Different Methodology for Preparation of NLCs – A Review

Review Article of Journal of Pharmaceutical Research and Reviews Different Methodology for Preparation of NLCs - A Review R.C.Doijad , S.V.Salve, Patil Anup KIMSDTU's Krishna Institute of Pharmacy, Karad, Maharashtra, India Nanotechnology in the formulation developed exponentially, the main objective or the basic aim has been on therapeutic undertaking, particularly for targetted drug therapy. Nanocarriers are at forefront of the rapidly developing field of nanotechnology with several potential applications in novel drug delivery, also in clinical medicines and research. Solid lipid nanoparticles are at the forefront of the rapidly developing field of nanotechnology with several potential applications in medicinal formulation and other varied sciences. Due to their unique size-dependent properties, lipid nanoparticles offer the possibility to develop new therapeutic effect. The incorporation of drugs into nanocarriers offers a new prototype in drug delivery that could be used for different levels of drug targeting. Nanostructure lipid carriers have attracted expanding scientific and commercial vigilance in the last couple of years as alternate carriers for the pharmaceutical consignment. Today’s new generation of nanostructured lipid carriers (NLCs) consisting of a lipid matrix with a special nanostructured has been developed. This nanostructure improves drug loading and firmly incorporates the drug during storage. The present review gives insights on the definitions and different techniques of preparation of NLCs.

Progress in the application of LOV2 domain in protein interaction

Review Article of Journal of Pharmaceutical Research and Reviews Progress in the application of LOV2 domain in protein interaction Xiao Shao College of Medical , China Three Gorges University, Yichang, 443002, China. Protein-protein interactions (PPIs) and protein complexes formed by interactions are the main accomplishers of various functions of cells. As an important component of biological networks, protein interaction plays an important role in determining life processes such as signal transduction in cells. Although the experimental methods for studying protein interactions are endless, there are still many shortcomings and gaps in the research on the interaction of precisely regulated protein molecules. LOV (Light Oxygen Voltage) is a light-sensitive protein domain originally discovered in the photo of plants for receiving blue light stimulation, transmitting signals, and causing a series of reactions in plants. The LOV domain belongs to a member of the PAS (Per-Arnt-Sim) superfamily and contains two subunits, LOV1 and LOV2. LOV2 is thought to cause a conformational change after receiving light stimulation, primarily responsible for activating the kinase domain. It plays an important role in intracellular signal transduction. In view of the light control and sensitivity of LOV2, which can be used as a research tool in protein interaction processes, the mechanism of action and structural advantages of signal transduction in LOV2 domain in protein interactions are reviewed.

Complexation of diclofenac sodium with hydroxy propyl betacyclodextrin improves its solubility and stability in ampoule solution which is determined by HPLC

Research Article of Journal of Pharmaceutical Research and Reviews Complexation of diclofenac sodium with hydroxy propyl betacyclodextrin improves its solubility and stability in ampoule solution which is determined by HPLC Kahtan J.Hasson Al-Rasheed University College,department of Pharmacy,Baghdad,Iraq Diclofenac sodium injection is widely used in medicine as antinflamatory and antirheumatic agent with a therapeutic value of 25 mg / ml. However, diclofenac sodium is poorly soluble which forms a problem in its manufacturing as an injection. The available commercial products of diclofenac sodium ampoules have used different types of solubilizing agents as benzyl alcohol which is an irritant in a concentration more than 3% while the other manufacturers used propylene glycol which has toxic impurities. In this present work, Diclofenac Sodium injection is prepared by using Hydroxy Propyl Beta Cyclodextrine ; a natural and safe excipient in formulation of ampoule solution which formed an inclusion complex compounds with Diclofenac Sodium ,render it very soluble and more stable. The finished product of ampoules were subjected to the stability study by storing the samples at 40°C and 75% RH for six months and the physico-chemical properties of the samples were tested at different periods. The results showed no change in appearance of the ampoules solution along the study time .In addition a reversed –phase high pressure liquid chromatographic method was developed and applied in studying the behavior of diclofenac Sodium in solution and its resistance to the high temperature challenger. The developed HPLC method was proved to be accurate and able to detect the degradation products of Diclofenac Sodium in solution.

Estimation of Some Phytochemicals in Swietenia macrophylla Leaves

Research Article of Journal of Pharmaceutical Research and Reviews Estimation of Some Phytochemicals in Swietenia macrophylla Leaves *1Ushie O. A, 2Neji, P.

Jigawa State, Nigeria 3Dept of Chemical Sciences, Cross River University of Technology Calabar, Nigeria Extract of the leaf for the detection of the phytochemicals were obtained by soaking 100g of the sample in 250ml ethanol for forty-eight hours with frequent agitation. The phytochemical screening of Swietenia macrophylla showed that tannin, phenol, flavonoid, terpenoids and alkaloids are present in the leaf extract. Quantitative determination of the detected secondary metabolites was carried out to know their percentages in the S. macrophylla leaves.The quantitative estimation of phytochemicals revealed that the various phytochemical constituents present in the leaf extract. In leaf extract of Swietenia macrophylla, the alkaloid content was 0.045 (9%), flavonoids content was 0.062 (12.4%), phenol content was 0.032 (6.4%) and tannin content was 0.043 (8.6%).
