Pseudosaccharin amines were synthesized from saccharin either by the reaction of pseudosaccharin chloride with amines, or via thiosaccharin which was treated with amines yielding thiosaccharinates, and their reaction with glacial acetic acid. This route gave lower yields than the first way. The synthesis of alkyl [(1,1-dioxo-benzo[d]isothiazol-3-yl)amino]alkanoates as possible human leukocyte elastase (HLE) inhibitors was realized by the reaction between amino acid esters and pseudosaccharin chloride. Hydrolysis of the esters was possible under aqueous basic conditions. Selected compounds were screened for elastase inhibitory activity. Compounds (I) and (II) were found to be reversible inhibitors of HLE with K_i values of 45 μM and 60 μM.

Application In Synthesis of (1S,3R)-1,2,2-Trimethylcyclopentane-1,3-dicarboxylic acid. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: (1S,3R)-1,2,2-Trimethylcyclopentane-1,3-dicarboxylic acid, is researched, Molecular C10H16O4, CAS is 560-09-8, about Oriented Circular Dichroism Analysis of Chiral Surface-Anchored Metal-Organic Frameworks Grown by Liquid-Phase Epitaxy and upon Loading with Chiral Guest Compounds. Author is Gu, Zhi-Gang; Buerck, Jochen; Bihlmeier, Angela; Liu, Jinxuan; Shekhah, Osama; Weidler, Peter G.; Azucena, Carlos; Wang, Zhengbang; Heissler, Stefan; Gliemann, Hartmut; Klopper, Wim; Ulrich, Anne S.; Woell, Christof.

Oriented CD (OCD) is explored and successfully applied to study chiral surface-anchored metal-organic frameworks (SURMOFs) based on camphoric acid (D- and Lcam) [Cu2(Dcam)2x(Lcam)2-2x(dabco)]n (dabco = 1,4-diazabicyclo-[2.2.2]-octane). The three-dimensional chiral SURMOFs with high-quality orientation were grown on quartz glass plates by using a layer-by-layer LPE method. The growth orientation, as determined by XRD, could be switched between the [001] and [110] direction by using either OH- or COOH-terminated substrates. These SURMOFs were characterized by using OCD, which confirmed the ratio as well as the orientation of the enantiomeric linker mols. Theor. computations demonstrate that the OCD band intensities of the enantiopure [Cu2(Dcam)2(dabco)]n grown in different orientations are a direct result of the anisotropic nature of the chiral SURMOFs. Finally, the enantiopure [Cu2(Dcam)2(dabco)]n and [Cu2(Lcam)2(dabco)]n SURMOFs were loaded with the two chiral forms of Et lactate [(+)-ethyl-D-lactate and (-)-ethyl-L-lactate]. An enantioselective enrichment of >60% was observed by OCD when the chiral host scaffold was loaded from the racemic mixture

Antirhinovirus activity of 3-methylthio-5-aryl-4-isothiazolecarbonitrile derivatives

A series of 3-methylthio-5-aryl-4-isothiazolecarbonitriles has been evaluated as anti rhinovirus agents against a panel. of 17 representative human rhinovirus (HRV) serotypes, belonging to both A and B groups. No anti rhinovirus activity was detected for 3-methylthio-5-phenyl-4-isothiazolecarbonitrile (IS-2). Isothiazole derivatives with bulky substituents (O-Bn or O-But groups) on the para position of the phenyl ring were the most effective compounds of this series. In fact, a reduction in virus-induced cytopathogenicity was demonstrated for the O-Bn substituted IS-50 compound against the majority (88%) of the rhinoviruses tested, whereas the compound with an O-Ts group (IS-44) was found to be a specific inhibitor of group B serotypes, exhibiting the lowest IC50 against HRVs type 2, 85 and 89. Our studies on the mechanism of action of IS-44 demonstrated that it prevents the thermal inactivation of HRV 2 infectivity, probably due to a conformational shift in the viral capsid and a decrease in affinity for the cellular receptor, resulting in an inhibition of attachment of the virions.
