Three new compounds and three known sesquiterpenoids were isolated from Nardostachys jatamansi roots. Compounds 1, 2, and 6 showed neuroprotective effects against glutamate-induced neurotoxicity in neuronal cells.
Area of Science:
- Natural Product Chemistry
- Pharmacology
- Neuroscience
Background:
- Nardostachys jatamansi is a medicinal plant with a history of traditional use.
- Sesquiterpenoids are a class of natural products with diverse biological activities.
- Neurodegenerative diseases pose a significant global health challenge.
Purpose of the Study:
- To isolate and characterize chemical constituents from Nardostachys jatamansi roots.
- To evaluate the neuroprotective potential of isolated compounds.
Main Methods:
- Isolation of compounds using chromatographic techniques.
- Structure elucidation using comprehensive spectroscopic methods (MS, IR, NMR).
- Assessment of neuroprotection against glutamate-induced cytotoxicity in SH-SY5Y cells.
Main Results:
- Three new compounds ((8S)-neonardochinone B, 4-methylocta-2,4,6-trienedioic acid, narchinol D) and three known sesquiterpenoids (kanshones A, K, L) were identified.
- Compounds 1, 2, and 6 exhibited significant neuroprotective effects at 10 µM.
- Glutamate-induced cytotoxicity in SH-SY5Y neuronal cells was counteracted by these compounds.
Conclusions:
- Nardostachys jatamansi is a source of novel sesquiterpenoids with potential therapeutic applications.
- Compounds 1, 2, and 6 show promise as neuroprotective agents.
- Further investigation into the mechanisms of action is warranted.

Nomenclature of Aromatic Compounds with a Single Substituent
Nomenclature of Aromatic Compounds with Multiple Substituents
For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...

Organic nitrates, such as nitroglycerin, play a pivotal role. Once metabolized, they liberate nitric oxide, a molecular marvel. Nitric oxide triggers guanylyl cyclase and augments cGMP production. This biochemical cascade orchestrates the relaxation of vascular smooth muscles, ushering in vasodilation and enhancing coronary blood flow. Administered...
