Brassinolide-2,3-acetonide: A brassinolide-induced rice lamina joint inclination antagonist

Bioorganic and Medicinal Chemistry, 2013
A novel chemical tool compound that is an antagonist of brassinolide (BL, 1)-induced rice lamina joint inclination was developed. Although 2-O-, 3-O-, 22-O-, or 23-O-methylation of BL causes a critical decrease in biological activity,(5) a crystal structure of the extracellular leucine-rich repeat (LRR) domain of BRASSINOSTEROID-INSENSITIVE I (BRI1 ...

Brassinolide-induced elongation

Physiologia Plantarum, 1992
The promotive effects of brassinosteroids (BRs) on elongation seem general, as members of the family affect young vegetative tissue in fifteen species (listed in Sasse, 1991a). There is also a specific effect, as 24-epibrassinolide (24epiBL) forms part of the sequential response in young elongating tissue (Sasse, 1985). The case for BRs as a new family

Stereocontrolled synthesis of the brassinolide side-chain: formal synthesis of brassinolide

Journal of the Chemical Society, Perkin Transactions 1, 1988
The stereoselective introduction of the brassinolide side-chain, having a (20S,22R,23R,24S)-22,23-diol functionality, was examined. The catalytic reduction of (20S,22R,24Z)-6β-methoxy-23-oxo-3α,5-cyclo-5α-stigmast-24(28)-eno-29,22-lactone (11), derived from the 20-carbaldehyde (7) and 3-isopropyl-2-lithiofuran in three steps, afforded (20S,22R,23R,24S)-

A formal synthesis of brassinolide

Tetrahedron Letters, 1997
Abstract Enzyme-catalysed differentiation of hydroxy groups in a C 2v -shaped tetraol-sulfide, combined with a E -stereoconvergent Ramberg-Backlund process, allowed to prepare pure (2 S )-2,3-dimethyl-1-iodobutane, which could be coupled with a 3,5-cyclopregnane-20-thiomethanol derivative so as to give an efficient precursor of the title vegetal ...

Improved synthesis of brassinolide

Journal of the Chemical Society, Perkin Transactions 1, 1996
Brassinolide has been synthesized from stigmasterol in an overall yield of 7%. The key step in the synthesis is aldol condensation of 2α,3α-isopropylidenedioxy-6-oxo-23,24-dinor-5α-cholan-22-al with 3-isopropylbut-2-enolide carried out at – 78 °C, which gives a product with 22R,23R stereochemistry in high yield.

Stereoselective synthesis of the brassinolide side chain; novel syntheses of brassinolide and related compounds

Tetrahedron, 1990
Abstract A stereoselective synthesis of the brassinolide side chain involves the lactonization of Z-10 under acidic condition to give an α,β-unsa-turated-δ-lactone 11 with the inversion of the configuration at C-22 of the epoxy steroid in quantitative yield.

In silico exploration for agonists/antagonists of brassinolide

Bioorganic & Medicinal Chemistry Letters, 2016
Brassinolide (BL) is a plant steroid hormone that is necessary for stem elongation and cell division. To date more than 70 steroidal BL-like compounds, which are collectively named as brassinosteroids, have been identified. However, non-steroidal compounds that mimic BL have not been reported yet, which can be used as plant growth regulators.
