Zygophyllaceae
An in vitro evaluation of human DNA topoisomerase I inhibition by Peganum harmala L. seeds extract and its beta-carboline alkaloids. (1/6)
PURPOSE: Peganum harmala L. (Zygophyllaceae) seeds extract is one of the main components of an ethnobotanical preparation used in the treatment of neoplasms in Iran. Cytotoxic effects of P. harmala extract on cancerous cell-lines have been reported before. beta-carbolines like harmaline and harmine are the major alkaloids present in the seeds of the P. harmala. Considering reports concerning DNA topoisomerase inhibition by other beta-carbolines like harmane, we have used DNA relaxation assays to investigate topoisomerase I inhibitory activity of P. harmala seeds extract and its beta-carboline alkaloids to further inspecting the mechanism of its cytotoxic activity. METHODS: Harmine and harmaline contents of the extract were determined using an HPTLC method. DNA topoisomerase I enzyme needed for investigating inhibitory effect of the compounds using DNA relaxation assay, was partially purified from the human placenta. DNA relaxation assay is based on the conversion of a supercoiled plasmid substrate to its relaxed form by the catalytic activity of the enzyme. The supercoiled substrate and its relaxed product can be easily distinguished using agarose gel electrophoresis, since the relaxed topological isomers of DNA migrate more slowly than supercoiled species. RESULTS: Using HPTLC method, it was found that each gram of dried extract contained 55.5 and 79.0 mg of harmine and harmaline respectively. In the DNA relaxation assay, order of potency was harmine > harmane > harmaline > extract. The most active compound was harmine with IC50 value of 13.5 +/- 1.7 microg/ml. CONCLUSIONS: Our in vitro findings demonstrate that P. harmala seeds extract do inhibit human DNA topoisomerase I and based on the results of HPTLC analysis, it appears that the biological activity of the extract can be explained by its beta-carboline content.

(2/6)
BACKGROUND: The major damaging factor during and after the ischemic/hypoxic insult is the generation of free radicals, which leads to apoptosis, necrosis and ultimately cell death. Rubia cordifolia (RC), Fagonia cretica linn (FC) and Tinospora cordifolia (TC) have been reported to contain a wide variety of antioxidants and have been in use in the eastern system of medicine for various disorders. However, their mechanism of action was largely unknown. We therefore selected these herbs for the present study to test their neuroprotective ability and the associated mechanism in rat hippocampal slices subjected to oxygen-glucose deprivation (OGD). METHODS: Hippocampal Slices were subjected to OGD (oxygen glucose deprivation) and divided into 3 groups: control, OGD and OGD + drug treated. Cytosolic Cu-Zn superoxide dismutase (Cu-Zn SOD), reduced glutathione (GSH), glutathione peroxidase (GPx), nitric oxide (NO) was measured as nitrite (NO2) in the supernatant and protein assays were performed in the respective groups at various time intervals. EPR was used to establish the antioxidant effect of RC, FC and TC with respect to superoxide anion (O2.-), hydroxyl radicals (. OH), nitric oxide (NO) radical and peroxynitrite anion (ONOO) generated from pyrogallol, menadione, DETA-NO and Sin-1 respectively. RT-PCR was performed for the three groups for GCLC, iNOS, Cu-Zn SOD and GAPDH gene expression. RESULTS: All the three herbs were effective in elevating the GSH levels, expression of the gamma-glutamylcysteine ligase and Cu-Zn SOD genes. The herbs also exhibited strong free radical scavenging properties against reactive oxygen and nitrogen species as studied by electron paramagnetic resonance spectroscopy. In addition all the three herbs significantly diminished the expression of iNOS gene after 48 hours which plays a major role in neuronal injury during hypoxia/ischemia. CONCLUSIONS: RC, FC and TC therefore attenuate oxidative stress mediated cell injury during OGD and exert the above effects at both the cytosolic as well as at gene expression level and may be an effective therapeutic tool against ischemic brain damage.

In gynodioecious populations, the frequency of females is expected to have a strong influence on the contemporary genetic structure of populations. Historical patterns of range contraction and expansion are also known to influence the genetic diversity of plant populations. We explore the influence of male sterility and colonization history on the genetic diversity in populations of Kallstroemia grandiflora along the Pacific of Mexico. Both the overall population Fis and Fis values of hermaphrodites showed a negative association with female frequency. Genetic diversity declined with latitude. Our results provide evidence that females have a significant effect on the genetic structure as predicted by theoretical models and provide support for the hypothesis that historical processes have modified the genetic structure of K. grandiflora. (+info)Effect of Fagonia Arabica (Dhamasa) on in vitro thrombolysis. (4/6)
BACKGROUND: Atherothrombotic diseases such as myocardial or cerebral infarction are serious consequences of the thrombus formed in blood vessels. Thrombolytic agents are used to dissolve the already formed clots in the blood vessels; however, these drugs have certain limitations which cause serious and sometimes fatal consequences. Herbal preparations have been used since ancient times for the treatment of several diseases. Herbs and their components possessing antithrombotic activity have been reported before; however, herbs that could be used for thrombolysis has not been reported so far. This study's aim was to investigate whether herbal preparations (aqueous extract) possess thrombolytic activity or not. METHODS: An in vitro thrombolytic model was used to check the clot lysis effect of six aqueous herbal extracts viz., Tinospora cordifolia, Rubia cordifolia, Hemidesmus indicus, Glycyrrhiza glabra Linn, Fagonia Arabica and Bacopa monnieri Linn along with Streptokinase as a positive control and water as a negative control. RESULTS: Using an in vitro thrombolytic model, Tinospora cordifolia, Rubia cordifolia, Hemidesmus indicus, Glycyrrhiza glabra Linn, Fagonia Arabica and Bacopa monnieri Linn showed 19.3%, 14.5%, 20.3%, 17.8%, 75.6% and 41.8% clot lysis respectively . Among the herbs studied Fagonia arabica showed significant % of clot lysis (75.6%) with reference to Streptokinase (86.2%). CONCLUSION: Through our study it was found that Dhamasa possesses thrombolytic properties that could lyse blood clots in vitro; however, in vivo clot dissolving properties and active component(s) of Dhamasa for clot lysis are yet to be discovered. Once found Dhamasa could be incorporated as a thrombolytic agent for the improvement of patients suffering from Atherothrombotic diseases.

(+info)Zygophyllaceae is not a medical term, but a taxonomic category in botany. It refers to the family name of a group of flowering plants commonly known as "caltrop family" or "creosote bush family." The plants in this family are primarily found in arid and semi-arid regions worldwide.
Some members of Zygophyllaceae have been used in traditional medicine, but it is essential to note that the use of any plant for medicinal purposes should be done under the guidance of a qualified healthcare professional, as not all plants are safe or effective for treating medical conditions.
Guaiacum is not a medical term itself, but it refers to two species of small trees native to the Caribbean: Guaiacum officinale and Guaiacum sanctum. The wood of these trees has been used in traditional medicine for its anti-inflammatory and expectorant properties. It contains a compound called guaiacol, which is believed to have medicinal benefits. However, there is limited scientific evidence supporting its effectiveness, and its use as a medical treatment is not widely accepted or recommended in modern medicine.
