Synthesis, thymidine phosphorylase, angiogenic inhibition and molecular docking study of isoquinoline derivatives

Isoquinoline analogues (KA-1 to 16) have been synthesized and evaluated for their E. coli thymidine phosphorylase inhibitory activity. Except compound 11, all other analogs showed outstanding thymidine inhibitory potential ranging in between 4.40 +/- 0.20 to 69.30 +/- 1.80 mu M when compared with standard drug 7-Deazaxanthine (IC50 = 38.68 +/- 4.42 mu M). Structure Activity Relationships has been established for all compounds, mainly based on substitution pattern on phenyl ring. All analogs were characterized by various spectroscopic techniques such as H-1 NMR, C-13 NMR and EI-MS. The binding interactions of isoquinoline analogues with the active site of TP enzyme, the molecular docking studies were performed. Furthermore, the angiogenic inhibitory potentials of isoquinoline analogues (KA-1-9, 14, 12 and 16) were determined in the presence of standard drug Dexamethasone based on percentage inhibitions at various concentrations. Herein this work analogue KA-12, 14 and 16 emerged with most potent angiogenic inhibitory potentials among the synthesized analogues.

A New 1,5-Dihydroxy-4-methoxyisoquinoline from Scolopendra subspinipes mutilans

A new isoquinoline, 1,5-dihydroxy-4-methoxyisoquinoline (1), was obtained from Scolopendra subspinipes mutilans. Compound 1 showed moderate cytotoxicity on tumour cells with IC50 values ranging from 13 to 26 mu M against five esophageal squamous cancer cells whereas low cytotoxicity against normal human esophageal epithelial cells. Isoquinoline ring oxidized at C(1), C(4), and C(5) can enhance its cytotoxicity. In addition, compound 1 showed potent inhibitory effect (inhibition rate > 50% at 13 mu M) on cell migration in human umbilical vein endothelial cells. This article mainly studies the structure and activity of 1, and more modification of 1 as a potential anticancer agent.

Synthesis of Isoquinoline from Benzimidates via Ru(II)-Catalyzed C-H Alkylation/Annulations with Diazo Compounds

A Ru(II)-catalyzed C-H alkylation/annulations of benzimidate with diazo compounds have been developed for the synthesis of functionalized isoquinoline. The reaction proceeds under mild condition and exhibit broad functional group tolerance. This strategy also provides a direct approach to isoquinolines and 3,4-dihydrophenanthridin synthesis. Moreover, Ru(II)-catalyzed C-H carbenoid functionalization of benzimidate with diazodiester is also demonstrated.

Preparative separation of isoquinoline alkaloids from Corydalis impatiens using middle chromatogram isolated gel column coupled with positively charged reversed-phase liquid chromatography

Positively charged reversed-phase liquid chromatography was employed for the efficient preparative separation of isoquinoline alkaloids from Corydalis impatiens. Ten commercially available columns were compared for isoquinoline alkaloids analysis. While tailing, overloading, lower resolution, and buffer salts limited the application in purification of isoquinoline compounds of many of these columns, one positively charged reversed-phase C18 column (XCharge C18) overcame these drawbacks, allowing for favorable separation resolution, even when loading isoquinoline compounds on a larger, preparative scale. The general separation process is as follows. First, isoquinoline alkaloids are enriched with Corydalis impatiens extract via a middle chromatogram isolated gel column. After column selection, separation is performed on an XCharge C18 analytical column, from which two evident chromatographic peaks are readily obtained. Finally, two isoquinoline alkaloids (protopine and corydamine) are selectively purified on the XCharge C18 preparative column. These results demonstrate that a middle chromatogram isolated gel column coupled with positively charged reversed-phase liquid chromatography is effective for the preparative separation of isoquinoline alkaloids from Corydalis impatiens.

Alkaloids as Aldose Reductase Inhibitors, with Special Reference to Berberine

Aldose reductase is the rate-limiting enzyme of the polyol pathway that leads to conversion of glucose to sorbitol. Its increased activity, which results in abnormal activation of the polyol pathway, is implicated in the development of long-term complications of diabetes mellitus. Different plant species and their active components have shown potent in vitro and in vivo aldose reductase inhibitory activity. Among different phyto-constituents, alkaloids that contain isoquinoline/bis(isoquinoline) and related ring structures (such as berberine, palmatine, coptisine, and jateorrhizine) have shown very potent aldose reductase inhibitory activity. The structural activity relationship has revealed the importance of hydrophobic and hydrophilic groups of isoquinoline/bis(isoquinoline) for binding to an enzyme. The dioxymethylene group in the D ring (hydrophobic group) of these alkaloids binds tightly to the site adjacent to the anionic binding site (active site), while the methoxyl groups (polar) bind to the site adjacent to the nicotinamide ring of the coenzyme. On the basis of these findings, it may be proposed that the presence of isoquinoline/bis(isoquinoline) ring structures is the most important requirement for alkaloids to behave as potent aldose reductase inhibitors. Thus, other plants may also be screened for the same activity. The present review discusses these isoquinoline/bis(isoquinoline)-based alkaloids as aldose reductase inhibitors that may be used to manage diabetic complications and may substitute for the chemically synthesized aldose reductase inhibitors.

Electric Literature of 21806-61-1, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 21806-61-1 is helpful to your research.
