Investigating Therapeutic Potential of Trigonella foenum-graecum L. as Our Defense Mechanism against Several Human Diseases.

Abstract: Current lifestyle, stress, and pollution have dramatically enhanced the progression of several diseases in human. Globally, scientists are looking for therapeutic agents that can either cure or delay the onset of diseases. Medicinal plants from time immemorial have been used frequently in therapeutics. Of many such plants, fenugreek is one of the oldest herbs which have been identified as an important medicinal plant by the researchers around the world. It is potentially beneficial in a number of diseases such as diabetes, hypercholesterolemia, and inflammation and probably in several kinds of cancers. It has industrial applications such as synthesis of steroidal hormones. Its medicinal properties and their role in clinical domain can be attributed to its chemical constituents. The 3 major chemical constituents which have been identified as responsible for principle health effects are galactomannan, 4-OH isoleucine, and steroidal saponin. Numerous experiments have been carried out in vivo and in vitro for beneficial effects of both the crude chemical and of its active constituent. Due to its role in health care, the functional food industry has referred to it as a potential nutraceutical. This paper is about various medicinal benefits of fenugreek and its potential application as therapeutic agent against several diseases.

Diminution of oxalate induced renal tubular epithelial cell injury and inhibition of calcium oxalate crystallization in vitro by aqueous extract of Tribulus terrestris.

Abstract: PURPOSE: Recurrence and persistent side effects of present day treatment for urolithiasis restrict their use, so an alternate solution, using phytotherapy is being sought. The present study attempted to evaluate the antilithiatic properties of Tribulus terrestris commonly called as “gokhru” which is often used in ayurveda to treat various urinary diseases including urolithiasis. MATERIALS AND METHODS: The activity of Tribulus terrestris was investigated on nucleation and the growth of the calcium oxalate (CaOx) crystals as well as on oxalate induced cell injury of NRK 52E renal epithelial cells. RESULTS: Tribulus terrestris extract exhibited a concentration dependent inhibition of nucleation and the growth of CaOx crystals. When NRK-52E cells were injured by exposure to oxalate for 72 h, Tribulus terrestris extract prevented the injury in a dose-dependent manner. On treatment with the different concentrations of the plant, the cell viability increased and lactate dehydrogenase release decreased in a concentration dependent manner. CONCLUSION: The current data suggests that Tribulus terrestris extract not only has a potential to inhibit nucleation and the growth of the CaOx crystals but also has a cytoprotective role. Our results indicate that it could be a potential candidate for phytotherapy against urolithiasis.

Conjugation of Docetaxel with Multiwalled Carbon Nanotubes and Codelivery with Piperine: Implications on Pharmacokinetic Profile and Anticancer Activity.

Abstract: Nanotechnology-based drug products are emerging as promising agents to enhance the safety and efficacy of established chemotherapeutic molecules. Carbon nanotubes (CNTs), especially multiwalled CNTs (MWCNTs), have been explored for this potential owing to their safety and other desired attributes. Docetaxel (DTX) is an indispensable anticancer agent, which has wide applicability in variety of cancers. However, the potential of DTX is still not completely harvested due to problems like poor aqueous solubility, low tissue permeability, poor bioavailability, high first pass metabolism, and dose-related toxicity. Hence, it was proposed to attach DTX to MWCNTs and coadminister it along with piperine with an aim to enhance the tissue permeation, anticancer activity, and bioavailability. The Fourier transform infrared, UV, and NMR spectroscopic data confirmed successful conjugation of DTX to MWCNTs and adsorption of piperine onto MWCNTs. The codelivery MWCNT-based system offered drug release moderation and better cancer cell toxicity than that of plain DTX as well as DTX-CNT conjugate. The pharmacokinetic profile of DTX was exceptionally improved by the conjugation, in general, and coadministration with piperine, in specific vis-a-vis plain drug. Hence, the dual approach of MWCNTs conjugation and piperine coadministration can serve as a beneficial option for enhancement of the performance of DTX in cancer chemotherapy.
