The importance of the structure similarity of drugs used for depression and inflammation, two comorbid diseases.
Abstract Growing evidence links inflammation to depression and the combination of anti-inflammatory drugs with antidepressant to treat depressive symptoms is currently suggested. There is only few studies concerning the molecular mechanism underlying this comorbidity and many of them point out the importance of the tryptophan pathway. There is yet no data that analyzes the structural similarity of the molecules used for the treatment of these comorbid diseases. This review aimed first to classify current antidepressant drugs and non-steroidal anti-inflammatory drugs (NSAIDs) according to their structure. Molecules...

Determining the Molecular Pathways Underlying the Protective Effect of Non-Steroidal Anti-Inflammatory Drugs for Alzheimer's Disease: A Bioinformatics Approach
In this study, we use pathway enrichment and fuzzy logic to identify pathways (KEGG database) simultaneously affected in both AD and by NSAIDs (Sulindac, Piroxicam, Paracetamol, Naproxen, Nabumetone, Ketoprofen, Diclofenac and Aspirin). Gene expression signatures were derived for disease from both blood (n = 344) and post-mortem brain (n = 690), and for drugs from immortalised human cell lines exposed to drugs of interest as part of the Connectivity Map platform. Using this novel approach to combine datasets we find striking overlap between AD gene expression in blood and NSAID induced changes in KEGG p...

Thiodipeptides targeting the intestinal oligopeptide transporter as a general approach to improving oral drug delivery.
Abstract The broad substrate capacity of the intestinal oligopeptide transporter, PepT1, has made it a key target of research into drug delivery. Whilst the substrate capacity of this transporter is broad, studies have largely been limited to small peptides and peptide-like drugs. Here, we demonstrate for the first time that a diverse range of drugs can be targeted towards transport by PepT1 using a hydrolysis resistant carrier. Eleven prodrugs were synthesized by conjugating modified dipeptides containing a thioamide bond to the approved drugs ibuprofen, gabapentin, propofol, aspirin, acyclovir, nabumetone, ateno...

Coxibs Refocus Attention on the Cardiovascular Risks of Non-Aspirin NSAIDs
This article explains how coxibs refocused attention on the cardiovascular safety of NSAIDs and the general implications of that. COX-2 activity/specificity is one factor associated with increased cardiovascular risks; however, these risks cannot be attributed to coxibs alone. The traditional NSAIDs (i.e., meloxicam, etodolac, and nabumetone) have significant COX-2 specificity, but naproxen and ibuprofen have less specificity. All NSAIDs, whether traditional or a coxib, pose some cardiovascular risks. It is possible that clinicians continue to focus more on decreasing the immediate gastric risks than preventing the later c...

Single dose oral analgesics for acute postoperative pain in adults - an overview of Cochrane reviews.
CONCLUSIONS: There is a wealth of reliable evidence on the analgesic efficacy of single dose oral analgesics. Fast acting formulations and fixed dose combinations of analgesics can produce good and often long-lasting analgesia at relatively low doses. There is also important information on drugs for which there are no data, inadequate data, or where results are unreliable due to susceptibility to publication bias. This should inform choices by professionals and consumers. PMID: 26414123 [PubMed - as supplied by publisher] (Source: Cochrane Database of Systematic Reviews)

Reductive metabolism of nabumetone by human liver microsomal and cytosolic fractions: exploratory prediction using inhibitors and substrates as marker probes
Abstract The metabolic reduction of nabumetone was examined by inhibition and correlation studies using human liver microsomes and cytosol. This reduction was observed in both fractions, with the V max values for reduction activity being approximately fourfold higher, and the V max /K m values approximately three-fold higher, in the microsomes than in the cytosol. The reduction of nabumetone was inhibited by 18β-glycyrrhetinic acid, an 11β-hydroxysteroid dehydrogenase (11β-HSD) inhibitor, in the microsomal fraction. The reduction activity was also inhibit...

A diclofenac suppository–nabumetone combination therapy for arthritic pain relief and a monitoring method for the diclofenac binding capacity of HSA site II in rheumatoid arthritis
ABSTRACT Diclofenac suppository , a non‐steroidal anti‐inflammatory drug (NSAID), is used widely in rheumatoid arthritis (RA) patients with severe arthritic pain. As the binding percentage of diclofenac to serum proteins is high, its free (unbound) concentration after rectal administration is low. To increase temporarily the free concentration of diclofenac and to enhance its analgesic effect by inhibiting the protein binding of diclofenac, the analgesic effect of diclofenac was examined before and after the start of an inhibitor administration to RA patients with insufficient control of arthritic pain, and the protein...
