Thinner (film)

Thinner is a 1996 American horror film based on the 1984 novel by Stephen King. It stars Robert John Burke as a lawyer cursed to lose weight uncontrollably.

Thinner (1984) is a horror novel Stephen King published as Richard Bachman via New American Library, in which cursed lawyer Billy Halleck wastes away after killing an old woman; its exposure led to King's unmasking and a 1996 film.

Thinopyrum

Thinopyrum (wheatgrasses), genus of perennial Triticeae grasses erected by Á.Löve in 1980 with about 15 species; wild relatives of wheat valued for salt-tolerance genes and domesticated as the perennial grain Kernza (Th. intermedium).

Thinspiration

Thinspiration (thinspo) is pro-eating-disorder imagery and text idealizing thinness to inspire weight loss, originating in pro-ana spaces and spreading to Tumblr, Instagram, and Twitter; platforms banned its hashtags in 2012, and research links exposure to body dissatisfaction and disordered eating.

Thio-LISICON

Thio-LISICON (thio-lithium superionic conductor) is a family of crystalline sulfide solid electrolytes for lithium batteries, introduced by Ryoji Kanno and coworkers in 2000 as the first crystalline sulfide electrolytes.

Thioacetal

A thioacetal is the sulfur analog of an acetal, formed from a carbonyl compound and a thiol, used as a protecting group and in umpolung synthesis.

Thioacetamide

Thioacetamide (ethanethioamide) is a thioamide, the sulfur analog of acetamide, used as an analytical reagent that releases hydrogen sulfide in solution, and a known liver toxicant classified as possibly carcinogenic to humans.

Thioacetone

Thioacetone, also known as propane-2-thione, is the simplest thioketone, the sulfur analog of acetone. It is unstable above −20 °C and infamous for a 1889 stench across Freiburg.

Thioaldehyde

A thioaldehyde is the sulfur analog of an aldehyde, R–CH=S; simple examples are so unstable that most are generated in situ for use in cycloaddition chemistry.

Thioanisole

Thioanisole (methyl phenyl sulfide) is an aryl sulfide, formula C₇H₈S, a colorless liquid with a strong unpleasant odor used as a flavoring and as a reagent and scavenger in peptide synthesis.

Thiobacillus

Thiobacillus is a genus of Gram-negative, rod-shaped sulfur-oxidizing bacteria in the Betaproteobacteria, established by Beijerinck in 1904; once covering over 30 species, it now holds three, with T. thioparus as type.

Thiobarbituric acid

Thiobarbituric acid (TBA) is a sulfur analog of barbituric acid, known as the reagent of the TBARS assay for lipid peroxidation and the parent of thiobarbiturate anesthetics.

Thiobencarb

Thiobencarb (benthiocarb; Saturn, Bolero) is a thiocarbamate, VLCFA-elongase-inhibiting pre-emergence herbicide developed by Kumiai Chemical Industry, launched 1969, used mainly on rice, with declining US use amid weed resistance and aquatic toxicity concerns.

Thiocarbamate

A thiocarbamate is an organic compound in which sulfur replaces oxygen in a carbamate, giving S- and O-linked families; the class includes herbicides, the Newman–Kwart rearrangement, and disulfiram-related drugs.

Thiocarbonate

A thiocarbonate is a salt or ester formally derived from carbonic acid in which one or more oxygens are replaced by sulfur, spanning mono-, di-, and trithiocarbonates.

Thiocarboxylic acid

A thiocarboxylic acid (thioacid) is a compound in which sulfur replaces one or both oxygens of a carboxy group, about 25 to 30 times more acidic than carboxylic acids.

Thiocolchicoside

Thiocolchicoside, a semi-synthetic colchicoside derivative from Gloriosa superba seeds, is a GABA-A/glycine receptor muscle relaxant for musculoskeletal pain; EMA restricted oral/IM use in 2013 over genotoxic metabolite M2, and meta-analysis shows marginal efficacy.

Thiocyanate

Thiocyanate (SCN−), pseudohalide anion of thiocyanic acid, first synthesized by Robert Porrett in 1809; forms metal complexes, ends cyanide detoxification via rhodanese, feeds antimicrobial hypothiocyanite, and inhibits thyroid iodide uptake.

Thiocyanic acid

Thiocyanic acid (HSCN, also called sulfocyanic acid) is the sulfur analog of cyanic acid and conjugate acid of thiocyanate, with a pKa of 1.1 and an equilibrium lying almost entirely in the isothiocyanic acid form.

Thiocyclam

Thiocyclam (Evisect, Dothian) is a nereistoxin-analogue organosulfur insecticide, IRAC Group 14 nAChR channel blocker, used as hydrogen oxalate against rice and vegetable pests; not EU-approved, toxic to bees and fish.

Thiodicarb

Thiodicarb (CAS 59669-26-0, Larvin) is a carbamate insecticide and molluscicide, a dimer of methomyl that inhibits acetylcholinesterase; WHO class II, EPA B2 probable carcinogen, not EU-approved.

Thioester

A thioester is an organic functional group in which a carbonyl carbon bonds to sulfur, the sulfur analog of an ester, less stable but highly effective at transferring acyl groups.

Thioester reactivity and synthesis

Thioester reactivity and synthesis covers the laboratory chemistry of acyl–sulfur compounds: their nucleophile-dependent reactivity, hydrolysis and thiol–thioester exchange, transition-metal cross-coupling, and methods for making thioesters from acids, alcohols, and halides.

Thioesterase

A thioesterase is a hydrolase enzyme that cleaves thioester bonds, splitting acyl-CoA into a free fatty acid and coenzyme A, thereby regulating fatty acid metabolism.

Thioesterase domain

Thioesterase domain: type I TE domain (240–290 aa, α/β hydrolase fold) at the C-terminus of PKS/NRPS modules that releases chains by hydrolysis or macrocyclisation; type II TEs are standalone editing enzymes; classified in TE16 and TE18 families.

Thioesterase type II, NRPS/PKS/S-FAS

Thioesterase type II, NRPS/PKS/S-FAS (InterPro IPR012223): standalone 25–29-kDa alpha/beta hydrolase enzymes that edit and repair PKS, NRPS, and fatty acid synthase carrier proteins, improving secondary metabolite yields.

Thioesters in natural products and materials

Thioesters in natural products and materials covers the reactive, exchangeable C(=O)–S linkage found in drug biosynthesis and in polythioesters, degradable sulfur analogs of polyesters not yet commercialized as of 2024.

Thiofanox

Thiofanox (Dacamox, DS 15647), CAS 39196-18-4, is a systemic oxime carbamate insecticide and acaricide, an acetylcholinesterase inhibitor (IRAC 1A), introduced circa 1973, now not approved in the EU and not registered in the US, with rat oral LD50 8.5 mg/kg.
