Insights

Understanding chemoxenobiotic interactions with cells is key for predicting cancer treatment effectiveness. This study analyzes biophysical properties to classify xenobiotics for improved chemotherapy and personalized medicine.

Area of Science:

  • Biophysics
  • Computational Chemistry
  • Pharmacology

Background:

  • Accurate determination of chemoxenobiotic apoptotic potential in combination therapy requires understanding cellular interactions.
  • Predicting conserved biophysical properties is crucial for characterizing xenobiotic-cell interactions.

Purpose of the Study:

  • To develop a classification system for xenobiotics based on conserved biophysical properties.
  • To enhance the effectiveness of existing combination chemotherapy regimens.
  • To improve the predictive accuracy of personalized cancer treatment algorithms.

Main Methods:

  • Analysis of chemoxenobiotic structures, including atom distribution, octanol-to-water partition coefficient (Log OWPC), and van der Waals diameter (vdWD).
  • Determination of Log OWPC-to-vdWD, hydrophilic moiety-to-vdWD, and lipophilic moiety-to-vdWD parameters.
  • Characterization of cellular and sub-cellular interactions of xenobiotic chemotherapies.

Main Results:

  • A classification system for xenobiotics was developed based on predicted conserved biophysical properties.
  • Key parameters like Log OWPC-to-vdWD were determined for various chemoxenobiotics.
  • The study provides a framework for understanding xenobiotic-cell interactions at a biophysical level.

Conclusions:

  • The developed classification system aids in predicting the mode of chemotherapeutic effect.
  • Findings support improving combination chemotherapy efficacy and personalized cancer treatment.
  • The study facilitates the selection of novel xenobiotics for targeted delivery, such as via dendrimer nanoparticles.

Treatment Resistant Cancers02:56

Treatment Resistant Cancers

Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

Targets for Drug Action: Overview01:26

Targets for Drug Action: Overview

Drugs target macromolecules to modify ongoing cellular processes. Primary drug targets include receptors, ion channels, transporters, and enzymes.
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Cellular Membranes and Drug Transport01:24

Cellular Membranes and Drug Transport

Drugs must traverse multiple biological barriers, such as multi-layered skin, single-layered intestinal epithelium, and the plasma membrane, to reach their target sites within the body. The plasma membrane, a highly structured composite of phospholipids, carbohydrates, and proteins, is the cell's protective boundary, facilitating selective substance exchange.
Phospholipids arrange themselves into a bilayer, with hydrophilic heads oriented outward and hydrophobic tails facing inward.

Mechanisms of Drug Absorption: Paracellular, Transcellular, and Vesicular Transport01:23

Mechanisms of Drug Absorption: Paracellular, Transcellular, and Vesicular Transport

Drugs need to permeate cell membranes to reach their target sites after administration. Orally administered drugs must transcend intestinal epithelial membrane barriers to infiltrate the systemic circulation. Drugs with a molecular weight of less than 500 Daltons diffuse through gaps between neighboring cells, called paracellular pathways.
However, most drugs use the transcellular route, traversing directly through the cell membranes via two mechanisms: passive and active transport. Passive...

Pharmacogenetics of Drug Metabolism: Overview01:27

Pharmacogenetics of Drug Metabolism: Overview

Genetic polymorphism in drug metabolism is crucial to the inter-individual variability observed in drug responses. Drug metabolism primarily involves the chemical modification of drugs and other xenobiotics to enhance their elimination by increasing their polarity. Two main classes of enzymes mediate this biotransformation process: Phase I enzymes, primarily cytochrome P450s, catalyze oxidation and reduction reactions, while other enzymes, such as esterases, mediate hydrolysis, and Phase II...
