The study shows that keeping rats in different light modes has a different impact on pancreatic and intestine amylase activity and has its peculiarities in regard of age as well as geroprotectors' influence on it. Melatonin use entails pancreatic amy…
The number of hypothalamic IL-2-containing cells changed in rats receiving Vilon and Epithalon during mild stress (handling). The number of IL-2-positive cells in hypothalamic structures decreased 24 h after intramuscular injection of Epithalon and 2…
The effect of synthetic peptide bioregulators (Epitalon, Livagen and Vilon) on structural and facultative heterochromatin of cultivated lymphocytes have been studied among old (75-88yr.) people. The data obtained indicate that epitalon, livagen and v…
The potential preventive effect of the synthetic pineal peptide Epitalon (Ala-Glu-Asp-Gly) on spontaneous tumorigenesis in mice was studied. One-year-old female C3H/He mice were kept for 6.5 months under standard conditions. Epitalon was injected at…
Age-specific characteristics of production of lymphocyte-activating factor by mouse peritoneal macrophages and modulation of this production by short synthetic peptides (Vilon, Epithalon, and Cortagen) were studied. The production of lymphocyte-activ…
Properties of tetrapeptide epitalon (Ala-Glu-Asp-Gly) constructed on the basis of pineal peptide extract, have been studied. The intranasal infusions: a noninvasive way to deliver this peptide to CNS hypassing the blood-brain barrier, was used. The a…
The influence of the chronic administration of melatonin (epiphyseal hormone) and epitalon (a synthetic tetrapeptide increasing melatonin production) on the learning process and the protracted memory has been studied in LIO rats in the course of agin…
Ageing, melatonin, epithalon (tetrapeptide Ala-Glu-Asp-Gly) and different light conditions effects on protein content and cathepsins B and D activities in rat liver and kidneys lysosomal fractions were studied. Ageing leads to decrease of cathepsins…
Theratechnologies, under license from Valeant, is developing tesamorelin as a potential vaccine adjuvant and for the potential treatment of wasting, hip fracture recovery, immune disorders, HIV-related lipodystrophy, sleep maintenance insomnia and mi…
Biologically active peptides evenly labeled with tritium were used for studying the in vitro and in vivo biodegradation of the peptides. Tritium-labeled peptides with a specific radioactivity of 50-150 Ci/mmol were obtained by high temperature solid…
Experimental and theoretical demonstration of different effect of certain regulatory peptides (RPs) on blood coagulation is available. The problem of the role of RPs in hemostatic processes becomes particularly significant since, first, the peptides…
Peptide anxiolytic selank (Thr-Lys-Pro-Arg-Pro-Gly-Pro) applied intraperitoneally in doses of 0.01, 0.1, 1.0, and 10.0 mg/kg to mice reduces behavioral manifestations of dopaminergic system induced by apomorphine in the verticalization test. This eff…
The effects of Selank synthetic analog of Tuftsin, representing the heptapeptide forming Thr-Lys-Pro-Arg-Pro-Gly-Pro, on behavior and serotonin/noradrenalin concentrations in brain were investigated in adult rats exposed to hypoxia during 14-16 days…
TP-7 is a synthetic analogue of tuftsin. It has a structure of tuftsin, to which three natural L-amino-acids Pro-Gly-Pro are attached. This heptapeptide improves learning and memorization and causes antidepressant and anxiolytic effect. It is possibl…
Gateways to Clinical Trials are a guide to the most recent clinical trials in current literature and congresses. The data in the following tables have been retrieved from the Clinical Trials Knowledge Area of Prous Science Integrity, the drug discove…
INTRODUCTION: Melanocortins affect multiple physiological responses, including sexual behaviors. Bremelanotide is a synthetic peptide melanocortin analog of alpha-melanocyte-stimulating hormone that is an agonist at melanocortin receptors MC3R and MC…
The melanocortins (MCs) are a family of multifunctional peptidergic hormones. Several superpotent, prolonged acting, enzymatically resistant, MC analogs have been designed and synthesized to help clarify the nature and role of MCs and their receptors…
We report complete transection of major muscle and the systemic peptide treatment that induces healing of quadriceps muscle promptly and then maintains the healing with functional restoration. Initially, stable gastric pentadecapeptide BPC 157 (GEPPP…
Stable gastric pentadecapeptide BPC 157 (BPC 157, as an antiulcer agent in clinical trials for inflammatory bowel disease; PLD-116, PL 14736, Pliva, no toxicity reported) alone (without carrier) ameliorates healing of tendon and bone, respectively, a…
