Research Progress on the Antitumor Molecular Mechanism of Ginsenoside Rh2

The American Journal of Chinese Medicine
Cancer has evolved into a substantial public health concern as the second-leading cause of mortality globally. Radiotherapy and chemotherapy have been the two most widely used cancer therapies in recent years; however, both have drawbacks. Therefore, the focus has shifted to the creation of herbal medicines, the extraction of active ingredients ...

Theoretical studies of the interaction of butadiene with Rh and Rh2

Chemical Physics Letters, 1998
Abstract Butadiene–Rh and –Rh 2 complexes have been studied using the density functional (DFT) and Moller–Plesset (MP2 and MP4) calculations. For the butadiene–Rh complex complete active space multiconfiguration self-consistent field method (CASMCSCF) followed by multireference singles and doubles (MRSDCI) calculations were employed.

Interligand interactions affecting specific metal bonding to nucleic acid bases. A case of [Rh2(OAc)4], [Rh2(HNOCCF3)4], and [Rh2(OAc)2(HNOCCF3)2] toward purine nucleobases and nucleosides

Inorganica Chimica Acta, 2002
Abstract The reaction of [Rh2(OAc)4] with adenine, 9-methyladenine, 9-ethylguanine, adenosine, guanosine, deoxyguanosine, or inosine in methanolic aqueous solution at room temperature gave specifically and quantitatively pink complexes of adenine or its derivatives (=L), [Rh2(OAc)4(L)] (the dirhodium-core:L ratio of 1:1). The reaction of [Rh2(HNOCCF3)

Rhodium(II) Acetate Donor–Acceptor Complexes Rh2(OAc)4(Diox)2, Rh2(OAc)4(Dmso)2, and Rh2(OAc)4[(4-FC6H4)3Sb]2: Synthesis and Structure

Russian Journal of Inorganic Chemistry, 2019
The rhodium diacetate complexes with dioxane Rh2(OAc)4(Diox)2 (I) and dimethyl sulfoxide Rh2(OAc)4(Dmso)2 (II) have been synthesized by dissolving rhodium diacetate [Rh2(OAc)4] in dioxane (Diox) and dimethyl sulfoxide (Dmso) with the further slow evaporation of the solvent.

Optical spectroscopy of Cr3+ and Rh2+ in sodium-betaalumina

Journal of Luminescence, 1987
Abstract Ion exchange techniques were used to substitute Cr 3+ and Rh 2+ ions for the sodium ions present in sodium-beta″-alumina single crystals. The optical absorption and fluorescence spectra were obtained and the fluorescence lifetimes measured for both types of samples.

[Effects of ginsenoside Rh2(GS-Rh2) on cell cycle of Eca-109 esophageal carcinoma cell line].

Zhongguo Zhong yao za zhi = Zhongguo zhongyao zazhi = China journal of Chinese materia medica, 2007
To investigate the effects of ginsenoside Rh2 (GS-Rh2) on growth inhibition and cell cycle of Eca-109 esophageal carcinoma cell line in culture.The effects of GS-Rh2 on cell growth inhibition was detected by MTT assay. Cell cycle was analyzed by flow cytometry (FCM). Cell morphology was observed by a light microscope after HE staining.

Specific heat of (Cel-cGdc)Rh2 compounds

Journal of Alloys and Compounds, 1992
Abstract The series (Ce1-cGdc)Rh2 has been investigated by means of specific heat measurements. At the CeRh2 end of the series the substitution of gadolinium for cerium reduces the τ value. At c=0.12 the system enters into a spin-glass-like magnetic phase.

Therapeutic Effects of Ginsenoside Rh2 in the Treatment of Sepsis

Journal of Biobased Materials and Bioenergy
Panax ginseng, a well-known traditional Chinese medicine (TCM) with a wide range of pharmacological activities, has been extensively investigated. However, its specific pharmacological mechanism in preventing and treating sepsis remains elusive.
