The clinical success of investigational pharmaceuticals remains doubtful due to an unacceptable level of attrition during clinical drug development and declining clinical approval rates. Countless molecules are being withdrawn during drug discovery and clinical trial phases due to poor pharmacokinetics (ADME), lack of safety and efficacy, commercial interests, market competition, and patent protection expiry. Consequently, the novel drug pipelines are running dry. Because huge capital is involved in different clinical trial phases, the task of bringing a new drug or drug formulation to the market is a very costly venture...

Gajanand Sharma, Kanika Thakur, Kaisar Raza, Bhupinder Singh, Om Parkash Katare
Topical drug delivery offers many advantages over oral delivery, such as avoidance of first-pass metabolism, targeting of the active ingredients for a local effect, and patient compliance. However, the achievement of dermal and transdermal delivery needs to conciliate difficulties in permeation across skin barrier at different levels (skin surface, epidermis, dermis, and hypodermis). Nanostructured lipid carriers (NLCs) are recently invented second-generation lipidic carriers. The present article intends to provide an insight of composition, production, and application of these carriers in topical delivery for local and systemic effects...

There have been remarkable improvements in our understanding of cancer biology. However, therapeutic improvements, with a few exceptions, have been minimal. Also, significant challenges remain in translating fundamental discoveries in cancer biology and genetics into effective drugs and cures. Traditional two-dimensional monolayer cell cultures lack predictive value, resulting in a >90% failure rate of compounds in clinical trials. A developing cancer is a symbiotic tissue consisting of cancer cells, including cancer stem cells (CSCs), and cohabitating with the components of its environment to form a tumor microenvironment (TME) niche...

Stimulated by the enormous success of the inorganic complex cisplatin in tumor treatment, interest in metal complexes has recently grown. Within cells, metal complexes can participate in reactions that are not possible with conventional organic substances, and most of them have promising efficacy as anticancer drugs. However, to be effective in vivo metal complexes need adequate delivery systems able to increase their water solubility, the in vivo bioavailability, and the safe delivery to target organs. The present review reports on the state of the art of these new, nonplatinum, anticancer metallodrugs delivered by nanosized vehicles...

REVIEW
Nandhakumar Sathyamoorthy, Magharla Dasaratha Dhanaraju
The mononuclear phagocyte system (MPS) defends the body against the invasion of microorganisms by phagocytosis. In the presence of opsonins, the invading matter is readily recognized by phagocytes because of the interaction between receptors on the phagocytic cell surfaces and the modified conformation of opsonins. The particulate carriers, which are otherwise capable of optimizing drug delivery, are subjected to opsonization and phagocytosis by the MPS immediately following intravenous administration. These drug carriers should remain in the bloodstream in order to spatially locate the drug to the target site and temporally control the drug's release from there on; however, they are devastated by opsonization by serum proteins...
