Cannabinoid receptors negatively regulate adenylate cyclase through a pertussis toxin-sensitive GTP-binding protein. In the present studies, signaling via cyclase/cAMP pathway was investigated in murine thymoma-derived T-cell line, EL4.IL-2. Northern analysis of EL4.IL-2 cells identified presence 4-kilobase CB2 but not CB1 receptor-subtype mRNA transcripts. Southern genomic DNA digests for receptor demonstrated identical banding patterns and mouse-derived DNA, both which were dissimilar to...

Double-blind, randomized, placebo and active comparator-controlled, 12-week study conducted at 67 sites in 28 countries. Eligible patients were chronic NSAID users who demonstrated clinical worsening upon withdrawal prestudy NSAIDs.

A facile and efficient Cu(I)-catalyzed cross-coupling method is reported for the preparation of N-alkynyl or N-bromoalkenyl heteroarenes from bromoalkynes. Generally superior yields functional group tolerance were obtained with microwave (MW) irradiation using imidazole, benzimidazole, pyrazole, indazole substrates poly(ethylene glycol) 400 (PEG400) as an additive. We speculate that PEG400 acts both a Cu(I)-stabilizing ligand well phase transfer solvent.

Indoleamine 2,3-dioxygenase (IDO) and tryptophan (TDO) are heme enzymes that catalyze the O2-dependent oxidation of l-tryptophan to N-formyl-kynurenine. Previous proposals for mechanism this reaction have suggested deprotonation indole NH group, either by an active-site base or oxygen bound iron, as initial step. In work, we examined activity 1-Me-l-Trp with three different dioxygenases their site-directed variants. We find, in contrast previous is a substrate dioxygenase enzymes. These...

The kynurenine pathway is the major route of L-tryptophan (L-Trp) catabolism in biology, leading ultimately to formation NAD(+). initial and rate-limiting step involves oxidation L-Trp N-formylkynurenine. This an O2-dependent process catalyzed by indoleamine 2,3-dioxygenase tryptophan 2,3-dioxygenase. More than 60 years after these dioxygenase enzymes were first isolated (Kotake, Y., Masayama, I. (1936) Z. Physiol. Chem. 243, 237-244), mechanism reaction not established. We examined...

Indoleamine 2,3-dioxygenase (IDO) and tryptophan (TDO) are heme-containing enzymes that catalyze the O2-dependent oxidation of l-tryptophan (l-Trp) in biological systems. Although many decades have passed since their discovery, mechanism has not been established. It widely assumed IDO TDO react using same mechanism, although there is no evidence they do. For IDO, a Compound II (ferryl) species accumulates steady state implicated mechanism; TDO, such ever observed. In this paper, we examine...

Amphotericin B is a powerful but toxic drug used against fungal infections and leishmaniases. These diseases would be treated more effectively if non-toxic amphotericin derivatives could produced on large scale at low cost. Genetic manipulation of the producer, Streptomyces nodosus, has previously led to detection partial characterisation 8-deoxyamphotericin B, 16-descarboxyl-16-methyl-amphotericin 15-deoxy-16-descarboxyl-16-methyl-15-oxo-amphotericin 7-oxo-amphotericin pentaene analogues....

Abstract Quantitative structure‐activity relationships are widely used to probe CH bond breakage by quinoprotein enzymes. [1–4] However, we showed recently that p ‐substituted benzylamines poor reactivity probes for the aromatic amine dehydrogenase (AADH) because of a requirement structural change in enzyme‐substrate complex prior breakage. [5] This rearrangement is partially rate limiting, which leads deflated kinetic isotope effects benzylamines. Here report (driving force) studies AADH...
