- Synthesis of the HIV-proteinase inhibitor Saquinavir: A challenge for process research
-
The task of process research, namely developing efficient, economically and technically as well as ecologically feasible syntheses in time, is demonstrated on the HIV-proteinase inhibitor Saquinavir (1), a complex molecule comprising six stereo-centres. Based on the first 26-step research synthesis furnishing a 10% overall yield, process research established a new, short 11-step synthesis affording a 50% overall yield.

- Asymmetric synthesis of optically active decahydroisoquinolines useful in HIV-1 protease inhibitor synthesis
-
An efficient synthesis of amino acid ester 8 is described featuring an asymmetric aza-Diels-Alder reaction of diene 5 and chiral imine 6 which establishes the asymmetry at C-3. Hydrogenation of 7 provides 8 with the desired asymmetry at C-4a and C-8a.

- A Series of Potent HIV-1 Protease Inhibitors Containing a Hydroxyethyl Secondary Amine Transition State Isostere: Synthesis, Enzyme Inhibition, and Antiviral Activity
-
A series of HIV-1 protease inhibitors containing a novel hydroxyethyl secondary amine transition state isostere has been synthesized.The compounds exhibit a strong preference for the (R) stereochemistry at the transition state hydroxyl group.Molecular modeling studies with the prototype compound 11 have provided important insights into the structural requirements for good inhibitor-active site binding interaction.N-Terminal extension of 11 into the P2-P3 region led to the discovery of 19, the most potent enzyme inhibitor in the series (IC50 = 5.4 nM). 19 was shown to have potent antiviral activity in cultured MT-4 human T-lymphoid cells.Comparison of analogs of 19 with analogs of 1 (Ro31-8959) demonstrates that considerably different structure-activity relationships exist between these two subclasses of hydroxyethylamine HIV-protease inhibitors.
