Parachor is the molecular weight of a liquid times the fourth root of its surface tension, divided by the difference between the density of the liquid and the density of the vapor in equilibrium with it; essentially constant over wide ranges of temperature. Predictions are based on mechanistic models that use a number of physicochemical parameters, including lipophilicity and ionization, as inputs. Advanced Chemistry Development, Inc. Its function has been associated with the drugs' absorption, distribution, excretion, CNS effects, multidrug resistance MDR. While prediction cannot replace experimentation, this module allows compounds to be ranked according to their passive transport across the BBB, based on the following information:

Read how Percepta helps chemists and formulators work more efficiently, and assists in decision-making. The boiling point at a pressure of 1 atmosphere is suitf the normal boiling point.
Molar Refraction is the equation for the refractive index of a compound modified by the compound's molecular weight and density. Also called formula weight or molecular mass. Ready to learn more?
Simple Structure Advanced History. Model training and application of training data does not require an understanding of programming and is easily accessible and phydchem. Contact Us for More Information.
Absolv Module The Absolv prediction module calculates Abraham solvation parameters from structure.
The term is applicable to mixtures and pure substances and to matter in the solid, liquid, gaseous, or plasma state. Molar Volume is the volume occupied by one mole of a substance in the form of a solid, liquid, or gas.
Some implementations of FRB also exclude additional bonds from the FRB count, so don't be surprised if you get three different results for FRB from three different vendors. Resulting from a collaboration with the FDA, this module offers insights into 21 toxic endpoints reflecting various mechanisms of hazardous activity including:.
Train with experimental data —better reflect proprietary chemical space and improve prediction accuracy using inbuilt machine learning capabilities.
PhysChem, ADME & Toxicity Calculations with Percepta Software
Irritation Module Calculates the potential of a compound to cause moderate or stronger eye and skin irritation as per the Draize test. KNIME integration components available. LD 50 in mice after oral administration LD 50 in mice after intravenous administration LD 50 in mice after intraperitoneal administration LD 50 in mice after subcutaneous administration LD 50 in rats after oral administration LD 50 in rats after intraperitoneal administration Estimates qualitative OECD Hazard categories The expert system identifies hazardous substructures potentially responsible for the toxic effect.
Easily evaluate results from physicochemical, ADME, and toxicity calculators—each module offers prediction—specific information and tools such as structure highlighting and calculation protocols.
. Acd/physchem Suite
Capability to assess prediction reliability and accuracy—no calculator will give perfect results for every compound. The behavior of a molecule in the human body, or any environment, is governed by the molecular properties of that structure.
Also known as molal volume; mole volume. Common units of density are grams per cubic centimeter, and slugs or pounds per cubic foot. Other PhysChem Descriptors Molecular property calculators are also available for the following: The Boiling Point scd a liquid is the temperature at which the liquid and vapor phases are in equilibrium with each other at a specified pressure.
Toxicity prediction helps scientists assess potential risk. PK Explorer Module Estimates a number of parameters determining the pharmacokinetic profile of your compounds by using a set of differential equations from a multi-compartment model describing the organism of an average statistical human: Log P Module Calculate log P lipophilicity from structure.
Health Effects Module Predicts the probable adverse effects of a compound on particular organs or organ systems based on long term organ specific toxicity studies encompassing various species and routes of administration The following organs and organ systems are considered: Software installations for individual computers with a graphical user interface. Passive permeability across jejunal epithelium, also indicating absorption rate.
The Flash Point is the lowest temperature at which the vapor of a combustible liquid can be made to ignite momentarily in air. Our expertise lies in vendor-neutral spectroscopic data processing and prediction, physicochemical and ADMET property prediction, analytical knowledge management, interactive reporting, and integrating analytical data with chemical structures to help protect and leverage valuable research knowledge.
Its function has been associated with the drugs' absorption, distribution, excretion, CNS effects, multidrug resistance MDR.
Plug-in to corporate intranets or workflow tools such as Pipeline Pilot. Why use molecular property calculators puyschem predictors? The CYP Regioselectivity model is able to provide valuable insights into a compound's metabolic profile early in the drug discovery process when little or no experimental information is available, and labor intensive investigation of each compound in the screening process is prohibited by the large number of compounds involved.
Screen tens of thousands of compounds with minimal user intervention—compatible with Microsoft Windows and Linux operating systems OS.
