Abstract

In our investigations to synthesize inhibitors of smooth muscle cell (SMC) proliferation, compound 6a displayed submicromolar activity in in vitro antiproliferative assays and reduced intimal thickening using a rat balloon angioplasty model via i.v. administration. In order to identify analogs that could be administered orally, the chemical instability of the C-4',6' acetal of compound 6a was addressed. Several novel variants with increased acid stability and comparable in vitro activity were prepared.
