Drug Delivery: Overview01:16

Drug Delivery: Overview

345
The selection of a drug's delivery route depends upon its physicochemical properties, including lipid or water solubility and ionization, as well as the therapeutic requirement, such as immediate or sustained effect. These routes can be divided into three primary categories: enteral, parenteral, and topical.
Enteral delivery involves administering drugs directly through swallowing, sublingual placement, or buccal application. Orally administered drugs predominantly navigate the...

Principles of Drug Action

6.2K
Drugs are chemical substances that modify biological responses by interacting with macromolecular targets such as receptors, ion channels, transporters, and enzymes. Pharmacodynamics describes the course of action of drugs leading to the physiological effect at a specific site in the body.
Drugs can be agonists or antagonists. Like the endogenous ligands, agonists always bind and activate the target to produce a cellular response. Agonist binding induces a conformational change which in turn...

Prodrugs01:30

Prodrugs

2.7K
Prodrugs are a class of pharmaceutical compounds that undergo a biotransformation process within the body to be converted into a pharmacologically active drug. Prodrugs are designed to improve the therapeutic properties of the parent drug, such as enhancing bioavailability, increasing stability, or reducing toxicity. The concept of prodrugs revolves around modifying the chemical structure of the original drug to make it more effective or convenient for administration.
Prodrugs help overcome...

Targets for Drug Action: Overview

6.7K
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...

Factors Influencing Drug Absorption: Physicochemical Parameters

345
The physicochemical characteristics of drugs play a crucial role in formulating stable and bioavailable drug products. The solubility of a drug, governed by the varying pH along the GI tract and its dissociation constant (pKa), is pivotal in determining its ionization state and absorption rate. Notably, weak acids and bases remain unionized and are absorbed more rapidly.
Enhanced drug absorption can be achieved by reducing particle sizes and increasing surface areas, thereby facilitating...

Drug-Receptor Bonds01:25

Drug-Receptor Bonds

3.0K
Drug-receptor bonds are formed through various chemical forces when drugs interact with target cells. Covalent bonds, strong and irreversible, are exemplified by DNA-alkylating anticancer agents that inhibit cell division. However, such irreversible drug binding lacks selectivity and can modify the DNA of the surrounding healthy cells. Covalent binding often contributes to tissue toxicity, as seen with chloroform and paracetamol metabolites binding to the liver, causing hepatotoxicity.

Area of Science:

  • Carbohydrate Chemistry
  • Medicinal Chemistry
  • Pharmacology

Background:

  • Glycodrugs, a significant class of chemical medicines, originate from biological carbohydrates and their analogs.
  • The underlying principles and defining characteristics of glycodrugs remain incompletely understood.
  • A clear framework is needed to elucidate the functional roles of glycodrugs in therapeutic applications.

Purpose of the Study:

  • To define and delineate the fundamental logic and key features of glycodrugs.
  • To establish a foundational understanding for the development of novel glycomedicines.

Main Methods:

  • Extraction and analysis of four critical characteristics defining glycodrugs.
  • Categorization of glycodrugs based on their core chemical components (e.g., glucose, ribose, N-acetylneuraminic acid).
  • Evaluation of glycodrugs' roles in metabolic pathways, signaling processes, and pathogen interactions.

Main Results:

  • Glycodrugs related to glucose (Glc) are identified as crucial regulators of glycometabolism.
  • Drugs involving ribose (Rib), glucosamine/galactosamine (GlcN/GalN), and sialic acid (Sia) effectively modulate cellular signaling.
  • Glycodrugs incorporating rare sugars demonstrate efficacy against diverse pathogens.
  • Glycosylation modifications are confirmed as a valuable strategy for enhancing drug properties (druggability).
