Sepased, an enzyme for resolving the cohesion of Chromatide Sister, is an oncogene and overexpressed in many human cancer. SEPIN-1 (2,2-dimethyl-5-nitro-2h-benzimidazole-1,3-dioxide) is a powerful sepaase inhibitor that prevents the growth of cancer cells, cell migration and wound healing suggesting that Epin -1 has a great potential to target tumors on the sepaase overexpension. As part of the ind-activatable studies to bring Send-1 to the clinic, we report here the results of a repeated dose pharmacokinetic study of 28 days in rats. Sepin-1 was administered intravenously to Sprague-Dawley rats once a day for 28 days at three different doses (5, 10 and 20 mg / kg).
The blood samples were collected after the dose administration on days 1 and 28. Sepin-1 is unstable in a basic pH phosphate buffered saline solution in an acid buffer such as citrate buffered saline (pH 4.0). The indicated UHPLC-MS analysis was quickly metabolized in vivo. One of the major metabolites was a 2,2-dimethyl-5-nitro-2h-benzimidazole amine adduct (named 655). The concentration of high-1.55 in blood samples was dependent on the dose grade-1 and used for the pharmacokinetic analysis of the sepin-1. Tmax was about 5 to 15 minutes. The data suggest that no completed accumulation-1 has occurred repeated daily dosage and similar exhibitions on the first and last day of assay. The data also suggest a gender difference, namely that female rats have more exposure and clearance slower than male rats.
The data carrier that Fepin-1 is a potential drug candidate that can also be developed to treat overexpressive human tumors separated. Chromosomal segregation begins when the protease of cysteine, separated, clear the SCC1 subunit of the cohesin to the transition of metaphase-anapase. Sepase is inhibited before the metaphase by the tightly linked secure protein, which contains a pseudosubstrate pattern that blocks the active site separated. To study the specificity and regulation of the sepaase substrate, we are developing a recombinant and safe human separation production system. Using this enzyme, we identify a LPE pattern on the separate SCC1 substrate from the cleavage site and is required for quick and specific substrate cleavage.
Toxicity study on the sepaase-sepin-1 inhibitor in Sprague-Dawley rats.
Sepin-1 is a small compound that inhibits the enzymatic activity of separation and growth of cancer cells. As part of the ind-activatable studies to develop Sepin-1 as a chemotherapeutic agent, we have profiled the toxicity of spin-1 in Sprague-Dawley rats in a good laboratory practice (GLP). The maximum tolerated dose (MTD) of Sepin-1 in rats is 40 mg / kg in a single dose study and 20 mg / kg in the studied study for 7 consecutive days. The toxicity study consists of two main study and recovery study. Sepin-1 with 0 (control), 5 (low dose), 10 (median dose) and 20 (high dose) mg / kg were administered by an intravenous injection of bolus to rats once a day for 28 consecutive days.
The animals of the main study were euthanized on day 29, while the animals of the recovery study were allowed to recover for 28 days after the 28-day sepin-1 dose before being euthanized on the day 29 of the period out of dose. Although the effects of the final and median doses are minimal, a hematological analysis shows that the dose of the high dose is associated with a decrease in red blood cells and hemoglobin, and increases the number of reticulocytes. and platelets as well as average corpuscular volume. Clinical chemistry indicates that Fepin-1 causes an increase in total bilirubin and a decrease in Kinase creatine. Histopathology analysis indicates that the minimum bone bone bone hyperplasia is hyperplasia, minimal minimal splenic extramary hematoposis, minimal splenic lymphoid exhaustion, minimum thymic lymphoid exhaustion to light minimal lymphatic hyperplasia. minimal at minimal and light lymphoid hyperplasia in male and female rats in the main study.
These abnormal changes are dependent on the dose-1 and especially reversible after a 28-day recovery period in the animals of the recovery study. On the basis of our results, we conclude that Pharmacological Doses Sein-1 (5-10 mg / kg) is well-tolerable, without significant mortality or morbidity, and can be further developed as a new potential drug to treat The sepaase-overexpressed tumors.
Stability and pharmacokinetics of separase inhibitor-sepin-1 in sprague-dawley rats.
The coinin subunit variant is identified from the peripheral sclerocornea genealogy.
ScleroCornea is a defiant disturbance that is rarely marked by the turbidity of the cornea. Here, we reported the Chinese family of nonkonsanguineous with some peripheral sclerocornea patients which stretched in three generations inherited in the dominant way of autosomes. This is a retrospective case series from the peripheral sclerocornea genealogy. A comprehensive ophthalmic examination was conducted and assessed in 14 pedigree members. All exome sequencing is used to identify genetic changes in members of the affected genealogy. LimfoBlastoid Cell Line (LCLS) was established using blood samples from family members. Functional tests are carried out with this cell line.
Results
Six affected and eight family members who were not affected by Peripheral Sclerocorno were examined. All affected individuals show Sclerazation features over peripheral cornea from both eyes. Means that the diameter of horizontal and vertical cornea is found significantly decreasing in the affected members. The significant difference was also observed in the average Pachymetry Apex between subjects affected and not affected. This ophthalmic parameter does not resemble Cornea Panaa. The RAD21C1348T variant is identified with the sequencing throughout the exome. Although this variant caused the substitution of RAD21 R450C on Sepeanase cleavage sites, cells from members of the ScleroCornea family did not have mitosis and ploidy defects.

Conclusion
We reported a peripheral sclerocorno family without connection with Cornea Plana. RAD21 variant found cosegregating with peripheral sclerocornea. Our results show that the RAD21 function, in addition to the cell cycle and the regulation of chromosome separation, can underline the peripheral catocornea pathogenesis.
