This chapter presents an overview of the chemistry and pharmacology of the alkaloids found in species of the Annonaceae family. The occurrence of alkaloids from Annonaceae species, as well as their chemical structures and pharmacological activities are summarized in informative and easy-to-understand tables. Within the Annonaceae family, the genera Annona, Duguetia, and Guatteria have led to ma...

Evidence was presented in a previous paper' that a hybrid substance, encountered after an antigenic character (ch4) of Streptopelia chinensis was transferred to S. risoria, resulted from the interaction of nonallelic genes. Specifically, the cha4 cellular antigen from chinensis showed no hybrid substance when present in backcross individuals that were homozygous for an independently inherited c...

A methylene chloride extract of the pulp of Annona muricata L. was fractionated in search for scarcely functionalized Annonaceous acetogenins (type E). Previously known C-35 and C-37 mono-epoxy unsaturated compounds, epomuricenins-A and -B (1+2) and epomusenins-A and -B (3+4), were obtained. Two new mono-epoxy saturated C-35 representatives, epomurinins-A and -B (5+6) were also isolated.

In the town of Bakel, the French scientist Le Dantec encountered 20 patients showing symptoms of “vesical Schistosomiasis” in 1908. This represents the first record of schistosomiasis cases in Senegal [1]. In line with the country’s great diversity in aquatic habitat within Senegal, at least five species of snails are known to act as intermediate hosts for human infective schistosomes: Bulinus ...

Uma síntese total e eficiente da (+) e (-)-tripargina, alcalóide b-carbolínico isolado da pele da rã africana K. Senegalensis, foi realizada em 6 etapas e 38% de rendimento global, a partir da triptamina, tendo como base a construção do sistema b-carbolínico via reação de BischlerNapieralski e a redução enantiosseletiva do intermediário diidro-b-carbolínico via reação de transferência de hidrog...

We report the main characteristics of 'Bacillus dakarensis' P3515T sp. nov., 'Bacillus sinesaloumensis' P3516T sp. nov., 'Gracilibacillus timonensis' P2481T sp. nov., 'Halobacillus massiliensis' P3554T sp. nov., 'Lentibacillus massiliensis' P3089T sp. nov., 'Oceanobacillus senegalensis' P3587T sp. nov., 'Oceanobacillus timonensis' P3532T sp. nov., 'Virgibacillus dakarensis' P3469T sp. nov. and ...

Aspects of the feeding habits and diet of juveniles of the cassava croaker Pseudotolithus senegalensis (Valenciennes, 1833) (Sciaenidae) and bigeye grunt Brachydeuterus auritus (Valenciennes, 1831) (Haemulidae) in the inshore waters of Cape Coast, Ghana are reported in the study. Both species had a similar diet consisting of larvae of fish, shrimps and cuttlefish. The croaker ingested prey up t...

A total synthesis of annonacin (1) was accomplished by using versatile chiral building block 2 for synthesizing the mono-tetrahydrofuran (THF) annonaceous acetogenins.
