| FooDB Name | Flavones |
|---|
| Description | Flavone, also known as 2-phenylchromone, belongs to the class of organic compounds known as flavones. These are flavonoids with a structure based on the backbone of 2-phenylchromen-4-one (2-phenyl-1-benzopyran-4-one). Thus, flavone is considered to be a flavonoid. Flavone is a bitter tasting compound. Flavone has been detected, but not quantified in, several different foods, such as dills (Anethum graveolens), feijoas (Feijoa sellowiana), pomegranates (Punica granatum), and rosemaries (Rosmarinus officinalis). This could make flavone a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on Flavone. |

Therapeutically, it is used to prevent aflatoxin poisoning, commonly in food safety and liver protection applications, and may have potential in cancer prevention and treatment. | DUKE | | Anti-aggregant | | An agent that prevents platelet aggregation, reducing blood clot formation. Its biological role is to inhibit platelet activation, and its therapeutic applications include preventing thrombosis and stroke. Key medical uses include treating cardiovascular diseases, such as myocardial infarction and atrial fibrillation, and managing conditions that increase the risk of blood clots. | DUKE | | Anti bacterial | 33282 | An agent that inhibits the growth of or destroys bacteria, playing a crucial role in preventing and treating infections. Therapeutically, it is used to combat bacterial infections, with key medical applications including treating pneumonia, tuberculosis, and skin infections, as well as preventing surgical site infections and sepsis. | DUKE | | Anti-escherichic | | An antibody binding to Escherichia-specific targets, playing a role in immune defense. Therapeutically, it is used to combat E. coli infections, with key medical applications in treating urinary tract infections, sepsis, and gastrointestinal diseases. | DUKE | | Anti estrogenic | 35222 | An agent that blocks or reduces estrogen's effects, used to treat hormone-sensitive cancers, such as breast cancer, and manage conditions like endometriosis and uterine fibroids, by inhibiting estrogen's biological role in promoting cell growth. | DUKE | | Anti histaminic | 37956 | An agent that blocks histamine receptors, reducing allergic symptoms. Therapeutically, it alleviates itching, sneezing, and runny nose, commonly used in managing allergies, itching, and hives, as well as treating conditions like anaphylaxis and allergic rhinitis. | DUKE | | Anti leukemic | 35610 | An agent that targets and inhibits the growth of leukemia cells, playing a crucial role in cancer treatment. Therapeutically, it is used to induce remission, manage symptoms, and improve survival rates in patients with leukemia. Key medical uses include treating acute and chronic leukemia, lymphoma, and other hematological malignancies. | DUKE | | Anti-mutagenic | | An agent that interferes with the mutagenicity of a substance, preventing DNA damage and mutations. Its biological role is to protect cells from genetic alterations, and it has therapeutic applications in cancer prevention and treatment, as well as key medical uses in reducing the risk of genetic disorders and birth defects. | DUKE | | Anti proliferant | | An agent that prevents or inhibits cell growth and division, used therapeutically to treat cancer, manage tumor growth, and prevent restenosis after angioplasty, reducing abnormal cell proliferation. | DUKE | | Anti-staphylococcic | 33282 | An agent that combats Staphylococcus infections, playing a crucial role in preventing bacterial growth. Therapeutically, it is used to treat skin and soft tissue infections, respiratory tract infections, and bloodstream infections. Key medical uses include treating methicillin-resistant Staphylococcus aureus (MRSA) and other staphylococcal infections, reducing the risk of infection and promoting wound healing. | DUKE | | Anxiolytic | 35474 | An agent that reduces anxiety symptoms, commonly used in managing anxiety disorders, such as generalized anxiety disorder and panic disorder, by modulating neurotransmitters like GABA, promoting relaxation and calming effects. | DUKE | | Bacteristat | 33282 | An agent that inhibits bacterial growth, reducing the proliferation of microorganisms without killing them. Therapeutically, bacteristats are used to treat infections, preventing the spread of bacteria and allowing the host's immune system to clear the infection. Key medical uses include treating urinary tract infections, acne, and other bacterial infections where bactericidal agents may not be necessary. | DUKE | | Cyclooxygenase inhibitor | 35544 | An agent that blocks the activity of cyclooxygenase enzymes, reducing inflammation and pain. Therapeutically, it is used to treat conditions such as arthritis, headaches, and menstrual cramps, by decreasing prostaglandin production, a key mediator of inflammation. | DUKE | | Cytotoxic | 52209 | An agent that kills or damages cells, playing a biological role in immune responses and therapeutic applications in cancer treatment. Key medical uses include chemotherapy, targeting and destroying cancer cells, and treating certain autoimmune diseases by eliminating harmful cells. | DUKE | | Estrogenic | | An agent that mimics the effects of estrogen, regulating female reproductive processes and development. Therapeutically, estrogenic agents are used in hormone replacement therapy, contraception, and treating menopausal symptoms, as well as certain cases of osteoporosis and infertility. | DUKE | | Fungicide | 24127 | An agent that kills or inhibits the growth of fungi, playing a biological role in preventing fungal infections. Therapeutically, it is used to treat fungal diseases, with key medical applications including athlete's foot, ringworm, and candidiasis, as well as agricultural uses to protect crops from fungal damage. | DUKE | | Hepatoprotective | 62868 | An agent that protects the liver from damage, promoting liver health and function.
