AI Article Synopsis

  • Preclinical safety tests of GB-115, a new dipeptide compound targeting cholecystokinin receptors, showed no fatalities in mice or rats after high doses.
  • Long-term oral administration in rabbits and rats did not cause permanent organ damage at doses of 0.1 and 10 mg/kg.
  • GB-115 exhibited no harmful effects such as allergies or mutations, and even reduced inflammation at a dose of 10 mg/kg.

Article Abstract

Preclinical safety investigations of newly synthesized dipeptide compound GB-115 (amide N-phenylhexanoyl-glycyl-L-tryptophan), an antagonist of cholecystokinin receptors, were performed. No animals were lost after GB-115 acute oral administration at a maximum dose of 6000 mg/kg in mice and at 3500 mg/kg in rats. GB-115 administered per os during 6 months in rabbits and rats (both males and females) at the doses of 0.1 and 10 mg/kg induced no irreversible pathological changes in organs and systems studied. The tested dipeptide exhibited no allergenic, immunotoxic and mutagenic activity, and did not affect generative function and the antenatal and postnatal development of progeny. GB-115 at a dose of 10 mg/kg produced suppression of the inflammatory reaction to concanavalin A.

Introduction: The developed domestic retrodipeptide analogue of cholecystokinin tetrapeptide (CCK) (N-(6-phenylhexanoyl)-glycyltryptophan amide, or compound GB-115) with antagonistic properties in relation to CCK1 receptors has anxiolytic activity previously shown in preclinical and clinical studies. The aim of the study was to evaluate the anxiolytic effect of GB-115 as a tablet form with subchronic oral administration in comparison with phenazepam in nonhuman primates.

Materials And Methods: The study was conducted on four male rhesus monkeys (Macaca mulatta) aged 5.

The study investigated the effect of GABA in various concentrations and D-GB-115 at a concentration of 10 M on the behavior of Paramecium caudatum. It was shown that GABA increases motor activity and changes the movement strategy of these protozoans, and the dose-effect relationship is domed, which can be explained by the presence of two types of GABA receptors in the outer membrane of paramecia: GABA-A and GABA-B. The active concentrations of GABA range from 10 to 10 M.

Aim: To evaluate anxiolytic action of GB-115, a low-affinity blocker of central cholecystokinin receptors, used in tablets in a dose of 1 mg for the treatment of patients with anxiety disorders in order to determine effective dose, safety, tolerability and efficacy in clinical settings.

Material And Methods: The study included 31 patients (22 women, 9 men) diagnosed with generalized anxiety disorder (GAD, F41.1 according to ICD-10), aged from 22 to 53 years.

The specific features of alcohol behavior were studied in MR and MNRA rats that exhibit an opposite reaction to emotional stress. We evaluated the effect of a dipeptide anxiolytic GB-115 (N-phenyl-hexanoyl-glycyl-L-tryptophan amide, neuropeptide cholecystokinin-4 analogue with antagonistic activity) on alcohol motivation in rats, which was formed over 12 months. High-emotionality MR rats were more sensitive to the anxiolytic effect of ethanol in the conflict situation test than low-emotionality MNRA rats.
