Notorious Fungus Blamed for ‘Mummy’s Curse’ Is Now a Promising Cancer Treatment

In the 1920s, several workers of the excavating party that exposed the tomb of King Tutankhamun and faced premature death. Five decades later, 10 out of 12 scientists died after entering Mausoleum The 15th century Polish King Casimir IV’sThe In both cases the researchers suggested that the spots of the fungus could play a Composition In the mysterious death, especially Identification Fungus Espergilus flavus In the burial of polish.

A. Flavus Returning now, but not as a re-awakened killer from ancient tombs, instead as amazingly effective cancer-loving compounds. Researchers created a compound by correcting a new marked molecules found in the fungus that effectively perform against leukemia cells as an FDA-affected drug.

This is the center of the anti-cancer features, which are known as ribosomali synthesized and translated peptides, or RipsA variety of natural molecules combined by ribosomes (which produces protein) and later vary by enzymes. They conduct various biological activities, some of which are already known for their anti -cancer PropertyThe

To today, researchers have identified only a few handful of reps in the fungus – which is significantly lower than thousands of thousands of bacteria previously discovered in the bacteria. A part of the problem is that scientists did not fully understand how the fungus made the Rips.

“The synthesis of these compounds is complicated,” a postdotcoal fellow at the University of Pennsylvania’s Chemical and Biomolicular Engineering at the University of Pennsylvania. StatementThe “But this is what gives them this extraordinary organic functionality.”

Genetic analysis is a specified proposed A. Flavus Protein can be a source of fungi rips. Certainly, when NIE and its colleagues have shut down the genes responsible for protein, the chemical markers of the Rips also disappeared. By using this method, the team has discovered four separate A. Flavus Reps with unregistered structures before the interlocking rings. Researchers after the purification of these rips, which they named asparigimycin, performed well without changing the cells against the leukemia cells of four unique molecules.

When a lipid (a fatty molecule) is mixed with, a separate rip Along with variants, sitbravine and dononorubisin are both long-founded FDA-approved leukemia drugs. To investigate the features of this lipid enhancement, the researchers returned to the genes. In this way, they identified a gene associated with the process that gives enough asperigimycins to cancer cells.

“This gene acts like a gateway,” says the first author of the study published on Monday Chemical biologyThe “It not only helps aspargimikins entering cells, it can enable other ‘psychlic peptides’ to do the same.” Chakric peptides are other chemicals that are known as familiar Medic. “This gene gives us another tool for the development of our drugs knowing how chemicals transport it into cells.”

Researchers have also discovered that asparigimikins can disrupt cell division – which is good news for cancer treatment, since the cancer is composed of uncontrolled cell division. Furthermore, the compounds did not have little effect on the cells of the breast, liver or lung cancer, as well as several bacteria and fungi. Although it may sound like a negative thing, the possible target effects of asparigimesins can be an important feature for future drugs. Going forward, researchers noticed to test asperigimikins in animal tests.

Recent research investigated a committed new cancer therapy, but it also paved the way for future research in fungi drugs.
