Together with a tentative mechanism for the mode of action, a model has been derived that can be used to design and prepare active SL analogs.
WebBackground: Some lactones prevent protein Myb-dependent gene expression. Objective: The object is to calculate inhibitors of Myb-brought genetic manifestation. Methods: Linear quantitative structure–potency relations result expanded, among sesquiterpene lactones of a variety of macrocycles (pseudoguaianolides, guaianolides, eudesmanolides and … WebMolecules of these natural SLs are composed of a tricyclic lactone ring (ABC-ring) and a butenolide ring (D-ring) that are connected by an enol-ether linkage, where the bioactiphore for germination resides in the CD part (Zwanenburg et al., 2009; Zwanenburg and Blanco-Ania, 2024). Orobanche and Striga weeds need their plant hosts to survive.
Webon the assumption that the bioactiphore required for bioactivity in SLs is the D-ring. Although the contribution of the A-ring to activity is low, when present it should have the required stereochemistry (molecular freedom) to get reasonably active analogs.[18] We have demonstrated that structural modification Webidentification of the bioactiphore in SLs, the D-ring, which is required for activity. Although the contribution of the A-ring to activity is low, it should have the required …
WebJan 1, 2014 · The bioactiphore involves the CD part of the molecule (Zwanenburg et al. 2009). A full understanding of the importance of stereochemistry in bioactivity has been possible with the total synthesis of all its eight stereoisomers of strigol and the control of their activity on parasitic seeds (Reizelman et al. 2000).

Endogenous SLs are classified into two main types (strigol and orobanchol type) based on whether the C ring is α- or β-oriented (Cui. 2014). Strigol and orobanchol are canonical SLs as both have A, B, C, and D rings (Butler. dave b owner of a 2016 subaru outback from paWebFeb 16, 2009 · The bioactiphore in this strigolactone family of stimulants is deduced from a structure–activity relationship and shown to reside in the CD part of the stimulant molecule.
