Article Abstract
Raspberry ketone (RK), derived from red raspberry fruit (, family Rosaceae), is a reported potent antiobesity agent. This study aims to investigate method development, validation, and and pharmacokinetics in rats. LC-MS/MS was used to conduct method development, validation, stability, and oral PK samples of RK in plasma analyses. RK was highly soluble in Tris buffer and stable in gastrointestinal fluids as well as plasma. Rat liver microsomal stability of RK in phase I and II studies was 84.96 ± 2.39 and 69.98 ± 8.69%, respectively, after 60 min. Intestinal permeability was 4.39 ± 1.37 × 10 cm/s. Maximal concentration was 1591.02 ± 64.76 ng/ml, which was achieved after 1 h (time to maximal concentration), and absolute oral bioavailability was 86.28%. Pharmacokinetic data serve as a keystone for preclinical and clinical adjuvant therapy.

Naturally occurring phenols were incorporated into the mycophenolic acid (MPA) core to form sixteen new MPA derivatives. Ester conjugates of MPA with isoeugenol, methyl o-coumarate, and raspberry ketone exhibited the highest antioxidant activity in the DPPH test. These derivatives were then tested against the human pancreatic cancer AsPC-1 cells, showing cytotoxicity similar to that of the referential parent compounds MPA and mycophenolate mofetil (MMF).

Food supplements, particularly for overweight control, are becoming increasingly popular due to rising obesity rates. Raspberry ketone (RK), naturally found in raspberries and other berries, is commonly consumed as food supplement for its potential weight loss benefits. However, fraudulent practices like mislabelling or adulteration are a concern for consumers and, therefore, comprehensive analytical approaches are demanded to ensure the quality of these products.

Type 1 diabetes encompasses a spectrum of metabolic disorders marked by insulin deficiency, resulting in elevated blood glucose levels, commonly referred to as hyperglycemia. This persistent condition often precipitates lipid profile abnormalities, causing cholesterol alterations, low-and high-density lipoproteins, and triglycerides. The liver is particularly vulnerable to increased oxidative stress and inflammatory responses, which activate the transcription of pro-apoptotic genes and ultimately contribute to hepatocyte damage.
