alpha-[6-[[(S)-1-(Ethoxycarbonyl)-3-phenylpropyl]amino]-5-oxoperhydro -1,4-thiazepin-4-yl]acetic acids (monoester monoacids) and their dicarboxylic acids having the hydrophobic substituents at the 2- or 3-position of the thiazepinone ring were prepared and assayed for angiotensin-converting enzyme (ACE) inhibitory activity. The dicarboxylic acids having the pseudoequatorial amino groups at the 6-position and the pseudoequatorial hydrophobic substituents at the 2- or 3-position of the chair conformation of the thiazepinone ring had potent in vitro inhibitory activity. The monoester monoacids having the hydrophobic substituents at the 2-position suppressed pressor response to angiotensin I for a longer duration than those having the substituents at the 3-position when administered orally. The structure-activity relationship was studied by conformational energy calculations of the thiazepinone ring.

Compounds of formula (I): A-(X1-ONO2)S wherein A is a known ACE-inhibitor such as enalapril and X1 is a spacer such as a (C1-C6)-alkylene. The complete definition of A and X1 is given in claim 1. The compounds can be used as ACE-inhibitors for the treatment of cardiovascular and renal diseases and inflammatory processes. The example of formula (1) has an improved pharmacological activity when compared with the structurally closest related prior art compound.

Stereoselective Synthesis of Freidinger Lactams Using Oxaziridines Derived from Amino Acids

日期:1997.2.1
Conformationally restrained dipeptidyl lactams are building blocks for the synthesis of peptidomimetics, including Freidinger lactams (Figure 1). Few synthetic methodologies toward such moieties allow for incorporation of a stereodefined substituent on the ring nitrogen (i.e., corresponding to an amino acid side chain). Enantiopure Freidinger lactams were obtained by (1) condensation of (S)-tert-butoxycarbonyl
