tricyclic

Isolongifolene ((-)-Isolongifolene), a tricyclic sesquiterpene isolated from Murraya koenigii, exhibits antioxidant, anti-inflammatory, anticancer, and neuroprotective properties. It mitigates Rotenone-induced oxidative stress, mitochondrial dysfunction, and apoptosis by modulating the PI3K AKT GSK-3β signaling pathways.

Vancomycin hydrochloride (Vancomycin HCl) is the hydrochloride salt of vancomycin, a branched tricyclic glycosylated peptide with bactericidal activity against most organisms and bacteriostatic effect on enterococci.

Pyrroloquinoline quinone disodium salt (Methoxatin disodium salt), an aromatic tricyclic o-quinone, is a redox cofactor for bacterial dehydrogenases. It is an efficient electron transfer catalyst from a number of organic substrates to molecular oxygen (O2), constructing quinoprotein model reactions.

Triptolide (PG490) belongs to the tricyclic diterpenoid group of natural products and is an inhibitor of NF-κB activation. Triptolide exhibits immunosuppressive, anti-rheumatic, anti-inflammatory, anti-proliferative and anti-tumor activities.

Patchouli alcohol (Patchoulol) is a naturally occurring tricyclic sesquiterpenoid found in patchouli oil. It is a key bioactive component known for its immunomodulatory, anti-inflammatory, antioxidant, antitumor, antibacterial, anti-atherosclerotic, antiemetic, and sedative properties.

Leelamine hydrochloride, a tricyclic diterpene extracted from pine tree bark, inhibits the transcriptional activity of the androgen receptor, known to regulate fatty acid synthesis [2,3]. This compound acts as a cannabinoid receptor type 1 (CB1) agonist and suppresses SREBP1-regulated fatty acid lipid synthesis in prostate cancer cells, irrespective of androgen receptor status.

Cylindrospermopsin, a tricyclic uracil derivative, is a cyanobacterial toxin that was first discovered in an algal bloom contaminating a local drinking supply on Palm Island in Queensland, Australia after an outbreak of a mysterious disease. Cylindrospermopsin targets protein and glutathione synthesis in hepatocytes (IC50s = 1.3 and 2.4 µM, respectively), leading to cell death. [1] It has been shown to inhibit the activity of the uridine monophosphate synthase complex with a Ki value of 10 µM.[2] Cylindrospermopsin is genotoxic, inducing DNA damage as evidenced by double strand breaks and reducing cell viability in HepG2 cells at 0.1-0.5 µg ml.[3]

Wilfordinine D is a natural sesquiterpene alkaloid. The molecule contains a bridged tricyclic structure with four contiguous stereocenters. Its molecular formula is C20H27NO4 and it has a molecular weight of 345.43 g mol.

5-Hydroxy-8-methoxypsoralen (5-Hydroxyxanthotoxin) is a potent tricyclic furocoumarin suicide inhibitor of CYP (cytochrome P-450) and a metabolite of Xanthotoxin. It is used in the treatment of psoriasis, eczema, vitiligo, and certain cutaneous lymphomas in combination with phototherapy involving exposure to sunlight.

β-Patchoulene, a tricyclic sesquiterpene extracted from Pogostemon cablin (patchouli oil), has potential therapeutic applications in the treatment of inflammatory diseases [1].

Stenophyllol B (compound 4), a trimeric stilbene characterized by bicyclic and bridged tricyclic structures, was initially identified in the Dipterocarpaceae family, with occurrences in various species of the genera Hopea, Neobalanocarpus, Shorea, Stemonoporus, and Vateri [1].
