The present study assessed the topical potential of nanofibers loaded with Mupirocin (MUP) for the treatment of burns. Nanofibers of MUP were composed of Polyvinyl Pyrrolidone (PVP), Gelatin Type-A, and Ethanol using two methods: Solvent casting and Electrospinning. Nanofibers were characterized for Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), Differential scanning calorimetry (DSC), Thermogravimetric analysis (TGA), Drug Content Studies, in-vitro drug permeation, antibacterial and stability studies. The FT-IR studies showed that the Electrospinning technique had a very good mixing of MUP with the polymer. SEM studies showed that the morphology of electrospinning nanofibers had diameters in the range of 70.41 nm- 406.83 nm. The thermal decomposition studies of optimized Nanofiber (E.S.1) were performed by DSC and TGA study and it was found that the formulation had high stability in high-temperature environments. Permeation studies showed that E.S.1 had the highest percentage amount and controlled release of the drug (90 %) up to 8 has compared to other formulations. Nanofibers prepared through the Electrospinning technique showed better antibacterial activity against Staphylococcus aureus as compared to the Solvent casting nanofibers. This research suggested that MUP loaded nanofibers can be potentially used as a topical drug delivery system for the treatment of burns.

The aim of this review is to present the structure of niosome, benefits and drawbacks, fundamentals of niosome preparation and characterization as well as a description of their applications in drug delivery. This review will provide an overview on the increasing interest on niosomes in the field of drug delivery. Drug delivery systems are defined as formulations aiming for transportation of a drug to the desired area of action within the body. The basic component of drug delivery systems is an appropriate carrier that protects the drug from rapid degradation or clearance and thereby enhances drug concentration in target tissues. Drug targeting is a kind of phenomenon in which drug gets distributed in the body in such a manner that the drug interacts with the target tissue at a cellular or subcellular level to achieve a desired therapeutic response at a desire site without undesirable interactions at other sites. This can be achieved by modern methods of targeting the drug delivery system such as niosomes. Niosomes are the type of non-ionic surfactant vesicles, which are biodegradable, non-toxic, more stable and inexpensive, a new approach to liposomes. Their structure similar to liposome and hence they can represent alternative vesicular systems with respect to liposomes. The niosomes have the tendency to load different type of drugs.

The most common type of cancer and the second biggest cause of death is breast cancer. The disease is the leading cause of death in women aged 45 to 55. It's a multi-stage disease in which viruses have a role in one stage. Breast cancer is an illness that affects the sufferer, their family, and the entire community all over the world. Breast cancer has no established cause, however specific risk factors have been found. Age, race, gender, and family history are all fixed and immutable characteristics. Other elements, such as social and familial support, can help to mitigate the harmful effects.The aim of the present study was to investigate the bioactive ligand for the breast cancer treatment against the HER2 and ESR1 proteins by molecular docking studies. HER2 is an oncogene and membrane tyrosine kinase that is overexpressed and gene amplified in about 20% of breast tumours. When active, it sends proliferative and anti-apoptotic signals to the cell. It is the most important factor in the genesis and progression of breast cancer tumours. To carry out this work protein structures were download from the PDB database and ligands three dimensional structures were downloaded from the PubChem database. The docking was performed by using the iGEMDOCK software suit. The binding energies of bioactive molecules from Hibiscus rosa-sinensis were found to be Rutin (-139.779, -102.743), Quercetin (-106.5, -99.7807), Kaempferol (-105.824, -92.5271), Myricetin         (-111.913, -99.603) and Methotrexate (-140.69, -130.165) against HER2 and ESR1 proteins respectively. Lowest energy of Rutin compared to Methotrexate showed highest binding among the other bioactive molecules.The binding energies of the molecules are the sum of hydrogen bond, vanderwaal’s and electrostatic energies that inversely linked to protein-ligand interaction. From the result of the current study we can conclude that among the four bioactive molecule rutin has lowest binding energy so it could be used as an inhibitor of HER2 and ESR1 protein for the treatment of breast carcinoma in future.

Green route for the synthesis of nanoparticles has become more acceptable than the other chemical as well as biological route. In the present study, silver nanoparticle is synthesized using ethanolic extract of Psidium guajava leaves. Further the synthesized silver nanoparticles were characterized by UV-Visible Spec, FT-IR, X-Ray Diffraction FESEM and E-DAX. The results of FT-IR provided evidence of the involvement of phytochemicals present in the leaf extract in the reduction of silver nitrate to silver nanoparticles. XRD confirmed the crystalline structure as well as shape of the synthesized nanoparticle as face-centred cubic. E-DAX profiling helped in determining the presence of elemental silver. The size of the nanoparticle procured by SEM analysis was found to be approximately 30-50 nm in size. Thus, the findings of this study showed that the plant assisted method for silver nanoparticle synthesis is more effective and further application level studies can shed lights on their use in healing of various human ailments.

A biosimilar is the new emerging drug product of the sector of Biologics that comes under speedily evolving area of pharmaceutical industry. It is the generic substitute for original research-based drugs. Since the Biologics are produced by a variety of products more commonly including cells extracted from humans, animals, microorganisms which varies phenotypically therefore they are “similar but not same” to the original product. Being a new product, it produces several challenges in the market including its regulation guidelines, production efficiency, quality management, and safety factors etc. The quality of these products along with its effectiveness and reduced costs are making them more and more popular. Different research is still being going on for enhancing the efficacy of biosimilars due to its more and more usage in the market. Several countries have developed their separate norms for the production and clinical usage of these biosimilars constituting Canada, Japan, Korea, and United States of America etc. The more biologics grab the attention of the eminent scientists for better innovations, the less marketing approval it gets. To enhance such a situation U S Congress passed the Biologics Price Competition and Innovation act 2009 and US FDA allowed “abbreviated pathway” for their approval and India being the most suited manufacturing area has also prepared certain guidelines stated as “Draft Guidelines on Similar Biologics” which were announced in June 2012, by Department of Biotechnology at Boston bio. The regulatory environment for biosimilars continues to evolve, both in recognition of advances in technology/ analytical methods and the availability of new targets for biosimilar development. With the advent of such efforts biosimilars are trying to surround the market. The demanding sector of biosimilars reveals the challenging gateway towards the nanomedicines also which shows that with the advancing biotechnology after these biosimilars, we are heading towards other newly biologically derived products.
