In-vitro Metabolic Interaction of Bunitrolol Enantiomers in Rabbit Liver MicrosomesJournal of Pharmacy and Pharmacology - Tập 48 Số 11 - Trang 1185-1189 - 2011

Abstract We have examined the 4-hydroxylation of bunitrolol in rabbit and rat
liver microsomes. Significant species differences (rabbit < rat of both
sexes) and sex (male > female of both species) were observed in the formation
of 4-hydroxybunitrolol from racemic bunitrolol (10 μM). The 4-hydroxylation of
bunitrolol racemate and enantiomers showed biphasic kinetics, a low-Km system
and a hig... hiện toàn bộ
Effect of the Chloroform Extract of Tanacetum vulgare and one of its Active Principles, Parthenolide, on Experimental Gastric Ulcer in RatsJournal of Pharmacy and Pharmacology - Tập 51 Số 2 - Trang 215-219 - 1999
Horacio Tournier, Guillermo Schinella, Elba M De Balsa, H. Buschiazzo, Salvador Máñez, Perla M. de Buschiazzo
Abstract This study examines the anti-ulcerogenic activity of a chloroform
extract of Tanacetum vulgare and purified parthenolide, the major sesquiterpene
lactone found in the extract. Gastric ulcers induced by oral administration of
absolute ethanol to rats were reduced dose-dependently by oral pretreatment of
animals with the chloroform extract (2.5–80 mg kg−1) or parthenolide (5–40
mgkg−1). Whe... hiện toàn bộ
Anti-inflammatory Effects of South American Tanacetum vulgareJournal of Pharmacy and Pharmacology - Tập 50 Số 9 - Trang 1069-1074 - 1998

Abstract In recent years the role of phenolic compounds and sesquiterpene
lactones, particularly parthenolide, in the anti-migraine and anti-inflammatory
effects of Tanacetum parthenium (Asteraceae) has attracted much attention.
However, the closely-related cosmopolitan species T. vulgare has remained
outside the mainstream of research in this field. After treating the aerial
parts of T. vulgare w... hiện toàn bộ
Cyclooxygenase-1 and cyclooxygenase-2 selectivity of non-steroidal anti-inflammatory drugs: investigation using human peripheral monocytesJournal of Pharmacy and Pharmacology - Tập 53 Số 12 - Trang 1679-1685 - 2010
Mototoshi Kato, Shinichi Nishida, Hidero Kitasato, Natsue Sakata, Shinichi Kawai
Abstract Since the pharmacological profiles of various non-steroidal
anti-inflammatory drugs (NSAIDs) might depend on their differing selectivity for
cyclooxygenase 1 (COX-1) and 2 (COX-2), we developed a new screening method
using human peripheral monocytes. Monocytes from healthy volunteers were
separated, and the cells were incubated with or without lipopoly-saccharide
(LPS). Monocytes without ... hiện toàn bộ
Skin Delivery of Oestradiol from Deformable and Traditiona Liposomes: Mechanistic StudiesJournal of Pharmacy and Pharmacology - Tập 51 Số 10 - Trang 1123-1134 - 1999
Gamal M. El Maghraby, Adrian C. Williams, Brian Barry
AbstractDeformable vesicles and traditional liposomes were compared as delivery
systems for oestradiol to elucidate possible mechanisms of drug delivery through
human skin. Accordingly, epidermal permeation of oestradiol from optimized
deformable vesicles and traditional liposome formulations was studied under low
dose non-occluded conditions. Five mechanisms were investigated. A free drug
mechani... hiện toàn bộ
Natural products as targeted modulators of the nuclear factor-κB pathwayJournal of Pharmacy and Pharmacology - Tập 54 Số 4 - Trang 453-472 - 2002
Paul Bremner, Michael Heinrich
Abstract The use of plant extracts to alleviate inflammatory diseases is
centuries old and continues to this day. This review assesses the current
understanding of the use of such plants and natural products isolated from them
in terms of their action against the ubiquitous transcription factor, nuclear
factor kappa B (NF-κB). As an activator of many pro-inflammatory cytokines and
inflammatory pro... hiện toàn bộ
