Article by Disease | Synthesis, Cytotoxicity and Antioxidant Activity of New Analogs of RC-121 Synthetic Derivatives of Somatostatin

Bentham Oncology Collection| Oncology | Cervical Cancer

 

 

 

Abstract:

Background: Based on the structure of RC-121 (D-Phe-c (Cys-Tyr-D-Trp-Lys-Val-Cys)-Thr-NH2, – synthetic derivatives of somatostatin), some analogs were synthesized and tested for in vitro cytotoxic and antioxidant activity.

Objectives: The new analogs were modifyed at position 5 with Dap (diaminopropanoic acid), Dab (diaminobutanoic acid) and Orn and at position 6 with the unnatural amino acids Tle (t-leucine).

Methods: The in vitro cytotoxic effects of the substances were investigated against a panel of human tumor cell lines HT-29 (Human Colorectal Cancer Cell Line), MDA-MB-23 (Human Breast Cancer Cell Line), Hep G-2 (Human Hepatocellular Carcinoma Cell Line) and HeLa (cervical cancer cell line). The antioxidant capacities were tested by ORAC (Oxygen Radical Antioxidant Capacity) and HORAC (Hydroxyl Radical Averting Capacity) methods.

Results: All substances expressed significantly higher antioxidant capacity by comparison with galic acid and Trolox. All substances showed considerable antioxidant capacity as well. Compound 2T (D-Phe-c(Cys-Tyr-DTrp- Dap-Tle-Cys)-Thr-NH2)had the highest antioxidant effect. The compound 4T (D-Phe-c(Cys-Tyr-D-Trp- Orn-Tle-Cys)-Thr-NH2) displayed antiproliferative effect on HeLa cells with IC50 30 μM. The peptide analog 3T (D-Phe-c(Cys-Tyr-D-Trp-Lys-Tle-Cys)-Thr-NH2) exerted the most pronounced inhibition on the cell vitality up to 53%, 56% and 65% resp. against MDA-MB-23, Hep G-2, HeLa in the higher tested concentration.

Conclusion: the somatostatin analogs showed moderate influence on the vitality of different tumor cells and could be used in changing their pathology.

Editor’s Choice Article | GUT-Brain Axis and Psychiatric Disorders

Journal Name: Current Psychiatry Reviews

Author(s): Alper Evrensel*, Uskudar University, Department of Psychiatry, Istanbul, Turkey Barış Önen Ünsalver, Uskudar University, Department of Psychiatry, Istanbul, Turkey Mehmet Emin Ceylan. Uskudar University, Department of Psychiatry, Istanbul, Turkey

 

Graphical Abstract:

Abstract:

Background: Studies on the effects of microorganisms living in the guts of human health and the etiopathogenesis of diseases, especially psychiatric disorders, have rapidly increased in recent years. According to the results of these studies, evidence has been found that there is direct and indirect (immune system) interaction between the microbiota bacteria and their metabolites and neurons.

Objective: The purpose of this review is to discuss the current research findings focusing on the relationship between the gut microbiota and psychiatric disorders. In this context, the effectiveness of microbiota-based treatments (probiotics and fecal microbiota transplantation) on the treatment of psychiatric disorders is also discussed.

Method: A review of the literature was conducted that includes the following words: gut-brain axis, microbiota, dysbiosis, psychiatry and mental disorders.

Results: There are few clinical studies examining the gut-brain relationship. In the light of the evidence from these clinical trials and animal experiments, it can be suggested that gut microbiota has a distinct and determinative role in brain function.

Conclusion: Gut microbiota creates a determining and life-long effect on the emergence of the immune system and the brain in the fetus starting with birth. Delivery mode, breastfeeding, diet, drugs (antibiotics, psychotropics) and aging may change the composition of gut microbiota. Disruption of microbiota composition (dysbiosis) may lead to the emergence of psychiatric disorders. Microbiotabased treatments have a therapeutic potential by repairing dysbiosis. There is a need for more randomized controlled studies in order for the effects of gut microbiota on psychiatric disorders to be completely understood.
