Drug Discovery: Overview01:26

Drug Discovery: Overview

10.3K
Drug discovery is a multifaceted process involving extensive screening, testing, and optimization of lead compounds to identify potential new drugs for therapeutic use. It combines several approaches, including screening large numbers of natural products, chemical modification of known active molecules, identification of new drug targets, and rational design based on biological mechanisms and drug-receptor structure. These approaches are carried out in both academic research laboratories and...

Genome-wide Association Studies-GWAS

14.8K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

Structure-Activity Relationships and Drug Design

1.3K
Drug design is a dynamic field that involves discovering and developing new medications based on specific biological targets. This process heavily relies on structure-activity relationships (SAR) and quantitative structure-activity relationships (QSAR) to guide the design and optimization of efficient drugs.
SAR studies the intricate relationship between a drug's chemical structure and biological activity. It focuses on understanding how modifications to a drug's structure can influence...

Osteoclasts in Bone Remodeling01:31

Osteoclasts in Bone Remodeling

3.5K
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during...

Drug Nomenclature01:17

Drug Nomenclature

2.6K
During the development of a new pharmaceutical, the manufacturer initially assigns a code name to the drug. Once approved, the drug receives a United States Adopted Name (USAN)—a generic, nonproprietary designation. Upon being listed in the United States Pharmacopeia, this nonproprietary name becomes the drug's official name. Additionally, the manufacturer assigns a proprietary name or trademark, which serves as the brand name under which the drug is marketed. It is worth noting that...

Prescription, Nonprescription and Orphan Drugs

978
Prescription drugs require a prescription from a medical practitioner and can only be obtained from a pharmacy. They have many applications, including treating pain, anxiety, and hypertension.
The misuse and addiction to prescription drugs is a growing problem that can affect people of all age groups, specifically teenagers. This can happen when prescription medications are used in ways not intended by the prescriber, such as taking someone else's prescription or using medication for...

Area of Science:

  • Bioinformatics and computational biology
  • Genomics and molecular biology
  • Pharmacology and drug discovery

Background:

  • Osteoarthritis (OA) is a chronic joint disease causing pain and stiffness.
  • Current treatments, including NSAIDs, have limited efficacy.
  • Novel therapeutic targets and drugs are needed for OA management.

Purpose of the Study:

  • To identify potential genes and drugs associated with osteoarthritis using bioinformatics.
  • To explore new therapeutic strategies for OA through data mining and analysis.

Main Methods:

  • Text mining to identify OA and NSAID-related genes.
  • Gene ontology (GO), KEGG pathway, and protein-protein interaction (PPI) network analysis.
  • Quantitative real-time polymerase chain reaction (qRT-PCR) for gene expression validation.
  • Drug Gene Interaction Database query for drug discovery.

Main Results:

  • Fifteen genes showed significantly increased expression in OA samples.
  • Eight of these genes are targeted by 53 drugs.
  • Twenty-one existing OA drugs and 32 novel drugs (FDA-approved for other conditions) were identified.

Conclusions:

  • Identified 15 genes and 32 potential drugs for improving OA treatment.
  • Highlighted opportunities for drug repositioning and novel target pharmacology in OA.
  • The study provides a foundation for developing new therapeutic strategies for osteoarthritis.
