  Exploration of Pharmacophore in Chrysosplenol C as Activator in Ventricular Myocyte Contraction

  摘要：

  Chrysosplenol C (4',5,6-trihydroxy-3,3',7-tri-methoxyflavone) isolated from Miliusa balansae has unique structural features as a reversible inotropic agent independent of beta-adrenergic signaling and with selective activation of cardiac myosin ATPase. Hence, a series of chrysosplenol analogues were synthesized and explored for identification of pharmacophore that is essential for the increasing contractility in rat ventricular myocytes. Analogue 7-chloro-2-(3-hydroxypheny1)-3-methoxy-4H-chromen-4-one showed highly potent contractility (54.8% at 10 mu M) through activating cardiac myosin ATPase (38.7% at 10 mu M). Our systematic structure activity relationship study revealed that flavonoid nucleus of chrososplenol C appears to be an essential basic skeleton and hydrophobic substituent at position 7 of chromenone such as methoxy or chloro enhances the activity. Additionally, our ATPase study suggested that these chrysosplenol analogues have selectivity toward cardiac myosin activation. Thus, the novel flavonone with 3-/7-hydrophobic substituent and 3'-hydrogen bonding donor function is a novel scaffold for discovery of a new positive inotropic agent.

  Velutin及其类似物的抗黑色素生成特性

  摘要：

  Velutin是天然植物中的一种黄酮，具有多种有益的活性，例如美白皮肤，以及抗炎，抗过敏，抗氧化和抗菌活性。但是，尚未研究velutin的结构与其抗黑素生成活性之间的关系。在这项研究中，我们通过化学合成获得了12种维他汀衍生物，这些化合物在黄酮骨架的C5，C7，C3'和C4'处被氢，羟基和甲氧基官能团取代，以进行维他汀结构类似物的SAR分析。SAR研究表明，黄酮骨架的C5，C7，C3'和C4'处的官能团取代会影响与黑色素合成有关的生物学活性。羟基和甲氧基在C5和C7位置的共存对于抑制酪氨酸酶活性至关重要。然而，在黄酮骨架的C3'和C4'处取代的1,2-二醇化合物诱导黑素瘤细胞凋亡。此外，在C3'和C4'处被甲氧基或氢取代对于抑制黑色素生成是必不可少的。因此，这项研究将有助于开发天然来源的功能材料，以调节黑色素的合成。

  Flavonoids are naturally occurring polyphenolic compounds and are among the most promising anticancer agents. A series of flavonols and their 3-methyl ether derivatives were synthesized and assessed for cytotoxicity. It was found that 3'-hydroxy-3,4'-dimethoxyflavone (flavonoid 7a) displayed strong cytotoxicity against human SK-MEL-1 melanoma cells and blocked tubulin polymerization, but had no significant cytotoxic effects against quiescent or proliferating human peripheral blood mononuclear cells. Our analyses showed that flavonoid 7a induces G2-M cell cycle arrest and apoptosis in melanoma cells which is associated with cytochrome c release and activation of both extrinsic and intrinsic apoptotic pathways of cell death.

The SAR study revealed that the substitution of functional groups at C5, C7, C3′, and C4′ of the flavone backbone affects biological activities related to melanin synthesis. The coexistence of hydroxyl and methoxy at the C5 and C7 position is essential for inhibiting tyrosinase activity. However, 1,2-diol compounds substituted
