Substituted acrylamides as factor Xa inhibitors: improving bioavailability by P1 modification
摘要:
To overcome the low bioavailability of our substituted acrylamide P1 benzamidine factor Xa inhibitors reported previously, neutral and less basic groups were used to replace the benzamidine. As a result, a series of P1 aminoisoquinoline substituted acrylamide Xa inhibitors was identified to be potent, selective, and orally bioavailable. Modification of P4 moiety of these compounds further improved their pharmacokinetic properties. (C) 2002 Elsevier Science Ltd. All rights reserved.
Discovery of Potent and Practical Antiangiogenic Agents Inspired by Cortistatin A
摘要:
The discovery that cortistatins A and J show noteworthy antiangiogenic activity prompted an investigation of the possibility that simpler and much more easily made compounds based on a steroid core might have useful bioactivity. These studies have led to the development of several potent, water-soluble compounds that may be suitable for local application to treat ocular wet macular degeneration, an important cause of blindness, as well as for treatment of various other angiogenesis-dependent diseases. One of these substances was tested in a mouse retinal angiogenesis model and found to inhibit angiogenesis at a locally administered dose of 500 pmol. Comparison of cell migration data for this and two other synthetic compounds with published data on cortistatin A indicate that they inhibit vascular endothelial growth factor-induced cell migration of human umbilical vein endothelial cells more strongly than cortistatin A.
