Isoquinoline alkaloids from Berberis Vulgaris subsp. Australis
Abstract Sixteen isoquinoline alkaloids were isolated from Berberis vulgaris subsp. australis . In addition to quaternary protoberberines and bisbenzylisoquinolines, a new seco - bis… Expand
Antigens and antibodies in sera from human cases of epilepsy or taeniasis from an area of Mexico where Taenia solium cysticercosis is endemic.
Human neurocysticercosis is an important parasitic disease in developing countries. Most epidemiological studies on the disease have used antibody-based assays that allow the detection of… Expand
Alkaloids from Fumaria sepium and Fumaria agraria
The plants of genus Fumaria L., which encompasses about 40 species (Southon and Buckingham, 1989), are annual herbs which have a wide distribution from India to Macaronesia. Twenty-two species are… Expand

Abstract Serial measurements of the individual porphyrins were done in 11 patients with porphyria cutanea tarda treated by repeated venesections. The effectiveness of this therapy was more… Expand
Ismine and related alkaloids from Lapiedra martinezii
Abstract Three phenantridine alkaloids have been isolated for the first time from natural sources ( Lapiedra martinezii ). Their structures suggest a biosynthetic relationships with ismine.
Alkaloid N-oxides of amaryllidaceae
Abstract Ungiminorine N -oxide was isolated from Pancratium maritimum , and homolycorine N -oxide and O -methyl lycorenine N -oxide from Lapiedra martinezii . These compounds represent the first… Expand
Synthesis of Homoprotoberberines and 8-Oxoprotoberberines by Sequential Bicyclization of Phenylacetamides
Abstract The reaction of phenylacetamides with oxalyl chloride/Lewis acid provides a convergent, high-yield entry to C-homoprotoberberine and 8-oxoprotoberberine alkaloids from available starting… Expand
The palladium(0) Suzuki cross-coupling reaction as the key step in the synthesis of aporphinoids
Abstract We report a flexible approach to the total synthesis of 4,5-dioxoaporphines based on the palladium(0) catalyzed Suzuki cross-coupling of phenylboronic acids with sterically hindered 2-bromo… Expand
