Khalifa, Mohamed E.
, (2021)
Nine new purine-based compounds were designed and have been synthesized through series reactions of the starting compound 8-amino-substituted purine (2) with various reagents. Full characterizations of the synthesized compounds were performed to elucidate

The present invention relates to adenosine A3 receptor antagonists and their use for the prevention and treatment of atherosclerosis by administering to a mammal, in need thereof, a therapeutically effective amount of an adenosine A3 receptor antagonist, or a pharmaceutically acceptable salt thereof, alone or in combination with other anti-atherosclerotic agents.

Heating of 8-aminotheophylline with methyl (Z)-2-benzoylamino-3- (dimethylamino)propenoate in acetic acid afforded in a one-pot synthesis a new pyrimido[2,1-f]theophylline derivative. Methylation of this by using CH 3I/NaH furnished in good yield the double methylated derivative. Furthermore, glycosidation of the former with 1-α-bromo-2,3,4,6-tetra-O- acetyl-d-glucose gave the β-glucoside derivative. Reaction of 8-aminotheophylline with [bis(methylthio)methylene]malonitrile, ethyl[bis(methylthio)methylene]cyanoacetate, 1,3-diphenylprop-2-en-1-one, 2-cyano-1,3-diphenylprop-2-en-1-one, 1-(4-nitrophenyl)-3-(dimethylamino)prop-2- ennitrile, 1-phenyl-3-(dimethylamino)prop-2-en-1-one, 2-substituted 3-aryl or heteroarylprop-2-ennitrile and ethyl(arylmethylene)cyanoacetate in N,N-dimethylformamide in the presence of anhydrous potassium carbonate afforded also the corresponding new derivatives of pyrimido-[2,1-f]theophylline. However, 8-aminotheophylline reacted in similar manner with 3-chloropentan-2,4-dione and 2-bromo-1-phenylethanone to give the corresponding imidazo[2,1-f]theophyllines. Furthermore, azo-coupling of one of these with 4-methylphenyldiazonium chloride was performed. The antimicrobial activity of the products has been evaluated. The structures of all new compounds obtained were established by their spectral analyses.

We recently described the synthesis of 1-benzyl-3-propyl-1H,8H-imidazo[2,1-f]purine-2,4-diones, new potent and selective A3 adenosine receptor antagonists containing a xanthine core. The present work can be considered an extension of our SAR st
