Modulation of plant and bacterial polyamine metabolism during the compatible interaction between tomato and Pseudomonas syringae
(Elsevier Gmbh, 2018-12)
The polyamines putrescine, spermidine and spermine participate in a variety of cellular processes in all organisms. Many studies have shown that these polycations are important for plant immunity, as well as for the virulence ...
Polyamines and related nitrogen compounds in the chemotherapy of neglected diseases caused by kinetoplastids
(Bentham Science Publishers, 2018-05)
Neglected diseases due to the parasitic protozoa Leishmania and Trypanosoma (kinetoplastids) affect millions of people worldwide, and the lack of suitable treatments has promoted an ongoing drug discovery effort to identify ...
Dynamics of physiological and biochemical changes during somatic embryogenesis of Acca sellowiana
(SpringerHeidelberg, 2014-03)
Feijoa (Acca sellowiana [O. Berg] Burret [Myrtaceae]) is a native fruit species of southern Brazil and northern Uruguay. This species is amenable to somatic embryogenesis and therefore suitable as a model system for ...
Amino acid and polyamine membrane transporters in Trypanosoma cruzi: biological function and evaluation as drug targets
(Bentham Science Publishers, 2019-12)
Amino acids and polyamines are involved in relevant processes for the parasite Trypanosoma cruzi, like protein synthesis, stress resistance, life cycle progression, infection establishment and redox balance, among others. ...
Physiological importance of polyamines
(2017)
Polyamines are polycationic molecules that contain two or more amino groups (-NH3 +) and are present in all eukaryotic and prokaryotic cells. Polyamines are synthesized from arginine, ornithine, and proline, and from ...
Unravelling ties in the nitrogen network: Polyamines and nitric oxide emerging as essential players in signalling roadway
(Wiley Blackwell Publishing, Inc, 2020-09)
Nitrogen (N) is a central mineral nutrient essential for plant development and growth. It is usually scarcely found in soils, so the knowledge of the overall plant N metabolism deserves substantial attention. Polyamines ...
1,n-Diamines. Part 3: Microwave-assisted synthesis of N-acyl-N′-arylhexahydropyrimidines and hexahydro-1,3-diazepines
(Pergamon-Elsevier Science Ltd, 2011-10)
In this Letter we present a method for the synthesis of N-acyl-N´-arylhexahydropyrimidines 1, by ring closure of N-acyl-N´-aryl-1,3-propanediamines 3 with formaldehyde. Cyclodehydrations were performed in aqueous medium ...
1,n-Diamines. Part 4: synthesis of 1-aryl-2-alkyl-1,4,5,6,7,8-hexahydro-1,3-diazocines
(Elsevier, 2011-11)
In this Letter we present the synthesis of hitherto unreported 1-aryl-2-alkyl-1,4,5,6,7,8-hexahydro-1,3-diazocines 1. Cyclic amidines 1 were synthesized by PPSE promoted ring closure of N-acyl-N0-arylpentamethylenediamines ...
