As of my last update in October 2023, there is no specific information available regarding a chemical substance with the name "INDEX NAME NOT YET ASSIGNED" and CAS number 2712455-05-3. This may indicate that the substance is either newly synthesized, not widely studied, or not yet characterized in the scientific literature. Typically, a CAS number is assigned to a chemical compound to facilitate its identification and provide a unique reference. Characteristics of a chemical substance generally include its molecular formula, structure, physical properties (such as melting point, boiling point, and solubility), and chemical reactivity. For newly identified compounds, details may emerge over time as research progresses and the substance is studied further. If you are looking for specific information about this compound, I recommend checking scientific databases, journals, or regulatory agency resources for the most current data.

Cyproheptadine-d
3
is intended for use as an internal standard for the quantification of cyproheptadine  by GC- or LC-MS. Cyproheptadine is an antihistamine with antiserotonergic and anticholinergic activities.
1
It binds to histamine H
1
, muscarinic, and serotonin 5-HT
2
receptors (K
i
s = 0.38, 1.26, and 0.83 nM, respectively, in radioligand binding assays).
2
Cyproheptadine reduces histamine-induced spasms in isolated guinea pig ileum (IC
75
= 0.0014 μg/ml).
3
It protects against intravenous histamine diphosphate-induced death with a 50% protective dose (PD
50
) value of 0.08 mg/kg and delays induction of aerosolized histamine diphosphate-induced coughing (ED
100sec
= 0.29 mg/kg) in guinea pigs. Cyproheptadine also inhibits the lysine methyltransferase SET7/9 (IC
50
= 1 μM), decreasing the expression of estrogen receptor α (ERα) in MCF-7 cells.
4
Formulations containing cyproheptadine have been used in the treatment of allergic reactions including rhinitis, conjunctivitis, and urticaria.
