| Description: |
3,4-Oxo- isopropylidene-shikimic acid has significant anti-inflammatory, anti-thrombosis, antioxidant, analgesic effects, it has protective effects on experimental colitis induced by trinitrobenzenesulfonic acid in rats, probably due to an antioxidant action. 3,4-Oxo-isopropylidene shikimic acid relieves the brain edema of rats subjected to MCAT by improving the energy metabolism and Na +, K +-ATPase activity in rat brain tissue. 3,4-Oxo-isopropylidene-shikimic acid has exhibited ameliorative effect on cognitive impairment in experimental animal models of dementia, it can promote adipogenesis by up-regulating expressions of C/EBP β, PPAR γ, C/EBP α, aP2 and FAS, and also stimulate adipokines during adipocyte differentiation, suggests that stimulation of adipokines and cognitive enhancing effect of 3,4-oxo-isopropylidene-shikimic acid have some relationship.

METHODS AND RESULTS:
3,4-O-Isopropylidene shikimic acid (ISA,1-100 micromol/L) effectively reduced PMN adhesion to TNF-alpha-induced HUVEC with the inhibitory rate from 17.2 % to 53.5 %, and exerted no effect on PMN adhesion to normal HUVEC. Adhesion molecule ICAM-1 surface protein and mRNA expression induced by TNF-alpha (400 kU/L) were significantly inhibited by ISA. In addition, the cell viability of HUVEC was unchanged 48 h after treatment with ISA.
CONCLUSIONS:
ISA inhibited TNF-alpha-stimulated PMN-HUVEC adhesion and expression of ICAM-1. | | Journal of Traditional Chinese Medical Sciences, 2014,1(2):120-5. | | 3,4-Oxo-isopropylidene-shikimic acid promotes adiopkine expression during murine 3T3-L1 fibroblast differentiation into adipocytes[Reference: WebLink] |
3,4-O-Isopropylidene shikimic acid (ISA), a derivative of shikimic acid, has exhibited ameliorative effect on cognitive impairment in experimental animal models of dementia.
METHODS AND RESULTS:
This study investigated the effect of ISA on lipid accumulation and adipokine secretion during differentiation of 3T3-L1 fibroblasts to adipocytes.ISA promoted 3T3-L1 fibroblast differentiation to adipocytes and increased triglyceride content by 26%. On mechanistic levels, ISA increased expressions of C/EBP β, PPAR γ, C/EBP α, aP2 and FAS. Moreover, ISA stimulated expressions of adipokines secreted by adipocytes, including adiponectin, leptin, and resistin.
CONCLUSIONS:
These findings demonstrated that ISA promoted adipogenesis by up-regulating expressions of C/EBP β, PPAR γ, C/EBP α, aP2 and FAS, and also stimulated adipokines during adipocyte differentiation. Further study should clarify the relationship between stimulation of adipokines and cognitive enhancing effect of ISA. |

METHODS AND RESULTS:
Arteriovenous shunt model was adopted to measure thrombus weight; The neurologic deficit (ND) and the infarct size (IS) of the middle cerebral thrombosis (MCAT) model induced by FeCl3 were observed; The effect of ISA on platelet aggregation rate of rat and rabbit by giving ISA in vivo and in vitro was studied.
ISA 25, 50, 100 and 200 mg.kg-1 ig was shown to reduced the weight of thrombus in arteriovenous shunt model; ISA 50, 100 and 200 mg.kg-1 ig for 2 times in 24 hours, attenuated the ND of rats subjected to MCAT; ISA 100 and 200 mg.kg-1 reduced IS of rats after MCAT by 27.8% and 31.6%, respectively; ISA 50, 100 and 200 mg.kg-1 ig inhibited platelet aggregation of normal rats; ISA 10(-3)-10(-5) mol.L-1, inhibited rabbit platelet aggregation in vitro.
CONCLUSIONS:
ISA inhibited thrombosis by anti-platelet-aggregation. | | Dig. Dis.

SA is extracted from Illicium verum Hook.fil., which has been used in traditional Chinese medicine and used for treating vomiting, stomach aches, insomnia, skin inflammation, and rheumatic pain.
METHODS AND RESULTS:
To investigate the effects and the protective mechanism of 3,4-oxo-isopropylidene-shikimic acid on experimental colitis model induced by 2,4,6-trinitrobenzenesulfonic acid (TNBS) in rats.ISA significantly ameliorated macroscopic damage, reduced colon weight/length ratios and the activity of MPO, depressed MDA and NO levels and iNOS activity, and enhanced GSH level, and GSH-Px and SOD activities in the colon tissues of experimental colitis in a dose-dependent manner. Moreover, the effect of ISA (200 mg/kg) was as effective as sulfasalazine (500 mg/kg).
CONCLUSIONS:
The findings of this study demonstrate the protective effect of ISA on experimental colitis, probably due to an antioxidant action. |
