Abstract: | APLRV, SLRR, RGDS, and RGDF were synthesized by use of the solution method via the corresponding protective intermediates. After fragment condensation and deprotection, APLRVRGDS, APLRVRGDF, SLRRRGDS, and SLRRRGDF were obtained. The effect of these RGD containing peptides on rat aortic strips pretreated with noradrenaline (NE) were observed. The relaxing extents of contracted strips for them at three doses (10(-5) mol/L, 10(-6) mol/L and 10(-7) mol/L) indicated that, in a few cases, this kind of combination of these fragments may enhance the desirable activity. |
