  Synthesis and antiviral activities of novel acylhydrazone derivatives targeting HIV-1 capsid protein

  摘要：

  HIV-1 capsid protein (CA) plays important roles in the viral replication cycle. A number of acylhydrazone derivatives that act as inhibitors of HIV-1 CA assembly, were designed and synthesized. The synthesized compounds were tested for their antiviral activities and cytotoxicities using CEM cells. Some derivatives also were assayed for their ability to inhibit HIV-1 CA assembly in vitro. Among them, compounds 14f and 14i display the most promising potency with EC50 values of 0.21 and 0.17 mu M, respectively. (C) 2009 Elsevier Ltd. All rights reserved.

  Constrained Analogues of Procaine as Novel Small Molecule Inhibitors of DNA Methyltransferase-1

  摘要：

  Constrained analogues of procaine were synthesized, and their inhibiting activity against DNMT1 was tested. Among them, the most potent compound, derivative 3b, was also able to induce a recognizable demethylation of chromosomal satellite repeats in HL60 human myeloid leukemia cells and thus represents a lead compound for the development of a novel class of non-nucleoside DNMT1 inhibitors.

  The present invention provides an improved process for preparing an oxazoline compound of the formula: (I) wherein R1 and R2 are independently hydrogen, sulfide, sulfoxide, sulfonyl, optionally substituted lower alkyl, optionally substituted aralkyl, optionally substituted aryl or optionally substituted polycyclic arylyl; or R1 and R2 combined together with the carbon atoms to which they are attached form an optionally substituted fused 6-member aromatic ring provided that R1 and R2 are attached to carbon atoms adjacent to each other; and R3 is hydrogen, sulfide, sulfoxide, sulfonyl, optionally substituted lower alkyl, optionally substituted aralkyl, optionally substituted aryl or optionally substituted polycyclic arylyl; or an enantiomer therof; or an enantiomeric mixture therof; comprising the step of contacting an acylamino alcohol compound to a suitable amount of fluoroalkanesulfonyl fluoride compound and organic basic reagent. By using a fluoroalkanesulfonyl fluoride compound with an organic basic reagent, the present invention efficiently converts acylamino alcohol compounds into highly chemoselective oxazoline compounds with a remarkable variety of substrates, mild conditions and relatively short reaction time.

  本发明提供了一种改进的制备氧杂环丙烯酮化合物的方法，其化学式为：(I)，其中R1和R2分别为氢、硫化物、亚氧化物、磺酰基、可选择取代的较低烷基、可选择取代的芳基烷基、可选择取代的芳基或可选择取代的多环芳基；或者R1和R2与它们附着的碳原子结合在一起形成可选择取代的融合6-环芳香环，前提是R1和R2附着在彼此相邻的碳原子上；而R3为氢、硫化物、亚氧化物、磺酰基、可选择取代的较低烷基、可选择取代的芳基烷基、可选择取代的芳基或可选择取代的多环芳基；或其对映体；或其对映体混合物；包括将酰胺醇化合物与适量的氟代烷磺酰氟化合物和有机碱性试剂接触的步骤。通过使用氟代烷磺酰氟化合物和有机碱性试剂，本发明能够高效地将酰胺醇化合物转化为高度化学选择性的氧杂环丙烯酮化合物，适用于多种底物，反应条件温和，反应时间相对较短。

  During the syntheses and studies of natural iron chelators (mycobactins), we serendipitously discovered that a simple, small molecule, oxazoline-containing intermediate 3 displayed surprising anti-tuberculosis activity (MIC of 7.7 μM, average). Herein we report elaboration of SAR around this hit as well as the syntheses and evaluation of a hundred oxazoline- and oxazole-containing compounds derived from

  在天然铁螯合剂（分枝杆菌素）的合成和研究过程中，我们偶然发现一种简单的小分子含恶唑啉中间体3表现出令人惊讶的抗结核活性（平均MIC为7.7 μM）。在此，我们报告了围绕这一打击的 SAR 详细阐述，以及从有效的三步过程衍生的一百种含恶唑啉和恶唑化合物的合成和评估：1）与丝氨酸或苏氨酸形成 β-羟基酰胺； 2)环化得到恶唑啉； 3)脱水得到相应的恶唑。通过这种方法制备的许多化合物显示出具有令人印象深刻的抗结核分枝杆菌活性、极低的毒性和因此高的治疗指数，以及对更顽固的非复制形式的结核分枝杆菌的活性。它们结构的独特性和简单性应该使它们能够进一步优化以满足 ADME（吸收、分布、代谢、排泄）要求。八种最有效的体外化合物的合成得到了扩大，并在小鼠体内感染模型中测试了这些化合物，以评估其功效，然后再进行更精细的化合物设计和优化。
