Flutafuranol
Flutafuranol, also called 18F-AZD4694 or 18F-NAV4694, is a fluorine-18 benzofuran PET radiotracer for brain beta-amyloid plaques, developed by AstraZeneca, with Kd 2.3 nM, low white matter binding, and near-identical imaging to 11C-PiB; used in research, not approved.
Flutamide
Flutamide (Eulexin) is a first-generation nonsteroidal antiandrogen, FDA approved in 1989 for prostate cancer. It competitively blocks the androgen receptor via its active metabolite 2-hydroxyflutamide, is used at 750 mg/day in combined androgen blockade, and carries a boxed warning for fatal hepatotoxicity.
Flute
The flute is a side-blown woodwind sounded when the player's air jet strikes the edge of the embouchure hole, with no reed; Theobald Boehm redesigned its key system.
Flutemetamol
Flutemetamol, sold as Vizamyl, is a radioactive diagnostic agent injected intravenously for brain PET imaging that estimates amyloid beta plaque density in adults with cognitive impairment.
Fluticasone furoate
Fluticasone furoate (FF) is a synthetic trifluorinated corticosteroid, a stable ester of fluticasone propionate, used once daily for asthma (Arnuity, Breo/Relvar Ellipta) and allergic rhinitis (Avamys), with very low systemic bioavailability.
Fluticasone propionate
Fluticasone propionate (FP, Flovent, Flonase, Cutivate, Xhance) is a trifluorinated androstane corticosteroid with 0.5 nmol/L glucocorticoid receptor affinity, used for asthma, rhinitis, sinusitis, and dermatoses; first US approval 1990, first Flovent generic 2026.
Fluting (firearms)
Fluting in firearms is the machining of longitudinal or spiral grooves into the exterior of a rifle barrel, most commonly to reduce its weight without shortening it, in straight, spiral, or custom styles.
Flutolanil
Flutolanil (Moncut, NNF-136) is a systemic SDHI fungicide developed by Nihon Nohyaku, registered in Japan in 1985, targeting Rhizoctonia solani in rice, peanuts, potatoes, and turf via mitochondrial Complex II inhibition.
Flutriafol
Flutriafol is a systemic triazole fungicide, introduced by ICI in 1983, that inhibits fungal sterol biosynthesis and controls cereal leaf diseases and embryo-borne bunts and smuts in crops like corn.
Flutrimazole
Flutrimazole (Micetal) is a topical imidazole antifungal, C22H16F2N2, ATC D01AC16, inhibiting lanosterol 14-alpha-demethylase; used as 1% cream, gel, powder, or solution against dermatophytes, Candida, and other fungi.
Flutter (software)
Flutter, also known as Google Flutter, is an open source cross-platform user interface toolkit written in Dart that builds iOS, Android, web, and desktop apps from a single codebase.
Flutter analysis
Flutter analysis is the aeroelastic method predicting self-excited oscillations of wings and structures from aerodynamic, elastic, and inertial forces, giving the critical speed for aircraft certification.
Flutter Entertainment
Flutter Entertainment, also known as Paddy Power and Betfair, is a global online sports betting and iGaming company. Formed in 2016, it operates diverse brands and trades on the NYSE.
Fluttershy
Fluttershy is a yellow Pegasus pony in My Little Pony: Friendship Is Magic (2010), the shy Element of Kindness voiced by Andrea Libman, with a three-butterfly cutie mark, a cottage near the Everfree Forest, and a gift for calming animals; she reformed Discord and later taught at the School of Friendship.
Flutterwave
Flutterwave is an African payments-technology company founded in 2016, headquartered in San Francisco with its main base in Lagos, which had processed over $40 billion in payments by 2026.
Fluvastatin
Fluvastatin, sold originally as Lescol, is a synthetic statin that lowers blood cholesterol by blocking HMG-CoA reductase; approved in the US in 1993, it was the first entirely synthetic statin.
Fluvisols
Fluvisols are young soils formed in recent river, lake, and marine deposits in floodplains, deltas, and tidal marshes, classified by stratified sediment and irregular organic matter renewed by periodic flooding, covering about 350 million hectares.
Fluvius
Fluvius, the operating name of Fluvius System Operator cvba, is the Belgian multi-utility network company that manages electricity, gas, and heat distribution in all 300 Flemish municipalities.
Fluvoxamine
Fluvoxamine (Luvox) is an SSRI antidepressant approved in the US in 1994 for obsessive-compulsive disorder and used for social anxiety disorder; a strong CYP1A2 inhibitor whose 2021 COVID-19 emergency use authorization request was declined by the FDA.
Flux
Flux, also called flow density, is the surface integral of a vector field's perpendicular component through a surface, underlying Gauss's law and Faraday's law of induction.
FLUX (AI model)
FLUX is a family of text-to-image and image-editing models built on flow matching by Black Forest Labs, first introduced in August 2024 with the FLUX.1 release.
Flux (metabolism)
Metabolic flux is the rate molecules pass through a biochemical pathway, measured by isotope tracing and 13C-MFA, quantified via stoichiometric models, and controlled per metabolic control analysis flux control coefficients.
Flux (metallurgy)
Flux, in metallurgy, is a material such as limestone or silica added to a furnace, crucible, or weld pool to combine with impurities and form a removable slag.
Flux (text-to-image model)
Flux is a family of text-to-image models developed by Black Forest Labs, a company founded by former Stability AI researchers, first released on August 1, 2024.
Flux balance analysis
Flux balance analysis (FBA) is an optimization method using linear programming on genome-scale metabolic networks to predict reaction fluxes, growth rates, and knockout phenotypes without kinetic parameters.
Flux calibration
Flux calibration is the observational procedure in astronomy that converts raw detector counts into physical flux units by comparing observations of standard sources with the science target.
Flux compactification
Flux compactification is a string theory construction in which extra dimensions form a compact manifold threaded by form-field fluxes that stabilize the moduli, as in KKLT.
Flux density
Flux density is the amount of a quantity passing through a unit area, especially magnetic flux density B, the measure of magnetic field strength in teslas.
