Difluoromethyleneketone retroamide, a versatile concept of inactivation of proteolytic enzymes

The synthesis of difluoromethyleneketone retroamides is described. Several examples of application to aspartyl or seryl proteases illustrate the versatility of this inactivation concept. Copyright

Novel synthesis of a dihydroxyethylene isostere of renin inhibitors

A dihydroxyethylene isostere, (2S,3R,4S)-4-amino-5-cyclohexyl-1-morpholino-2,3-pentanediol (ACMP, 1), which is a component of non-peptidic, orally active, low-molecular-weight renin inhibitors, was synthesized stereospecifically starting from 3-cyclohexyl

Dipeptide Isosteres. 2. Synthesis of Hydroxyethylene Dipeptide Isostere Diastereomers From a Common γ-Lactone Intermediate. Preparation of Renin and HIV-1 Protease Inhibitor Transition State Mimics.

A general strategy for the synthesis of the hydroxyethylene dipeptide isostere diastereomers C or D has been developed.The syntheses proceeded through a common γ-lactone intermediate A or B.The C(3α)γ-lactone diastereomer A was prepared from the N-Cbz pro

Renin inhibitors. I. Synthesis and structure-activity relationship of transition-state inhibitors containing homostatine analogues at the scissile bond

The synthesis and structure-activity relationships of transition-state renin inhibitors containing the homostatine analogues at the scissile bond are described. These inhibitors incorporate the amino acid side chains corresponding to positions 7-12 (Psub

Stereoselective silver triflate-mediated iodocyclization of carbamates

Iodocyclization of carbamates involving electron-deficient olefins, (i.e. α,β-unsaturated esters) is greatly facilitated by the use of silver(l) triflate and proceeds with excellent trans ring stereoselectivity. During this process, the resultant iodides can undergo epimerization, the rate of which is solvent-dependent.

PEPTIDES RETROVIRAL PROTEASE INHIBITORS COMPRISING 2-AMINO-2-METHYLPROPIONIC ACID

Antiviral peptides of the formula STR1 in which W is an amino protecting group,A,B,D,E and L each independently is a direct bond, or a radical of the formula STR2 R 1 and R 2 each independently is cycloakyl or optionally substituted alkyl or alkenyl,Y is--NHR 10, andR 10 is cycloalkyl or optionally substituted alkyl, and their physiologically acceptable salts.The formula includes a 2-amino-2-methylpropionic acid (AiB) residue, which may optionally be protected, as the N-terminal α-amino acid. The peptides are expected to be useful as medicaments, in particular as antiviral agents in human and veterinary medicine. The peptides are shown to inhibit aspartyl proteases including human immunodeficiency virus (HIV) protease, to have anti-HIV activity and to inhibit the proliferation of HIV in HIV-I infected human lymphocytes. The peptides are expected to be useful in treating patients having HIV related disorders such as ARC and AIDS.
