  o-Boronato- and o-Trifluoroborato–Phosphonium Salts Supported by l-α-Amino Acid Side Chain

  摘要：

  The synthesis of o-boronato- and o-trifluoroborato-phosphonium salts supported by the L-amino acid side chain is described. The synthesis of these new class of amino acid derivatives was achieved by stereoselective quaternization of o-(pinacolato)boronatophenylphosphine with) beta- or gamma-iodo amino acid derivatives which are prepared from L-serine or L-aspartic acid, respectively. The quaternization of the phosphine was performed using either iodo amino ester or carboxylic acid derivatives. In addition, free carboxylic acid and amine derivatives were obtained by saponification or HCl acidolysis of o-boronato-phosphonium amino esters, respectively. The usefulness of these compounds in peptide coupling was demonstrated by coupling an o-boronato-phosphonium amino ester with an aspartic acid moiety. When the o-boronato-phosphonium amino acid or dipeptide derivatives were mixed with fluoride, the corresponding o-trifluoroborated products were cleanly and rapidly obtained in high isolated yields. The hydrolysis of these compounds at room temperature using a phosphate buffer pH 7/CD3CN mixture has shown only traces of free fluoride F- after several days. Finally, a preliminary radiolabeling essay has proven the facile [F-18]-fluoride incorporation and high stability of the radiolabeled product in aqueous conditions. Indeed, this new class of boron-phosphonium amino acid derivatives shows promising properties for their applications in synthesis and labeling of peptides.

  The subject invention provides pharmaceutical compounds useful in the treatment of Type II diabetes. These compounds are advantageous because they are readily metabolized by the metabolic drug detoxification systems. Particularly, thiazolidinedione analogs that have been designed to include esters within the structure of the compounds are provided. This invention is also drawn to methods of treating disorders, such as diabetes, comprising the administration of therapeutically effective compositions comprising compounds that have been designed to be metabolized by serum or intracellular hydrolases and esterases. Pharmaceutical compositions of the ester-containing thiazolidinedione analogs are also taught.

  N-(4-methoxybenzyl)glycine/l-proline cyclohexapeptoid is the optimal catalyst (good yields and up to 75% ee) for the stereocontrolled construction of α-alkylated serine tert-butyl esters. Nonionic, chiral macrocyclic peptoids are efficient phase-transfer catalysts in the C-4 enantioselective alkylation of 2-[4-(trifluoromethyl)phenyl]-2-oxazoline-4-carboxylic acid esters.

  In a continued effort to improve upon the previously published 4-substituted methoxybenzoyl-aryl-thiazole (SMART) template, we explored chemodiverse “B” rings and “B” to “C” ring linkage. Further, to overcome the poor aqueous solubility of this series of agents, we introduced polar and ionizable hydrophilic groups to obtain water-soluble compounds. For instance, based on in vivo pharmacokinetic (PK)

  为了继续改进之前发表的 4-取代甲氧基苯甲酰基-芳基-噻唑 (SMART) 模板，我们探索了化学多样性的“B”环和“B”到“C”环的连接。此外，为了克服该系列试剂水溶性差的问题，我们引入了极性和可离子化的亲水基团以获得水溶性化合物。例如，基于体内药代动力学 (PK) 研究，设计并合成了一种口服生物可利用的苯基-氨基-噻唑 (PAT) 模板，其中在化合物1 的“A”和“B”环之间插入了一个氨基键. PAT 模板通过抑制微管蛋白聚合保持了对癌细胞系的纳摩尔 (nM) 范围效力，并且在体外不易受到 P-糖蛋白介导的多药耐药性的影响，与 SMART 模板相比，溶解度和生物利用度显着提高 ( 45a – c (PAT)与1（智能））。

  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。
