Antidiarrheal activities of Isovanillin, iso-acetovanillon and Pycnocycla spinosa Decne ex.Boiss extract in mice
Res Pharm Sci 2014 Mar-Apr;9(2):83-9.PMID:25657776doi
Isovanillin and iso-acetovanillon are two phenolic components isolated from a number of plants including Pycnocycla spinosa. P. spinosa extract has antispasmodic and antidiarrheal activities. However, no comparative study has been done on antidiarrheal action of Isovanillin and iso- acetovanillon, so far. The aim of this study was to investigate antidiarrheal action of Isovanillin and iso-acetovanillon and their effects on small intestinal transit, for comparison with propantheline. Male mice (25-30 g), fasted over night with free access to water, were treated with test compounds or control (p.o.). Thirty min later castor oil (0.5 ml) was given orally to the animals. In another groups of animals MgSO4 (0.5 ml of 10% solution) was given first and half an hour later the test drugs were administered. Onset and number of wet defecations were recorded for each animal over 3.5 h after treatment with diarrhoea inducing agents. In another groups, intestinal transit of charcoal meal was determined following administration of the compounds. Isovanillin (2 mg/kg & 5 mg/kg), iso-acetovanillon (2 mg/kg & 5 mg/kg) and P. spinosa extract (5 mg/kg) delayed onset of diarrhoea and significantly reduced wet defecation induced by castor oil and MgSO4. They all had antidiarrheal effect similar to propantheline (5 mg/kg). Isovanillin, iso-acetovanillon and P. spinosa extract compared to control groups, significantly reduced small intestinal transit of charcoal meal. This study shows that antidiarrheal effect of P. spinosa extract is at least partially due to presence of two active compounds Isovanillin and iso-acetovanillon.
Antispasmodic activity of Isovanillin and isoacetovanillon in comparison with Pycnocycla spinosa Decne.exBoiss extract on rat ileum
Res Pharm Sci 2014 May-Jun;9(3):187-92.PMID:25657788doi
Isovanillin and isoacetovanillon are two components found in P. spinosa Decne.exBoiss extract with no previously reported effect on ileum contractions. Spasmolytic effect of Isovanillin and isoacetovanillon were examined on response to electrical field stimulation (EFS), acetylcholine (ACh) and 5-HT in strips of rat ileum. Longitudinal ileum strips were set up in an organ bath containing oxygenated Tyrode's solution. All strips that was contracted in response to EFS, acetylcholine or 5-HT showed relaxation in the presence of Isovanillin (5-320 μg/ml), or isoacetovanillon (5-320 μg/ml). Isovanillin and isoacetovanillon inhibited the response to 5-HT with IC50 values of 356±50μM and 622±110μM respectively. They reduced the response to EFS without significantly affecting the acetylcholine response. P. spinosa extract (5-160 μg/ml) in a concentration dependent manner reduced the response to 5-HT, acetylcholine and EFS. This study demonstrated that Isovanillin and isoacetovanillon are relaxant of ileum contractions induced by 5-HT and EFS and they have contribution to the relaxant effect of P. spinosa extract but other components are responsible for the inhibition of acetylcholine by the extract.
Isovanillin derived N-(un)substituted hydroxylamines possessing an ortho-allylic group: valuable precursors to bioactive N-heterocycles
Org Biomol Chem 2014 Apr 28;12(16):2552-8.PMID:24576957DOI:10.1039/c3ob42460j.
The intramolecular 1,3-dipolar cycloaddition of Isovanillin derived N-aryl hydroxylamines possessing ortho-allylic dipolarophiles affords novel benzo analogues of tricyclic isoxazolidines that can be readily transformed into functionalized lactams, γ-aminoalcohols and oxazepines. The corresponding N-unsubstituted hydroxylamines give rise to tetrahydroisoquinolines. Anxiogenic properties of these compounds are tested in zebra fish.
Radioiodination, nasal nanoformulation and preliminary evaluation of Isovanillin: A new potential brain cancer-targeting agent
Appl Radiat Isot 2022 Nov;189:110464.PMID:36150311DOI:10.1016/j.apradiso.2022.110464.
Brain cancer is a challenging disease to treat using conventional approaches. The present investigation aimed to develop a radiopharmaceutical targeting brain cancer based on natural Isovanillin. Different parameters were optimized, resulting in high radiolabeling efficiency (97.3 ± 1.2%) and good stability (<48 h). The tracer was formulated for intranasal delivery in a chitosan nanoparticles system with a mean particle size of 141 ± 2 nm, a polydispersity index of 0.23 ± 0.02, and a zeta potential of -17.4 ± 0.3 mV to enhance nasal uptake and surmount the blood-brain barrier. The system was characterized and assessed in-vitro for suitability and specificity and evaluated in-vivo in normal and tumorized mice. The biodistribution profile in brain tumor showed 20.5 ± 0.4 %ID/g localization and cancer cell targeting within 60 min. Improvement in brain tumor uptake resulted from both the nanoformulation and nasal administration of iodoisovanillin. Overall, the reported results encourage the potential use of the nanoformulated labeled compound as an anticancer agent.
Metabolism of Isovanillin by aldehyde oxidase, xanthine oxidase, aldehyde dehydrogenase and liver slices
Pharmacology 2005 Mar;73(4):199-208.PMID:15627845DOI:10.1159/000082860.
Aromatic aldehydes are good substrates of aldehyde dehydrogenase activity but are relatively poor substrates of aldehyde oxidase and xanthine oxidase. However, the oxidation of xenobiotic-derived aromatic aldehydes by the latter enzymes has not been studied to any great extent. The present investigation compares the relative contribution of aldehyde dehydrogenase, aldehyde oxidase and xanthine oxidase activities in the oxidation of Isovanillin in separate preparations and also in freshly prepared and cryopreserved liver slices. The oxidation of Isovanillin was also examined in the presence of specific inhibitors of each oxidizing enzyme. Minimal transformation of Isovanillin to isovanillic acid was observed in partially purified aldehyde oxidase, which is thought to be due to residual xanthine oxidase activity. Isovanillin was rapidly metabolized to isovanillic acid by high amounts of purified xanthine oxidase, but only low amounts are present in guinea pig liver fraction. Thus the contribution of xanthine oxidase to Isovanillin oxidation in guinea pig is very low. In contrast, Isovanillin was rapidly catalyzed to isovanillic acid by guinea pig liver aldehyde dehydrogenase activity. The inhibitor studies revealed that Isovanillin was predominantly metabolized by aldehyde dehydrogenase activity. The oxidation of xenobiotic-derived aromatic aldehydes with freshly prepared or cryopreserved liver slices has not been previously reported. In freshly prepared liver slices, Isovanillin was rapidly converted to isovanillic acid, whereas the conversion was very slow in cryopreserved liver slices due to low aldehyde dehydrogenase activity. The formation of isovanillic acid was not altered by allopurinol, but considerably inhibited by disulfiram. It is therefore concluded that Isovanillin is predominantly metabolized by aldehyde dehydrogenase activity, with minimal contribution from either aldehyde oxidase or xanthine oxidase.
