monoterpenoid

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

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.

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

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.

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).

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

(-)-trans-Myrtanol is an antimicrobial and acaricidal monoterpenoid compound that demonstrates potent inhibitory activity against harmful intestinal bacteria. It also exhibits strong acaricidal effects against Dermatophagoides farinae, D. pteronyssinus, and Tyrophagus putrescentiae, with reported LD50 values of 2.30 µg/cm², 2.22 µg/cm², and 12.95 µg/cm², respectively. These properties highlight its potential utility in studies of microbial control, mite management, and natural-product-based bioactive agents.

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

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

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

(-)-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.

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

(-)-Myrtenol ((1R)-(-)-Myrtenol) is a naturally occurring plant-derived monoterpenoid with anxiolytic, gastric cytoprotective, and wound-healing activities, and can be used in the study of gastric ulcers.

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.

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

(+)-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.
