monoterpenoid

(-)-11,12-Methylenedioxykopsinaline (Compound 4), a monoterpenoid indole alkaloid, has been isolated from Kopsia officinalis [1].

5,22-Dioxokopsane, a monoterpenoid indole alkaloid, is derived from the plant Kopsia officinalis [1].

cis- p- Menthan- 1, 8- diol is a natural menthane monoterpenoid.

(+)-Isopulegol is a monoterpenoid from Mentha canadensis L.

3', 4'-Anhydrovinblastine (3',4'-Anhydrovinblastine) is an antineoplastic agent.

Eucalyptol, a natural monoterpenoid and cyclic ether found in eucalyptus species, effectively controls excessive airway mucus secretion and asthma by inhibiting pro-inflammatory cytokines. It serves as an efficacious treatment for non-purulent sinusitis, reducing inflammation and pain when applied topically, and demonstrating leukemic cell-killing capabilities in vitro.

Benzoylalbiflorin (Paeonivayin) is a monoterpenoid isolated from Radix Paeoniae Alba.

Paeonilactone B ((+)-Paeonilactone B), a monoterpenoid from Paeonilactone, has neuroprotective activity, inhibits oxidative stress, and suppresses H2O2-induced neurotoxicity in rat cortical cells.

4-Isopropylbenzoic acid (Cumic acid) is an aromatic monoterpenoid isolated from the stem bark of Bridelia retusa. 4-Isopropylbenzoic acid shows antifungal activities. 4-Isopropylbenzoic acid is also a reversible and uncompetitive mushroom tyrosinase inhibitor.

(S)-(-)-Citronellal ((S)-(-)-3,7-Dimethyl-6-Octenal) is a monoterpenoid compound

Thymohydroquinone (Thymoquinol) is a monoterpenoid phenolic compound found in thyme, oregano, and other plants in the labiaceae family. Thymohydroquinone inhibits cancer cell growth, reduces oxidative stress and modulates inflammatory responses, scoured 2, 2-diphenyl-1-PicrylHydrazyl radicals in a cell-free assay (IC50 = 2.4 μg ml), In the oxygen radical absorption capacity (ORAC) test at concentrations of 1.6 to 6.4 μg ml, Its Trolox value was 2.6. Thymus hydroquinone inhibited the growth of A2780, OVCAR-8 and CIS-A2780 ovarian cancer cells (IC50 were 3.1, 8.9 and 9.8 μM, respectively) and human ovarian immortalized epithelial cells (IC50 = 14 μM). It also inhibited Plasmodium falciparum in vitro (IC50 = 15.9 μM).

Vinorine is a direct biosynthetic precursor along the complex pathway to the monoterpenoid indole alkaloid ajmaline, an antiarrhythmic drug from the Indian medicinal plant Rauvolfia serpentina.

(+)-Fenchol, a monoterpenoid discovered in various plants including Cannabis, serves both as a precursor in synthesizing other terpenoids and as a chiral building block for the organic synthesis of numerous compounds. Additionally, formulations incorporating (+)-fenchol are employed as fragrance ingredients.

(-)-Fenchone is a bicyclic monoterpenoid widely distributed in plants and can be extracted from Foeniculum vulgare and Peumus boldus. (-)-Fenchone has a wide range of biological activities including antioxidant, wound healing, antidiarrheal, antifungal, anti-injury sensory and bronchodilator activities. (-)-Fenchone is a potential anti-tumor compound.
