New drugs approved by the U.S. FDA (2007-2016): A review / 国际药学研究杂志

The introductions of the new drugs approved by the U.S. FDA have been published in the“ Journal of International Pharmaceutical Research ”for ten years. However, new problems might emerge with the increasing clinical practice and the cumulative number of patients being treated, such as the indications and purposes change, supplement of the modified efficacy, clinical data and the important new indications, constant improvement of the dosage, form and mode of administration, and the emergence of new, serious and even fatal adverse reactions urge the supplements of contraindications, warnings and precautions, or even the black box warnings. In brief, 6 entries of the introductions all may be modified, supplemented or canceled.

Studies on the pharmacokinetics of lidamycin in mice and dogs using bioassay / 药学学报

<p><b>AIM</b>A bioassay method was established for the determination of active concentrations of lidamycin and studied its pharmacokinetics in mice and dogs.</p><p><b>METHODS</b>Cytotoxicity of lidamycin in vitro was used to determine drug serum concentrations in vivo.</p><p><b>RESULTS</b>Validity of methodology met the requirements of pharmacokinetic study. The concentration-time profile in mice after iv lidamycin of 100, 50 and 10 microg x kg(-1) was best fitted with 2-compartmental model with T1/2alpha and T1/2beta of 0.77-1.8 min and 5.6-7.2 min, respectively. The AUC were 2851.3, 887.8 and 166.4 microg x min x L(-1), respectively and increased with dose nonlinearly. There were similar trends between AUC and the potency of tumor growth inhibition. After iv lidamycin of 12 microg x kg(-1) in dogs, the concentrations of lidamycin decreased rapidly and the AUC was 16 microg x min x L(-1), which were lower and quicker than those in mice. The levels in serum after second administration at day 15, were lower than those of the first.</p><p><b>CONCLUSION</b>Active concentrations and pharmacokinetics of lidamycin were obtained by bioassay method successfully. There are species differences and single and multi-dosing differences in the pharmacokinetics of lidamycin.</p>

Metabolism, Distribution and Excretion of Recombinant Human Thrombopoietin in Mice / 中国实验血液学杂志

The metabolism, distribution and excretion profiles of recombinant human thrombopoietin (rhTPO) in mice were studied by means of (125)I-labeled rhTPO ((125)I-rhTPO) combined with size exclusive high performance liquid chromatography (SHPLC) or trichloroacetic acid (TCA) precipitation analysis. (125)I-rhTPO was prepared by iodogen method. Purification was performed on Sephacryl S-200 HR gel. Radioactive-purity of (125)I-rhTPO identified by SHPLC was (96.9 +/- 1.5)% (n = 3). The proliferation effect of TPO dependent cell line (TD-3) and the increase of peripheral platelet counts in mouse by (125)I-rhTPO demonstrated that (125)I-labeled protein maintained the biological activities of TPO both in vitro and in vivo. SHPLC analysis of serum and urine samples taken after sc 1 micro g/mouse (345 kBq/mouse) of (125)I-rhTPO revealed that there were two lower molecular weight (125)I-degradation metabolites ((125)I-MI and (125)I-MII) other than parent molecule. (125)I-MI was mainly found in urine, and (125)I-MII was detected both in serum and in urine. The maximal concentration of (125)I-rhTPO was reached at 2 hours after injection. The terminal half-life was 10.8 hours, which was much longer than those of other peptides. TCA precipitable radioactivity in tissue showed that the radioactivity in bone marrow was rather high. The highest level was found in urinary system. Levels in adrenals, lymph nodes, and fat were near to that in serum. Lowest was found in brain. The main excretion route was urinary system and (98 +/- 5.6)% of (125)I-rhTPO was excreted within 72 hours after dosing.
