Cyclopentyl compounds linked to a benzoxazinyl group through an amido moiety utilizing the ring nitrogen of the benzoxazine, and further substituted with a heterocyclic moiety, such compounds represented by formula I:
which are used to modulate the CCR-2 chemokine receptor to prevent or treat inflammatory and immunoregulatory disorders and diseases, allergic diseases, atopic conditions including allergic rhinitis, dermatitis, conjunctivitis, and asthma, as well as autoimmune pathologies such as rheumatoid arthritis and atherosclerosis; and pharmaceutical compositions comprising these compounds and the use of these compounds and compositions.

Compound formula I: wherein: X1 and X2 may be either (a) C and O, (b) N and N, or (c) C and NH, where the dotted bonds represents a double bond in the appropriate location; R1 and R2 are independently selected from hydrogen, an optionally substituted C1-7 alkyl group, an optionally substituted C3-20 heterocyclyl group, or an optionally substituted C5-20 aryl group, or may together form, along with the nitrogen atom to which they are attached, an optionally substituted heterocyclic ring having from 4 to 8 ring atoms; RN1 is selected from hydrogen and an optionally substituted C1-4 alkyl group; RC1 is selected from an optionally substituted C1-7 alkyl group, an optionally substituted C3-20 heterocyclyl group, or an optionally substituted C5-20 aryl group; or RN1 and RC1 may together form an optionally substituted C2-4 alkylene group.
The present invention provides novel N-substituted fluorooxindoles having the general Formula I
wherein the wavy bond
represents the racemate, the (R)-enantiomer or the (S)-enantiomer and m, n, p, q, A, B, D, Q, X, and Z are as defined below, or a nontoxic pharmaceutically acceptable salt or solvate thereof and are useful in the treatment of disorders which are responsive to the opening of potassium channels.
An Efficient Strategy to Orthogonally Protected (<i>R</i>)- and (<i>S</i>)-α-Methyl(alkyl)serine-Containing Peptides via a Novel Azlactone/Oxazoline Interconversion Reaction
for the synthesis of (R)- and (S)-alpha-methyl(alkyl)serine-containing peptides is presented. Using (S)-phenylalanine cyclohexylamide 6 as chiral auxiliary, the optically pure azlactones (R)- and (S)-2 were synthesized via a novel azlactone/oxazoline interconversion reaction (Figures 3 and 6). These azlactones constitute fully protected and activated synthetic equivalents of (R)- and (S)-alpha-methylserine
