You can save an experiment using the File Save option and open an existing experiment with the File Open command.
Relationships between inhibition constants and fractional inhibitions in enzyme-catalyzed reactions with different numbers of reactants, different reaction mechanisms, and different types of mechanisms of inhibition. Accuracy of measurement and biological variability.

Using the Program 33 Examples of the manual entry pages: The following examples are based around the sample2. The Dose-reduction Index of Chou The dose-reduction index DRI is a measure of how much the dose of each drug in a synergistic combination may be reduced at a given effect level compared with the doses for each drug alone. The m can be readily determined by the slope of the median-effect plot of Chou Glossary, Symbols and Definitions 59 In a higher order system such as life cells or animals, the situations are more complex. M, mM or IU can be combined and the results analyzed as usual. Most of the current therapies against cancer, and also those against immune diseases or viral infections, consist of empirically designed combination strategies, combining a variety of therapeutic agents.ĭata should be in the form of a tab separated. This will open the manual drug entry dialog box shown below. For each drug in the set there are two lines of data: Several attempts have been made to quantitatively measure the dose-effect relationship calcsyn each drug alone and its combinations and to determine whether a given combination would gain a synergistic effect. Pyrethins Data points entered: The entire grid will be exported. Several relevant points need to be considered: By using the enzyme kinetic models of the mass-action law, Chou derived and reported several hundred equations for different numbers of substrates, products, reaction sequences, and different types of inhibitions A new look at a very ca,cusyn problem.

In conclusion, CalcuSyn is an efficient piece of software which can help people in creating new mixed drug treatment and more effective ones. Whether synergy is treatment schedule dependent or combination ratio dependent? Step 7 – Click OK and the drug will be added to the experiment and shown in the contents pane.
This and the other sample files, called sample2. The primary aim is a mutual enhancement of the therapeutic effects, while other benefits may include decreased side effects and the delay or prevention of drug resistance. CalcuSyn for Windows, Multiple-drug dose-effect analyzer and manual. Manual and Software, Biosoft, Cambridge, U.K., Chou, T.-C. and antagonism, respectively (Source: CalcuSyn manual, Biosoft, ). combination-index data generated by CalcuSyn software analyses. 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.
