CALCUSYN MANUAL PDF

年1月23日 CalcuSyn is a software tool whose main purpose is to aid individuals in analyzing mixed drug treatments, a more and more used practice in. combination-index data generated by CalcuSyn software analyses .. and antagonism, respectively (Source: CalcuSyn manual, Biosoft, ).

However, one should realize that an antagonistic action may be desired when toxicity is concerned, i. Directly into the raw data grid 2. In this case, the component combinations can also be determined for their synergism or antagonism e.

Three-dimensional isobols for three drug combinations: The combined effect predicted by the mass-action law principle. Command Line Import There are two different types of command-line import, both require a text file. Prerequisite Dose-effect Curves Each drug alone should have a dose-effect relationship. The errors of estimate can be from several sources, e. This is the second drug Dm The normalization allows the construction of isobolograms for each combination data point with different combination ratios i.

This approximates to a normal distribution for small values of SE Dm but this assumption may not be valid as the uncertainty in Dm increases. Dose-effect analysis with microcomputers: ADP-ribose Fraction affected uM 95 0. Text can be copied from the window and pasted into a spreadsheet or word processor for further formatting or processing.

Manuual design can be expanded to a large dose range or larger density. When report or graph windows are selected, the estimated errors will be added.

This will open the raw data import dialog that lets you import either files or ODBC data. This and the other sample files, called sample2. Click the Next button to proceed to the next page of the wizard.

Welcome to COMPUSYN

This term was first introduced by Chou and Talalay in 7. Nonetheless, it goes without saying that you still require some specialized knowledge in order to get around CalcuSyn.

EDisobol, EDisobol, EDisobol, etc A graph indicating the equipotent combinations of various doses; it can be used to illustrate additivity, synergism, or antagonism. When the grid is used, data can be processed through wizards which make the software easily accessible to new users.

Analysis of drug interactions.

You can add drugs to CalcuSyn manually or with the help of a wizard, so that you can be sure you do not forget to include certain information. Quantitative dose-effect manul and algorithms: It is usually depicted by ED50 or IC Graphs Graphs will show the certainty limits on the CI graph. Run the installation program, called setup.

Synergism at what dose level?

Computer Software

Most of the current therapies against cancer, and also mwnual against immune diseases or viral infections, consist of empirically designed combination strategies, combining a variety of therapeutic agents.

It is possible to generate isobolograms for three drug combinations as described by Chou and Chou 14, Using the Program 55 Data points entered: Double-click on Raw Data to open the raw data grid to enter drug data.

In a simple system such as enzyme or receptor, it is analogous to noncompetitive inhibition between two inhibitors.

Drug Import Example Data Below is an example formatted in the correct way. Academic Press, San Diego, CalcuSyn 10 The Median-Effect Principle The Median-effect Equation of Chou A general equation for dose-effect relationship was derived by Chou 1,2 through mathematical induction using hundreds of enzyme kinetic models. Worked examples The following reports show the summary results for all six examples included with CalcuSyn.

It can also be extended to multiple ratios e. Using this method, a combination index CI is calculated from drug cytotoxicity or growth inhibition curves.

The entire report will be exported. CalcuSyn 14 The advantages of the constant ratio design are: Already used in hundreds of janual labs and pharmaceutical companies, CalcuSyn is indispensable for the study of drug mixtures.
