1,3-Dithiole
In organosulfur chemistry, 1,3-dithioles are a class of heterocycles based on the parent compound 1,3-dithiacyclopentene (also known as 1,3-dithiole). The ligand dmit2- is a 1,3-dithiole. Heating solutions of Na2dmit gives the isomeric In chemistry, isomers are molecules or polyatomic ions with identical molecular formulae – that is, same number of atoms of each element – but distinct arrangements of atoms in space. Isomerism is existence or possibility of isomers. Iso ... disulfide, a 1,2-dithiole. References {{DEFAULTSORT:Dithiole, 1,2- Dithioles ...

1,2-Dithiole
In organosulfur chemistry, a 1,2-dithiole is a type of heterocycle. The parent of this class of compounds is 1,2-dithiacyclopentene. The anticancer drug oltipraz Oltipraz is an organosulfur compound belonging to the dithiolethione class. It acts as a schistosomicide and has been shown in rodent models to inhibit the formation of cancers in the bladder, blood, colon, kidney, liver, lung, pancreas, stomac ... is a dithiole. : See also * Dithiolium salt References {{DEFAULTSORT:Dithiole, 1,2- Dithioles ...

Heterocycle
A heterocyclic compound or ring structure is a cyclic compound that has atoms of at least two different chemical element, elements as members of its ring(s). Heterocyclic chemistry is the branch of organic chemistry dealing with the synthesis, properties, and applications of these heterocycles. Examples of heterocyclic compounds include all of the nucleic acids, the majority of drugs, most biomass (cellulose and related materials), and many natural and synthetic dyes. More than half of known compounds are heterocycles. 59% of US FDA-approved drugs contain nitrogen heterocycles. Classification The study of heterocyclic chemistry focuses especially on unsaturated derivatives, and the preponderance of work and applications involves unstrained 5- and 6-membered rings. Included are pyridine, thiophene, pyrrole, and furan. Another large class of heterocycles refers to those fused to benzene rings. For example, the fused benzene derivatives of pyridine, thiophene, pyrrole, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
