Novel oxadiazole compounds, pharmaceutical compositions containing such compounds and the use of those compounds or compositions as agonists or antagonists of the S1P family of G protein-coupled receptors for treating diseases associated with modulation of S1P family receptor activity, in particular by affording a beneficial immunosuppressive effect are disclosed.
The first series of lanthanide amido complexes incorporating a neutral pyrrole ligand in a constrained geometry architecture were synthesized, and their bonding, reactions, and catalytic activities were studied. Treatment of [(Me3Si)2N]3Ln(μ-Cl)Li(THF)3 with 1 equiv of (N-C6H5NHCH2CH2)(2,5-Me2C4H2N) (1) afforded the first example of bisamido lanthanide complexes having the neutral pyrrole η5-bonded

A series of conformationallyconstrained 3-(N-alkylamino)propylphosphonic acids were systematically synthesized and their activities as S1P receptoragonists were evaluated. Several pyrrolidine and cyclohexane analogs had S1P receptor profiles comparable to the acyclic lead compound, 3-(N-tetradecylamino)propylphosphonic acid (3), lowered circulating lymphocytes in mice after iv administration and

The present invention relates to Amido-Substituted Pyridotriazine Derivatives of Formula (I): (I) and pharmaceutically acceptable salts thereof, wherein B, X, Y, R, R1, R2 and R10 are as defined herein. The present invention also relates to compositions comprising at least one Amido-Substituted Pyridotriazine Derivative, and methods of using the Amido-Substituted Pyridotriazine Derivatives for treating or preventing HIV infection in a subject.
A catalytic amount of trimethylsilyl triflate (TMSOTf) remarkably facilitates the selectiveconjugateaddition of a variety of silyl phosphites, prepared in situ from dialkyl phosphites and N,O-bis(trimethylsilyl)acetamide, to cyclic enones giving 1,4-adducts in high yields.
