First total synthesis of 1,2-dipalmitoyl-3-(N-palmitoyl-6′-amino-6′-deoxy-α-d-glucosyl)-sn-glycerol—a glycoglycerolipid of a marine alga with a high inhibitor activity against human Myt1-kinase
The first total synthesis of 1,2-dipalmitoyl-3-(N-palmitoyl-6'-amino-6'-deoxy-alpha-D-glucosyl)-sn-glycerol, a glycoglycerolipid isolated from a marine alga extract, is described. Starting from alpha-methylglucopyranoside the multistep strategy allows the stereoselective synthesis of the final compound using various protective group procedures as well as derivatization of partial molecule domains. The latter offers the development of lead structures for inhibitors of human Myt1-kinase. (C) 2009 Elsevier Ltd. All rights reserved.

In the human cell cycle, the Myt1 kinase is a crucial regulator of the G2/M transition. Because this membrane-associated kinase is hard to obtain and assay, there is a distinct lack of data so far. Here we report the derivatization of a glycoglycerolipid which was shown previously to be active in a Myt1 activity assay. These compounds were tested in a binding assay together with a set of common kinase inhibitors against a full-length Myt1 expressed in a human cell line. Dasatinib exhibited nanomolar affinity whereas broad coverage inhibitors such as sunitinib and staurosporine derivatives did not show any effect. We also carried out docking studies for the most potent compounds allowing further insights into the inhibitor interaction of this kinase. The glycoglycerolipids showed no significant effects in the binding assay, endorsing the idea of a mechanism of action distant from the active site. (C) 2012 Elsevier Masson SAS. All rights reserved.
