iChip

iChip

The cultivation of environmental microorganisms has long been hindered by the inability to replicate complex native conditions in vitro. The isolation chip (iChip) addresses this limitation by facilitating the growth of previously uncultivable microorganisms through in situ incubation. Designed for high-throughput microbial cultivation, the iChip comprises hundreds of microchambers, each capable of housing a single microbial cell. These microchambers are loaded with a mixture of molten agar and...

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

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

Indirect-acting cholinergic agonists are agents that interact with the acetylcholinesterase enzyme in the synaptic cleft, preventing the breakdown of acetylcholine into choline and acetate. Consequently, the concentration of acetylcholine in the synaptic cleft increases. These agonists can be classified into reversible and irreversible inhibitors based on their duration of action.
Reversible inhibitors display short to medium durations of action. Short-acting agents include simple alcohols with...

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...

Chirality in Nature

Chirality in Nature

Chirality is the most intriguing yet essential facet of nature, governing life’s biochemical processes and precision. It can be observed from a snail shell pattern in a macroscopic world to an amino acid, the minutest building block of life. Most of the snails around the world have right-coiled shells because of the intrinsic chirality in their genes. All the amino acids present in the human body exist in an enantiomerically pure state, except for glycine - the sole achiral amino acid. The...

Area of Science:

Phytochemistry
Pharmacology

Background:

Michelia champaca L. is a plant species known for its traditional medicinal uses.
The chemical constituents of M. champaca L. have not been fully elucidated.
Natural products are a rich source of potential therapeutic agents.

Purpose of the Study:

To isolate and identify chemical compounds from the branches of Michelia champaca L.
To evaluate the in vitro cytotoxic activity of selected isolated compounds against human cancer cell lines.

Main Methods:

Phytochemical analysis involving isolation and structural elucidation of compounds from M. champaca L. extracts.
Cell proliferation assays were conducted using human breast and lung cancer cell lines.
Quantitative assessment of cell viability and proliferation inhibition.

Main Results:

Seventeen compounds were successfully isolated and identified, including alkaloids, lignans, and other phenolic compounds.
Liriodenine (7) exhibited the most significant inhibitory effect on the proliferation of both breast and lung cancer cells among the tested compounds.
Other tested compounds also showed varying degrees of antiproliferative activity.

Conclusions:

Michelia champaca L. is a valuable source of diverse bioactive phytochemicals.
Liriodenine is a promising lead compound for further investigation in the development of novel anticancer therapeutics.
The findings support the ethnobotanical use of M. champaca L. and warrant further preclinical studies.
