Molecular characterization of the phenolic acid metabolism in the lactic acid bacteria Lactobacillus plantarum
2001
The lactic acid bacteria Lactobacillus plantarumdisplays substrate-inducible decar- boxylase activities on p-coumaric, caffeic and ferulic acids. Purification of the p-coumaric acid decarboxylase (PDC) was performed. Sequence of the N-terminal part of the PDC led to the cloning of the corresponding pdc gene. Expression of this gene in Escherichia colirevealed that PDC displayed a weak activity on ferulic acid, detectable in vitro in the presence of ammonium sulfate. Transcrip- tional studies of this gene in L. plantarum demonstrated that the pdc transcription is phenolic acid- dependent. A mutant deficient in the PDC activity, designated LPD1, was constructed to study phe- nolic acid altern…
Anticancer Activity of Salvia miltiorrhiza and Its Secondary Metabolites
2017
Salvia miltiorrhiza Bunge (danshen) is a well-known traditional Chinese medicinal herb. The root part of the plant contains most of the bioactive ingredients, which mainly belong to two groups of compounds: hydrophilic phenolic acids and hydrophobic tanshinones. These bioactive compounds refer to as secondary metabolites and exert multiple therapeutic activities, such as anti-oxidative stress, anti-neurodegenerative, anti-inflammatory, and anti-hypertensive effects without showing serious side effects. Besides these pharmacological activities, anticancer effects have also attracted scientific attention. This review will provide an updated summary of the anticancer effects and the proposed m…
Randomised trial of mycophenolate mofetil versus azathioprine for treatment of chronic active Crohn’s disease
1999
BACKGROUNDCrohn’s disease is a chronic inflammatory disease of the alimentary tract. Azathioprine is an effective agent in the management of chronic active Crohn’s disease leading to long term remission of disease activity. Such treatment leads to limited efficacy or side effects in a small subset of patients.AIMSTo compare efficacy and side effects of treatment with azathioprine plus corticosteroids versus mycophenolate mofetil (MMF) plus corticosteroids in patients with chronic active Crohn’s disease.METHODSSeventy patients with chronic active Crohn’s disease (Crohn’s disease activity index (CDAI) greater than 150) were randomised for treatment with azathioprine/cortisone or MMF/cortisone…
Mycophenolate mofetil and enteric-coated mycophenolate sodium in the treatment of pemphigus vulgaris and pemphigus foliaceus.
2014
What is known and objective: Pemphigus is a severe, potentially life-threatening autoimmune blistering disease. The use of corticosteroids has dramatically improved the prognosis and changed its course. However, current morbidity of pemphigus is largely iatrogenic, caused by side effects of the long-term, high-dose corticosteroid therapy that is necessary to sustain disease control. In order to minimize side effects, a range of corticosteroid-sparing immunosuppressive agents have been introduced, including mycophenolate mofetil (MMF) and enteric-coated mycophenolate sodium (EC-MPS). A systematic review was performed to evaluate the effectiveness of MMF and EC-MPS in the treatment of pemphig…
Treatment of relapsing idiopathic nodular panniculitis (Pfeifer-Weber-Christian disease) with mycophenolate mofetil
1998
Idiopathic nodular panniculitis (Pfeifer-WeberChristian disease) is characterized by fever and symmetric subcutaneous nodules often located on the lower extremities.1,2 Histologically, a lobular panniculitis with a pronounced neutrophilic infiltrate is observed. The course of the disease is characterized by acute onset with fever and malaise and the simultaneous appearance of painful subcutaneous nodules. Some patients experience involvement of the intra-abdominal or retroperitoneal fat. Relapses are frequent, and a fatal outcome has been described repeatedly. Therapy usually consists of steroids in medium to high dosages, as well as immunosuppressive drugs such as azathioprine or methotrex…
Pharmacokinetic evaluation of mycophenolate mofetil for pemphigus.
2011
Introduction: Pemphigus is an autoimmune blistering disease of the skin and mucous membranes characterized by the development of autoantibodies against the desmosomal proteins, desmoglein-1 and -3. Before the advent of corticosteroids, therapy was almost fatal. The introduction of high-dose corticosteroid therapy has reduced mortality rates to similar to 10%, but long-term use of steroids can lead to side effects, many of which are severe and associated with significant morbidity. Thus, the major goal of pemphigus therapy has been to reduce the patient's cumulative exposure to systemic corticosteroids. Over the last 2 decades, a range of corticosteroid-sparing immunosuppressive agents have …
