Conformationally Constrained Analogues of Diacylglycerol (DAG). 25. Exploration of the sn-1 and sn-2 Carbonyl Functionality Reveals the Essential Role of the sn-1 Carbonyl at the Lipid Interface in the Binding of DAG-Lactones to Protein Kinase C
摘要:
Diacylglycerol (DAG) lactones with altered functionality (C=O -> CH2 or C=O -> C=S) at the sn-1 and sn-2 carbonyl pharmacophores were synthesized and used as probes to dissect the individual role of each carbonyl in the binding to protein kinase C (PKC). The results suggest that the hydrated sn-1 carbonyl is engaged in very strong hydrogen-bonding interactions with the charged lipid headgroups and organized water molecules at the lipid interface. Conversely, the sn-2 carbonyl has a more modest contribution to the binding process as a result of its involvement with the receptor (Cl domain) via conventional hydrogen bonding to the protein. The parent DAG-lactones, E-6 and Z-7, were designed to bind exclusively in the sn-2 binding mode to ensure the correct orientation and disposition of pharmacophores at the binding site.

The invention relates to hexenal derivatives of general structure (I), in which one of the bonds represented by dashes is a C—C single bond and the other is a C═C double bond, with the proviso that the C═C double bond can have a Z or E configuration, provided that it is in the C¾ position. Said derivatives are characterised by an interesting and original perfume that pervades a wide area and are suitable for use as perfumes, for example in cosmetic preparations, technical products or the alcohol-based perfume industry.
