Supersaturated Drug Delivery System of Oxyberberine Based on Cyclodextrin Nanoaggregates: Preparation, Characterization, and in vivo Application

drug discovery, Today's cyclodextrin,

Today’s cyclodextrin is a fascinating practical application of CDs – how can we create a supersatured drug delivery system (SDDS)?

In this paper, Oxyberberine (OBB) – hydroxypropyl-β-CD SDDS was prepared using the ultrasonic-solvent evaporation method.

The oral relative bioavailability of OBB-HP-β-CD SDDS was also 16 times enhanced compared to that of the raw material. Finally, an in vivo pharmacodynamic assay showed that the anti-hyperuricemic potency of OBB-HP-β-CD SDDS was approximately 5– 10 times higher than that of OBB raw material.

FDA-Approved Alzheimer’s Medications

drug development, drug discovery, , ,

⚫ Alzheimer’s disease takes a toll on not just the people suffering from the disease but also on their loved ones and caregivers in a way that almost no other illness does.

⚫ The Alzheimer’s disease market is projected to experience robust growth at a compound annual growth rate of 20% from $2.2 billion in 2020 to $13.7 billion in 2030!

🔶 Drug Development Pipeline:
🔸 187 current trials assessing 141 unique drugs
🔸 Phase 3: 36 drugs
🔸 Phase 2: 87 drugs
🔸 Phase 1: 31 drugs

🔷 Phase 3 has 36 agents in 55 trials:
🔹 DMT*-Biologics: 9 (25%)
🔹 DMT*-Small molecules: 15 (42%)
🔹 Putative cognitive-enhancers: 5 (14%)
🔹 Neuropsychiatric symptoms: 7 (19%)
*DMT stands for disease-modifying therapies

🔶 Most Common Targets:
🔸 Transmitter receptors, amyloid, synaptic function, and inflammation

🔷 58 new drugs have entered the pipeline in the past year!
🔷 28% of candidate therapies are repurposed from other diseases!

⚫Despite the hype, controversy, and occasional scandal surrounding the approval of Alzheimer’s drugs, and the disappointing reports of the ineffectiveness of recently approved drugs, many companies are still dedicating time and resources to finding a potential cure for this debilitating disease. This gives hope that the future is bright for those living with Alzheimer’s.

Sustained Delivery of Cu(II)-Based DNA Intercalators by Nanometer-Sized Cyclodextrin-Based Porous Polymers

drug discovery, , ,

Apparently, cyclodextrin-based oligonucleotide delivery is becoming a hot research topic. This recent study from University of Nova Gorica – Tina Škorjanc, PhD, Damjan Makuc, Nora Kulak, and Valant Matjaz presents a cyclodextrin porous polymer to form nanometer-sized particles and used as a delivery vehicle for metal-free and Cu(II)-metalated anthraquinone-based DNA intercalators.

Single Residue Variation in Skeletal Muscle Myosin Enables Direct and Selective Drug Targeting for Spasticity and Muscle Stiffness

drug discovery,

Hungary is just a small grain on the beach of the pharma industry, yet from time to time we also make remarkable discoveries.
Today, its Motorpharma Ltd. a spin-off from Eötvös Loránd University that makes us proud by starting to dose their lead compounds MPH-220 to humans in Texas.
Mate Gyimesi, András Málnási-Csizmadia et al first published in 2020 in Cell about MPH-220, whish is targeting skeletal muscle myosin and can enabled muscle relaxation, in human and model systems, without cardiovascular side effects and improved spastic gait disorders after brain injury in a disease model. MPH-220 provides a potential nervous-system-independent option to treat spasticity and muscle stiffness.
Muscle spasticity after nervous system injuries and painful low back spasm affect more than 10% of global population. Current medications are of limited efficacy and cause neurological and cardiovascular side effects because they target upstream regulators of muscle contraction. Direct myosin inhibition could provide optimal muscle relaxation; however, targeting skeletal myosin is particularly challenging because of its similarity to the cardiac isoform.

Treatment of hypertriglyceridemia with 2-hydroxypropyl-beta-cyclodextrin

drug development, drug discovery,

Fascinating therapeutic application of cyclodextrins have been published by Beren Therapeutics. Earlier the company already patented the use in the therapy of familial hypercholesterolemia, now they propose using hydroxypropyl-BCD against hypertriglyceridemia.
In the 2nd patent composition and purification is reported of a compounds that has a surprisingly high DS (DS-10 being the main component), which composition is far from the materials used as excipients.

Antibiotics in the clinical pipeline as of December 2022

drug discovery,

Do you think we are putting enough effort in developing novel antibiotics?
The need for new antibacterial drugs to treat the increasing global prevalence of drug-resistant bacterial infections has clearly attracted global attention, with a range of existing and upcoming funding, policy, and legislative initiatives designed to revive antibacterial R&D. Despite the promising early-stage antibacterial pipeline, it is essential to maintain funding for antibacterial R&D and to ensure that plans to address late-stage pipeline issues succeed.
