Synthesis of 2-benzothienyl carbonyl 4-arylpiperazines as novel delavirdine analogs

A novel series of 2-benzothienyl carbonyl arylpiperazines (6a-f) was synthesized as potential HIV nonnucleoside reverse transcriptase inhibitors (NNRTIs). Preparation of the derivatives was performed by reacting benzo[b]thiophene carbonyl chloride (5) with a series of substituted 4-arylpiperazines

Synthesis of benzo[b]thiophene carboxamides connected to 4-arylpiperazines through a benzylic spacer: Potential Ligands with 5-HT1A binding affinity

New benzothiophene arylpiperazine derivatives 8 (a-f) were synthesized as potential serotoninergic agents with 5-HT1A receptor affinity. Preparation of the derivatives was performed by treating N-[2-(chloromethyl)phenyl]-4,7-dimethoxybenzo[b]thiophene-2-carboxamide (7) with a series of substituted 4-arylpiperazines

Growing knowledge: an overview of Seed Plant diversity in Brazil

Abstract An updated inventory of Brazilian seed plants is presented and offers important insights into the country's biodiversity. This work started in 2010, with the publication of the Plants and Fungi Catalogue, and has been updated since by more than 430 specialists working online. Brazil is home to 32,086 native Angiosperms and 23 native Gymnosperms, showing an increase of 3% in its species richness in relation to 2010. The Amazon Rainforest is the richest Brazilian biome for Gymnosperms, while the Atlantic Rainforest is the richest one for Angiosperms. There was a considerable increment in the number of species and endemism rates for biomes, except for the Amazon that showed a decrease of 2.5% of recorded endemics. However, well over half of Brazillian seed plant species (57.4%) is endemic to this territory. The proportion of life-forms varies among different biomes: trees are more expressive in the Amazon and Atlantic Rainforest biomes while herbs predominate in the Pampa, and lianas are more expressive in the Amazon, Atlantic Rainforest, and Pantanal. This compilation serves not only to quantify Brazilian biodiversity, but also to highlight areas where there information is lacking and to provide a framework for the challenge faced in conserving Brazil's unique and diverse flora
