Liposomes encapsulating novel antimicrobial peptide Omiganan: Characterization and its pharmacodynamic evaluation in atopic dermatitis and psoriasis mice model.

Omiganan is a novel 12 amino acid synthetic cationic peptide from the cathelicidin family. Omiganan possesses antimicrobial action against a wide range of microbes, including gram-positive and gram-negative bacteria and fungi. Omiganan mainly acts by depolarizing the cytoplasmic membrane, resulting in cellular disruption and death.

Design and pharmacodynamic evaluation of DPK-060 loaded Nanostructured lipid carrier embedded gel for dermal delivery: A novel approach in the treatment of atopic dermatitis.

DPK-060 is a synthetic, 17 amino acid peptide, structurally derived from the human protein kininogen. DPK-060 mainly acts by membrane disruption mechanism, thus demonstrating strong broad-spectrum antimicrobial activity against both gram-positive and gram-negative microbes, including methicillin-resistant S. aureus (MRSA) in-vitro and in-vivo.

Polymer-drug conjugates: Design principles, emerging synthetic strategies and clinical overview.

Adagen, an enzyme replacement treatment for adenosine deaminase deficiency, was the first protein-polymer conjugate to be approved in early 1990 s. Post this regulatory approval, numerous polymeric drugs and polymeric nanoparticles have entered the market as advanced or next-generation polymer-based therapeutics, while many others have currently been tested clinically. The polymer conjugation to therapeutic moiety offers several advantages, like enhanced solubilization of drug, controlled release, reduced immunogenicity, and prolonged circulation.

Development of a dry powder for inhalation of nanoparticles codelivering cisplatin and siRNA in lung cancer.

The current study sought to formulate a dry powder inhalant (DPI) for pulmonary delivery of lipopolymeric nanoparticles (LPNs) consisting of cisplatin and siRNA for multidrug-resistant lung cancer. siRNA against ABCC3 gene was used to silence drug efflux promoter. The formulation was optimized through the quality by design system by nanoparticle size and cisplatin entrapment.

Triple negative breast cancer and non-small cell lung cancer: Clinical challenges and nano-formulation approaches.

Triple negative breast cancer (TNBC) and non-small cell lung cancer (NSCLC) are amongst the most aggressive forms of solid tumors. TNBC is highlighted by absence of genetic components of progesterone receptor, HER2/neu and estrogen receptor in breast cancer. NSCLC is characterized by integration of malignant carcinoma into respiratory system.

Formulation and clinical perspectives of inhalation-based nanocarrier delivery: a new archetype in lung cancer treatment.

Despite tremendous research in targeted delivery and specific molecular inhibitors (gene delivery), cytotoxic drug delivery through inhalation has been seen as a core part in the treatment of the lung cancer. Inhalation delivery provides a high dose of the drug directly to the lungs without affecting other body organs, increasing the therapeutic ratio. This article reviews the research performed over the last several decades regarding inhalation delivery of various cancer therapeutics for the treatment of lung cancer.

Nanocarriers in effective pulmonary delivery of siRNA: current approaches and challenges.

Research on siRNA is increasing due to its wide applicability as a therapeutic agent in irreversible medical conditions. siRNA inhibits expression of the specific gene after its delivery from formulation to cytosol region of a cell. RNAi (RNA interference) is a mechanism by which siRNA is silencing gene expression for a particular disease.

Antimicrobial peptide delivery: an emerging therapeutic for the treatment of burn and wounds.

The management of wounds and burns is becoming difficult using conventional therapeutics available due to resistance development by microbes. Therefore, there is an utmost need to develop therapeutic alternatives to these agents. Antimicrobial peptides have emerged as a novel class of agents for the effective management of wounds and burns due to their potent nature along with minimal chances of resistance development against them.

Targeted delivery of monoclonal antibody conjugated docetaxel loaded PLGA nanoparticles into EGFR overexpressed lung tumour cells.

The aim of this study was to develop anti-EGFR antibody conjugated poly(lactide-co-glycolide) nanoparticles (NPs) to target epidermal growth factor receptor, highly expressed on non-small cell lung cancer cells to improve cytotoxicity and site specificity. Cetuximab was conjugated to docetaxel (DTX) loaded PLGA NPs by known EDC/NHS chemistry and characterised for size, zeta potential, conjugation efficiency and the results were 128.4 ± 3.

Intranasal delivery of tapentadol hydrochloride-loaded chitosan nanoparticles: formulation, characterisation and its in vivo evaluation.

The aim of the present investigation was to formulate tapentadol hydrochloride-loaded chitosan nanoparticles (CS-NPs) for nose to brain delivery. Chitosan nanoparticles were prepared using ionotropic gelation technique. Optimisation of the formulation and process parameters was done using Box-Behnken Design.
