New in 2012 through 2020
August 2012: ChemicaElectrica Gateway is released for the
first time replacing the ChemicaElectrica Database. New features
include a 3-d drawing program with the MM2 minimizer and MOPAC geometry
optimization, substructure and similarity searching, internet
connectivity and flexible menus. A new low price is also introduced for
this product. See our ChemicaElectrica Gateway
web page for details.
September 2012:
To ChemicaElectrica database added the following:
Added sodium bisulfite and related. Added some sugars and sweeteners.
Added sulfur oxides. Updated all pesticides in ChemicaElectrica
database.
Added rule of five calculations to ChemicaElectrica capabilities.
December 2012:
Added household products database to ChemicaElectrica database.
Upgraded dimensions routine in MMP and MMP+. Added upgraded dimensions routine to ChemicaElectrica.
January 2013:
Added new automatic molecule with molecule interaction routines to MMP+.
Bug fixed to substructure search routine in Drawing Window (Database window working fine.)
ChemicaElectrica Version 2.3 released.
February 2014:
Added new drugs with USAN names through mid-February to ChemicaElectrica
database. Added compounds on EPA list of safer ingredients to
ChemicaElectrica database. Compound count now over 9000.
ChemicaElectrica Version 2.3.1 released.
December 2014:
Added new drugs with USAN names through November to ChemicaElectrica database. Compound count now over 10000.
MMP+ Version 7.0 released
February 2016:
Added new drugs with USAN names through December 2016 to ChemicaElectrica database. Compound count now about 10400.
March 2017:
Added new drugs with USAN names through December 2017 to ChemicaElectrica database. Compound count now about 10700.
December 2017. Version 8 released.
New Features:
Added new method for automated generation of substructure fragment QSAR models
Go here for details.
Improved the Stepwise Regression Model
New proprietary methods for boiling point, log Kow and specific gravity
Brute force regression: added ability to subset by molecular weight
Brute force regression: added ability to subset by organic atom types only
Changed output of Surfactant property routine to Notepad
Added molecular similarity comparison to output of Surfactant property routine
Added vanKrevelen method for MR and dielctric constant calculation to Polymer calculation routine
Added ability to calculate 3-D structures from canonical SMILES notation (File menu)
Fixed severe bug in the Surfactant property routine when more than one molecule drawn
March 2018. Version 8.1 of MMP released.
The substructure fragment QSAR modeler has new features: a) added an option to calculate cross-products and squares of the independent variables; b) added option to divide all significant independent variables by each other; c) added the ability to go back and forth iteratively through the different features of the model.
These same new features were added to the Stepwise Regression Modeler.
A new community sharing web page was made for sharing models made with the Automated substructure modeler.
ChemicaElectrica was updated. There are over 11,000 molecules in the database now.
May 2018: Added the ability to shell in the IUPAC InChI string creation program with the structure drawn in MMP passed to the program. Included the IUPAC open source program in the distribution ( access from the MMP 8.1 Calculate menu)
December 2018: A new model of the critical packing parameter (CPP) is included. It is described HERE.
March 2019: MMP+ version 8.2 and ChemicaElectrica Gateway version 4.0 are launched. The format of the ChemicaElectrica database was changed from an older version of ACCESS to XML. The reason for this is that after loading the current 64 bit version of ACCESS, ChemicaElectrica would no longer load. There are minor improvements and bug fixes in MMP+ as well.
January 2020: Updated ChemicaElectrica database with all pharmaceuticals approved in 2019
June 2021: MMP+ version 9 is launched. Added new atom based automated model generation. ChemicaElectrica database updated.
June 2021: MMP Flavor+ version 9 is launched. Updated program to contain new features of MMP+.
