Introduction of 129-03-3 :

Cyproheptadine is a potent and orally active 5-HT2A receptor antagonist, with antidepressant and antiserotonergic effects. Cyproheptadine has antiplatelet and thromboprotective activities. Cyproheptadine can be used for the research of thromboembolic disorders[1][2]. In Vitro:Cyproheptadine (0.01-100 nM; 1 minute) dose-dependently inhibits serotonin-enhanced ADP-induced mouse platelet aggregation in vitro[2].
Cyproheptadine (10 nM) has the ability to inhibit 15 μM serotonin-enhanced ADP-induced (1 μM) tyrosine phosphorylation in platelets in vitro[2].
Cyproheptadine inhibits human platelet PS exposure (Annexin V), P-selectin, and GPIIb-IIIa (PAC-1 binding) activation in vitro[2]. In Vivo:Note:
Please do not refer to only one article to determine the experimental conditions. It is recommended to determine the optimal experimental conditions (animal strain, age, dosage, frequency and cycle, detection time and indicators, etc.) through preliminary experiments before the formal experiment.

Cyproheptadine can be used in animal modeling to create diabetes models. In rats, Cyproheptadine undergoes demethylation and oxidation to form desmethylcyproheptadine (DMCPHepo), while cyproheptadine epoxide (CPHepo) is a minor metabolite. DMCPHepo accumulates in tissues and persists longer than predicted by its plasma concentration profile. DMCPHepo may be an active metabolite of Cyproheptadine and could be associated with islet cell damage. Additionally, the remaining dose of Cyproheptadine may be excreted via feces in the form of the parent compound or its metabolites[1].

Induction of Diabetes Disease[1].
Background
Cyproheptadine and its several metabolites, including desmethyl Cyproheptadine epoxide (DMCPH epoxide), desmethyl Cyproheptadine (DMCPH) and Cyproheptadine epoxide, inhibit insulin synthesis as well as glucose and stimulated insulin release[1].
Specific Modeling Methods
Rat: Wistar• male• weighing 150-225 g[3]
Administration: 0-90 mg/kg• p.o. or i.p.• daily for 14 days[3]
Mice: Swiss Webster• male• weighing 25-30 g[3]
Administration: 0-90 mg/kg• p.o.• daily for 14 days[3]
Rabbits: New Zealand white• male• weighing 1000-1500 g[3]
Administration: 0, 225mg/kg• p.o.• daily for 14 days[3]
Hamsters: Golden• male• weighing 100-150 g[3]
Administration: 0-90 mg/kg• p.o.• daily for 14 days[3]
Note
(1)Oral doses of Cyproheptadine were administered in aqueous solution or in an aqueous suspension containing 0.15 % methylcellulose. Intraperitoneally (ip)-treated rats received cyproheptadine in saline solution. Animals were sacrificed 24 h after the last dose[3].
(2)Animals were allowed food and water ad libitum throughout the study unless otherwise stated[3].
Modeling Indicators
Morphological change: Cyproheptadine caused a depression in weight gain and exhibited a markedly diminished glucose tolerance in animals[3].
Histological analysis: Cyproheptadine induced marked cytoplasmic vacuolization of islet cells in rat pancreas. Vacuoles varied in size and in the most severely affected cells occupied the major portion of the cytoplasm, displacing and slightly compressing the nucleus[3].
Organelle change: The majority of islet cells, presumably the β cell population, showed marked alteration of the rough endoplasmic reticulum and loss of secretory granules. Rough endoplasmic reticulum was vesiculated and the cisternae contained finely granular electron-dense material[3].
