest below.
 Also...to clarify....the logD module you refer to for $19,900 is actually a
 compilation of SIX integrated programs.
 1) Desktop LogP predictor with DB of 1000s of structures PLUS ability to
 train the database with your structures
 2) Desktop pKa predictor with DB of 1000s of structures
 3) Integrated LogD predictor using LogP and pKa tools
 4) Batch LogP predictor
 5) Batch pKa predictor
 6) Batch LogD predictor
 Best wishes and good luck in your hunt!
