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.

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.

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.
