OBJECTIVE: The clinical use of growth hormone-releasing hormone (GHRH) is limited by its short half-life. Polyethylene glycol-conjugated GHRH (PEG-GHRH) was developed to provide increased stability compared with the currently available GHRH(1-29). Th…
In situ hybridization on paraffin sections of the rat brain showed that synthetic peptides Vilon, Epithalon, and Cortagen modulated the expression of IL-2 gene in vivo in cells of some hypothalamic structures depending on the terms and routes of admi…
Epithalon (regulatory tetrapeptide) labeled with dansil (fluorescent stain) easily penetrates into all tissues and organs of pregnant rabbit females and through the placenta into fetal organs. Incorporation of labeled epithalon in placental tissues i…
PROBLEM: Gerontology observations show that ageing of organism is accompanied by the decrease of the chromatin activity and slowing down of the protein synthesis. Natural regulatory oligopeptides and their synthetic analogues take part in the activat…
Female senescence accelerated mice SAMP-1. (prone) and SAMR-1 (resistant) were exposed 5 times a week monthly to melatonin (with drinking water 20mg/ml during the night hours) or to s.c. injections of epitalon (Ala-Glu-Asp-Gly) at a single dose 1mkg/…
The purpose of this research was to study age-related changes in functioning of pineal and pancreatic glands of non-human primates, rhesus monkeys, and to elucidate the possibility of their corrections with the help of epitalon, a synthetic analogue…
Gateways to Clinical Trials is 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 discover…

OBJECTIVE: To investigate the effects of TH9507, a novel growth hormone releasing factor, on abdominal fat accumulation, metabolic and safety parameters in HIV-infected patients with central fat accumulation. DESIGN AND METHODS: Randomized, double-bl…
We studied the seasonal effects of peptide preparation Selank on orientation and exploratory activity in 36 arctic ground squirrels Citellus undulatus in the open-field and hole-board tests. Selank most significantly increased behavioral activity of…
The effects of the new heptapeptide anxiolytic drug selank (300 mg/kg, i.v.) on the arterial pressure (AP), cerebral blood flow, heart rhythm, respiration, and the AP depression induced by acetylcholine injections was recorded in narcotized male cats…
The present concept of relative instability of regulatory peptides (RPs) in organisms must be amended. The recently characterized family of glyprolines and some other prolyl-glycyl-proline (PGP)-containing oligopeptides show the stability quite compa…
The influence of a new heptapeptide Selank on microcirculation in anesthetized white rats was investigated. Selank (Thr-Lys-Pro-Arg-Pro-Gly-Pro) is a new synthetic anxiolytic which exerts obvious antiulcerogenic action and promotes healing of experim…

OBJECTIVES: To evaluate the safety and pharmacodynamic effect of co-administration of subtherapeutic doses of PT-141, a cyclic heptapeptide melanocortin analogue, and sildenafil to patients with erectile dysfunction. METHODS: Nineteen patients with e…
We evaluated the role of human gastric pentadecapeptide BPC 157 in corneal epithelial defects healing in rats. 48 rats, in 4 groups (N=12). Total debridement of corneal epithelium preformed unilaterally and lesions stained and photographed. Animals m…
Serotonin syndrome commonly follows irreversible monoamine oxidase (MAO)-inhibition and subsequent serotonin (5-HT) substrate (in rats with fore paw treading, hind limbs abduction, wet dog shake, hypothermia followed by hyperthermia). A stable gastri…
The stable gastric pentadecapeptide BPC 157 (GEPPPGKPADDAGLV; mol. wt. 1419), which is at present in phase II clinical trials for the treatment of inflammatory bowel disease, has been shown to counteract healing impairment by systemic corticosteroids…
