Resolution and regioselective protection of glutamic acid analogues. I- resolution of diastereomeric α-boroxazolidone derivatives.
摘要:
Diastereomeric alpha-boroxazolidone gamma-phenylethylamide (or gamma-phenylethanolamide) derivatives of 2-, 3- or 4-substituted glutamic acid analogues have been separated by silicagel chromatography, resulting, after deprotection, in a practical method for the resolution of most of these unnatural amino acids.

A method for the synthesis of daptomycin or a daptomycin analogue is carried out on a resin to form a linear precursor followed by a serine ligation macrocyclization in solution. Daptomycin analogues can differ from daptomycin by substitution of amino acids residues and/or deletion or addition of amino acid residues. Daptomycin analogues can include a different fatty acid in the side arm of the daptomycin analogue.

The invention provides nitrile-containing protease inhibitors caged to ruthenium compounds. The nitrile-caged ruthenium compounds provide inactivated inhibitors that can be delivered to surface or site for activation, for example, but exposure to light. The invention also provides methods for delivering protease inhibitors to subjects for the therapeutic treatment of conditions such as cancer.
The present invention relates to compounds of Formula (I):
1
wherein A
1
is methylene, ethylene or propylene group and A
2
is N or CR
