Methylation of 7-amino-l,2,3-triazolo[4,5-d]pyrimidine (8-azaadenine) (140) with dimethyl sulfate afforded the N-3 and N-9 methylated isomers 141 and 142, respectively, which upon further methylation with methyl iodide or benzenesulfonic acid methyl ester gave 3,7- and l,9-dimethyl-8-azaadeninium salts 144 and 145, respectively. Thermal decomposition of the dimethyl derivatives led to a transmethylation to give 6-methylamino-9-methyl-8-azapurine (143), whose methylation afforded 1- and 7-methyl-6-methylamino-9-methyl-8-azapurinium salts 146 and 147 (80ZOR2204) (Scheme 28).

A number of substituted benzenesulfonic acid esters and p-chlorophenoxy-isobutyric acid esters produced hypolipidemic activity.35 Among a series of p-alkoxybenzoic acids, enhanced hypotriglyceridemic and hypocholesterol-emic activity was observed with oximino- (14) and chloro- (15) substituents.98 Hypocholesterolemia was observed after the administration of 16 to rats.97 Tetronic 701, a polymeric surfactant, also lowered serum cholesterol the tetrabenzoate of Tetronic 701 is of particular interest, since it produced comparatively less growth depression.98 Two linoleamide derivatives, (-)N-fa-phenyl-B-(p-tolyl)ethylllinoleamide (PTLA) and N-(a-methyl-benzoyl)linoleamide, suppressed serum and liver cholesterol levels in rats and inhibited cholesterol absorption b interfering with the hydrolysis of cholesteryl esters in the intestine.99 101...

The sulfonate esters decompose in aqueous solutions to the corresponding sulfonic acids and alcohols. The rate of decomposition of the sulfonate esters of primary alcohols depends on the stability of the sulfonate ion formed upon hydrolysis. For example, in sodium phosphate at pH 7.9 and 25°, ethyl 2-benzothiazolesulfonate (Ha) and methyl 4-nitro-benzenesulfonate (I) have half-lives of about 12 and 60 min, respectively. Isopropyl 2-benzothiazolesulfonate (Ilb) proved to be very reactive to...
