  Conformationally Constrained Analogues of Diacylglycerol (DAG). 27. Modulation of Membrane Translocation of Protein Kinase C (PKC) Isozymes α and δ by Diacylglycerol Lactones (DAG-lactones) Containing Rigid-Rod Acyl Groups

  摘要：

  Highly rigid and geometrically well-defined rods composed of ethynylene-substituted aromatic spacers [oligo(p-phenyleneethynylene), OPE] were incorporated as acyl moieties on diacylglycerol lactones (DAG-lactones) and investigated for their ability to bind to protein kinase C (PKC) and translocate PKC alpha and delta isoforms to plasma and internal membranes. The kinetics of PKC translocation were correlated with biological responses, viz. ERK phosphorylation, induction of IL-6 secretion, inhibition of cell proliferation, and induction of cellular attachment, that display very different time courses. Because OPE rods assemble through noncovalent forces and form stable films, they may influence the microdomain environment around the DAG-lactone membrane-binding site. A comparison of two DAG-lactones (1 and 10), one with two PE units (1) and the other with an equivalent flexible acyl chain (10) of matching lipophilicity, clearly demonstrated the effect of the rigid OPE chain in substantially prolonging the translocated state of both PKC alpha and delta.

  Diacylglycerol lactones built with a rigid 4-[(methylphenyl)ethynyl]phenyl rod that is separated from the exocyclic acylcarbonyl of the DAG-lactone core by a spacer unit of variable length were synthesized and studied. Binding affinities for a panel of classical and novel PKC isozymes in two different phospholipid environments, one corresponding to the plasma membrane of cells, were determined. The kinetics and site of translocation for the PKC isozymes alpha and delta upon treatment with the compounds were also studied as well as the early response of ERK phosphorylation and the late response of induction of apoptosis in the human prostatic carcinoma cell line LNCaP. Finally, the compounds were evaluated in terms of their interaction with biomimetic lipid/polydiacetylene membranes by the associated chromatic response. The different spatial disposition of the rigid structural motif on the DAG-lactones contributes to differential activity.
