In Vitro Studies on Physiological and Chemical Stability of New LE404-Derivatives with Extended Half-Life

Drug Research, 2018
AbstractDibenzoazecines are a class of potential neuroleptics with high affinity to dopamine and serotonin receptors. The efficacy and high therapeutic range has already been demonstrated in vivo with the lead structure 7-methyl-5,6,7,8,9,14-hexahydrodibenzo[d,g]azecin-3-ol (LE404) and selected derivatives.

Comparison of rate of Hepatic Metabolismin vitroand Half-Life for Antipyrinein vivoin Three Species

Xenobiotica, 1979
1. A radiometric assay for the total metabolism of antipyrine in vitro by hepatic microsomal preparations has been developed. 2. Apparent Km and V values for the process were determined in rats, rabbits and in a marsupial (the quokka; Setomix brachyurus).

Effect of different conformations of galactose messenger RNA on gene expression and messenger half-life in vitro

Molecular and General Genetics MGG, 1975
From a DNA-directed cell-free system, functional gal mRNA is obtained which directs the cell-free synthesis of the three galactose enzymes of Escherichia coli. A substantial fraction of this gal mRNA has the properties of a polycistronic messenger.

In Vitro Effects of Cellular Phone Electromagnetic Fields at 940 MHz on the Structure and Half-Life of Recombinant Human Growth Hormone

Iranian Journal of Science and Technology, Transactions A: Science, 2020
The biological effects of non-ionizing electromagnetic radiation (EMF) are of high importance in biological and health studies. This study aimed to find out these effects on the structure and function of recombinant human growth hormone (rhGH). The rhGH was exposed to uniform mobile phone 940-MHz EMFs for 45 min and then characterized by circular ...

In vitro half-life of 14-C-tryptamine in whole blood of drug-free chronic schizophrenic patients

American Journal of Psychiatry, 1977
The authors found higher in vitro 14C-tryptamine half-lives in the blood of 10 drug-free chronic schizophrenic patients than in the blood of 13 mentally normal control subjects. This finding was negatively correlated for both groups with platelet MAO activity.

In vitrodigestion kinetics of excipients for lipid-based drug delivery and introduction of a relative lipolysis half life

Drug Development and Industrial Pharmacy, 2011
Lipid-based drug delivery systems are widely used for enhancing the solubility of poorly water soluble drugs in the gastro-intestinal tract. Following oral intake, lipid systems undergo digestion in the stomach as well as the intestine. Lipolysis is here a complex process at the oil/water interface, influenced by numerous factors.To study the ...

In vitro combined haemostatic efficacy of emicizumab and extended half‐life factor VIII compounds

Haemophilia
Abstract Introduction Early prophylaxis is the gold standard of care for severe haemophilia. The development of subcutaneous Factor VIII (FVIII) mimetics, such as emicizumab, has significantly reduced the disease burden and improved protection against bleeding episodes.

Pseudomonas aeruginosa Recombinant L-asparaginase: PEGylation with Low Molecular Weight Polyethylene Glycol, Molecular Dynamics Simulation, In vitro and In vivo Serum half-life and Biochemical Characterization

Current Pharmaceutical Biotechnology
Background: Microbial L-asparaginase (L-ASNase, EC 3.5.1.1) is a pivotal biopharmaceutical drug-protein that catalyzes the hydrolysis of the non-essential amino acid L-asparagine (L-Asn) into L-aspartic acid (L-Asp) and ammonia , resulting in deplenishing the cellular L-Asn pool, which leads to the ultimate death of the L-asparagine synthetase (L-ASNS)

Effect of whole-body irradiation on the half-life of antipyrine and on the microsomal enzyme system of rats. Correlation between in vivo and in vitro results.

Enzyme, 1983
An increase in half-life of antipyrine and a decrease in the metabolic capacity of microsomes were observed in rats 4 and 6 days after the in vivo gamma-irradiation. A correlation was noted between the in vivo half-life of antipyrine and the in vitro microsomal data.
