  Fluorocyclopentenyl-cytosine with Broad Spectrum and Potent Antitumor Activity

  摘要：

  On the basis of the potent biological activity of cyclopentenyl-pyrimidines, fluorocyclopentenyl-pyrimidines were designed and synthesized from D-ribose. Among these, the cytosine derivative 5a showed highly potent antigrowth effects in a broad range of tumor cell lines and very potent antitumor activity in a nude mouse tumor xenograft model implanted with A549 human lung cancer cells. However, its 2'-deoxycytidine derivative 5b did not show any antigrowth effects, indicating that 2'-hydroxyl group is essential for the biological activity.

  设计，合成和生物学评估氟内啡肽A作为新型的基于机制的S-腺苷同型半胱氨酸水解酶抑制剂。

  摘要：

  Fluoroneplanocin A（12）被设计为一种新型的基于机制的S-腺苷同型半胱氨酸水解酶（SAH）抑制剂，并通过亲电乙烯基氟化反应（-78℃下的n-BuLi，N-氟苯磺酰亚胺）有效合成。氟尿素链球菌素A的SAH抑制活性比亲本Neplanocin A强2倍。这项工作中发现的不可逆抑制的新机制可能为设计通过SAH抑制作用的另一类抗病毒药提供新的选择。

• Regio- and stereoselective synthesis of 2′-β-substituted-fluoroneplanocin A analogues as potential anticancer agents

  日期：——

  A series of 2′-β-substituted-6′-fluoro-cyclopentenyl-pyrimidines and -purines 8 and 9 were successfully synthesized from D-ribose in a regio- and stereoselective manner. The functionalization at the C2-position of 6′-fluoro-cyclopentenyl nucleosides was achieved via regioselective protection of a hydroxyl group at the C3-position and stereoselective formation of C2-triflate followed by direct SN2 reaction

• X-ray Crystal Structure and Binding Mode Analysis of Human <i>S</i>-Adenosylhomocysteine Hydrolase Complexed with Novel Mechanism-Based Inhibitors, Haloneplanocin A Analogues

  The X-ray crystal structure of human S-adenosylhomocysteine (AdoHcy) hydrolase was first determined as a tetrameric form bound with the novel mechanism-based inhibitor fluoroneplanocin A (4b). The crystallized enzyme complex showed the closed conformation and turned out to be the intermediate of mechanism-based inhibition. It confirmed that the cofactor depletion by 3'-oxidation of fluoroneplanocin A contributes to the enzyme inhibition along with the irreversible covalent modification of AdoHcy hydrolase. In addition, a series of haloneplanocin A analogues (4b-e and 5b-e) were designed and synthesized to characterize the binding role and reactivity of the halogen substituents and the 4'-CH2OH group. The biological evaluation and molecular modeling studies identified the key pharmacophores and structural requirements for the inhibitor binding of AdoHcy hydrolase. The inhibitory activity was decreased as the size of the halogen atom increased and/or if the 4'-CH2OH group was absent. These results could be utilized to design new therapeutic agents operating via AdoHcy hydrolase inhibition.
