Abstract:
Research on the aerial parts of Aconitum gymnandrum Maxim. led to identifying three undescribed diterpenoid alkaloids gymnaconitines H-J (1-3), along with eleven known analogues (4-14). Based on 1D/2D NMR and HRESIMS, the structures of these compounds were successfully determined. Additionally, the inhibitory effects of all compounds on NO production were evaluated in lipopolysaccharide-induced RAW264.7 cells. It is noteworthy that compounds 1, 3 and 6 demonstrated significant inhibitory effects, showing IC50 values of 10.36 ± 1.02 μM, 12.87 ± 1.11 μM, and 19.67 ± 1.29 μM, respectively. Using target screening and molecular docking technology, it is hypothesized that compound 1 may play an anti-inflammatory role by combining with Flamin-B.

Centrally Acting Muscle Relaxants: Therapeutic Uses
Centrally acting drugs are classified into spasmolytic and antispasmodic drugs. Spasmolytic drugs such as baclofen, diazepam, and tizanidine inhibit spinal motor neurons and decrease muscle tone. Spasmolytic drugs are administered for severe and chronic spasms due to multiple sclerosis, cerebral palsy, stroke, and spinal cord and muscle injuries. However,...
