本研究團隊在過去的研究中發現一個 β-nitrostyrene 類化合物,3,4-methylenedioxy-β-nitrostyrene(MNS)對於血小板凝集反應具有強效的抑制效果。此外, MNS 之苯甲醯基(benzoyl)取代衍生物 4-O-benzoyl-3- methoxyl-β-nitrostyrene(BMNS)對於由 thrombin 誘發血小板凝集的抑制能力約為 MNS 的 8 倍,且為非選擇性酪氨酸激酶抑制劑 genistein 與 tyrphostin A47 的 100 倍。另經由進一步研究指出 β-nitrostyrene 類化合物為一群具有抗血小板能力的新型酪氨酸激酶抑制劑,可以經由阻斷 GP IIb/IIIa 的活化而達到抑制血小板凝集的效果。綜上所述可以看出 β-nitrostyrene 類化和物具有開發為抗血小板藥物的潛力。因此為了進一步尋找更強效的抗血小板凝集的藥物,本研究團隊擬合成一系列新型的 β-nitrostyrene 衍生物,並進一步的探討其化學結構與活性的關係(structure-activity relationships, SAR)。在本研究中,共合成 47 個化合物,並測其抗血小板凝血活性。分析其活性結果,並歸納其 SAR 如下:
1. 所有化合物或市售之 β-nitrostyrene 類化合物皆具有抑制由thrombin 與 collagen 兩者所誘導之血小板凝集活性。
2. 對於 Series A 化合物而言,修飾其 B 環上取代基(R)之位置與基團時,可改變其活性;其中para-位置取代時,活性普遍較佳。
3. 對於 Series B 化合物而言:
a. 當 A 環部份改以其他芳香環取代(如CYT-RX17與CYT-RX18)時,其活性下降。
b. 當 A 環部份 para 位置改以 hydroxyl group 時,R3 取代基由 OCH3 變更為 OCH2CH3 時,其活性下降。
c. 當 A 環部份 para 位置改以 hydroxyl group 以其 isoteres(如 Cl 與 CH3)或其他基團(如 NO2 與 OCH3)時,其活性皆上升。其中以 NO2 與 Cl 取代為最佳,此數據顯示 A 環部份 para 位置取代拉電子基團或鹵素原子,可增加 β-nitrostyrene 類化合物之活性。
d. 當將 β-nitrostyrene 修飾為 β-methyl-β-nitrostyrenes(即R4由H取代改變為CH3時;如CYT-RX19與CYT-RX20,以及CYT-RX21與CYT-RX22),其活性下降。
In previous studies, 3,4-methylenedioxy-β-nitrostyrene (MNS) and 4-O-benzoyl-3-methoxyl-β-nitrostyrene (BMNS) exhibited inhibitory effector platelet aggregation via suppression of tyrosine kinases (Src and Syk). Furthermore, BMNS possessed 8 times greater potency than MNS, and 100 times greater potency than non-selective tyrosine kinases inhibitors (genistein and tyrphostin A47) in inhibiting thrombin-induced pletlet aggregation. Accordingly, β-nitrostyrenes derivatives were be as potential anti-platelet aggregation agent. In order to research and develop potent antiplatelet β-nitrostyrenes, we designed and synthesized a series of β-nitrostyrenes derivatives and evaluate their anti-platelet activities. On the basis of their bioactivities, the proposed structure-activity relationships(SARs) were as following.
1. All of the synthesized or commercial β-nitrostyrene derivatives inhibited platelet aggregation induced by thrombin or collagen.
2. For the compounds of Series A, the substitutes on the B ring influence the bioactivity. Of these, the derivatives with the para- substitutes are more potency.
3. For the compounds of Series B,
a. When the benzene ring (A ring) was replaced by thiophenyl or furanyl ring, (ex CYT-RX17 and CYT-RX18), the activity was decreased.
b. While the part of A ring in para-position is changed to hydroxyl group , the activity decreases.
c. While the para-hydroxyl group in the A ring was modified by its isoteres (e.g. Cl or CH3), or other groups (e.g. NO2 or OCH3), the activity all increases.
d. The bioactivities of β-methyl-β-nitrostyrenes (CYT-RX20 and CYT-RX22) were less then β-nitrostyrenes (CYT-RX19 and CYT-RX21).
