  Conformationally constrained analogues of diacylglycerol (DAG). 15.1 The indispensable role of the sn-1 and sn-2 carbonyls in the binding of DAG-lactones to protein kinase C (PK-C)

  摘要：

  The binding mode of DAG-lactones to PK-C was investigated using the C1b domain from the Xray structure of the phorbol ester/C1b complex of PK-C delta as a template. Modeling experiments revealed two binding alternatives in which one of the carbonyls of the DAG lactones remained uninvolved with the protein. Experimentally, however, the removal of either sn-1 or sn-2 carbonyls caused a dramatic drop in binding affinity towards PK-C. Although it was not possible to discriminate between the two binding alternatives of the DAG-lactones, the study demonstrates an important role for the additional carbonyl group. The function of this group could be equivalent to that of the C-9(OH)/C-13 (C=O) motif in phorbol esters, which also appears free of interactions in the phorbol ester/C1b complex. This role presumably reflects interaction with the phosholipid head groups required for high affinity binding under the conditions of the biological assays. (C) 1998 Elsevier Science Ltd.

  Conformationally Constrained Analogues of Diacylglycerol. 10. Ultrapotent Protein Kinase C Ligands Based on a Racemic 5-Disubstituted Tetrahydro-2-furanone Template

  摘要：

  5,5-Bis(hydroxymethyl)tetrahydro-2-furanone and its isomer 4,4-bis(hydroxymethyl)tetrahydro-2-furanone were investigated as possible templates for the construction of conformationally constrained analogues of the biologically important second messenger, diacylglycerol (DAG). The former lactone contains embedded within its structure an exact glycerol moiety, while in the latter the ring oxygen has been transposed to the other side of the carbonyl group. Al target compounds were synthesized as racemates from 1,3-dihydroxy-2-propanone. The 5,5-bis(hydroxymethyl)tetrahydro-2-furanone proved to be the better template for the construction of DAG surrogates that were demonstrated to have high binding affinities for the biological target, protein kinase C (PK-C). The simplest target compounds derived from this template (3e and 3f) have one of the hydroxyl moieties functionalized either as a myristate or as an oleate ester. The simplest target compound (9e) derived from the ineffective 4,4-bis(hydroxymethyl)tetrahydro-2-furanone template was investigated only with a myristoyl acyl chain. Reducing the long acyl chain to an acetyl moiety and attaching a compensating lipophilic chain to the lactone ring as an alpha-alkylidene moiety produced compounds 10e and 10f(Z-isomers) and 11e and 11f(E-isomers), which were constructed on the more effective 5,5-bis(hydroxymethyl)tetrahydro-2-furanone template. Targets 14c (Z-isomer) and 15c (E-isomer) were derived, in turn, from 4,4-bis(hydroxymethyl)tetrahydro-2-furan. The affinities of these ligands for PK-C were assessed in terms of their ability to displace bound [H-3-20]phorbol 12,13-dibutyrate (PDBU) from the single isozyme PK-C alpha. The biological data support the hypothesis that the increase in binding affinity for PK-C shown by some of these constrained DAG mimetics appears to be entropic in nature. Two of the designed ligands (10e and 10f) showed the highest affinities (34 and 24 nM, respectively) reported so far for a DAG analogue. Assuming that the interaction between these racemic compounds and PK-C is stereospecific, the potency of the active enantiomer is anticipated to double.
