Paclitaxel is a well-known cancer drug that functions as a mitotic inhibitor. This work focuses on a copper based crystal that encapsulates the pharmaceutical agent and serves as a drug delivery agent. A Copper-Pacitaxil chloride (CUPAC) complex is synthesized and tested against the National Cancer Institute's sixty cell line panel. The 10:1 ratio results in a crystal that was examined by Matrix-Assisted Laser Desorption Ionization-Time of Flight Mass Spec (MALDI-TOF-MS), Scanning Electron Microscopy (SEM) and Proton (H) and Carbon (C) Nuclear Magnetic Resonance (NMR). The potential attributes of a copper based crystal as an in vivo drug carrier for Paclitaxel are discussed.

One of the main difficulties in nanotechnology is the development of an environmentally friendly, successful method of producing nanoparticles from biological sources. Silver-doped zinc oxide nanoparticles (Ag-ZnO NPs), with antibacterial and antioxidant properties, were produced using Adiantum venustum extract as a green technique. Fresh A.

Hydrogen sulfide (HS) is a gas signaling molecule with versatile bioactivities; however, its exploitation for disease treatment appears challenging. This study describes the design and characterization of a novel type of HS donor-drug conjugate (DDC) based on the thio-ProTide scaffold, an evolution of the ProTide strategy successfully used in drug discovery. The new HS DDCs achieved hepatic co-delivery of HS and an anti-fibrotic drug candidate named hydronidone, which synergistically attenuated liver injury and resulted in more sufficient intracellular drug exposure.

Microneedles (MNs) serve as a revolutionary paradigm in transdermal drug delivery, heralding a viable resolution to the formidable barriers presented by the cutaneous interface. This review examines MNs as an advanced approach to enhancing dermatological pathology management. It explores the complex dermis structure and highlights the limitations of traditional transdermal methods, emphasizing MNs' advantage in bypassing the stratum corneum to deliver drugs directly to the subdermal matrix.

The respiratory tract is susceptible to various infections and can be affected by many serious diseases. Vaccination is one of the most promising ways that prevent infectious diseases and treatment of some diseases such as malignancy. Direct delivery of vaccines to the respiratory tract could mimic the natural process of infection and shorten the delivery path, therefore unique mucosal immunity at the first line might be induced and the efficiency of delivery can be high.

Leber's hereditary optic neuropathy (LHON) is an ocular mitochondrial disease that involves the impairment of mitochondrial complex I, which is an important contributor to blindness among young adults across the globe. However, the disorder has no available cures, since the approved drug idebenone for LHON in Europe relies on bypassing complex I defects rather than fixing them. Herein, mRNA-loaded nanoparticle (mNP)-engineered mitochondria (mNP-Mito) were designed to replace dysfunctional mitochondria with the delivery of exogenous mitochondria, normalizing the function of complex I for treating LHON.
