Dihydroquercetin (DHQ) is a bioflavonoid with high antioxidant, capillary-protective, and anti-inflammatory activity. DHQ has previously been used for treating Middle East respiratory syndrome coronavirus (MERS-CoV) infection and is currently considered a potential regulator of oxidative stress as part of COVID-19 multipurpose therapy. DHQ has a high safety profile but low bioavailability that limits its use. Innovative techniques (liposomization, crystal engineering, etc.) can be used to increase its bioavailability.

Head and neck squamous cell carcinoma (HNSCC) is one of the most common malignant tumors, but clinical drug treatments are limited. The natural product diphyllin was identified as a lead compound suppressing the proliferation of HNSCC cells through phenotypic screening of natural product library. However, further developments of diphyllin as an anti-HNSCC agent were restricted by the weak bioactivity and poor metabolic stability.

Background: Alzheimer's disease (AD) is complex in pathogenesis and related to aging biology, especially in late-onset AD. We identified a novel synthetic curcumin analog TML-6 through the platform of 6 biomarkers of anti-aging, anti-inflammation, and anti-Aβ as the potential AD drug candidate. TML-6 exhibits multi-target effects on AD pathogenesis, including the activation of NrF-2, the regulation of autophagic machinery through mTOR, the inhibition of APP synthesis and reduction of Aβ, the upregulation of ApoE, and the inhibition of microglial activation.

Unlabelled: Although Canada legalized cannabis beverages in 2019, most available research on acute cannabis intoxication derives from dried flower and edible products. The distinct bioavailability and pharmacokinetic properties of phytocannabinoids ingested from beverages, however, contribute to significantly different acute and long-term effects that need to be better understood to ensure consumer safety.
Objective: This review investigates existing cannabis beverage literature, with a particular focus on acute intoxication effects.

Nimodipine (NIMO) is used to treat ischemic nerve injury from subarachnoid hemorrhage (SAH), but its low aqueous solubility limits clinical safety and bioavailability. This study aims to improve NIMO's solubility by preparing inclusion complexes with sulfobutylether-β-cyclodextrin (SBE-β-CD), reducing the limitations of Nimotop injection, including vascular irritation, toxicity, and poor dilution stability. The NIMO-SBE-β-CD inclusion complex (NIMO-CD) was characterized in both liquid and solid states through phase solubility studies and methods including DSC, FT-IR, XRD, and SEM.
