Disclosed herein are compounds including pharmaceutically acceptable salts, esters, prodrugs, hydrates and tautomers thereof which modulate the interactions of CD-40-CD40L. The compounds are useful for treating, ameliorating or preventing an autoimmune disease, inflammatory disease, or other immune-related disease in a patient in need of treatment.
found to be excellent ligands with Pd(OAc)2 in the palladium-catalyzed air (balloon) oxidation of alcohols in toluene at 80 degrees C. Comparison with structurallyrelatedpyridine ligands revealed that introduction of the 2,3,4,5-tetraphenylphenyl substituent at the 3-position of pyridine ring effectively suppresses the Pd black formation, maintaining the catalytic activity for a long time to give aldehydes

Expedient syntheses of the indole alkaloids alocasin A, scalaridine A, and hyrtinadine A-B are presented. All four natural products contain one or two 5-hydroxyindolyl units. Three palladium catalyzed reactions, an alkyne hydrostannylation, a Kosugi-Migita-Stille cross coupling and a reductive N-heterocyclization are the key steps in the syntheses.

Reversiblechemosensing of hydrosulfide (HS−) in pure water is demonstrated using halogen bonding (XB) fluorescent hosts. The XB receptors exhibit characteristic selective quenching of fluorescence upon binding HS− whereas the hydrogen bonding receptor analogues proved incapable of functioning as chemosensors under aqueous conditions.

donor atom dramatically enhances the anion binding potency of the sigma-hole receptors, most notably for the ChB and XB receptors displaying over thirty-fold and eight-fold increase in chloride anion affinity, respectively, relative to unfluorinated analogues. Linear free energy relationships for a series of ChB based receptors reveal the halide anionrecognition behaviour of the tellurium donor is
