PURPOSE The authors followed and correlated the physiologic and morphologic changes occurring in experimental autoimmune uveitis (EAU) induced by the peptide G of S-antigen. METHODS EAU was induced in Lewis rats by footpad inoculation of a 13-amino acid synthetic peptide (peptide G) in complete Freund's adjuvant. Electroretinography (ERG) was used to(More)
3-Deazaneplanocin A (DzNep) is a potential epigenetic drug for the treatment of various cancers. DzNep has been reported to deplete histone methylations, including oncogenic EZH2 complex, giving rise to epigenetic modifications that reactivate many silenced tumor suppressors in cancer cells. Despite its promise as an anticancer drug, little is known about(More)
Fingerprint recognition refers to the automated method of verifying a match between two human fingerprints. Fingerprints are one of many forms of biometrics used to identify an individual and verify their identity. The non-changeability of Fingerprints during the human life span and the uniqueness of each individual's fingerprints are the basis for using(More)
3-Deazaneplanocin A (DzNep), a global histone methylation inhibitor, has attracted significant interest in epigenetic research in recent years. The molecular mechanism of action and the cellular off-targets of DzNep, however, are still not well-understood. Our aim was to develop novel DzNep-derived small-molecule probes suitable to be used in live mammalian(More)
Pulmonary microvascular occlusion by abnormally adherent and/or nondeformable sickle red blood cells (SS cells) may contribute to the pathogenesis of acute chest syndrome of sickle cell disease. We hypothesized that regional alveolar hypoxia reduces SS cell deformability and, by causing regional vasoconstriction, slows regional perfusion, facilitating(More)
The key cyclopentenyl intermediate 11b was synthesized in 4 steps from d-ribose in 41% overall yield via an efficient intramolecular Baylis-Hillman reaction. This novel key intermediate can be modified easily and transformed to neplanocin A (1a) and its 3'-epimer (1b).
Mycobacteria harbor two main degradative proteolytic machineries, the caseinolytic protease ClpP1P2 and a proteasome. We recently showed that Bortezomib inhibits ClpP1P2 and exhibits whole cell activity against Mycobacterium tuberculosis. Bortezomib, a dipeptide with a boronic acid warhead, is a human proteasome inhibitor approved for cancer therapy. The(More)
Mycobacterium tuberculosis is responsible for the greatest number of deaths worldwide due to a bacterial agent. We recently identified bortezomib (Velcade; compound 1) as a promising antituberculosis (anti-TB) compound. We showed that compound 1 inhibits the mycobacterial caseinolytic proteases P1 and P2 (ClpP1P2) and exhibits bactericidal activity, and we(More)
Dopamine (DA) protected by an o-nitrobenzyl functionality on its phenolic group was synthesized as a photolabile catecholamine derivative. This compound, o-nitrobenzyl dopamine (NBDA), was more stable than DA in basic solution at pH 8.5 and will not self-polymerize when protected from light. UV irradiation of a methanolic solution of NBDA at 365 nm for 40(More)
