Future cancer therapy will depend on combination therapy with multiple drugs to achieve maximum effects and minimum toxicity. Due to the complexity and significance of the tumor microenvironment (TME), it is vital to elucidate this complicated environment when designing a co-delivery system. There are numerous potent target sites in the TME to facilitate simultaneous and selective delivery. Currently, nanocarriers are used frequently in co-delivery systems for multiple antitumor treatments. Nanocarriers can efficiently deliver drugs and achieve synergistic effects, but the potent barriers in the TME and their inherent limitations have restricted their use...

Transdermal delivery serves as non-invasive and effortless terminable means for systemic as well as topical drug delivery and finds itself as an option to conventional delivery route. Significant impervious nature of skin is the greatest hurdle for successful delivery of drug molecules to the deeper layers of skin for systemic absorption. Many approaches have been carried out for delivery of a medicament across skin barrier to enhance the efficacy. Among them lipid-based colloidal carriers have gained a unique position for transdermal delivery of drugs and bioactives owing to the presence of epidermal lipids as the chief component within the penetration barrier in high amount...

Dictating the transport of drug carriers and augmenting the drug concentration at the desired anatomical site with high selectivity are worthwhile pursuits of current pharmaceutical research. Such approaches to drug targeting have been classified into passive and active strategies. As discussed in this article, active targeting promises greater selectivity because it exploits the incorporation of appropriate ligands, which are recognized by the target cells. Ligands, such as folate, peptides, transferrin, antibodies and their fragments, sugar, and sugar-mimetics, etc...

Peroxisome proliferator-activated receptors (PPARs) are nuclear transcription factors. They exist in three isoforms (PPAR-α, PPAR-β/δ, and PPAR-Υ) in humans, but mainly PPAR-Υ, and they are expressed in retinal epithelial pigment. PPARs are involved in mediating numerous pathological implications in eye such as diabetic retinopathy (DR), choroidal neovascularization (CNV), glaucoma, diabetic macular edema, and other retinal diseases. Peroxisome proliferator-activated receptors are key players in various biological pathways like lipid degeneration, immune regulation, and reactive oxygen species regulation, regulation of vascular endothelial growth factor, matrixmetalloproteinase-9, and docosahexaenoic acid pathway...

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...

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...
