Nanoformulation design and therapeutic potential of a novel tubulin inhibitor in pancreatic cancer.

Successful treatment of pancreatic cancer remains a challenge due to desmoplasia, development of chemoresistance, and systemic toxicity. Herein, we synthesized (6-(3-hydroxy-4-methoxylphenyl)pyridin-2-yl) (3,4,5-trimethoxyphenyl)methanone (CH-3-8), a novel microtubule polymerization inhibitor with little susceptible to transporter-mediated chemoresistance. CH-3-8 binding to the colchicine-binding site in tubulin protein was confirmed by tubulin polymerization assay and molecular modeling.

Nanoparticulate delivery of potent microtubule inhibitor for metastatic melanoma treatment.

Melanoma is the most aggressive type of skin cancer, which readily metastasizes through lymph nodes to the lungs, liver, and brain. Since the repeated administration of most chemotherapeutic drugs develops chemoresistance and severe systemic toxicities, herein we synthesized 2-(4-hydroxy-1H-indol-3-yl)-1H-imidazol-4-yl)(3,4,5-trimethoxyphenyl) methanone (abbreviated as QW-296), a novel tubulin destabilizing agent with little susceptible to transporter-mediated drug resistance. QW-296 disturbed the microtubule dynamics at the nanomolar concentration in A375 and B16F10 melanoma cells.

Biomedical Applications of Electrospun Nanofibers: Drug and Nanoparticle Delivery.

The electrospinning process has gained popularity due to its ease of use, simplicity and diverse applications. The properties of electrospun fibers can be controlled by modifying either process variables (e.g.

The fourth annual BRDS on genome editing and silencing for precision medicines.

Precision medicine is promising for treating human diseases, as it focuses on tailoring drugs to a patient's genes, environment, and lifestyle. The need for personalized medicines has opened the doors for turning nucleic acids into therapeutics. Although gene therapy has the potential to treat and cure genetic and acquired diseases, it needs to overcome certain obstacles before creating the overall prescription drugs.

Comparison of electrospun and solvent cast polylactic acid (PLA)/poly(vinyl alcohol) (PVA) inserts as potential ocular drug delivery vehicles.

Purpose: The purpose of this work was to develop, characterize and compare electrospun nanofiber inserts (ENIs) and solvent cast polymeric inserts (SCIs) for ocular drug delivery.

Methods: ENI and SCI of 1%, 5% and 10% w/w dexamethasone were fabricated using a blend of poly-lactic acid (PLA) and poly-vinyl alcohol (PVA). Inserts were characterized for morphology, thickness, pH, drug content, drug crystallinity, in vitro drug release, sterility, dimethylformamide (DMF) and chloroform content, and cytotoxicity.
