Synthesis of Pyrrolidine 3,4-Diol Derivatives with Anticancer Activity on Pancreatic Tumor Cells
摘要:
Novel pyrrolidine 3,4-diol derivatives of the type (2R and 2S,3R,45){[(( 1R)-1-methoxycarbonyl and hydroxylmethyl)-1-arylmethyl)amino] ethyl}-pyrrolidine-3,4-diol have been prepared and evaluated as a-mannosidase inhibitors and assayed for their anticancer activity in vitro. They all exhibit specific but moderate activity as inhibitors towards a-mannosidase from Jack beans. Compounds 7 and 8b bearing hydroxymethyl and trifluoromethylbiphenyl groups show the best antiproliferative effect in two pancreatic cancer cell lines.
The "memory of chirality" stereodivergent synthesis of polyfluorobenzo[d]sultams has been developed. The interest of this protocol resides in the possibility of using the chirality of a starting sulfonamide single enantiomer to synthesize the target sultams in both absolute configurations, by using different base systems, under homogeneous conditions.
