Surface-induced dimerization of 2-thiazoline-2-thiol on silver and gold nanoparticles: A surface enhanced Raman scattering (SERS) and density functional theoretical (DFT) study

, 2020
The adsorption behavior of an anti-thyroid agent, 2-thiazoline-2-thiol (TT) on silver (Ag) and gold (Au) nanoparticles (NPs) was studied using surface enhanced Raman scattering (SERS) and density functional theory (DFT).

D3-Thiazolines, D4-Thiazolines and Thiazoles from Penem Antibiotics

HETEROCYCLES, 1992
Upon cleavage of the β-lactam ring, penems are converted to unstable Δ 4 -thiazolines, which epimerize at the ex-C-5 position, lose a nucleofugal group at C-2' (if originally present), tautomerize to Δ 3 -thiazolines, or suffer hydrolytic decomposition.

Thiazoline carboxylic acid from formylcysteine

Experientia, 1957
La formilcisteina in HCl 12N da un assorbimento nell'ultravioletto indicante la formazione di un anello tiazolinico. La reazione e piu rapida per la formilcisteina che per il glutatione e dipende dalla concentrazione dell'acido. Trattando la formicilsteina con HCl 12N, e stato preparato un composto avente le proprieta dell'acido tiazolin carbossilico ...

Infrarotspektren einiger Thiazoline

Chemische Berichte, 1955
AbstractDie Infrarotspektren von 15 in 2‐Stellung substituierten Thiazolinen wurden aufgenommen. Folgende charakteristische Frequenzen treten auf: a) 6.1–6.45 μ (stark), b) 8.0–8.4 μ (mittelstark bis schwach) und c) 9.8–10.5 μ (stark). Thiazole absorbieren im Bereich a) (6.1–6.45 μ) nur schwach, Thiazolidine nicht.

Thiazoline-pyrene selective and sensitive fluorescence "turn-on" sensor for detection of Cu2.

Spectrochimica Acta Part A - Molecular and Biomolecular Spectroscopy, 2019
A thiazoline and pyrene containing sensor 1 was synthesized via one-pot reaction and utilized as a highly selective and sensitive fluorescence "turn-on" sensor for Cu2+ detection, via the fluorescence enhancement of pyrene monomer emission.

Tautomeric Modification of GlcNAc-Thiazoline

Organic Letters, 2007
The potent O-GlcNAcase (OGA) inhibitor GlcNAc-thiazoline has been modified by buffer- or acylation-induced imine-to-enamine conversion and then electrophile or radical addition (Xn = D3, F, N3, OH, SMe, COCF3, CF3). Several functionalized GlcNAc-thiazolines show highly selective inhibition of OGA vs human hexosaminidase and thus have promise as tools ...

Synthesis and antioxidant activity of pyrazolyl-oxazolines/thiazolines and isoxazolyl-oxazolines/thiazolines

Medicinal Chemistry Research, 2013
A new class of pyrazolyl/isoxazolyl-oxazolines and thiazolines were synthesized from E-arylsulfonylethenesulfonylacetic acid methyl ester and tested for antioxidant activity. Among the tested compounds, 14b exhibited excellent antioxidant activity when compared with the standard ascorbic acid.
