| | FRIEDELIN Usage And Synthesis |
| Uses | Friedelin is a flavonoid extract which displays radical scavenging and anti-typhoid activity. | | Uses | Friedelin can be used as a starting material in the synthesis of:
- Friedel-3-enol acetate, friedel-2-oxo-3-enol acetate, friedel-2-ene derivatives and friedelin ketoxime.
- Oxygenated friedelin derivatives as potent DNA topoisomerase IIα inhibitors.
- Its 1,4-pyrazine derivatives as potent antimicrobial agents.
| | Definition | ChEBI: Friedelin is a pentacyclic triterpenoid that is perhydropicene which is substituted by an oxo group at position 3 and by methyl groups at the 4, 4a, 6b, 8a, 11, 11, 12b, and 14a-positions (the 4R,4aS,6aS,6bR,8aR,12aR,12bS,14aS,14bS-enantiomer). It is the major triterpenoid constituent of cork. It has a role as an anti-inflammatory drug, a non-narcotic analgesic, an antipyretic and a plant metabolite. It is a pentacyclic triterpenoid and a cyclic terpene ketone. | | General Description | Friedelin, a pentacyclic triterpene, is found in several plants like Cissus quadrangularis, Celastrus vulcanicola, Terminalia?avicennioides, and Alangium salvifolium. It is known to act as a histamine H1 receptor?(H1R) antagonist, anti-microbial, anti-HIV, and anti-cancer agent. | | in vivo | Friedelin (40 mg/kg, p.o., single dose) exhibits potent anti-inflammatory activity in the carrageenan (HY-125474)-induced acute inflammation Wistar rat model[2].
Friedelin (30 mg/kg, i.p., once daily, for 14 days) alleviats neuronal dysfunction and memory impairment in the scopolamine (HY-N0296)-induced neurodegeneration mouse model[3].
Friedelin (40 μM, local injection near the right Achilles tendon, once weekly, for 4 weeks) prevents the progression of tendinopathy in the type I collagenase (HY-E70005A)-induced tendinopathy C57BL/6 mouse model[4]. | Animal Model: | Scopolamine (HY-N0296)-induced neurodegeneration mice model[3] | | Dosage: | 30 mg/kg | | Administration: | Intraperitoneal injection (i.p.), once daily, for 14 days | | Result: | Improved scopolamine-induced oxidative stress, neurodegeneration, and memory impairment. |
| Animal Model: | Carrageenan (HY-125474)-induced acute inflammation Wistar rats model[2] | | Dosage: | 40 mg/kg | | Administration: | Oral gavage (p.o.), single dose | | Result: | Maximally inhibited acute inflammatory response, significantly reduced paw edema thickness. |
| Animal Model: | Collagenase Type I (HY-E70005A)-induced tendinopathy C57BL/6 mice model[4] | | Dosage: | 40 μM | | Administration: | Local injection near the right Achilles tendon, once weekly, for 4 weeks | | Result: | Significantly improved tendon mechanical strength, reduced inflammatory cell infiltration, restored ordered collagen fiber arrangement. |
