Simultaneous quantification of 11 isoquinoline alkaloids in Corydalis impatiens (Pall.) Fisch by HPLC

Isoquinoline alkaloids are the primary active ingredients of Corydalis, but an analytical method for quality assessment of the active ingredients in Corydalis impatiens (Pall). Fisch has not been reported. A new, simple, and multiple-component quantification method was developed for the simultaneous quantification of 11 isoquinoline alkaloids including capnoidine, chelianthifoline, bicuculline, protopine, isoapocavidine, apocavidine, cavidine, tetrahydroepiberberine, ochotensimine, tetrahydrocoptisine, and tetrahydrocorysamine in C. impatiens. Separation of the isoquinoline alkaloids was performed on a RP C-18 column (150 x 4.6 mm, 5 m) with potassium dihydrogen phosphate buffer (pH 2.5, adjusted by phosphoric acid)/acetonitrile (53:47, v/v) containing 0.3% sodium dodecyl sulfonate. The flow rate and detection wavelength were set at 1 mL/min and 295 nm, respectively. Full validation of the assay was carried out including linearity, precision, accuracy, stability, LOD, and limit of quantitation. All calibration curves showed a good linear relationship (r > 0.999) in test range. The results demonstrated that the developed method was reliable, rapid, and specific. Six batches of C. impatiens samples from different sources were determined using the established method. The contents of alkaloids ranged from 11.68 to 351.83 g/g. This method can be applied for quality evaluation and control of C. impatiens. Eleven isoquinoline alkaloids were first reported on simultaneous determination with HPLC.

Discovery of 4,6-and 5,7-Disubstituted Isoquinoline Derivatives as a Novel Class of Protein Kinase C zeta Inhibitors with Fragment-Merging Strategy

Two chemical series of novel protein kinase C zeta (PKC zeta) inhibitors, 4,6-disubstituted and 5,7-disubstituted isoquinolines, were rapidly identified using our fragment merging strategy. This methodology involves biochemical screening of a high concentration of a monosubstituted isoquinoline fragment library, then merging hit isoquinoline fragments into a single compound. Our strategy can be applied to the discovery of other challenging kinase inhibitors without protein-ligand structural information. Furthermore, our optimization effort identified the highly potent and orally available 5,7-isoquinoline 37 from the second chemical series. Compound 37 showed good efficacy in a mouse collagen-induced arthritis model. The in vivo studies suggest that PKC zeta inhibition is a novel target for rheumatoid arthritis (RA) and that 5,7-disubstituted isoquinoline 37 has the potential to elucidate the biological consequences of PKC zeta inhibition, specifically in terms of therapeutic intervention for RA.

Alkaloids and a flavonoid from aerial parts (leaves and twigs) of Duguetia furfuracea – Annonaceae

Duguetia furfuracea is a shrub of the Annonaceae family that occurs in several regions in Brazil. In the state of Mato Grosso do Sul this species often becomes an invading plant when the cerrado is turned into pastures. In the local folk medicine, its powdered seeds are mixed with water and used against pediculosis. and the infusion of twigs and leaves is used to treat rheumatism.. The present work led to the isolation and characterization from the aerial parts of the plant (leaves and twigs), of twelve isoquinoline alkaloids of aporphine oxoaporphine, bisbenzyltetrahydro-isoquinoline, benzyltetrahydro-isoquinoline and tetrahydroprotoberberine skeletons. In addition beta-sytosterol and the flavonoid isorhamnethin were obtained. The activity of these different patterns of isoquinoline skeleton and the flavonoid was tested against Trypanosoma cruzi, and only aporphinoid skeleton with (R)-configuration, (-)-asimilobine, was really effective against trypomastigotes (strain Y), killing approximately 72% of the parasites at a maximal concentration of 128.0 mu M (IC50 57.2 mu M). The trypanocidal activity of the alkaloids and the flavonoid have been investigated.
