“Pyrrolizidine alkaloids only show toxicity when metabolized in the body and converted to their ‘active form’ containing the pyrrole structure. The active form damages the cancer cell’s ...

Components in mushrooms, such as polysaccharides, pyrrole alkaloids, ergosterols, and unsaturated fatty acids, may contribute to this by affecting the way insulin interacts with glucose in the body.

A new class of metabolite, with a pyrrole-like structure, has been demonstrated in the tissues of animals poisoned by pyrrolizidine alkaloids. There is some correlation between the degree of ...

pyrrole alkaloids, ergosterol, etc., and has been widely served as a functional food for a long time in daily life.[1] TNBC is a subtype of breast cancer that lacks estrogen, progesterone ...

Pyrrole disorder develops when there are too many pyrrole molecules in your body. These can strip your system of essential nutrients that play an important role in mood regulation. Doctors don’t ...

pyrrole alkaloids, ergosterol, etc., and has been widely served as functional foods for a long time in daily life.[1] Pancreatic cancer is one of the most aggressive forms of cancer, with limited ...

Pyrrole is an aromatic organic compound made of carbon, hydrogen and nitrogen atoms. When four pyrrole molecules combine, they form ring-shaped tetrapyrrole macrocycles, which are found in nature ...

In the realm of organic chemistry, one class of compounds has captured the scientific community's attention for decades - alkaloids. These naturally occurring compounds are known for their diverse ...

Dietary supplements that contain ephedra alkaloids (sometimes called ma huang) are widely promoted and used in the United States as a means of losing weight and increasing energy. In the light of ...

New research shows that movement of the ring-like molecule pyrrole over a metal surface runs counter to the centuries-old laws of 'classical' physics that govern our everyday world. Using uniquely ...

Since the early 1800s, practitioners of organic chemistry have been fascinated with a group of plant-derived compounds called "alkaloids." Alkaloids contain at least one nitrogen atom among other ...

A research group at Ehime University has been studying the synthesis and fundamental properties of pyrrole-fused azacoronene (HPHAC), a nitrogen-containing PAH. HPHACs are composed of electron ...
