Drug Discovery: Overview01:26

Drug Discovery: Overview

12.4K
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...

Prescription, Nonprescription and Orphan Drugs

1.3K
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...

Pharmaceutical Alternatives: Stability-Related Therapeutic Nonequivalence

233
Generic intravenous (IV) drugs are considered bioequivalent to their branded counterparts due to their 100% bioavailability upon administration. However, variations in stability among different drug products can significantly influence their therapeutic performance, even if they are pharmaceutically equivalent.Cefuroxime, a prophylactic antimicrobial, is often used as a single-dose IV injection for patients undergoing coronary artery bypass grafting surgery. A 3 g dose typically provides...

Combined Effects of Drugs: Synergism

7.1K
Synergism is a useful mechanism where combining two or more drugs is more effective than each constituent used alone. Such combinations are also called supra-additive interactions. The drugs collectively enhance the final therapeutic effect by acting on different targets. Another advantage is that the low dose of each constituent drug is sufficient to achieve the desired effect. This helps reduce the duration of therapy and lower the adverse effects of these drugs.
Such synergistic combinations...

Pharmaceutical Alternatives: Polymorphic Form-Related and Particle Size-Related Therapeutic Nonequivalence

209
Changes in polymorphic forms can significantly influence the bioavailability of poorly soluble drugs. Although the FDA defines pharmaceutical equivalence based on having the same active ingredient, dosage form, and route of administration, it does not automatically disqualify products with different polymorphic forms. This means two products with different polymorphs can still be deemed pharmaceutically equivalent. However, polymorphic differences can affect properties like wettability,...

Chirality in Nature02:30

Chirality in Nature

17.4K
Chirality is the most intriguing yet essential facet of nature, governing life’s biochemical processes and precision. It can be observed from a snail shell pattern in a macroscopic world to an amino acid, the minutest building block of life. Most of the snails around the world have right-coiled shells because of the intrinsic chirality in their genes. All the amino acids present in the human body exist in an enantiomerically pure state, except for glycine - the sole achiral amino acid.

Área de la Ciencia:

  • Endocrinología y Biología del Cáncer
  • Mecanismos moleculares de la progresión del cáncer de próstata
  • Metabolismo de hormonas esteroides

Sus antecedentes:

  • La vía de señalización de andrógenos es crucial para la progresión del cáncer de próstata y los procesos fisiológicos normales.
  • Los andrógenos potentes como la testosterona y la dihidrotestosterona activan el receptor de andrógenos (AR).
  • La reactivación del AR en el cáncer de próstata resistente al tratamiento resalta la importancia de la vía.

Objetivo del estudio:

  • Revisar la serie de descubrimientos en el metabolismo de andrógenos del grupo de autores.
  • Proporcionar una narrativa mecanicista de los hallazgos de la investigación, incluidos los descubrimientos accidentales y el refinamiento de hipótesis.
  • Iluminar elementos clave del metabolismo de los andrógenos, centrándose particularmente en los carbonos 3, 5 y 17 de la columna vertebral de esteroides.

Principales métodos:

  • Revisión narrativa mecanicista de investigaciones publicadas y no publicadas.
  • Enfoque en el refinamiento de hipótesis basado en datos tras los hallazgos iniciales.
  • Análisis del metabolismo de esteroides, apuntando específicamente a las posiciones C3, C5 y C17 de la columna vertebral de esteroides.

Principales resultados:

  • Los procesos metabólicos de esteroides que regeneran andrógenos potentes en los tejidos del cáncer de próstata impulsan la resistencia al tratamiento.
  • El bloqueo de la síntesis de andrógenos no gonadales (por ejemplo, con abiraterona) proporciona un beneficio de supervivencia, lo que confirma el papel de estos procesos.
  • Se han dilucidado conocimientos detallados sobre el metabolismo de carbonos específicos (C3, C5, C17) dentro de la columna vertebral de esteroides.

Conclusiones:

  • El metabolismo de los andrógenos juega un papel crítico en el desarrollo del cáncer de próstata resistente al tratamiento.
  • La comprensión de estas vías metabólicas es esencial para desarrollar estrategias terapéuticas más efectivas.
  • La investigación destaca la compleja interacción entre la señalización de andrógenos, el metabolismo y la progresión del cáncer.
