Published: September 2011

Bifunctional, pH-activatable BODIPY dyes were developed and incorporated in mannose cluster-containing activity-based probes for cysteine proteases. Mannose receptor-dependent uptake of the probes in dendritic cells, followed by trafficking to acidic cellular compartments resulted in fluorescence as seen by live-cell imaging, and subsequent cathepsin inhibition.

Purpose: Posaconazole is a broad-spectrum antifungal for treating and preventing invasive fungal infections (IFIs) in immunocompromised individuals, including children as young as 2 years. Available in delayed-release (DR) oral suspension, intravenous formulation, and older immediate-release (IR) formulation (off-label in younger children), dosing harmonization across age groups and formulations remains inconsistent. This inconsistency arises from the unique physiology of young children and posaconazole's pH-dependent absorption.

Porcine deltacoronavirus (PDCoV), also known as HKU15, is a swine enteropathogenic virus that is believed to have originated in birds. PDCoV belongs to the genus Deltacoronavirus (DCoV), the members of which have mostly been identified in diverse avian species. We recently reported that chicken or porcine aminopeptidase N (APN), the major cellular receptor for PDCoV, can mediate cellular entry via three pseudotyped retroviruses displaying spike proteins from three avian DCoVs (HKU11, HKU13, and HKU17).

MILs (Materials Institute Lavoisier), as nanocarriers based on metal-organic frameworks (MOFs), are one of the most advanced drug delivery vehicles that are now a major part of cancer treatment research. This review article highlights the key features and components of MIL nanocarriers for the development and improvement of these nanocarriers for drug delivery. Surface coatings are one of the key components of MIL nanocarriers, which play the role of stabilizing the nanocarrier, pH-dependent drug release, increasing the half-life of the drug, and targeting the carrier.

Antibody-drug conjugates (ADCs) represent a promising class of targeted cancer therapeutics that combine the specificity of monoclonal antibodies with the potency of cytotoxic payloads. Despite their therapeutic potential, the use of ADCs faces significant challenges, including off/on-target toxicity and resistance development. This review examines the current landscape of ADC development, focusing on the critical aspects of target selection and antibody engineering.

Prokinetic agents are drugs used to enhance gastrointestinal motility and treat disorders such as Gastroesophageal Reflux Disease (GERD) and gastroparesis. pH-dependent release systems offer targeted drug delivery, allowing prokinetic agents to be released specifically in desired regions of the gastrointestinal tract. This optimizes drug efficacy and minimizes systemic side effects.
