BACKGROUND: Inter-individual variability in hepatic drug metabolizing enzyme (DME) activity is a major contributor to heterogeneity in drug clearance and safety. Accurate data on expression levels and activities of DMEs is an important prerequisite for in vitro-in vivo extrapolation and in silico based predictions. Characterization and assessment of inter-correlations of the major DMEs cytochrome P450s (CYPs) and UDP-glucuronosyltransferases (UGTs) have been extensively documented, but simultaneous quantification including other major DMEs has been lacking...

BACKGROUND: Chronic kidney disease (CKD), a global public health problem, affects numerous people worldwide, and the prevalence is rising. Results from animal experiments and clinical investigations have demonstrated that drug metabolic enzymes and transporters-mediated non-renal clearance is dramatically impaired in CKD, co-respondent with the alterations in the elimination of metabolized drugs. Accumulated uremic toxins may downregulate or directly inhibit the activity and/or the expression of drug metabolic enzymes and transporters, which may result in unintended alterations of drug exposure and response in cases when drugs dose are not adjusted for the renal dysfunction...

The calcineurin inhibitor tacrolimus (Tac) is an integral part of the standard immunosuppressive regimen after renal transplantation (RTx). However, clinical management of Tac therapy can be challenging because of its narrow therapeutic window and because many factors interfere with its metabolism. Therefore, therapeutic drug monitoring is used to adjust the dosage. Recently, we were able to classify patients receiving tacrolimus into two major metabolism groups by simple calculation of the C/D ratio (expressed as the blood concentration normalized by the dose)...

Over the past two decades, saccharolactone has been routinely used in in vitro microsomal incubations, and sometimes in incubations with recombinant Uridine diphosphoglucuronosyl transferases (UGT) while investigating glucuronidation reactions. The addition of saccharolactone is aimed at completely inhibiting β-glucuronidases that may be present in the microsomes, in the anticipation of accurate identification and quantification of the formed glucuronide metabolites. Recent research has demonstrated that saccharolatone may not serve the intended objective, and may even lead to inhibition of certain UGTs...

BACKGROUND: The etiopathogenesis of psychiatric disorders is still not completely understood. Growing evidence supports the hypothesis that mental illness and related disturbances in the brain neurobiology do not necessarily originate in the brain. Inflammation has been suggested to play a central role in psychiatric disorders, and altered levels of peripheral cytokines have been reported in several studies. OBJECTIVE AND METHODS: In this review, we present and discuss studies exploring the role of dysbiosis and products of the gut-microbiota in the pathogenesis of psychiatric disorders, as well as its potential involvement in mediating the effect of antidepressants, mood stabilizers, and antipsychotics...

BACKGROUND: Bipolar disorder (BD) is a debilitating mental ailment characterized by recurrent episodes of mania and depression. Primary mood-stabilizing drugs like lithium and valproate alleviate the hypomanic or mild to moderate manic episodes in patients with BD. One of the extensively studied underlying mechanisms for these pharmacological interventions is inhibition of intracellular signaling cascades associated with glycogen synthase kinase-3 beta (GSK-3β), a multi-functional serine-threonine kinase...

Blood platelets are crucial for maintaining hemostasis and several events in the wound-healing. However, platelet up-regulation leads to the development and the complications of several cardiovascular diseases. For the effective management of these complications, several synthetic drugs are in clinical practice such as aspirin and warfarin. since a long time. But some adverse reactions like aspirin resistance and bleed disorders cause patient in compliance and reduce their therapeutic potential. Thus, the search for potent and safer antiplatelet agents is of great interest...

The major limitation in the improving polymeric nanoparticles into an efficient gene/drug delivery carrier is the rapid opsonization, phagocytic uptake by mononuclear phagocyte system and subsequent clearance from the bloodstream. The prolonged circulation time of nanoparticles in the blood is a prerequisite to realizing a controlled and targeted (passive or active targeting) release of the encapsulated gene/drug at the desired site of action. In this review, the factors such as biological barriers and physical barriers including particle size, shape, zeta potential, and hydrophilicity will be discussed, which can cause effects on blood clearance and organ accumulation...
