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...

Cholinergic Antagonists: Chemistry and Structure-Activity Relationship

Cholinergic Antagonists: Chemistry and Structure-Activity Relationship

Cholinergic antagonists bind to cholinergic receptors and limit the effects of acetylcholine and other cholinergic agonists. Based on the specific cholinergic receptor affinity, these antagonists are classified as muscarinic or nicotinic. Anticholinergics interrupt parasympathetic innervations while sympathetic innervations remain uninterrupted. Muscarinic antagonists are also called 'muscarinic antagonists', 'antimuscarinics', or 'parasympatholytics'. Nicotinic antagonists are called...

Bacterial Phylum Spirochaetes

Bacterial Phylum Spirochaetes

Spirochetes, unique bacteria in the phylum Spirochaetes, are gram-negative, motile, tightly coiled, slender, and flexible. They inhabit aquatic sediments and animals, with some causing diseases like syphilis. Spirochetes are classified into eight genera based on habitat, pathogenicity, phylogeny, and characteristics.Their distinctive motility arises from endoflagella, located within the cell’s periplasm. These endoflagella anchor at the cell poles and extend along the cell length, encased by a...

Other Algae

Other Algae

The group Stramenopiles include some phototrophic microorganisms. Members of this group possess flagella covered in numerous short, hairlike extensions, a feature that inspired the group's name, derived from the Latin words for "straw" and "hair." Some of the main categories of Stramenopiles include diatoms, golden algae, and brown algae.Diatoms are unicellular, photosynthetic eukaryotes, with over 200 known genera. They play a key role in the planktonic communities of both marine and...

Molecules with Multiple Chiral Centers

Molecules with Multiple Chiral Centers

Molecules that possess multiple chiral centers can afford a large number of stereoisomers. For instance, while some molecules like 2-butanol have one chiral center, defined as a tetrahedral carbon atom with four different substituents attached, several molecules like butane-2,3-diol have multiple chiral centers. A simple formula to predict the number of stereoisomers possible for a molecule with n chiral centers is 2n. However, there can be a lower number where some of the stereoisomers are...

Direct-Acting Cholinergic Agonists: Chemistry and Structure-Activity Relationship

Direct-Acting Cholinergic Agonists: Chemistry and Structure-Activity Relationship

Cholinergic agonists or cholinomimetics mimic the action of acetylcholine to stimulate the parasympathetic nervous system. They are categorized into direct-acting and indirect-acting agents. The direct-acting cholinergic drugs induce the parasympathetic response by directly binding to the muscarinic or nicotine receptors. In comparison, the indirect-acting cholinergic drugs prevent acetylcholine hydrolysis, indirectly contributing to the extended parasympathetic response.
The direct-acting...

Background:

Chrysosplenium carnosum is a plant species with potential medicinal properties.
Triterpenoids are a class of natural compounds known for diverse biological activities.
Exploring the chemical constituents of medicinal plants can lead to the discovery of new therapeutic agents.

Purpose of the Study:

To isolate and characterize phytochemicals from the ethanolic extract of Chrysosplenium carnosum.
To evaluate the in vitro anti-tumor activities of isolated compounds against various cancer cell lines.

Main Methods:

Phytochemical analysis using spectroscopic methods (e.g., NMR, MS) for structure elucidation.
In vitro anti-tumor assays on B16F10 (melanoma), SP2/0 (myeloma), and Hep-G2 (hepatocellular carcinoma) cell lines.

Main Results:

Two new oleanane-type triterpenoids (1 and 2) and fourteen known compounds (3-16) were isolated and identified.
Compounds 1, 3, and 4 demonstrated significant inhibitory activity against B16F10 and SP2/0 cell growth.
Moderate cytotoxic activity was observed for compounds 1, 3, and 4 against Hep-G2 cells.
Compound 2 exhibited no significant anti-tumor activity in the tested cell lines.

The ethanolic extract of Chrysosplenium carnosum is a source of novel and known oleanane-type triterpenoids.
Compounds 1, 3, and 4 possess promising anti-tumor potential, particularly against B16F10 and SP2/0 cancer cells.
Further investigation into these compounds may lead to the development of new anti-cancer therapeutics.
