Paullinia pinnata L. (Sapindaceae) is an endemic West African plant that is extensively used in traditional medicine to treat various diseases. Previous phytochemical analysis by various groups led to the isolation of several novel lupene-based triterpenene derivatives along with other classes of compounds. As part of our continued phytochemical studies on the roots of this plant, we have now identified yet another novel triterpene, 6a-(3'-methoxy-4'-hydroxybenzoyl)-lup-20(29)-ene-3-one. The identification of the compound through comprehensive spectroscopic studies is discussed.

Article Synopsis
- Colorectal cancer (CRC) is a major cause of cancer deaths, and oxaliplatin (OXA) is a primary treatment that faces challenges due to the tumor microenvironment (TME).
- A new multifunctional nanosystem, Rg3-Lip-OXA/CaO, uses Ginsenoside Rg3 liposomes to target CRC cells, delivering OXA and calcium peroxide (CaO) together.
- Research showed that this nanosystem had good stability and release properties, effectively targeted cancer cells, and significantly suppressed tumor growth in mice, while also showing manageable acute toxicity.

Maturation inhibitors (MIs) block HIV-1 maturation by preventing the cleavage of the capsid protein and spacer peptide 1 (CA-SP1). Bevirimat (BVM), a first-in-class MI, displayed sub-optimal efficacy in clinical trials due to presence of SP1:V7A polymorphism in the Gag protein.This polymorphism is inherently present in HIV-1 subtype C and conferred resistance to BVM.

Context: The decline in ovarian reserve is a major concern in female reproductive health, often associated with oxidative stress and mitochondrial dysfunction. Although ginsenoside Rg1 is known to modulate mitophagy, its effectiveness in mitigating ovarian reserve decline remains unclear.
Objective: To investigate the role of ginsenoside Rg1 in promoting mitophagy to preserve ovarian reserve.

Over-accumulation of reactive oxygen species (ROS) causes hepatocyte dysfunction and apoptosis that might lead to the progression of liver damage. Sirtuin-3 (SIRT3), the main NAD+-dependent deacetylase located in mitochondria, has a critical role in regulation of mitochondrial function and ROS production as well as in the mitochondrial antioxidant mechanism. This study explores the roles of astragaloside IV (AST-IV) and formononetin (FMR) in connection with SIRT3 for potential antioxidative effects.
