Physical Properties of Amines

Physical Properties of Amines

Amines with low molecular weight are usually gaseous at room temperature, while those with high molecular weight are liquid or solids in nature. Usually, low molecular weight amines have a rotten fish-like smell. Diamines typically have a pungent smell. For instance, cadaverine and putrescine, depicted in Figure 1, are two molecules responsible for decaying tissue.

Chemotherapy-Induced Nausea and Vomiting: Cannabinoids

Chemotherapy-Induced Nausea and Vomiting: Cannabinoids

Tetrahydrocannabinol (THC) is a phytocannabinoid that primarily interacts with the CB1 receptor, a type of G protein-coupled receptor (GPCR) predominantly in and around the chemoreceptor trigger zone (CTZ) and emetic center. THC also blocks the serotonin receptor activity in the dorsal vagal complex (DVC) by inhibiting serotonin release. THC exerts its anti-emetic effects through these interactions, which are beneficial for patients undergoing chemotherapy.
Two synthetic agonists of THC,...

Antifungal Agents

Antifungal Agents

Amphotericin B is a broad-spectrum antifungal agent that exploits structural differences between fungal and mammalian cell membranes. Its amphipathic structure—featuring a hydrophobic polyene-lactone ring and a hydrophilic region containing mycosamine and carboxylic acid groups—enables selective binding to ergosterol, a sterol predominantly found in fungal plasma membranes. This selective interaction underlies the drug’s antifungal activity, although weak binding to cholesterol contributes to...

Anthelminthic Agents

Anthelminthic Agents

Anthelmintic drugs differ significantly from antiparasitic therapies targeting protozoa, primarily due to differences in parasite biology. Whereas most protozoal treatments act on proliferating cells, anthelmintics are typically directed against mature, nonproliferative helminths. The therapeutic approach considers the helminth's reliance on neuromuscular coordination, glucose metabolism, and microtubular integrity for survival, reproduction, and localization within the host. Most anthelmintics...

Background:

The Patagonian shrub Nardophyllum bryoides is a source of diverse chemical compounds.
Terpenoids are a significant class of natural products with various biological activities.

Purpose of the Study:

To isolate and characterize terpenoids from Nardophyllum bryoides.
To evaluate the cytotoxic potential of isolated compounds against cancer cell lines.
To assess N. bryoides as a sustainable source for bioactive compounds.

Main Methods:

Ethanol extraction of fresh aerial parts of Nardophyllum bryoides.
Isolation and structural elucidation of eleven terpenoids using spectroscopic techniques.
Cytotoxicity assays against a human pancreatic adenocarcinoma cell line.

Main Results:

Eleven terpenoids were identified, including three seco-ent-halimane diterpenoids, two ent-halimanes, and six pentacyclic oleanane and ursane triterpenoids.
Four compounds (2, 6, 8, 11) are novel, and two (1, 4) were previously synthetic.
Compounds 4 and 5 showed activity at micromolar concentrations against pancreatic cancer cells.
Seco-chiliolidic acid (1) was the main component, indicating potential for sustainable sourcing.

Conclusions:

Nardophyllum bryoides is a rich source of diverse terpenoids, including novel structures.
The identified terpenoids possess cytotoxic properties relevant to cancer research.
N. bryoides represents a sustainable natural source for the bioactive compound seco-chiliolidic acid.
