Tumor Targeting With Peptide-Drug Conjugates: Showcasing Key Progress And Hurdles, Keykavous Parang, Thuy Do, Clare Dinh, Dorna Davanidavari, Max Foroughi, Troy Khong, Mahsa Moazen, Amir Nasrolahi Shirazi

Pharmacy Faculty Articles and Research

Peptide-drug conjugates (PDCs) are modular, targeted therapeutics composed of a homing peptide linked to a cytotoxic or modulating drug payload via a cleavable/non-cleavable linker. PDCs utilize peptide targeting to enhance the delivery of potent drugs to tumors, providing advantages such as superior tissue penetration, reduced immunogenicity, and simpler manufacture compared to antibody-drug conjugates (ADCs). A comparison of PDCs versus ADCs highlights that PDCs’ small size (~1-3 kDa) enables deeper tumor penetration and faster clearance, whereas ADCs (~150 kDa) benefit from prolonged circulation but suffer from limited tissue diffusion. This review surveys recent advances in PDC design and application. We discuss …

Development And Optimization Of Moxifloxacin Solid Lipid Nanoparticles Via Double Emulsion Organic Solvent Free Technique Applying Box–Behnken Experimental Design, Esraa M. Elshazly, Mona G. Arafa, Samia A. Nour

Pharmacy

The current research proposes the preparation of Moxifloxacin-loaded solid lipid nanoparticles through a solvent-free double emulsion technique, to overcome chronic wound healing limitation. The independent variables: stearic acid, Span 80, and Tween 80 were optimized via Box–Behnken design, based on entrapment efficiency (EE%), zeta potential (ZP), and particle size (PS). To statistically optimize the formulation variables, a three-factor, three-level (3³) design involving 15 runs was employed and optimization was carried out to attain maximum EE% and ZP and minimum PS yielding an overall desirability of 0.851. Results indicated that increasing stearic acid enhanced EE%, Span 80 increase PS, and Tween …

Application Of Bioactive Materials Primary Cilia As A Novel Delivery Vehicle, Ayan K. Barui, Farideh Amirrad, Vansh Goel, Sharareh Ohadi, Rajasekharreddy Pala, Ashraf M. Mohieldin, Andromeda M. Nauli, Surya M. Nauli

Pharmacy Faculty Articles and Research

Primary cilia are hair-like structured cell organelles functioning as cellular antennae with chemosensory and mechanosensory roles. Dysfunction of cilia results in ciliopathies, including renovascular diseases (polycystic kidneys, hypertension, aneurysm), mental impedances (Alzheimer's disease, Parkinson's disease, dementia), metabolic diseases (obesity, developmental skeleton defects), blindness, and so on. With a diameter of 150 nm, cilia can be cleaved, released and circulated in the body as injury biomarkers. We here assessed the potential use of isolated cilia as a novel delivery vehicle. Cilia were isolated from renal epithelial cells, and a specific-targeting chemotherapeutic was designed on the cilia. The data show a remarkable …

Fluorescent Labeling And Size-Dependent Uptake Of Mesoporous Silica Nanoparticles In Ovarian Cancer Tumor Spheroids, Kimberly R. Berardis

Honors Scholar Theses

Ovarian cancer is the most lethal gynecologic malignancy, with most patients presenting at an advanced stage. While surgical debulking improves survival, nonresectable tumors (<1 cm) contribute significantly to morbidity and remain difficult to treat. Nanocarrier-based drug delivery systems offer an innovative approach to targeted therapy and palliation. In vivo models have demonstrated that intraperitoneally delivered mesoporous silica nanoparticles (MSNs) preferentially accumulate in tumors with low systemic exposure, enabling targeted chemo- and radiotherapy.

MSNs are particularly suited for radiotherapeutic delivery, as their strong interactions with tumor extracellular matrices drive selective uptake. Additionally, they exhibit excellent stability under neutron flux, allowing for loading with stable isotopes and irradiation immediately prior to administration. High radionuclide retention after dilution further minimizes systemic exposure and toxicity.

A key …

Potential Of Jamu In Nanotechnology Perspective As An Alternative Treatment For Covid-19, Dhadhang Wahyu Kurniawan, Azis Ikhsanudin

Pharmaceutical Sciences and Research

The world seems to be recovering at this time, especially because of the 2019 global coronavirus disease pandemic (COVID-19) caused by the Coronavirus 2 virus (SARS-CoV-2). This virus is similar to other β-coronaviruses through several steps to enter and bind angiotensin-converting enzyme 2 (ACE2) as the main receptor. This binding, particularly in the respiratory epithelium and alveoli of the lungs, affects harmony in human host cells. No specific vaccines and antivirals are available to date as drug investigations are still ongoing. However, many Indonesians consume herbal medicine, especially 'empon-empon' containing the Zingiberaceae family, to protect their health from COVID-19. So …

Development Of Diverse Size And Shape Rna Nanoparticles And Investigation Of Their Physicochemical Properties For Optimized Drug Delivery, Daniel L. Jasinski

Theses and Dissertations--Pharmacy

RNA nanotechnology is an emerging field that holds great promise for advancing drug delivery and materials science. Recently, RNA nanoparticles have seen increased use as an in vivo delivery system. RNA was once thought to have little potential for in vivo use due to biological and thermodynamic stability issues. However, these issues have been solved by: (1) Finding of a thermodynamically stable three-way junction (3WJ) motif; (2) Chemical modifications to RNA confer enzymatic stability in vivo; and (3) the finding that RNA nanoparticles exhibit low immunogenicity in vivo.

In vivo biodistribution and pharmacokinetics are affected by the physicochemical …

Calcium Phosphate As A Key Material For Socially Responsible Tissue Engineering, Vuk Uskoković, Victoria M. Wu

Pharmacy Faculty Articles and Research

Socially responsible technologies are designed while taking into consideration the socioeconomic, geopolitical and environmental limitations of regions in which they will be implemented. In the medical context, this involves making therapeutic platforms more accessible and affordable to patients in poor regions of the world wherein a given disease is endemic. This often necessitates going against the reigning trend of making therapeutic nanoparticles ever more structurally complex and expensive. However, studies aimed at simplifying materials and formulations while maintaining the functionality and therapeutic response of their more complex counterparts seldom provoke a significant interest in the scientific community. In this review …

Mdr1 Sirna Loaded Hyaluronic Acid-Based Cd44 Targeted Nanoparticle Systems Circumvent Paclitaxel Resistance In Ovarian Cancer, Xiaoqian Yang, Arun K. Iyer, Amit Singh, Edwin Choy, Francis J. Hornicek, Mansoor M. Amiji, Zhenfeng Duan

Pharmaceutical Sciences Faculty Publications

Development of multidrug resistance (MDR) is an almost universal phenomenon in patients with ovarian cancer, and this severely limits the ultimate success of chemotherapy in the clinic. Overexpression of the MDR1 gene and corresponding P-glycoprotein (Pgp) is one of the best known MDR mechanisms. MDR1 siRNA based strategies were proposed to circumvent MDR, however, systemic, safe, and effective targeted delivery is still a major challenge. Cluster of differentiation 44 (CD44) targeted hyaluronic acid (HA) based nanoparticle has been shown to successfully deliver chemotherapy agents or siRNAs into tumor cells. The goal of this study is to evaluate the ability of …
