Polymyxin B and Cerexin A are two polypeptide antibiotics, the first one discovered and incorporated quite earlier and the later one has still not been used in clinical trials for its high cytotoxic nature. Although Polymyxin was discovered very earlier but in the mid-way for some time it had lost its importance and was not used frequently due to its narrow spectra of action that only acts on gram negative microbes and because of its toxicity level. But with several new resistant gram negative microbes coming into the limelight responsible for causing many infections, Polymyxin B (the least toxic of all Polymyxins) has again been started to be used in pharmaceutical formulations and drugs. In this project, both Bacillus polymyxa and Bacillus cereus responsible for production of Polymyxin B and Cerexin A respectively were isolated from the rhizosphere of grass and cultured in the lab. They were confirmed by biochemical tests and then used to produce the corresponding antibiotics by submerged fermentation. The crude antibiotic thus obtained were purified by various methods like adsorption through activated charcoal, acetone precipitation, dialysis, Ion Exchange and Sephadex column chromatography and the results were compared to find the best possible way to purify the antibiotics keeping in mind that they show the maximum activity as possible on a lab scale. Further work on Cerexin A was not possible due to the unavailability of its standard solution. Work was carried out for quantitative estimation of purified and crude Polymyxin B by performing spectrophotometric assay against standard polymyxin.

The present study was designed to screen anti-depressant activity of Hydro alcoholic extract of Triticum Aestivum using Chronic models (14 day study) of Tail suspension test (TST) and Forced Swim Test (FST) in Swiss Albino rats. Wheat grass were collected and authenticated. Extraction of dried wheat grass was carried out using a Soxhlet apparatus to obtain its Hydro alcoholic extract. The extract of Triticum Aestivum showed the significant anti-depressant activity comparable to the standard drug. The oral administration of Triticum Aestivum extract at doses 200 mg/kg & 400 mg/kg respectively as compared to the control treated group showed an anti-depressant activity comparable to that of standard drug.
The anti-depressant effects of Triticum Aestivum extract seem to be mainly associated with the activation of dopaminergic system and possess potential anti-depressant activity.

Cancer is a class of diseases characterized by out-of-control cell growth. Cancer cells damage the body by multiplying their cells uncontrollably to form masses of tissue named as tumor. Tumors cells can grow and interfere with the digestive, nervous, and circulatory systems, and they can release hormones that alter body function. Tumors that are severe to body are called cancerous tumors, and temporary cells that are affected to body are not harmful and called as benign tumors. Nearly 100’s of cancers are known to be effecting the humans. According to this concern the presented review outlines the novel anticancer agents how they are useful, their mechanism, and chemistry has briefly discussed in this article, the main aim of these review is to evaluate the complete novel anticancer drugs under single review paper.

A highly sensitive, selective, reproducible, rapid and stability indicating RP-HPLC and spectrophotometric method has been developed and validated successfully for quantitative evaluation of ivabradine hydrochloride formulations. Chromatography was carried out at 25ºC on a 250 mm x 4.6 mm, 5µm, C18, 100Aº Kromasil column with phosphate buffer pH 7.4: methanol:: 35:65 and U.V. detector at λmax 286 nm. In HPLC method the retention time was about 7.4 minutes. Complete validation study for both the methods was carried out according to ICH guideline. Both methods were found to be selective, linear, accurate and precise in the specified ranges. Linearity of both the methods was achieved in the range 5 to 60 μg/ml with a correlation coefficient (r2) ≥ 0.999. The LOD and LOQ of HPLC method were 0.05 and 0.2 µg/ml, respectively. Intra-day and inter-day variability for both methods were <2% RSD. These methods were successfully used for quantification of ivabradine in drug-release studies from immediate-release tablets and controlled-release (CR) formulations.

Simply receiving a diagnosis of a rare disease often becomes a frustrating quest, since many doctors may have never before heard of or seen the disease. This is, however, a time of great progress and hope. Biopharmaceutical research is entering an exciting new era with a growing understanding of the human genome. Scientific advances have given researchers new tools to explore rare diseases, which are often more complex than common diseases.
“Who else has this rare disease? How many of us are there? What can I expect now? What is known or not known about this disease?” These are among the questions that patients and family members ask as they become, out of necessity, advocates for themselves or others.

Background: The World Health Organization (WHO) has named cancer as one of the most significant cause of death presently, with about 6 million reported deaths in 1996, 11.4 million deaths in 2004, 7.6 million deaths in 2008 and 8.2 million deaths in 2012. However, present postulations reveal that there might be an escalation of cancer mortality to about 15 million by 2030, if the progression of the ailment is not checked. Aim: The aim of this study is to evaluate the synergic antiproliferative and cytostatic effects of these fruit (Ananas comosus, Citrullus lanatus and Citrus sinensis) juices. Materials and Method: The study was performed on rapidly proliferating seeds of Sorghum bicolor and the resulting mean radicle lengths (mm) were taken after 24, 48 and 72 hours. Result: The seeds treated with methotrexate showed a significant (P<0.05) inhibition of radicle length growth throughout the experiment, compared with the control seeds radicle. The rate of inhibition after 72 hours was 85.39%. The juice doses of 20 and 40% showed a significant (P<0.05) inhibition of seeds radicle length throughout the 72 hours of study. The inhibition rate was however higher after 72 hours with percentage inhibition of 87.19% at 20% juice concentration and 99.50% at 40% concentration. However, juice concentrations of 60 and 80% gave a cytostatic effect (i.e no radicle growth) throughout the study. Conclusion: The study has shown that A. comosus, C. lanatus and C. sinensis mixed juice has a potential for eliciting antiproliferative and cytostatic effects on rapidly proliferating cells.

Oral route has been the most popular and successfully route for controlled delivery of drugs because of the flexibility in the designing of dosage form than other routes. The immidiate release conventional dosage form lack in the efficiency of controlling the proper plasma drug concentration. This factor as well as factors such as repetitive dosing ++and unpredictable absorption leads to the concept of oral controlled release drug delivery systems. A desirable characteristic of controlled release delivery system is that the duration of drug action should be dictated by the design property of drug molecules. There are different mechanistic aspects for design of oral controlled release drug delivery systems such as matrix, reservoir, osmotic pressure, ion exchange resins, altered density etc. This article contains brief review on currently existing oral controlled system and various formulation approaches for the controlled release system.
