A series of novel HIV-1 protease inhibitors based on the (hydroxyethylamino)-sulfonamide isostere incorporating substituted phenyls and benzheterocycle derivatives bearing rich hydrogen bonding acceptors as P 2 ligands were synthesized. Prolonged chain linking the benzhereocycle to the carbonyl group resulted in partial loss of binding affinities. Introduction of a small alkyl substituent with appropriate size to the -CH2- of P1-P2 linkage as a side chain resulted in improved inhibitory potency, and in this study, isopropyl was the best side chain. Replacement of the isobutyl substituent at P 1′group with phenyl substituent decreased the inhibitory potency. One of the most potent inhibitor, compound 23 showing high affinity to HIV-1 protease with an IC50 value of 5 nm, also exhibited good anti-SIV activity (EC50 = 0.8 μm) with low toxicity (TC 50 > 100 μm). The flexible docking of inhibitor 23 to HIV-1 protease active site rationalized the interactions with protease.
Highly diastereoselective catalytic Meerwein-Ponndorf-Verley reductions

Very practical synthesis of ephedrine analogues in high yields and enantiopurity was realized by a highly diastereoselective Meerwein-Ponndorf- Verley (MPV) reduction of protected α-amino aromatic ketones using catalytic aluminum isopropoxide. The high anti selectivity resulted from the chelation of the nitrogen anion to the aluminum. In contrast, high syn selectivity was obtained with α-alkoxy ketones and other compounds via Felkin-Ahn control.

Combinatorial libraries of HIV and FIV protease inhibitors are characterized by alpha-keto amide or hydroxyethylamine core structures flanked by on one side by substituted pyrrolidines, piperidines, or azasugars and on the other side by phenylalanine, tyrosine, or substituted tyrosines. The libraries are synthesized via a one step coupling reaction. Highly efficacious drug candidates are identified by screening the libraries for binding and inhibitory activity against both HIV and FIV protease. Drug candidates displaying clinically useful activity against both HIV and FIV protease are identified as being potentially resistive against a loss of inhibitory activity due to development of resistant strains of HIV.

Efficient and industrially applicable synthetic processes for precursors of HIV protease inhibitors (Amprenavir, Fosamprenavir) are described. These involve a novel and economical method for the preparation of a key intermediate, (3S)-hydroxytetrahydrofuran, from L-malic acid. Three new approaches to the assembly of Amprenavir are also discussed. Of these, a synthetic route in which an (S)-tetrahydrofuranyloxy carbonyl is attached to L-phenylalanine appears to be the most promising manufacturing process, in that it offers satisfactory stereoselectivity in fewer steps.
