  Highly Stereocontrolled and Efficient Preparation of the Protected, Esterification-Ready Docetaxel (Taxotere) Side Chain

  摘要：

  A high-yield synthesis of the p-methoxybenzylidene-protected docetaxel (Taxotere) side chain, a useful derivative for efficient, epimerization-free esterification of the 7,10-bis[(trichloroethoxy)carbonyl] derivative of 10-desacetylbaccatin III for the preparation of docetaxel, has been effected; the C-4 and C-5 stereocenters of the 1,3-oxazolidine are generated with complete (greater-than-or-equal-to 99%) stereocontrol whereas that at C-2 is produced with 96% selectivity.

  Discovery of 1,4-Benzodiazepine-2,5-dione (BZD) Derivatives as Dual Nucleotide Binding Oligomerization Domain Containing 1/2 (NOD1/NOD2) Antagonists Sensitizing Paclitaxel (PTX) To Suppress Lewis Lung Carcinoma (LLC) Growth in Vivo

  摘要：

  Nucleotide-binding oligomerization domain-like receptors (NLRs) are intracellular sensors of pathogen-associated molecular patterns (PAMPs) and damage-associated molecular patterns (DAMPs). Previously, we reported nucleotide-binding oligomerization domain-containing protein 1 (NOD1) antagonists (II, 12) and a NOD2 antagonist (9) that sensitized docetaxel (DTX) or paclitaxel (PTX) treatment for breast or lung cancer. In this article, we describe for the first time a 1,4-benzodiazepine-2,5-dione (BZD) derivative (26bh) that acts as a dual NOD1/NOD2 antagonist and inhibits both nuclear factor kappa B (NF-kappa B) and mitogen-activated protein kinase (MAPK) inflammatory signaling, thereby sensitizing PTX to suppress Lewis lung carcinoma (LLC) growth. After investigation of the compound's cytotoxicity, a systematic structure-activity relationship (SAR) was completed and revealed several key factors that were necessary to maintain antagonistic ability. This study establishes the possibility for using adjuvant treatment to combat cancer by antagonizing both NOD1 and NOD2 signaling.

  A short, efficient approach to the p-methoxybenzylidene-protected paclitaxel (Taxol) side chain through benzaldehyde benzoylimine-chiral enolate condensation, followed by DDQ-mediated oxazolidine formation and hydrolysis is described; the C-7-triethylsilyl derivative of baccatin III undergoes esterification with this side chain in the presence of DCC and DMAP to provide after acid hydrolysis paclitaxel in excellent overall yield.

  6-bis-phosphate aldolases (FBAs) (e.g., from Mycobacterium tuberculosis), type I (zinc) phosphomannose isomerase (PMI) from Escherichia coli, and phosphoglucose isomerase (PGI) from yeast. In the case of FBAs, replacement of one phosphate by one malonate on a bis-phosphorylated inhibitor (1) led to a new compound (4) still showing a strong inhibition (Ki in the nM range) and class II versus class I selectivity

  在设计具有治疗意义的磷酸糖代谢酶和受体的抑制剂时，在许多情况下已报道丙二酸酯是磷酸酯基团的良好且水解稳定的替代物，因为这两种功能在生理pH下均为双阴离子，并且具有可比的大小。我们研究了最著名的II类（锌）果糖-1,6-双磷酸醛缩酶（FBA）（例如，来自结核分枝杆菌），I型（锌）磷酸甘露糖异构酶的磷酸盐抑制剂的一系列基于丙二酸的模拟物（PMI）来自大肠杆菌，以及磷酸葡萄糖异构酶（PGI）来自酵母。在FBA的情况下，在双磷酸化抑制剂上用一种丙二酸酯替代一种磷酸酯（1）导致了一种新化合物（4）。）仍显示出较强的抑制作用（K i在nM范围内），并且II类相对于I类选择性（高达8×10 4）。然而，其他磷酸盐的替代强烈影响结合效率和选择性。在PGI和PMI的情况下，5-脱氧-5- malonate- d -arabinonohydroxamic酸（8相比，其磷酸化的母体化合物5 -磷酸时），得到在结合亲和力很强的降低d

  Mechanism-based inhibitors of human cytomegalovirus (HCMV) protease have been designed based on the pyrrolidine-5,5-trans-lactam ring system. New routes to the beta -methyl-, desmethyl-, and alpha -methyl-pyrrolidine-5,5-trans-lactam templates have been developed from 2,4-diaminobutyric acid. ESI/MS studies have shown that these inhibitors can bind covalently and reversibly to the viral enzyme in a time-dependent manner by a mechanism which is consistent; with acylation of HCMV delta Ala protease at the active site nucleophile Ser 132. SAR in this series of pyrrolidine-5,5-trans-lactams has defined the relative stereochemisty of the methyl substituent adjacent to the lactam carbonyl, the functionality on the lactam nitrogen, and the mechanism of action of this novel series of serine protease inhibitors against the HCMV dAla protease. Activity decreases on moving from the alpha -methyl to the desmethyl to the beta -methyl series. This selectivity is the opposite of that observed for these templates against the elastase and thrombin enzymes. The activity against HCMV delta Ala protease is the greatest with inhibitors based on the Cbz-protected alpha -methyl-5,5-trans-lactam template which have low micromolar activity against the viral enzyme.
