Specific pathways of potential importance for drug metabolism and elimination can be explored using well-defined drug-metabolizing enzyme systems (11, 12). When coupled with sensitive qualitative analytical methods, such studies can identify metabolites that may be searched for in vivo. Furthermore...
Intrinsic clearance in vitro (Clint in vitro) can be calculated according to the equation: Clint in vitro= kV/N, where k = 0.693/t1/2, V = incubation volume (1 mL) and N = number of hepatocytes per well (0.5 x 106viable cells). ...
While functional effects such as the ion-channel assays are important, adverse structural effects can also be critically detrimental. A recent in vitro assay using cardiomyocytes derived from stem cells is claimed to be capable of assessing both structural and functional damage in the same assay, pr...
In vitro screening techniques for reactive metabolites for minimizing bioactivation potential in drug discovery. Drug induced toxicity remains one of the major reasons for failures of new pharmaceuticals, and for the withdrawal of approved drugs from the market. Effor... C Prakash,R Sharma,M Gleave...

Gut microbiota (GM) plays many key functions and helps maintain the host’s health. Consequently, the development of GM cultivation under in vitro stimulating physiological conditions has gained extreme interest in different fields. In this study, we eva
Overall, antioxidant capacity of A. crispa was considered high. HEAC, EAEAC and AQEAC showed good scavenging activities, able to scavenge at least 50% of free radicals solution below than 10 mg/mL of extract concentration. Table 2 DPPH scavenging assay of A. crispa leaves from different ...
In Vitro ADME Assays In Vitro ADME assay is an essential step in drug development. We will help you to understand the Adsorption, Distribution, Metabolism, Excretion (ADME) as well as the Pharmacokinetics (PK) of your compounds, which will help both your
2.6. Cell migration assay The effect of essential oils extract on the migration of MIA PaCa-2 cells was studied by the wound healing assay as previously described.18 MIA PaCa-2 cells were seeded separately in 6-well plate and incubated for 48 h to achieve almost 100% confluent monolayer. ...
In vitro cultivation of Cystoisospora suis can be used to assay drug efficacy. • Quantification is best achieved by real-time PCR in comparison to a plasmid standard. • Efficacy of toltrazuril and its metabolites in vitro is not strictly dose-dependent. ...
