A method is described for locating the 0-(2-hydroxypropyl) groups in 0-(2hydroxypropyl)-substituted guar. Per-0-methylation of the O-(Zhydroxypropyl)guar yielded guar that was partially 0-methylated and partially 0-(2methoxypropyl)ated. This polymer was hydrolyzed, to afford a mixture of partially
Samples of O-(2-hydroxypropyl)derivatives of cyclomaltoheptaose (beta-cyclodextrin) with increasing substitution were prepared by withdrawing aliquots at different times from a reaction mixture containing cyclomaltoheptaose and an excess of (S)-propylene oxide in 0.39 M aqueous sodium hydroxide. The
To clarify the involvement of the Rassf1a gene in lung carcinogenesis, we investigated the methylation status in the 5 0 upstream region of the RAS-association domain family 1, isoform A (Rassf1a) gene in rat lung adenocarcinomas induced by N-nitrosobis(2-hydroxypropyl)amine (BHP). Six-week-old male
