1. We have examined the effects of tolmetin and meclofenamate on isolated human PMN functions under FMLP stimulating conditions. 2. In a dose dependent manner, tolmetin and meclofenamate inhibited all PMN functions, except that tolmetin stimulated PMN chemotaxis. 3. Meclofenamate was much more

Three new coumarin derivatives, 8-formylalloxanthoxyletin (1), avicennone (2), and (Z)-avicennone (3), have been isolated from the stem bark of Zanthoxylum avicennae (Z. avicennae), together with 15 known compounds (4-18). The structures of these new compounds were determined through spectroscopic

Cancer immunotherapy using chimeric antigen receptor-armed T (CAR T) cells have been shown to improve outcomes significantly in patients with hematological malignancies. However, cytokine release syndrome (CRS) remains a risk. CRS is characterized by the excessive activation of CAR T cells and

Because a general study of activated neutrophils may have relevance to periodontal diseases and accompanying inflammation, we studied a function of mouse polymorphonuclear leukocytes (PMNs) that exude into the peritoneal cavity in response to inflammation caused by i.p. injection of 2% casein. The

A series of indeno[1,2-c]quinoline derivatives were designed, synthesized and evaluated for their anti-tuberculosis (anti-TB) and anti-inflammatory activities. The minimum inhibitory concentration (MIC) of the newly synthesized compound was tested against Mycobacterium tuberculosis H37RV. Among the

Given the proposed involvement of VLA-4 in inflammatory processes, a program to identify orally active VLA-4 antagonists was initiated. Herein, we report the discovery of a N-tetrahydrofuroyl-(L)-phenylalanine derivative (17) and related analogues as potent VLA-4 antagonists with good oral

Galectins are a family of animal lectins defined by their beta-galactoside-binding activities and a consensus sequence in their carbohydrate-recognizing domain (CRD). Relevant roles of galectins are described in adaptive immune response, innate immunity and modulation of the acute inflammatory

The application of 123I-3-iodo-alpha-methyltyrosine is limited to diagnosis of brain tumors due to its marked long-term uptake in kidneys. In vitro evaluation of 125I-2-iodo-L-phenylalanine showed high uptake in R1M cells by L-type amino acid transport system 1 (LAT1). This study evaluates

N-tosyl-l-phenylalanine chloromethyl ketone (TPCK) is known to inhibit NF-kappaB activation and the expression of inflammation mediators in cultured cells. We measured the potential of TPCK to inhibit the pathogenesis of collagen-induced arthritis by blocking NF-kappaB activation. Arthritis was

Human polymorphonuclear leukocytes (PMN) hydrolyze the synthetic chemoattractant N-formyl-L-methionyl-L-leucyl-L-phenylalanine (fMet-Leu-Phe) at nanomolar concentrations in an autocatalytic-like manner that deviates from classical Michaelis-Menten kinetics [Yuli, I. & Snyderman, R. (1986) J. Biol.

Circulating neutrophils were investigated in 15 patients with Crohn's disease (CD), 15 with ulcerative colitis (UC), and 15 healthy volunteers. Dose-response curves for chemotaxis in Boyden chambers were analysed for sensitivity to leukotriene B4 (LTB4), its 20-hydroxy-LTB4 (20-OH-LTB4) and

OBJECTIVE We investigated the effect of a novel N-benzoyl-L-phenylalanine derivative compound (JTE-607) on production of various cytokines and other immune responses in vitro and on endotoxin shock in vivo. METHODS Human, monkey, rabbit, mouse and rat peripheral blood mononuclear cells (PBMCs), and

OBJECTIVE (18)F-FDG-PET is used worldwide for oncology patients. However, we sometimes encounter false positive cases of (18)F-FDG PET, such as moderate uptake in the inflammatory lesion, because (18)F-FDG accumulates not only in the cancer cells but also in the inflammatory cells (macrophage,
