Abstract:

In this paper, a fluorescent probe based on a rhodamine spirolactam ring was designed and synthesized. Rhodamine derivatives not only have excellent chemical and optical-physical properties, but also the "OFF-ON" characteristic of the rhodamine spiroamide ring allows specific recognition and response to metal ions. In this paper, Rh-DCP, a rhodamine B derivative with a spirolactam ring, was synthesized by the Schiff base reaction and the effects of pH, time and temperature on this probe were tested.

Abstract:

Abstract At present, the research on fluorescent molecular probe has become a hot topic in the field of environmental science, chemical materials, medicine, and other fields. Therefore, the detection of industrial mercury-containing wastewater (Hg2+) is of great significance. In this article, the fluorescent probe is used to detect mercury ions, and when compared with the traditional detection method, the fluorescent probe has the advantage of operation such as the effect of simplicity is evident.

Abstract:

Pentacyclic triterpenoic acids (betulinic, oleanolic, ursolic, and platanic acid) were selected and subjected to acetylation followed by the formation of amides derived from either piperazine or homopiperazine. These amides were coupled with either rhodamine B or rhodamine 101. All of these compounds were screened for their cytotoxic activity in SRB assays. As a result, the cytotoxicity of the parent acids was low but increased slightly upon their acetylation while a significant increase in cytotoxicity was observed for piperazinyl and homopiperazinyl amides. A tremendous improvement in cytoto

Abstract:

Cyclodextrins are widely used excipients for increasing water-solubility, delivery and bioavailability of lipophilic drugs. By using fluorescent cyclodextrin derivatives, we showed previously that cyclodextrins are able to enter Caco-2 intestinal cells by endocytosis, but the influence of different fluorescent labeling on the same cyclodextrin derivative has not been studied. The consequences of the cellular internalization of cyclodextrins have not been revealed yet either. The aims of this study were to compare the cellular internalization of fluorescein- and rhodamine-labeled (2-hydroxyprop

Abstract:

Acid hydrolysis of stevioside resulted in a 63% yield of isosteviol (1), which served as a starting material for the preparation of numerous amides. These compounds were tested for cytotoxic activity, employing a panel of human tumor cell lines, and almost all amides were found to be non-cytotoxic. Only the combination of isosteviol, a (homo)-piperazinyl spacer and rhodamine B or rhodamine 101 unit proved to be particularly suitable. These spacered rhodamine conjugates exhibited cytotoxic activity in the sub-micromolar concentration range. In this regard, the homopiperazinyl-spacered derivativ

Abstract:

Various conjugates with rhodamines were prepared by starting with betulinic acid (BA) and platanic acid (PA). The molecules homopiperazine and piperazine, which were identified in earlier research, served as linkers between the rhodamine and the triterpene. The pentacyclic triterpene’s ring A was modified with two acetyloxy groups in order to possibly boost its cytotoxic activity. The SRB assays’ cytotoxicity data showed that conjugates 13–22, derived from betulinic acid, had a significantly higher cytotoxicity. Of these hybrids, derivatives 19 (containing rhodamine B) and 22 (containing rhoda

Abstract:

Plasmonic nanoparticles and low-dimensional graphene-based derivatives are increasingly used for decolourization and degradation of harmful organic pollutants. However, the utility of their hybrid compositions synthesized via low-cost routes is rarely discussed. Our research examines the efficiency of surfactant-free nanomaterials and their composites with graphene oxide towards the degradation of four important textile and laser dyes, namely: Rhodamine B (RB), Methylene blue (MB), Sulforhodamine 101 hydrate (SR) and Fluorescein (FS). The surfactant-free metal-graphene oxide nanocomposites are

Abstract:

A capillary electrophoresis microchip system with a confocal LIF detector was successfully constructed. RBPhOH, a new fluorescence dye synthesized from rhodamine B, was first investigated in a glass microchip for the selective and sensitive determination of copper ion by LIF method. The influences of the pH value, concentration of running buffer, detection voltage, and sample loading time on the response of LIF detector were studied. RBPhOH dissolved in 20 mM pH 6.0 Tris containing 10% acetonitrile could detect copper ions with a detection limit of 1.34×10−7 mol L−1 (S/N=3), an order of magnit
