Crab vs. Mushroom: A Review of Crustacean and Fungal Chitin in Wound Treatment

mycolabadmin

Chitin, a natural material found in crab shells and mushrooms, can be used to make wound dressings that speed up healing and fight infection. The review compares these two sources, finding that crab-derived chitin has been studied more extensively and has several commercial products available, while mushroom-derived chitin offers advantages like lower cost and easier processing. Both types work by promoting cell growth, stopping bleeding, and killing bacteria, making them promising alternatives to traditional wound dressings for treating difficult-to-heal wounds.

Diversity and bioprospecting activities of endophytic Fungi associated with different Egyptian medicinal plants

mycolabadmin

Scientists studied fungi that live inside Egyptian medicinal plants and found that one type called Aspergillus terreus produces compounds with powerful healing properties. These compounds can fight harmful bacteria, reduce oxidative damage, and even kill cancer cells while being safe for normal cells. This discovery suggests that fungi living in medicinal plants could be valuable sources of new medicines, offering hope for developing new treatments for infections and cancer.

Fungal-fungal cocultivation alters secondary metabolites of marine fungi mediated by reactive oxygen species (ROS)

mycolabadmin

Researchers discovered that when two types of ocean fungi grow together, one of them produces a protective chemical called alternariol that can kill bacteria and cancer cells. This happens because the fungi recognize each other as competitors and trigger special stress signals that activate defensive chemical production. Interestingly, fungi from the ocean respond differently than those from land, suggesting they have evolved unique survival strategies for harsh marine environments.

Biodiversity-Driven Natural Products and Bioactive Metabolites

mycolabadmin

This comprehensive review explores how diverse organisms like plants, fungi, and marine creatures produce remarkable chemical compounds for survival and defense. These natural products have inspired many modern medicines, but scientists now understand that the chemical diversity comes not just from the organisms themselves but from their ecological interactions and environmental challenges. By studying how these chemicals are made and what triggers their production, researchers can discover new drugs and medicines while protecting the ecosystems that generate them.

Chitosan and Chitooligosaccharide: The Promising Non-Plant-Derived Prebiotics with Multiple Biological Activities

mycolabadmin

Chitosan and chitooligosaccharide are natural compounds derived from crustacean shells and fungi that act as prebiotics to improve gut health. These compounds can fight bacteria and viruses, reduce inflammation, protect against oxidative stress, and help maintain healthy weight and blood sugar levels. They represent a promising, biodegradable alternative to synthetic pharmaceuticals with multiple health benefits.

In silico screening and molecular dynamics analysis of natural DHPS enzyme inhibitors targeting Acinetobacter baumannii

mycolabadmin

Researchers used computer modeling to find natural compounds from plants and mushrooms that can inhibit a key bacterial enzyme (DHPS) in dangerous antibiotic-resistant bacteria called Acinetobacter baumannii. They tested thousands of natural molecules and identified two promising candidates that bind strongly to this enzyme and prevent bacteria from producing folic acid, which they need to survive. The study suggests these natural compounds could potentially be developed into new antibiotics to fight infections caused by drug-resistant bacteria.

Encapsulation of progesterone in reishi mushroom composite for optimized hormone replacement and targeted anticancer therapy

mycolabadmin

Researchers created a new treatment by combining progesterone (a hormone) with reishi mushroom powder to make it work better in the body. The mushroom acts like a protective wrapper that slowly releases the hormone, making it more effective for treating menopausal symptoms and fighting breast cancer cells. The combination also fights harmful bacteria and fungi while remaining stable during storage. This approach combines traditional medicine with modern pharmaceutical science.

Glucose-6-Phosphate Dehydrogenase Modulates Shiraia Hypocrellin A Biosynthesis Through ROS/NO Signaling in Response to Bamboo Polysaccharide Elicitation

mycolabadmin

Researchers discovered that a specific enzyme called glucose-6-phosphate dehydrogenase (G6PDH) controls the production of hypocrellin A, a powerful therapeutic compound found in Shiraia fungi. When bamboo polysaccharides are added to fungal cultures, they trigger G6PDH activity, which then increases the production of signaling molecules that boost hypocrellin A biosynthesis. This finding could lead to better ways to produce this promising cancer-fighting photosensitizer at industrial scales using simple, cost-effective methods.

Genome-Mining Based Discovery of Pyrrolomycin K and L from the Termite-Associated Micromonospora sp. RB23

mycolabadmin

Researchers discovered two new antimicrobial compounds called pyrrolomycins from a bacterium found in termite guts using genome analysis and advanced chemistry techniques. These compounds are modified versions of known antimicrobial molecules, featuring halogenated structures. Interestingly, the bacteria appears to protect itself from its own toxic compounds through chemical modifications, a strategy that researchers believe could inform the design of new antibiotics to combat drug-resistant bacteria.
