An article , which mentions category: thiazolidine, molecular formula is C3H7NO2S. The compound – 1,1-Dioxo-isothiazolidine played an important role in people’s production and life., category: thiazolidine

Water-soluble aliphatic disulfides are oxidatively cleaved by borate-buffered periodate at 23 deg C.The reaction conditions were selected because they are used for the oxidation of methionine in protein modification, and we wanted to test the reactivity of the disulfide linkage in various bifunctional molecules under these conditions.A colorimetric method was developed which uses 2,2′-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) to determine the concentrations of periodate.The gamma-substituted amine-disulfide 1b consumes 4 equiv of periodate at a rate which is accelerated 100-fold over that of 4,4′-dithiodibutanol (1c) and forms the cyclic sulfinamide 3 an sulfonamide 4.To account for the stoichiometry and acceleration, we have proposed intermediates in which a nucleophilic sulfur atom attacks an oxygen atom of periodate to give an anhydride or complex rather than invoking direct oxygen atom transfer.The gamma- and delta-hydroxy disulfides 1a and 1c consume 5 equiv of periodate and are oxidized to the sulfonic acids.The rate of DL-methionine (2a) oxidation in water is reported, along with the oxidations of dibutyl sulfide (2c) and of 1,5-dithiacyclooctane (2d) in 50percent aqueous ethanol.The oxidation of 2d is only 2.1 times faster than the oxidation of 2c, showing that the transannular sulfur atom in 2d does not participate in the oxidation.A comparison of the rate of periodate oxidation of disulfides, thioethers, and ethylene glycol under the same conditions shows that it is possible for these processes to be competitive.

A novel series of (E)-1-((2-(1-methyl-1H-imidazol-5-yl) quinolin-4-yl) methylene) thiosemicarbazides was discovered as potent inhibitors of IKKbeta. In this Letter we document our early efforts at optimization of the quinoline core, the imidazole and the semithiocarbazone moiety. Most potency gains came from substitution around the 6- and 7-positions of the quinoline ring. Replacement of the semithiocarbazone with a semicarbazone decreased potency but led to some measurable exposure.

In a document type is Review, and a compound is mentioned, 2682-49-7, Thiazolidin-2-one, introducing its new discovery.

Background: The American trypanosomiasis, Chagas disease, is a parasitic infection typically spread by triatomine vectors affecting millions of people all over Latin America. Existing chemotherapy is centered on the nitroaromatic compounds benznidazole and nifurtimox that provide unsatisfactory results and substantial side effects. So, the finding and exploration of novel ways to challenge this neglected disease is a main priority. Methods: The biologic and biochemical progress in the scientific knowledge of Trypanosoma cruzi in the period comprising last 15-years has increased the identification of multiple targets for Chagas? disease chemotherapy. In the middle of the best encouraging targets for trypanocidal drugs, ergosterol biosynthesis pathway and cruzipain, a key cysteine protease (CP) of T. cruzi, have been pointed out. Unfortunately, recent clinical trials investigating the administration of pozoconazole and ravuconazole to chronic indeterminate Chagas disease patients revealed their inferiority compared to the standard drug Benznidazole. Results: In view of the information gained in the preceding years, a reasonable approach for the fast development of novel anti-T. cruzi chemotherapy would be focused on K777, the cysteine proteinase inhibitor (CPI) near to enter to clinical trials, and founded on the clinical evaluation of combination of known drugs with existing trypanocidal agents to obtain more efficiency and less secondary effects. Top series of xanthine have been recently identified as clinical candidate for Chagas disease. In addition, trypanothione biosynthesis, thiol-dependant redox and polyamine metabolism, the glycolytic, glyconeogenic, pentose phosphate, lipidic and polyisoprenoid biosynthetic pathways, and the enzymes from biosynthetic glycoconjugates pathways have been studied. Several specific enzymes from these particular biosynthetic pathways such as hypoxanthine-guaninephosphoribosyl-transferase and farnesyl-pyrophosphate synthase, among others, have also been broadly studied in T. cruzi. Novel synthesized anti-T. cruzi compounds with or without specific single or multi-target assigned are also described in detail. Conclusion: In summary, loans on anti-Chagas disease agents focused to specific parasite targets as their metabolic pathways or specific enzymes will be summarized. Targets will also be specifically discussed. Patent literature collected and published from 2000 to 2015, alleging inhibitors for specific T. cruzi targets or trypanocidal activity was achieved over the search database from Delphion Research intellectual property network including international patents and the European patent office, Espacenet.

N-Mannich bases are an important structure in various functional molecules. A new protocol to synthesize N-Mannich bases was established through electrochemical external-oxidant-free C(sp3)?H/N?H cross-coupling with hydrogen evolution. Various N-methylanilines were explored in this transformation. Moreover, simple amides, heteroatom-containing amides, and succinimides were well tolerated in moderate-to-good yields. In addition, the electrochemical dehydrogenative C(sp3)?H/N?H cross-coupling could be scaled up to 5 mmol. By using triethyl phosphite as trapping agent, the phosphorylation product was detected. At the same time, kinetic isotope effect experiments showed that the cleavage of the C?H bond is the rate-limiting step.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.category: thiazolidine, you can also check out more blogs about2682-49-7
