Stereoselective [2,3]-Wittig rearrangement of (1S,2R)-1-amino-indan-2-ol derived amide enolates

An efficient, diastereoselective [2,3]-Wittig rearrangement of alpha-allyloxyamide enolates has been developed using (1S,2R)-1-amino-indan-2-ol as a chiral auxiliary. After auxiliary removal, the resultant optically active a-hydroxy acids have been transformed to functionalized amino acid derivatives.

Design, synthesis, and structure-activity relationships of macrocyclic hydroxamic acids that inhibit tumor necrosis factor alpha release in vitro and in vivo

To search for TNF-alpha (tumor necrosis factor alpha) converting enzyme (TACE) inhibitors, we designed a new class of macrocyclic hydroxamic acids by linking the P1 and P2? residues of acyclic anti-succinate-based hydroxamic acids. A variety of residues including amide, carbamate, alkyl, sulfonamido, Boc-amino, and amino were found to be suitable P1 P1-P2? linkers. With an N-methylamide at P3?, the 13-16-membered macrocycles prepared exhibited low micromolar activities in the inhibition of TNF-alpha release from LPS-stimulated human whole blood. Further elaboration in the P3?-P4? area using the cyclophane and cyclic carbamate templates led to the identification of a number of potent analogues with IC50 values of ?0.2 muM in whole blood assay (WBA). Although the P3? area can accommodate a broad array of structurally diversified functional groups including polar residues, hydrophobic residues, and amino and carboxylic acid moieties, in both the cyclophane series and the cyclic carbamate series, a glycine residue at P3? was identified as a critical structural component to achieve both good in vitro potency and good oral activity. With a glycine residue at P3?, an N-methylamide at P4? provided the best cyclophane analogue, SL422 (WBA IC50 = 0.22 muM, LPS-mouse ED50 = 15 mg/kg, po), whereas a morpholinylamide at P4? afforded the most potent and most orally active cyclic carbamate analogue, SP057 (WBAIC50 = 0.067 muM, LPS-mouse ED50 = 2.3 mg/kg, po). Further profiling for SL422 and SP057 showed that these macrocyclic compounds are potent TACE inhibitors, with Ki values of 12 and 4.2 nM in the porcine TACE assay, and are broad-spectrum MMP inhibitors. Pharmacokinetic studies in beagle dogs revealed that SL422 and SP057 are orally bioavailable, with oral bioavailabilities of 11% and 23%, respectively.

Design, synthesis and trypanocidal activity of lead compounds based on inhibitors of parasite glycolysis

The glycolytic pathway has been considered a potential drug target against the parasitic protozoan species of Trypanosoma and Leishmania. We report the design and the synthesis of inhibitors targeted against Trypanosoma brucei phosphofructokinase (PFK) and Leishmania mexicana pyruvate kinase (PyK). Stepwise library synthesis and inhibitor design from a rational starting point identified furanose sugar amino amides as a novel class of inhibitors for both enzymes with IC50 values of 23 muM and 26 muM against PFK and PyK, respectively. Trypanocidal activity also showed potency in the low micromolar range and confirms these inhibitors as promising candidates for the development towards the design of anti-trypanosomal drugs.

A mild dihydrobenzooxaphosphole oxazoline/iridium catalytic system for asymmetric hydrogenation of unfunctionalized dialins

Air-stable P-chiral dihydrobenzooxaphosphole oxazoline ligands were designed and synthesized. When they were used in the iridium-catalyzed asymmetric hydrogenation of unfunctionalized 1-aryl-3,4-dihydronaphthalenes under one atmosphere pressure of H2, up to 99:1 e.r. was obtained. High enantioselectivities were also observed in the reduction of the exocyclic imine derivatives of 1-tetralones.

Matrix metalloproteinase inhibitors: A structure-activity study

Modifications around the dipeptide-mimetic core of a hydroxamic acid based matrix metalloproteinase inhibitor were studied. These variations incorporated a variety of natural, unnatural, and synthetic amino acids inaddition to modifications of the P1′ and P3′ substituents. The results of this study indicate the following structural requirements: (2) Potent inhibitorsmust possess string zinc-binding functionalities. (3) The potential importance of the hydrophobic group at position R3 as illustratedby itsability to impart greater relative potency against stromelysin when larger hydrophobic groups are used. (4) Requirements surrounding the nature of the amino acid appear to be more restrictive for stromelysin than for neutrophil collagenase, 72 kDa gelatinase, and 92 kDa gelatinase. These requirements may involve planar fused-ring aryl systems and possibly hydrogen-bonding capabilities.

Synthesis and structural study of the enantiomers of alpha, alpha?-bis(trifluoromethyl)-10,10?-(9,9?-bianthryl) dimethanol as a chiral solvating agent

We describe the synthesis, the structure, and the behavior as a chiral solvating agent of the enantiomers of alpha,alpha?- bis(trifluoromethyl)-10,10?-(9,9?-biantryl)dimethanol. The thermodynamics of several associations are presented. We conclude that the association needs the approximation of the aromatic systems and that the geometry of complexation is the main factor that defines the enantiodiscrimination.
