A study has been undertaken with an aim to isolate potent endophytic fungi from mangrove plant Lumnitzera racemosa Linn. Among the 10 different fungal strains isolated, one potent strain with broad-spectrum antagonistic activity was found. Basing on the morphological, cultural and molecular characteristics, the potent fungal strain was identified as Cladosporium cladosporioides. Production of bioactive metabolites by the strain was high in Malt Extract Broth compared to other media tested. The culture utilized Mannitol and Beef extract as good carbon and Nitrogen sources for the elaboration of bioactive metabolites. The optimum pH and Temperature for bioactive metabolite production of the strain were recorded at 4.0 and 30 °C. The secondary metabolites produced by the strain grown under optimal conditions exhibited high antagonistic activity against gram-positive as well as Gram-negative bacteria and fungi. This is the first report of Cladosporium cladosporioides from mangrove plant Lumnitzera racemosa...

The main objective of this research work was to check the presence or absence of the phytochemical chemicals in all the selected medicinal plant. Phytochemical analysis of these plants confirm the presence of various phytochemicals like saponins, tannins, amino acids, phenols, carbohydrates, proteins, flavonoids, steroids, alkaloids and glycosides. A. catechu extract are analyzed by using TLC with varying solvent systems. It was another test Column chromatography, Chloroform: methanol (2:8) gave three and six fractions. In FTIR, the functional groups such as 1º, 2º amines, amides, carboxylic acids, alkanes, 1º amines, nitro compounds, aliphatic amines, and alkyl halides and searched the identity of secondary metabolites, which may act as 3,7-Diacetyl-1,5-Dimethyl-3,7-Di azabicyclo- [3,3,1] Nonan-9-One compound and clearly indicates that phytochemical. Chemical constituents of eleven compounds were identified in the methanol extract. The major components were 3, 7-Diacetyl-1, 5-Dimethyl-3, 7-Di azabicyclo- [3, 3, 1] Nonan-9-One (27.80 and C13H20O3N2). The results were obtained suggest that, in addition to their pharmaceutical and medicine sources of 3, 7-Diacetyl-1, 5-Dimethyl-3, 7-Di azabicyclo- [3, 3, 1] Nonan-9-One...

Iontophoresis assisted drug delivery system refers to a novel system for delivery of the drug in a non-invasive and effective manner across the skin or biological membranes by electrical assistance. Drug substances exhibiting low trans-corneal (ocular) permeability can be effectively delivered in a safe, fast, and painless manner by the employment of electric current of low intensity, which enhances permeation of drugs across the cornea and thereby, extends the duration of drug action. Fundamental principles of physics guide the technique of ocular iontophoresis that repulsion occurs between the ionic charges of the same nature, while attraction occurs between the ionic charges of opposite nature. Electro-repulsion and electro-osmotic flow are the two transport mechanisms on which ocular iontophoresis works. For the ocular delivery of the drug, there are various iontophoresis devices available in the market, e.g., Eyegate® II and OcuPhore®, those are the most commonly used delivery devices for this purpose, while VisulexTM is another similar system. On the basis of the site of application, ocular iontophoresis can be classified...

Eplerenone is a poorly soluble drug that belongs to class II biopharmaceutical classification system. It is a selective aldosterone receptor antagonist, which binds to the mineralocorticoid receptor and blocks the binding of aldosterone, thereby decreases the sodium resorption and subsequently increasing water outflow. This leads to a decrease in blood pressure and used in congestive heart failure. The aim of the present study was to improve the solubility, dissolution and permeability properties of Eplerenone by liquisolid compacts, thereby enhancing oral bioavailability. Different formulations of Liquisolid were developed by dissolving the drug in mixture of Transcutol HP: Capmul MCM and Cremophor EL: Capmul MCM (Non-volatile liquid; 1:1 ratio), converting this liquid medication using carriers as fujicalin and neusilin and coating material as syloid FP 244. The results showed that Liquisolid formulation exhibited significantly higher drug dissolution rate compared to pure drug as well as marketed formulation. The plasma concentration-time profile of healthy Wister rats indicated that the oral bioavailability of optimized formulation has been significantly improved compared to pure drug...

The present work is focused on the formulation of Febuxostat fast dissolving tablets by lyophilization technique using natural starch extracted from Sterculia foetida seeds. Starches were extracted using the alkali method, i.e., sodium hydroxide at 0.1%, 0.25%, and 0.5% concentrations and water from Sterculia foetida seed powder. These starches were evaluated for phytochemical and physicochemical tests. Tablets were prepared using Febuxostat, Sterculia foetida seed starch, and croscarmellose sodium in various concentrations using direct compression technique. Various pre and post-compression parameters were performed along with in vitro drug release studies, characterization studies like FTIR, DSC, SEM, XRD, and accelerated stability studies. Phytochemical tests revealed the presence of only starch in all the extracts. The starch prepared from 0.1% sodium hydroxide (SFS2) showed the best physicochemical properties. From in vitro dissolution studies, it was observed that formulations FS6 and FS12 containing 15% w/w of SFS2 and 15% w/w of croscarmellose sodium respectively showed faster disintegration and enhanced dissolution rate compared with other formulations. Febuxostat tablets were further prepared by lyophilization technique....
