Transdermal delivery of therapeutics has been identified by scientific researchers as an alternative choice of drug administration, owing to its unique and tremendous benefit over conventional and oral administrations, but its exploration has been limited because of the “skin barricade” as its major challenge. A special formulation that is capable of meeting up and overcoming its associated challenges is required. Nanotechnology is already established as one of the developing areas of technology, and its application in drug delivery has proven overwhelming success. Nanoemulsions are unique nanotechnological formulations that represent a novel drug delivery system towards resolving pharmaceutical challenges as well as improves dermal and transdermal drug delivery. Since the majority of novel drug candidates, especially those phyto-pharmaceutically discovered, are of less solubility and bioavailability, their pharmaceutical applications have been underexplored. This study aims at presenting nanoemulsion as a novel formulation capable of solving undesirable pharmaceutical challenges such as toxicity, first-pass metabolic effect, drug solubility, and bioavailability. Its potential as an exclusive nanocarrier that mobilizes and promotes transdermal therapeutic delivery...

Oral route has always been the preferred route of drug administration in many diseases. This route is limited to those drugs molecules that are permeable across the gastric mucosa and are sparingly soluble. Solubility is an important parameter to achieve the desired concentration of drug in systemic circulation for therapeutic response. As a consequence of modern drug discovery techniques, there has been a steady increase in the number of new active lipophilic compounds that are poorly water-soluble. It is a challenge for a scientist to convert those molecules into an orally administered formulation with sufficient bioavailability. Improving oral bioavailability of poorly water-soluble drugs using self micro emulsifying drug delivery systems (SMEDDS) appears most promising. Currently, various technologies are available to deal with insoluble drugs such as micronization, solid dispersions, complex formation, etc. Among the several approaches, SMEDDS has emerged as a distinctive approach used to improve the bioavailability of hydrophobic drugs. SMEDDS is isotropic mixture of drug, surfactants, cosurfactants, and oil which have unique ability to form fine o/w...

Prostate cancer is one of the most important cancer in men. In most cases, prostate cancer confirmed by histological and transrectal biopsy for the examination of prostatic tissue. Metastatic prostate cancer is second leading cause of death from cancer. Androgen deprivation therapy is common treatment in men with prostate cancer that may cause fatigue, increased body fatness, and loss of lean body tissue. Abiraterone acetate improved overall survival in Metastatic Castration-Resistant Prostate Cancer. Enzalutamide is a novel anti-androgen that is approved for the treatment of Metastatic Castration-Resistance Prostate Cancer after taxane-based chemotherapy. The management options include surveillance, radiotherapy, and radical prostatectomy, but there is no evidence base to evaluate the benefits of each approach. Advanced prostate cancer is managed by hormonal therapy. Active surveillance is a novel and fascinating approach to distinguish between patients who are at higher risk and need active therapy and patients who are at low risk for disease progression. This review provides a short overview of the various approaches of prostate...

Benzimidazoles are well known biologically active N-containing heterocycles, widely used as drugs such as antifungal, antibacterial, antiparasitic, and antihelmintic. In addition, N1 and C2-substituted benzimidazoles and their derivatives have been found to be potent biologically active compounds as well. Further, N1-substituted benzimidazoles have exhibited anti-microbial, antihelmintic activities and also antiviral activity against human cytomegalovirus and herpes simplex virus type-1. Specifically, N1-substituted benzimidazole like 5,6-dichloro-1-β-D-ribofuranosylbenzimidazole is known for inhibition of transcription elongation by RNA polymerase II. Another N1-substituted benzimidazole derivative called enviroxime [2-amino-1- (isopropyl-sulphonyl)-6-benzimidazole phenyl ketone oxime] was reported to be a potent inhibitor of rhinovirus replication in human embryonic nasal organ cultures. The biological activities of these compounds depend upon the substitution on the benzimidazole at the N-1 or C-2 position. Since the benzimidazole heterocyclic ring system mimics the purine bases like adenine and guanine of nucleic acids, the N1-substituted benzimidazole may incorporate into viral nucleic acid by enzymatic process and subsequently can alter the structure and/ or function of viral...

Laccase belongs to polyphenol oxidases, which is a very wide family of copper-containing atoms in the center, which serves as the catalytic site. It is biochemically a glycoprotein with molecular mass being between 50kda to 130kda and 30% carbohydrate content, in addition to this it has three types of copper atoms. It is one of the most important enzymes due to its role in the food industry. It acts as a biosensor where it can detect morphine, codeine, catecholamine, and many other enzymes. In insects, it performs the function of cuticle sclerotization. Moreover, laccase is safe for human consumption. The most important factor which has prevented laccase from being insanely famous is the cost that is associated with using a very large quantity of laccase. Laccases can be extracted from almost all kinds of white-rot fungi as well as from various other fungi species such as Pycnoporus cinnabarinus, Gloeophyllum trabeum but not in any brown-rot species except Coniophora puteana as was recently discovered. Aspergillus niger, Aspergillus oryzae and Trichoderma...
