Four new sesquiterpenoids (-) and six known sesquiterpenoids (-), were isolated from the EtOAc phase of the ethanolic extract of . Their structures were established by spectroscopic methods, including 1-D, 2-D NMR and HPLC-MS. All compounds were tested for their anti-inflammatory effect by the inhibition of the activity of NLRP3 inflammasome by blocking the self-slicing of pro-caspase-1, which is induced by nigericin, then the secretion of mature IL-1β, mediated by caspase-1, was suppressed. Unfortunately none of the compounds showed an anti-inflammatory effect.

Role of Abscisic Acid in the Whole-Body Regulation of Glucose Uptake and Metabolism.

Abscisic acid (ABA) is a hormone with a long evolutionary history, dating back to the earliest living organisms, of which modern (ABA-producing) cyanobacteria are likely descendants, which existed long before the separation of the plant and animal kingdoms, with a conserved role as signals regulating cell responses to environmental challenges. In mammals, along with the anti-inflammatory and neuroprotective function of ABA, nanomolar ABA regulates the metabolic response to glucose availability by stimulating glucose uptake in skeletal muscle and adipose tissue via an insulin-independent mechanism and increasing metabolic energy production and also dissipation in brown and white adipocytes. Chronic ABA intake of micrograms per Kg body weight improves blood glucose, lipids, and morphometric parameters (waist circumference and body mass index) in borderline subjects for prediabetes and metabolic syndrome.

This study aimed to investigate β-Caryophyllene (BCA) pharmacokinetics as well as the potential antitumor activity and mechanism of action of BCA and eugenol (EU), alone or in combination, in U87 glioblastoma (GB) cells. The BCA pharmacokinetic was studied by evaluating its concentration profiles in rat blood and cerebrospinal fluid after oral and intravenous administration. EU and BCA antitumor mechanisms were assessed by comparing their effects in U87 GB cells and non-tumoral HMC3 cells.

Introduction: Cancer cachexia (CC) is characterized by weight loss with specifically reduced skeletal muscles and adipose tissues in patients with late-stage cancer. Dihydroartemisinin (DHA), an effective antimalarial derivative of artemisinin, has been demonstrated to have anti-inflammatory and antitumor properties.
Materials And Methods: This study examined the effects of DHA on the Lewis lung carcinoma (LLC)-induced CC mouse model.
