  The structure-antiaggregative activity relationship in a series of Arg-Gly-Asp analogues

  摘要：

  A series of analogues of Arg-Gly-Asp tripeptide, the common structural element of most of the integrin receptor ligands, possessing different conformational features for the interaction with platelet receptors, were synthesized by the methods of conventional peptide chemistry for use in the search for antithrombotic agents. The distance between the guanidine group of Arg and the beta-carboxyl group of Asp was shown to affect the antia-regative activity. A potent inhibitor of platelet aggregation, tripeptide Arg-beta Ala-Asp, with IC50 10.6 = 10.6 mu M (ADP, 1.5 gM) was revealed.

  Ferrocene (Fc) and its conjugates have attracted considerable attention in recent years due to their unique electrochemical behavior and significant biological activities such as antitumor, antimalarial, and antifungal. Arg-Gly-Asp (RGD)-containing peptides, because of their selective binding to integrins which are highly expressed in tumor-induced angiogenesis, play a key role in cancer targeted therapy. In this study. Fc-RGD and Fc-Am-RGD (Fc: ferrocenoyl; Am: 6-aminohexanoic acid) conjugates were synthesized, and the antitumor activities in vitro were investigated. The cell uptake of the conjugates by B16 murine melanoma cells was measured using HPLC-electrochemical method. The antitumor activities of the conjugates were also evaluated by 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide (MTT) and flow cytometric measurements. The experimental results revealed that Fc-RGD and Fc-Am-RGD exhibit more effective antitumor activities than their parent compounds RGD and Fc-COOH. Moreover, it is found that Fc-Am-RGD yields the lowest IC50 values of 5.2 +/- 1.4 mu M toward B16 cells. The HPLC-electrochemical studies confirmed that the insertion of flexible alkyl spacer Am between Fc and RGD significantly increases the cell uptake toward B16 cells and consequently improves the antitumor activity. Our results suggest that Fc-RGD and Fc-Am-RGD conjugates are potential candidates for cancer treatment. (c) 2012 Elsevier Inc. All rights reserved.
