Article Abstract

The optimization of a series of S1P1 agonists with limited activity against S1P3 is reported. A polar headgroup was used to improve the physicochemical and pharmacokinetic parameters of lead quinolinone 6. When dosed orally at 1 and 3 mg/kg, the azahydroxymethyl analogue 22 achieved statistically significant lowering of circulating blood lymphocytes 24 h postdose. In rats, a dose-proportional increase in exposure was measured when 22 was dosed orally at 2 and 100 mg/kg.

Where possible, antimicrobials, such as clindamycin, should be given orally rather than intravenously when efficacy will be equivalent. A single-centre pre-/post-intervention study was conducted. There were 11 134 patients admitted to included wards during the study period.

Objectives: The absorption of conventional cholecalciferol may be impaired in patients with inflammatory bowel disease (IBD). The bioavailability and optimal dosing of buccally absorbable nanoemulsion vitamin D in this population remain unclear. This study aimed to compare the effects of buccal nanoemulsion and conventional oral vitamin D supplementation on serum 25-hydroxyvitamin D (25OHD) levels in patients with IBD.

ROSAH (retinal dystrophy, optic nerve edema, splenomegaly, anhidrosis, and headache) syndrome is a rare genetic disease caused by variants in alpha-kinase 1 (ALPK1) resulting in downstream pro-inflammatory signaling mediated by the TIFA/TRAF6/NF-κB pathway. Here, we report the design of an ALPK1 inhibitor, DF-003, with pharmacokinetic properties suitable for daily oral dosing. In biochemical assays, DF-003 potently inhibits human ALPK1 (IC = 1.

Remimazolam is an ultrashort-acting benzodiazepine approved for procedural sedation in 2020 by the US Food and Drug Administration; however, dosing information originating from the US is limited. No existing literature details infusion rates of remimazolam delivered by manually adjusted infusion pumps. This case report describes the administration of manually infused remimazolam to an 86-year-old man for the surgical extraction of third molars under procedural sedation.
