In the present work, nanocrystalline disodium 6-hydroxy-5-[(2-methoxy-5-methyl-4-sulfophenyl) azo]-2-naphthalenesulfonate (AR) thin films based devices were prepared by using electro-spin technique under best conditions. The nanostructure characteristics of the AR surfaces were found to be nanos...

5,10,15,20-Tetra(4-nitrophenyl) porphyrinato gallium chloride (ClGaTNPP) and 5,10,15,20-tetra(4-sulfophenyl) porphyrinato gallium chloride (ClGaTSPP) and their metal free derivatives were successfully synthesised and were added to Pluronic F127 polymeric micelles to form ClGaTNPP-F127 (or H2TNPP...

We have developed novel formazan dyes (18–23) of enhanced fastness properties with cost-effectiveness in an aqueous system, without employing any Buffers and organic solvents. Their development was entailed of the synthesis of 2-((phenyl (2-(4-sulfophenyl) hydrazono) methyl) diazenyl) benzoic a...

A series of isomeric bis(chlorophthalimide)s (BCPIs) were conveniently prepared from 3-chlorophthalic anhydride, 4-chlorophthalic anhydride, and mixtures thereof. Polymerization of BCPIs with bis(4-mercaptophenyl) sulfone (BMPS) proceeded smoothly in the presence of tributylamine, from which a c...

Two novel bis(amine anhydride) monomers, N,N′-bis(3,4-dicarboxyphenyl)-1,4-phenylenediamine dianhydride I and N,N′-bis(3,4-dicarboxyphenyl)-1,3-phenylenediamine dianhydride II, were prepared via palladium-catalyzed amination reaction of 4-chloro-N-methylphthalimide with 1,4-phenylenediamine or...

Gallic acid (I) has been isolated as a specific flowering-inhibitory substance from leaves of vegetative Kalanchoe blossfeldiana. It is also present in leaves of flowering Kalanchoe, apparently in an inactive, non-dialysable form. Gallic acid acts as a flowering inhibitor when applied to Kalanch...

We determined the effects of emulsifier concentration and temperature on the distribution of gallic acid (GA) in a food-grade emulsion composed of 1:9 vol:vol stripped corn oil, acidic water and Tween 20. The distribution of GA can be defined by the partition constant between the aqueous and the...

Novel biobased epoxy thermoset was synthesized from gallic acid, a phenolic acid encountered in various plants, both in its simple form and as a part of gallotannins. The functionalization of gallic acid was carried out using a two-step synthesis involving the allylation of OH groups followed by...

Embryogenic callus was induced from leaf explants of Eleutherococcus sessiliflorus cultured on Murashige and Skoog (MS) basal medium supplemented with 1 mg l−1 2,4-dichlorophenoxyacetic acid (2,4-D), while no plant growth regulators were needed for embryo maturation. The addition of 1 mg l−1 2,4...

The effect of initial sucrose concentration was investigated in embryogenic cell cultures of Eleutherococcus sessiliflorus in bioreactors for production of eleutherosides, phenol, flavonoids and polysaccharide. The final dry cell weight was increased from 6.16 to 23.33 g l−1 with an increase of ...

Eleutherococcus koreanum (E. koreanum) is an endangered medicinal plant, which has been used for the treatments of rheumatism, diabetes and hepatitis. An in vitro methodology has been developed for mass propagation of E. koreanum by using adventitious root explants in liquid cultures. Among the ...

Eleutheroside E (EE), a principal component of Eleutherococcus senticosus, has been reported to have anti-inflammatory and protective effects in ischemia heart etc. However, whether it can mitigate behavioral alterations induced by sleep deprivation, has not yet been elucidated. Numerous studies...

The effects of methyl jasmonate elicitation were investigated in embryogenic suspension cultures of Eleutherococcus sessiliflorus in bioreactors for the production of eleutherosides and chlorogenic acid. Eleutherosides and chlorogenic acid increased with methyl jasmonate elicitation (in the rang...

A HPLC method with photodiode array detection (PDA) was developed for the determination and a pharmacokinetic study of eleutheroside E (ELU E) and eleutheroside B (ELU B) in rat plasma and tissue following an eleutherococcus injection. The analysis was performed on a Kromasil C18 column, using w...

We report herein the synthesis of a series of fifteen 2-hydroxyisoquinoline-1,3(2H,4H)-dione derivatives. Alkyl and arylalkyl groups were introduced on position 4 of the basis scaffold.
