Abstract:

Abstract The potential inhibitory effect of diverse triazolyl-ferrocene steroids on key enzymes of the estrogen biosynthesis was investigated. Test compounds were synthesized via copper-catalyzed cycloaddition of steroidal azides and ferrocenyl-alkynes using our efficient methodology published previously. Inhibition of human aromatase, steroid sulfatase (STS) and 17β-hydroxysteroid dehydrogenase type 1 (17β-HSD1) activities was investigated with in vitro radiosubstrate incubations. Some of the test compounds were found to be potent inhibitors of the STS. A compound bearing ferrocenyl side chai

Abstract:

Starting from ethyl 2,4-dioxo-4-ferrocenyl-butanoate (1) a series of new ferrocene derivatives has been prepared. While the reaction with o-phenylene diamine leads to two ferrocene-containing heterocyclic compounds, 4-ferrocenyl-3H-1,5-benzodiazepine-2-carbonic acid ethyl ester (3) and 3-(2-ferrocenyl-2-oxo-ethylidene)-3,4-dihydro-1H-quinoxalin-2-one · H20 (4), reactions with m- and p-phenylene diamine give both the mono- and disubstituted products 5 - 8, respectively. The conversion of 4 by Lawesson’s reagent results in 2-ferrocenvl-thieno[2,3- b]quinoxaline (9). The new compounds have been c

Abstract:

Abstract Ferrocene and its derivatives constitute versatile and interesting scaffolds for the global chemical enterprise due to its multiple applications that range from biomedical to materials science. Ferrocenyl derivatives are the leading compounds in our research for the syntheses and characterization as well as their potential biological applications. Among them, our recent focus has been in ferrocenyl chalcones as a framework for further derivatization. The proposed modifications consist on the incorporation of heterocyclic moieties into the ferrocenyl chalcone core. This can be afforded

Abstract:

The title compound [(N,N-dimethylamino)methyl]ferrocene, [Fe(C5H5)(C8H12N)], (1), is an interesting starting material for the synthesis of planar chiral 1,2-disubstituted ferrocenes, as demonstrated by the preparation of (R p,R p)-bis{2-[(dimethylamino)methyl]ferrocenyl}dimethylsilane, [Fe2(C5H5)2(C18H18N2Si)], (2), from the lithiated derivative of 1. The configuration of the lithium compound is unchanged after the substitution reaction and the chirality is preserved in space group P212121. In both compounds, the Cp rings adopt eclipsed conformations. Hirshfeld surface analysis was used to inv

Abstract:

The derivatives of 3-ferrocenyl isocoumarin were synthesized by the condensation of substituted homothphalic anhydride with ferrocene using phosphoric acid or anhydrous aluminium chloride as cyclising agent. Substituted homophthalic acid did not condense with ferrocene so homophthalic acids were converted into their anhydride and then allowed to react with ferrocene in the presence of polyphosphoric acid or in the presence of anhydrous aluminium chloride using dichloromethane as the solvent to give 3-ferrocenyl isocoumarins. 7-Methoxy, 6-methyl, 5,7-dihydroxy, 6,7-dimethoxy and 5,7-dimethoxy d

Abstract:

Alkyl-substituted acetylenes and diacetylenes with terminal ferrocenyl groups were synthesised starting from ferrocene. The reactivity of the triple bonds in the resulting compounds was used to prepare cobalt-alkyne complexes. Cyclotrimerisation of the monoacetylene resulted in a hexa-substituted benzene derivative with six pending ferrocenyl groups.

Abstract:

AbstractThe goal of this paper is to study thermal stability of some ferrocenes with acidic functional groups. Some other kinetic characteristics such as critical temperature and the rate constant corresponding to maximal degradation speed have been also evaluated. The type of functional units adjacent to the ferrocenyl unit determines thermal stability of ferrocene compounds. Groups with a powerful withdrawing effect determine a decreasing of the temperatures at which the material starts to lose weight. If a very long alkyl chain is connected to the ferrocene unit, a shielding effect in respe

Abstract:

Background: Due to the astonishing properties of ferrocene and its derivatives, it has a broad application in diverse areas. Numerous ferrocene derivatives demonstrated anti-proliferative activity. Also COX-2, as a key isoenzyme for production of prostaglandins, is frequently overexpressed in various cancers. It is now recognized that COX-2 over expression promotes tumorigenic functions which can be suppressed by COX-2 inhibitors, a phenomenon useful for the preventing of tumor progression. The combination of COX-2 inhibitors with other anti-cancer or cancer prevention drugs may reduce their s
