Amylin as a Future Obesity Treatment
Babak Dehestani,Nicholas RS Stratford,Carel W. le Roux 대한비만학회 2021 The Korean journal of obesity Vol.30 No.4
Obesity is defined as abnormal or excessive fat accumulation that contributes to detrimental health impacts. One-third of the population suffers from obesity, and it is important to consider obesity as a chronic disease requiring chronic treatment. Amylin is co-secreted with insulin from β pancreatic cells upon nutrient delivery to the small intestine as a satiety signal, acts upon sub-cortical homeostatic and hedonic brain regions, slows gastric emptying, and suppresses post-prandial glucagon responses to meals. Therefore, new pharmacological amylin analogues can be used as potential anti-obesity medications in individuals who are overweight or obese. In this narrative review, we analyse the efficacy, potency, and safety of amylin analogues. The synthetic amylin analogue pramlintide is an approved treatment for diabetes mellitus which promotes better glycaemic control and small but significant weight loss. AM833 (cagrilintide), an investigational novel long-acting acylated amylin analogue, acts as a non-selective amylin receptor. This calcitonin G protein-coupled receptor agonist can serve as an attractive novel treatment for obesity, resulting in reduction of food intake and significant weight loss in a dose-dependent manner.
Indole-based derivatives effect on rats with polycystic ovary syndrome
Parichehreh Yaghmaei,Babak Dehestani,Samira Ghorbani,Farzaneh Abbasi,Azadeh Ebrahim‑Habibi 한국약제학회 2017 Journal of Pharmaceutical Investigation Vol.47 No.5
Polycystic ovary syndrome (PCOS) is a prevalent endocrine disorder in women of reproductive age, for which efficient therapies are needed. In this study, PCOS was induced in rats by intraperitoneal administration of testosterone propionate (0.2 mg/kg). Indole-based compounds 5-hydroxy indole-2-carboxylic acid, N-acetyl-tryptophan, Tryptamine, l-Tryptophan and Tryptophol were administered for 8 weeks in the PCOS model, after what histopathological assessment of ovaries was performed. The number of primary follicles, corpus luteum, growing follicles and graafian follicles increased and the number and diameter of ovarian cysts decreased in all treated rats in comparison with untreated group. In conclusion, l-Tryptophan and Tryptophol were most efficient as potential therapeutic molecules.
