Chemdraw software

To solve this problem Telesystemes has designed in 1987 a DARC-Fl transfer format for both PCs and mainframe and also in 1987/1988, in cooperation with Janssen Pharmaceutica of Beerse, Belgium has developed an interface between DARC-SMS and the ChemDraw software produced by Cambridge Scientific Computing. During 1988 Telesystemes was developing PC/host software named D ARC-LINK 1. 

The authors also are indebted to Mrs. Phyllis Reid for her skills in desktop publishing, ChemDraw, and other computer software programs, but mostly for her perseverance and good humor during the many revisions of this book. Phyllis input has improved the quality of this product and her knowledge has allowed us to put the entire manuscript into an electronic format. 

The second important software advance was ChemDraw, which was released first for the Mac in 1986 [59-62]. This program gave chemists the ability to quickly create two-dimensional chemical diagrams. Every medicinal chemist...

Other structure-encoding schemas are developed by software vendors and academia such as Daylight Smiles, CambridgeSoft ChemDraw Exchange (CDX), and Chemical Markup Language (CML), and they all have advantages and disadvantages. The MDL CT File Format is the only one that is supported by almost all chemical informatics software vendors. 

Alternately, the commercial molecular modeling software programs such as ChemOffice (http //www.camsoft.com) can be used. The ISIS draw in sketch format (struname.skc) is first converted to ChemDraw format (struname.cdx), which is then transformed into 3D structure (struname.c3d) with Chem 3D (Chapter 14) and saved as PDB format (struname.pdb).

There are a handful of file formats, however, that can be opened in many different software packages. Drawing and scanning programs generally provide the option of saving to one or more of these formats. For example, ChemDraw and... 

ACS journals accept application files (native formats) for several common software programs, including. skc files from ISIS/Draw and. cdx files from ChemDraw. 

Supported stereochemical descriptors in computational software are, according to the Cahn-lngold-Prelog, (CIP) system E/Z for double bonds and R/S for asymmetric centers. Pseudoasymmetric centers are also recognized as descriptors r/s (e. g. 2,3,4-trihydroxyglutaric acid, see Fischer projection below) in ChemDraw 6.0. 

The entire manuscript was produced using ChemDraw , the remarkable software for drawing chemical structures developed by CambridgeSoft Corp., Cambridge, MA. We, the users of sophisticated software like ChemDraw, are the beneficiaries of the intelligence and creativity of the people in the computer industry. We are fortunate that they are so smart. 

MetaCore client software runs within a web browser and requires a PC or Macintosh computer (P4 equivalent CPU or better and 1 GB of RAM) with Internet Explorer 6.0, Mozilla Firefox 2.0, or Safari 3.0.4 or higher, Macromedia Flash Player 8 or higher, JRE 1.5.0, and ChemDraw ActiveX/Plugin Net 9.0. Download Edition are also required. MetaDrug requires a PC with IE 6.0 or higher.

With the exception of scanned figures, all drawings in this book were prepared using ChemDraw or Chem3D from CambridgeSoft. I thank them for providing the software that made this project possible. 

Another deficiency is that a single software package may not satisfy all requirements. Structures stored in MACCS may not be drawn in a preferred way, so a package like ChemDraw is used. The Switcher program was written because several packages may need to be used to get the desired result. The chemists requirements are severe, and we have not met them all. 

In the past few years, several microcomputer-based software packages have become available to input and store chemical structures. These packages can be divided into two main groups those that allow structures to be drawn and stored for later recall [e.g., ChemDraw (S. Rubenstein), WIMP (Aldrich)] and those that capture structures from online files like Index Chemicus Online and CAS ONLINE [e., PC-Plot (MicroPlot), Emu-Tek (FTG Data Systems)]. The greatest limitation of both groups of software is that stored structures have to be recalled serially or by specific registration number since structure and sub-structure search capabilities are not available. 

A final example in this category is ChemDraw (Stewart Rubenstein, Somerville, MA), which probably uses connection tables but does not have substructure searching or interfacing with other software. ChemDraw appears in this book see Chapter 3) because it is probably the most user-friendly package on the market for entering chemical structures and producing high-quality output. Unfortunately, it is available for use only on Apple Macintosh computers.
