Taurine (2-aminoethanesulfonic acid) is a representative substructure in biologically active compounds, but can raise difficulties in direct coupling reactions. In this study, the synthesis of taurine-derived sulfonic acids and analogous aromatic sulfonic
Highly Ligand Efficient and Selective N-2-(Thioethyl)picolinamide Histone Deacetylase Inhibitors Inspired by the Natural Product PsammaplinA

Novel picolinamide-based histone deacetylase (HDAC) inhibitors were developed, drawing inspiration from the natural product psammaplinA. We found that the HDAC potency and isoform selectivity provided by the oxime unit of psammaplinA could be reproduced b

β-Hydroxy amides 6 and 7 were treated with triphenylphosphonium anhydride trifluoromethane sulfonate (3), or the cyclic analogue 4, to generate 2-oxazolines 5 and 8 under mild conditions. The reaction was optimised by examining the number of equivalents of reagents 3 or 4, or diisopropylethyl amine required to best effect cyclisation. The effects of altering the reaction temperature, reaction time, concentration, solvent, and addition rate also were investigated. However, it was found that use of a trityl group to block reaction at the hydroxyl or thiol group of the starting amides, and subsequent in situ detritylation, in the absence of base, led to greatly improved yields. Reagent 4 offered significant advantages in the purification of products and was used to dehydrate a range of trityl derivatives to form simple oxazolines, thiazolines, and a dihydro-1,3-oxazine, in high yield (85-99%), as well as a tetrahydro-1,3-oxazepine (31%).
Discovery of new small molecules that influence neuroblast cell migration from the subventricular zone

Using SVZ (subventricular zone) tissue explants from one-day-old mice, we investigated the activity of new amino aromatic disulfide analogues and polyazamacrocycles on the migration of SVZ cells (neuroblasts). We found that among the tested analogues, non
Zeolite-catalyzed simple synthesis of different heterocyclic rings, part 2
Hegedues, Adrienn,Vigh, Ilona,Hell, Zoltan
, p. 428 - 431 (2007/10/03)
A simple and environmentally friendly synthesis was developed for the preparation of 2-arylimidazoline derivatives and 2-arylbenzoxazole derivatives using a small pore size zeolite. The similar reaction was not applicable to the preparation of the sulfur-containing analogs cysteamine or 2-aminothiophenol, probably because of a disadvantageous reaction between the zeolite and the thio compound.
Direct Disulfide Formation from 2-Quinolinylmethyl Thioethers with Iron(III) or Copper(II) Salt
Yoshizawa, Hidenori,Otaka, Akira,Habashita, Hiromu,Fujii, Nobutaka
, p. 803 - 806 (2007/10/02)
2-Quinolinylmethyl thioethers were efficiently cleaved to generate the corresponding symmetrical disulfides using the following systems; FeCl3/N,N-dimethylformamide (DMF)/H2O, FeCl3/ethanol (EtOH)/H2O, and CuCl2/DMF/H2O.The 2-quinolinylmethyl group was utilized as a thiol protecting group in the synthesis of a model peptide.

It has been found that bis(2-benzylaminoethyl)-disulfides with the phenyl rings carrying various simple substituents, are highly effective anti-inflammatories and inhibit chemotaxis of human neutrophils.
