Cancer has been growing nowadays consequently high number of death ascertained worldwide. The medical intervention involves chemotherapy, radiation therapy and surgical removal. This conventional technique lacking targeting potential and harm the normal cells. In drug treatment regimen, the combination therapy is preferred than single drug treatment module due to higher internalization of chemotherapeutics in the cancer cells both by enhance permeation retention effect and by direct cell apoptosis. The cancer therapeutics involves different methodologies of delivering active moiety to the target site. The active and passive transport mode of chemotherapeutic targeting utilizes advance nanocarriers. The nanotechnological strategic treatment applying advance nanocarrier greatly helps in mitigating the cancer prevalence. The nanocarrier-incorporating nanodrug directed for specific area appealed scientist across the globe and issues to be addressed in this regard. Therefore, various techniques and approaches invented to meet the objectives. With the advances in nanomedicine and drug delivery, this review briefly focused on various modes of nanodrug delivery including nanoparticles, liposomes, dendrimer, quantum dots, carbon nanotubes, metallic nanoparticles, nanolipid carrier (NLC), gold nanoshell, nanosize cantilevers and nanowire that looks promising and generates a novel horizon in cancer therapeutics.

Comprehensive pharmacological screening of curcumin (CUR) has given the evidence that it is an excellent naturally occurring therapeutic moiety for cancer. It is very well tolerated with insignificant toxicity even after high doses of oral administration. Irrespective of its better quality as an anticancer agent, therapeutic application of CUR is hampered by its extremely low-aqueous solubility and poor bioavailability, rapid clearance and low-cellular uptake. A simple means of breaking up the restrictive factor of CUR is to perk-up its aqueous solubility, improve its bioavailability, protect it from degradation, and metabolism and potentiate its targeting capacity towards the cancer cell. The development in the field of nanomedicine has made excellent progresses toward enhancing the bioavailability of lipophilic drugs like CUR. Nanoparticles (NPs) are capable to deliver the CUR at specific area and thereby prevent it from physiological degradation and systemic clearance. In recent year, an assortment of nanomedicine-based novel drug delivery system has been designed to potentiate the bioavailability of CUR towards anticancer therapy. In this review, we discuss the recent development in the field of nanoCUR (NanoCur), including polymeric micelles, liposome, polymeric NPs, nanoemulsion, nanosuspension, solid lipid NPs (SLNPs), polymer conjugates, nanogel, etc. in anticancer application.

Olive (Olea europaea Linn., Fam. Oleaceae) is commonly known as Zaytoon in Mediterranean region. Its fruits and oil are essential components of Mediterranean diets. Olive tree is a prevalent plant species and one of the important cultivated crops of Mediterranean region. Oleuropein is a phenolic constituents of olive, which, along with its related compounds, has been indicated to be majorly responsible for its beneficial effects. Oleuropein is a secoiridoid type of phenolic compound and consists of three structural subunits: hydroxytyrosol, elenolic acid, and a glucose molecule. It is also reported to be the chemotaxonomic marker of olive. The oleuropein is reported to possess a number of biological activities including action against dyslipidemia, antiobesity, antidiabetic, antioxidant, antiatherogenic, antihypertensive, antiinflammatory, and hepatoprotective actions. The scientific evidence supports the role of oleuropein as a potential agent against metabolic syndrome. The present review discusses chemistry of oleuropein along with potential role of oleuropein with reference to pathophysiology of metabolic syndrome.

Background: Acne vulgaris is a common chronic skin disease that affects around 9.4% (approx. 650 million people) of the global population. Growing research in the field of nanomedicine over the years has now been exploited in management of various human disorders. The nanomedicine concept has an immense opportunity for the effective management and control of acne disease by designing a novel, low-dose topical delivery system. Topical nanoemulsion-based gel preparations are said to have various benefits over the conventional formulations. The recent patents on topical anti-acne formulation (US 7241456B2; US 6897238B2; US 6284234B1) provided the concept to design thymol loaded nano-emulgel for topical application in acne. Methods: The objective of the current investigation was to design a thymol loaded nanoemulgel preparation by exploiting low-energy emulsification method for topical application in acne. Furthermore, developed formulation was characterized for thermodynamic stability, mean droplet size, zeta potential, drug content and in-vitro drug diffusion study. Results: The optimized thymol loaded nanoemulsion was found to be 13.60±0.117 nm with PdI 0.197±0.008. Nanoemulsions will provide an enormous surface area for better penetration of therapeutic agent into the pilosebaceous region, resulting better efficacy. Conclusion: From the above studies, it concluded that aqueous-based gel vehicle of the developed formulation system exploited for topical delivery has moisturising properties which can improve local tolerability also.
