Anti-Hepatoma Activity of a Novel Compound Glaucocalyxin H In Vivo and In Vitro [PDF]

open access: yesAAPS PharmSciTech, 2014
Glaucocalyxin H (GLH) is a new compound isolated from a traditional Chinese medical herb Isodon japonica var. glaucocalyx which has been used for folk medicine. This study was carried out for the first time to investigate the potential role of GLH in anti-hepatoma activity and underlying mechanisms in it.

Glaucocalyxin A, a negative Akt regulator, specifically induces apoptosis in human brain glioblastoma U87MG cells [PDF]

open access: yesActa Biochimica et Biophysica Sinica, 2013
Akt is becoming an attractive target in the development of anti-tumor agents. In the present study, we aimed to discover novel negative Akt regulators against malignant glioma. An Akt regulator screening platform performed in an Akt-GFP overexpression cell line was developed, and natural product library was screened and evaluated using this platform ...

Ellagic acid protects dopamine neurons from rotenone‐induced neurotoxicity via activation of Nrf2 signalling

open access: yesJournal of Cellular and Molecular Medicine, Volume 24, Issue 16, Page 9446-9456, August 2020., 2020
Abstract Parkinson's disease (PD) is the second most prevalent central nervous system (CNS) degenerative disease. Oxidative stress is one of key contributors to PD. Nuclear factor erythroid‐2‐related factor 2 (Nrf2) is considered to be a master regulator of many genes involved in anti‐oxidant stress to attenuate cell death.

Diastereoselective Synthesis of trans-anti-Hydrophenanthrenes via Ti-mediated Radical Cyclization and Total Synthesis of Kamebanin

open access: yes, 2023
Ent-kaurenes consist of an ABC-ring based on a trans-anti-hydrophenanthrene skeleton and a D ring with an exomethylene. Highly oxygen-functionalized ent-kauren-15-ones have promising antiinflammatory pharmacological activity.

Pretreatment of Ascorbic Acid Inhibits MPTP‐Induced Astrocytic Oxidative Stress through Suppressing NF‐κB Signaling

open access: yesNeural Plasticity, Volume 2020, Issue 1, 2020., 2020
Astrocytes are a major constituent of the central nervous system (CNS). Astrocytic oxidative stress contributes to the development of Parkinson’s disease (PD). Maintaining production of antioxidant and detoxification of reactive oxygen and nitrogen species (ROS/RNS) in astrocytes is critical to prevent PD.

Plant-derived natural products as leads to antitumor drugs [PDF]

open access: yes, 2014
Cancer is the main cause of death worldwide. Chemotherapeutic agents used for disease treatments have shown limited antitumor activity, with a high recurrence rate. It has prompted the research efforts to identify anti-tumor compounds.
