Mechanistic Models: Overview of Compartment Models

Mechanistic Models: Overview of Compartment Models

Mechanistic models, a category encompassing both physiological and compartmental modeling, differ from empirical models' approaches to incorporating known factors about the systems being modeled. Empirical models describe data with minimal assumptions, while mechanistic models aim to provide a robust description of available data by specifying assumptions and integrating known factors about the system. Compartmental analysis is a key example of a mechanistic model in pharmacokinetics and...

Model Approaches for Pharmacokinetic Data: Compartment Models

Model Approaches for Pharmacokinetic Data: Compartment Models

Compartmental analysis is a widely adopted approach to characterizing drug pharmacokinetics. It uses compartment models that conceptualize the body as a collection of reversibly communicating compartments, each representing a group of tissues exhibiting similar drug distribution characteristics. The movement rate of the drug between these compartments is typically described by first-order kinetics.
Two primary types of compartment models are recognized: mammillary and catenary. The more...

Multicompartment Models: Overview

Multicompartment Models: Overview

Multicompartment models are mathematical constructs that depict how drugs are distributed and eliminated within the body. They segment the body into several compartments, symbolizing various physiological or anatomical areas connected through drug transfer processes such as absorption, metabolism, distribution, and elimination.
These models offer a more comprehensive representation of drug behavior in the body than one-compartment models. They accommodate the complexity of drug distribution,...

Physiological Pharmacokinetic Models: Incorporating Hepatic Transporter-Mediated Clearance

Physiological Pharmacokinetic Models: Incorporating Hepatic Transporter-Mediated Clearance

Drug transporters are critical in drug absorption, distribution, and excretion processes. They should be included in physiological-based pharmacokinetic (PBPK) models, which help predict human drug disposition. However, predicting this is challenging during drug development, especially when liver transport is involved. However, with a realistic representation of body transport processes, an accurate model may be possible.
A recent model describes pravastatin's hepatobiliary excretion, mediated...

Pharmacodynamic Models: Overview

Pharmacodynamic Models: Overview

Pharmacodynamic (PD) responses describe the interaction between a drug and its biological target, culminating in a physiological effect. These responses can be classified into different types: continuous variables, such as blood glucose levels; categorical outcomes, like survival rates; and time-to-event metrics, such as disease progression. Understanding and modeling PD responses are critical for optimizing drug efficacy and safety.PD models describe the relationship between drug concentration...

Model Approaches for Pharmacokinetic Data: Physiological Models

Model Approaches for Pharmacokinetic Data: Physiological Models

Physiological models in pharmacokinetics are instrumental in understanding the distribution and elimination of drugs within the body. These models describe the drug concentration within target organs, influenced by factors such as drug uptake, tissue volume, and blood flow. Drug uptake is governed by the partition coefficient, which signifies the drug concentration ratio in tissue to that in the blood. The blood flow rate to a specific tissue is expressed as Qt, and the rate of change in tissue...

Background:

Online databases contain vast molecular interaction and pathway data.
Modeling software facilitates simulation of biological pathways.
Discrepancies between pathway data standards (BioPAX) and model exchange standards (SBML) hinder data integration.

Purpose of the Study:

To introduce a novel bridging format, Systems Biology Pathway Exchange (SBPAX), for integrating diverse pathway data.
To overcome limitations in automated conversion between BioPAX and SBML formats.
To provide a flexible framework for managing and merging molecular interaction data from multiple sources.

Main Methods:

Developed SBPAX as an intermediate format for data conversion.
Implemented conversion strategies using one-to-one mappings to and from SBPAX.
Utilized SBPAX for data repository, documentation of conversion assumptions, data "gluing", and merging.

Main Results:

SBPAX facilitates practical and less erroneous conversion between BioPAX and SBML.
The format allows for flexible descriptions of essential pathway components (processes, substances, locations).
SBPAX acts as a central platform for managing and integrating heterogeneous molecular pathway information.

Conclusions:

SBPAX significantly improves the integration of molecular pathway knowledge and models.
The proposed approach enhances the automation and reliability of cross-format data conversion.
SBPAX provides a robust solution for consolidating and harmonizing systems biology data.
