Drugs that Destabilize Microtubules

4.3K
Microtubules are dynamic structures and can be regulated by microtubule targeting agents (MTAs). Microtubule destabilizing drugs are a class of MTAs that destabilize and prevent microtubules' polymerization. Both natural and synthetic chemicals can be found under this class of drugs. Vincristine and vinblastine, two vinca alkaloids, and colchicine were among the first to be discovered. These drugs can affect cells in various ways, either by inducing a change in cell morphology, preventing...

Targets for Drug Action: Overview

11.2K
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...

Drugs that Stabilize Microtubules

2.9K
Microtubules are dynamic structures that undergo cycles of catastrophe and rescue. The microtubules play a central role in cell division by forming the spindle apparatus for segregating the chromosomes. This makes them ideal targets for regulating dividing cells in tumors and malignant cancer cells. Microtubule stabilizing drugs help stabilize the microtubule formation and promote its polymerization. Paclitaxel was the first microtubule stabilizing agent used as anticancer drug in chemotherapy...

  • Nanomedicine
  • Drug Delivery Systems
  • Supramolecular Chemistry

Background:

  • Nanomedicine leverages nanostructures for enhanced medical treatments and reduced side effects.
  • Traditionally, drugs were viewed only as cargo, not as structural components in nanomedicine.
  • The potential of drug molecules as building units for nanostructures was largely unexplored.

Purpose of the Study:

  • To review recent advances in using drug molecules as building units for nanomedicines.
  • To evaluate the opportunities presented by self-delivering supramolecular nanomedicines.
  • To explore the rational design of drug-based nanostructures for tailored delivery.

Main Methods:

  • Review of current literature on drug-based nanostructure formation.
  • Analysis of supramolecular assembly strategies utilizing drug molecules.
  • Evaluation of nanostructure morphologies and their administration routes.

Main Results:

  • Drug molecules can self-assemble into well-defined nanostructures (nanospheres, rods, nanofibers, nanotubes).
  • These drug-based nanostructures act as self-delivering systems with high, fixed drug content.
  • Rational design allows tailoring of nanostructure morphology and drug loading for specific delivery needs.

Conclusions:

  • Using drug molecules as building units represents a significant advancement in nanomedicine.
