Summary
Three compounds from Juniperus oblonga show anti-cancer effects against neuroblastoma (NB) cell lines. These compounds reduced NB cell viability and induced apoptosis, offering potential new treatments for high-risk neuroblastoma.
Area of Science:
- Oncology
- Pharmacology
- Natural Products Chemistry
Background:
- Neuroblastoma (NB) is a common pediatric cancer originating from neural crest cells.
- MYCN amplification is a key indicator of high-risk NB with a poor prognosis.
- Existing treatments for high-risk NB have limitations, necessitating novel therapeutic strategies.
Purpose of the Study:
- To investigate the anti-proliferative and cytotoxic effects of Juniperus oblonga compounds against NB cell lines.
- To evaluate the efficacy of these compounds in NB cells with and without MYCN amplification.
- To assess the safety profile of these compounds in non-cancerous cells.
Main Methods:
- Isolation and identification of three compounds: (-)-deoxypodophyllotoxin (1), (-)-matairesinol (2), and (+)-isocupressic acid (3) from Juniperus oblonga.
- Assessment of anti-proliferative activity against NB cell lines with and without inducible MYCN overexpression.
- Evaluation of apoptosis induction, intracellular calcium levels, and cytotoxicity against HEK-293 cells.
Main Results:
- Compounds 1, 2, and 3 exhibited anti-proliferative activity against NB cell lines.
- Compounds 2 and 3 decreased NB cell viability and induced apoptosis.
- Compound 1 was particularly effective in MYCN-overexpressing NB cells and increased intracellular calcium levels.
- Compounds 1, 2, and 3 showed no significant cytotoxicity against human embryonic kidney cells (HEK-293).
Conclusions:
- Juniperus oblonga compounds demonstrate promising anti-cancer activity against neuroblastoma.
- Compound 1 may possess a distinct mechanism of action in MYCN-amplified NB cells.
- These natural compounds represent potential candidates for developing safer and more effective neuroblastoma therapies, especially for high-risk cases.

Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab...

Subviral agents are infectious entities that resemble viruses but lack one or more viral components, such as a capsid or essential replication machinery. These agents include viroids, prions, and satellites, each possessing distinct structural and functional characteristics that influence their mode of infection and replication.Viroids are the simplest subviral agents, consisting of circular, single-stranded RNA molecules without a protein coat. They exclusively infect plants, relying entirely...

The energy stored by a structure and location of matter in space is called potential energy. For instance, raising a kettlebell changes its spatial location and increases its potential energy. Similarly, a stretched rubber band contains potential energy which, under certain conditions, can be converted into other forms of energy, such as kinetic energy.
Chemical bonds that form attractive forces between atoms also contain potential energy, called chemical energy. When a chemical reaction...

On comparing the reactivity of silver and lead, it is observed that the two ionic species, Ag+ (aq) and Pb2+ (aq), show a difference in their redox reactivity towards copper: the silver ion undergoes spontaneous reduction, while the lead ion does not. This relative redox activity can be easily quantified in electrochemical cells by a property called cell potential. This property is commonly known as cell voltage in electrochemistry, and it is a measure of the energy which accompanies the charge...

Thermodynamics of a Redox Reaction
Thermodynamics is the branch of physics dealing with the relationship between heat and other forms of energy. In an electrochemical cell, chemical energy is converted into electrical energy.
Thus, a link can be predicted between cell potential, free energy change, and the equilibrium constant for the reaction. Cell potential can also be measured as the oxidant or the reducing strength, and similar acid-base strength measures are reflected in equilibrium...
