Synthesis and Biological Activity of New Brassinosteroid Analogs of Type 24-Nor-5β-Cholane and 23-Benzoate Function in the Side Chain
Autor: Nitza Soto, Karoll Ferrer, Katy Díaz, César González, Lautaro Taborga, Andrés F. Olea, Héctor Carrasco, Luis Espinoza
Publikováno v: International Journal of Molecular Sciences, Vol 22, Iss 9, p 4808 (2021)
Brassinosteroids are polyhydroxysteroids that are involved in different plants’ biological functions, such as growth, development and resistance to biotic and external stresses. Because of its low abundance in plants, much effort has been dedicated

Synthesis of New Brassinosteroid 24-Norcholane Type Analogs Conjugated in C-3 with Benzoate Groups
Autor: Karoll Ferrer, Katy Díaz, Miroslav Kvasnica, Andrés F. Olea, Mauricio Cuellar, Luis Espinoza
Publikováno v: Molecules, Vol 26, Iss 4, p 1173 (2021)
The metabolism of brassinosteroid leads to structural modifications in the ring skeleton or the side alkyl chain. The esterification and glycosylation at C-3 are the most common metabolic pathways, and it has been suggested that conjugate brassinoste

Publikováno v: International Journal of Molecular Sciences, Vol 22, Iss 1, p 155 (2020)
Brassinosteroids are a class of plant hormones that regulate a broad range of physiological processes such as plant growth, development and immunity, including the suppression of biotic and abiotic stresses. In this paper, we report the synthesis of

Insights into the Structural Requirements of Potent Brassinosteroids as Vegetable Growth Promoters Using Second-Internode Elongation as Biological Activity: CoMFA and CoMSIA Studies
Autor: Karoll Ferrer-Pertuz, Luis Espinoza, Jaime Mella
Publikováno v: International Journal of Molecular Sciences, Vol 18, Iss 12, p 2734 (2017)
In the present study, we have employed the ligand-based drug design technique, 3D-QSAR, through a comparative molecular field analysis (CoMFA) and a comparative molecular similarity indices analysis (CoMSIA) to determine the key factors for the plant

Natural brassinosteroids possess a 22R, 23R configuration that appears essential for biological activity. It is, therefore, interesting to elucidate if the activity of brassinosteroids with a short side chain depends on the C22 configuration. Herein,
