The Pyrrolo[2,1-a]isoquinoline Alkaloids
2011The present chapter describes isolation, biogenetic proposals, and syntheses of the natural products 1-4 and 10-11 with a pyrrolo[2,1-a]-isoquinoline framework. Moreover, the syntheses of some structural analogs are discussed. The pyrrolo[2,1-a]isoquinolines are of interest due to their promising biological activities.

The Effect of Isoquinoline Alkaloids on Opiate Withdrawal
Current Medicinal Chemistry, 2006Our interest has been centered on isoquinoline alkaloids obtained from Argemone mexicana (Papaveraceae), Aristolochia constricta (Aristolochiaceae) and the opium alkaloid, papaverine. In this respect, the effect of these isoquinoline alkaloids was investigated on contractions induced by naloxone of isolated guinea pig ileum acutely exposed to morphine ...

Isoquinoline alkaloids as prolyl oligopeptidase inhibitors
Fitoterapia, 2015Prolyl oligopeptidase is a cytosolic serine peptidase that hydrolyses proline-containing peptides at the carboxy terminus of proline residues. It has been associated with schizophrenia, bipolar affective disorder, and related neuropsychiatric disorders and therefore may have important clinical implications.

Metabolic Engineering in Isoquinoline Alkaloid Biosynthesis
Current Pharmaceutical Biotechnology, 2007Higher plants produce diverse classes of metabolites. Metabolic engineering offers tremendous potential to improve the production and quality of these chemicals. This report summarizes the possibility of using metabolic engineering in benzylisoquinoline alkaloid biosynthesis.

Antimicrobial Activity of Some Isoquinoline Alkaloids
Archiv der Pharmazie, 1991AbstractThe isoquinoline alkaloids are of great importance to humanity because of their medicinal value and different structure. During the last ten years, many isoquinoline alkaloids were isolated from Fumaria and Corydalis species growing in Turkey1—6).There have been many researches on the antimicrobial activity of extracts of higher plants, but ...

Isoquinoline Alkaloids and Chemotaxonomy
2019The isoquinoline alkaloids are a class of secondary metabolites classified into different groups, being the aporphinoids the most representative class. They are considered the second-largest class of alkaloids in terms of structural diversity staying behind only of indole alkaloids.

Extractions of isoquinoline alkaloids with butanol and octanol
Fitoterapia, 2010Six different isoquinoline alkaloids (sanguinarine, chelerythrine, berberine, coptisine, allocryptopine, and protopine) were extracted by butanol and octanol from aqueous solution, pH 4.5. The samples were analyzed by HPLC. Butanol extraction was non-selective, alkaloids passed into organic phase in 83-98%.

Representatives of eleven different classes of isoquinoline alkaloids inhibit Na+, K+-ATPase and Mg2+-ATPase in rat brain microsomal preparations. In most cases the Na+, K+-ATPase is more sensitive than Mg2+-ATPase to inhibition by the alkaloids.
