cellulose‐based chiralstationaryphase were achieved particularly with propane‐2‐ol and a mixture of isopropylamine and trifluoroacetic acid as organic modifier and additive to CO2, respectively. Methanol and basic additive isopropylamine were preferred on amylose‐based chiralstationaryphase. The complementary enantioselectivity of the cellulose‐ and amylose‐based chiralstationaryphases allows separation
The instant invention provides compounds of Formula I which are leukotriene biosynthesis inhibitors.
Compounds of Formula I are useful as anti-atherosclerotic, anti-asthmatic, anti-allergic, anti-inflammatory and cytoprotective agents.

Potent ligands for the human complement C3a receptor (C3aR) were developed from the almost inactive tripeptide Leu-Ala-Arg corresponding to the three C-terminal residues of the endogenous peptide agonist C3a. The analogous Leu-Ser-Arg was modified by condensing the serine side chain with the leucine carbonyl with elimination of water to form leucine-oxazole-arginine. Subsequent elaboration with a variety
Colistin Sulfate Chiral Stationary Phase for the Enantioselective Separation of Pharmaceuticals Using Organic Polymer Monolithic Capillary Chromatography
and antiarrhythmic drugs. Acceptable separation was achieved for many drugs using reversed phase chromatographic conditions with no separation achieved under normal phase conditions. Colistin sulfate appears to be useful addition to the available macrocyclic antibiotic chiralphases used in liquid chromatography.
