1784-67-4 Usage
General Description
8,8'-Ethylenebistheophyline is a chemical compound that belongs to the class of theophylline derivatives. It is a dimer of theophylline, which is a methylxanthine drug used in the treatment of respiratory diseases such as asthma and chronic obstructive pulmonary disease (COPD). 8,8'-Ethylenebistheophyline has been studied for its bronchodilator and anti-inflammatory properties, which are important for managing respiratory conditions. It works by relaxing the smooth muscles in the airways and reducing inflammation, thereby improving breathing and reducing symptoms of respiratory diseases. 8,8'-Ethylenebistheophyline has shown potential as a therapeutic agent for respiratory conditions, and further research is being conducted to explore its efficacy and safety for medical use.
Check Digit Verification of cas no
The CAS Registry Mumber 1784-67-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,8 and 4 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1784-67:
(6*1)+(5*7)+(4*8)+(3*4)+(2*6)+(1*7)=104
104 % 10 = 4
So 1784-67-4 is a valid CAS Registry Number.

A Novel Synthesis of Theophylline Derivatives
Yoneda, Fumio,Koga, Ryosuke
, p. 813 - 816 (2007/10/02)
Treatment of 6-amino-5-arylazo-1,3-dimethyluracils with ethyl propiolate gave the corresponding Michael-type adducts, 5-arylazo-1,3-dimethyl-6-ethoxycarbonylvinylaminouracils, which on treatment with a mixture of hydrochloric acid and acetic acid caused the acid-catalyzed rearrangement accompanied with rearrangement to give rise to the corresponding 8-anilinomethyltheophylline derivatives.In the case that the arylazo group possesses an electron-releasing substituent such as methoxy, the reaction proceeded ina different way to afford 1,2-bis(theophyllin-8-yl)ethane.The presumable reaction mechanisms for the above purine syntheses were proposed.
