Sila-Analoga des Mebrophenhydramins

摘要

Sila-analoguesA2,B2 andC2 of the drug mebrophenhydramine from the class of benzhydryl ethers were synthesized for the first time by the steps shown in scheme 1, and they and their precursors I–III were characterized by their physical (Table 1) and chemical properties, and their structures confirmed by NMR, mass and infrared spectroscopy (Tables 3–5). The histaminolytic and anticholinergic effects ofA2 andC2 were investigated and compared with some structure-activity relationships of analogue carbon compou
