ESPINOZA C, LUIS  e  CORTES M, MANUEL. SINTESIS Y ACTIVIDAD BIOLOGICA DE ANALOGOS DE BRASINOESTEROIDES. Bol. Soc. Chil. Quím. [online]. 2002, vol.47, n.4, pp. 511-516. ISSN 0366-1644.  http://dx.doi.org/10.4067/S0366-16442002000400024.

From deoxycholic acid 6 two new brassinosteroids analogs bearing oxygenated fuctions in ring C, side chain and cis A/B ring juntion were synthesized. The plant growth-promoting activites of compound 4a and 5 was tested by the hypocotiles elongation and cothyledons expansion of radish bioassay. The compounds 4a showed growth promoting activity at 10-5 mg/mL concentration in both bioassay, while that the compound 5 showed inhibiter effect in the cothyledons expansion test at the same concentration.

Palavras-chave : Synthesis; Brassinosteroids; Phytohormones; Hypocotiles; Cothyledons.
