Protéine du rétinoblastomeLa protéine du rétinoblastome (pRB) est une protéine de séquestration qui exerce un contrôle négatif du cycle cellulaire. Cette fonction est essentielle dans les organismes pluricellulaires pour éviter la formation de tumeurs malignes qui mettraient en péril l’organisme, ce qui permet de qualifier cette protéine de « suppresseur de tumeur ». Son nom vient de son étroite collaboration dans un cancer ophtalmologique pédiatrique : le rétinoblastome.
Virtual screeningVirtual screening (VS) is a computational technique used in drug discovery to search libraries of small molecules in order to identify those structures which are most likely to bind to a drug target, typically a protein receptor or enzyme. Virtual screening has been defined as "automatically evaluating very large libraries of compounds" using computer programs. As this definition suggests, VS has largely been a numbers game focusing on how the enormous chemical space of over 1060 conceivable compounds can be filtered to a manageable number that can be synthesized, purchased, and tested.
Secondary treatmentSecondary treatment (mostly biological wastewater treatment) is the removal of biodegradable organic matter (in solution or suspension) from sewage or similar kinds of wastewater. The aim is to achieve a certain degree of effluent quality in a sewage treatment plant suitable for the intended disposal or reuse option. A "primary treatment" step often precedes secondary treatment, whereby physical phase separation is used to remove settleable solids.
High-content screeningHigh-content screening (HCS), also known as high-content analysis (HCA) or cellomics, is a method that is used in biological research and drug discovery to identify substances such as small molecules, peptides, or RNAi that alter the phenotype of a cell in a desired manner. Hence high content screening is a type of phenotypic screen conducted in cells involving the analysis of whole cells or components of cells with simultaneous readout of several parameters.
Conception de médicamentLa conception de médicament, plus précisément conception de substance pharmacologiquement active plus connue sous sa dénomination anglaise Drug design est l'ensemble des processus nécessaires à l'élaboration d'un médicament. Dans l'industrie pharmaceutique, ces processus peuvent-être subdivisés et répartis en quatre phases ou étapes : La phase de recherche La phase de développement La phase clinique La phase de mise sur le marché Remarque : Les phases de recherche et développement sont communément dénommées R&D.
Drug discoveryIn the fields of medicine, biotechnology and pharmacology, drug discovery is the process by which new candidate medications are discovered. Historically, drugs were discovered by identifying the active ingredient from traditional remedies or by serendipitous discovery, as with penicillin. More recently, chemical libraries of synthetic small molecules, natural products or extracts were screened in intact cells or whole organisms to identify substances that had a desirable therapeutic effect in a process known as classical pharmacology.
Food and Drug AdministrationLa Food and Drug Administration (FDA, en français : « Agence fédérale américaine des produits alimentaires et médicamenteux ») est l'administration américaine des denrées alimentaires et des médicaments. Cet organisme a, entre autres, le mandat d'autoriser la commercialisation des médicaments sur le territoire des États-Unis.
Approved drugAn approved drug is a medicinal preparation that has been validated for a therapeutic use by a ruling authority of a government. This process is usually specific by country, unless specified otherwise. In the United States, the FDA approves drugs. Before a drug can be prescribed, it must undergo the FDA's approval process. While a drug can feasibly be used off-label (for non-approved indications), it still is required to be approved for a specific disease or medical condition.
Club drugClub drugs, also called rave drugs or party drugs, are a loosely defined category of recreational drugs which are associated with discothèques in the 1970s and nightclubs, dance clubs, electronic dance music (EDM) parties, and raves in the 1980s to today. Unlike many other categories, such as opiates and benzodiazepines, which are established according to pharmaceutical or chemical properties, club drugs are a "category of convenience", in which drugs are included due to the locations they are consumed and/or where the user goes while under the influence of the drugs.
Drug deliveryDrug delivery refers to approaches, formulations, manufacturing techniques, storage systems, and technologies involved in transporting a pharmaceutical compound to its target site to achieve a desired therapeutic effect. Principles related to drug preparation, route of administration, site-specific targeting, metabolism, and toxicity are used to optimize efficacy and safety, and to improve patient convenience and compliance. Drug delivery is aimed at altering a drug's pharmacokinetics and specificity by formulating it with different excipients, drug carriers, and medical devices.
