Prenylated xanthones from mangosteen (Garcinia mangostana) target oxidative mitochondrial respiration in cancer cells.

Mangosteen (Garcinia mangostana) is well-known for its nutritional value and health benefits. Breast cancer is the most common cancer and the leading cause of cancer-related mortality among females worldwide. Here we show that the prenylated xanthones, α-mangostin, γ-mangostin, 9-hydroxycalabaxanthone (9-HCX), and garcinone E from the mangosteen pericarp exhibit cytotoxicity against a panel of human cancer cell lines including lung adenocarcinoma (A549), cervical carcinoma (HeLa), prostatic carcinoma (DU 145), pancreatic carcinoma (MIA PaCa-2), hepatocellular carcinoma (Hep G2), bladder urothelial cancer (5637), as well as the triple-negative breast cancer cells MDA-MB-231.

Single-dose comparative pharmacokinetic/pharmacodynamic study of a micellar formulation versus a native Boswellia serrata dry extract in healthy volunteers.

Background: Extracts of oleogum resins of Boswellia trees possess anti-inflammatory activities. Micellar formulations have been developed to increase the oral bioavailability of bioactive boswellic and lupeolic acids.

Purpose: The current single-dose crossover clinical trial compares for the first time pharmacokinetics/pharmacodynamics of two Boswellia serrata nutraceuticals, native Biotikon® BS-85 and micellar Boswellia-Loges®.

The SC cell line as an in vitro model of human monocytes.

In vitro analysis of human macrophages is generally hampered by the necessity to differentiate them from peripheral blood monocytes. We have analyzed to which extent noncancerous SC monocytes could be used as an in vitro macrophage model. Macrophages differentiated from peripheral monocytes using standard CSF1 and CSF2 protocols for M2 and M1 precursors, respectively, were compared with THP-1-derived macrophages treated with PMA and with SC-derived macrophages differentiated either by CSF1, CSF2, or PMA according to different protocols.
