Synthesis of a new lactenediyne scaffold equipped with three handles
Banfi, Luca,Guanti, Giuseppe
, p. 7427 - 7429 (2002)
A new lactenediyne scaffold endowed with three attachment points for substituents (handles) was synthesized. This scaffold was designed in order to be used to prepare libraries of compounds possessing a tethered nucleophile, an activating substituent, and DNA-complexing substructures.

The scalable synthesis of the oxaquinolizidine marine natural product desmethylxestospongin B is based on the early application of Ireland–Claisen rearrangement, macrolactamization, and a late-stage installation of the oxaquinolizidine units by lactam reduction. The synthesis serves as the source of material to investigate calcium signaling and its effect on mitochondrial metabolism in various cell types, including cancer cells.

The first total synthesis of pericoannosin A (1) containing 15 steps in the longest linear sequence with an overall yield of 5.5% is reported. The hybrid peptide-polyketide was isolated from the endophytic fungus Periconia sp. F-31 and bears a unique tric
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

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 (11, 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 B (NF-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.

Compounds of Formulae (I') and (I) are described, which are useful as stimulators of sGC, particularly NO-independent, heme-dependent stimulators. These compounds are also useful for treating, preventing or managing various disorders that are herein disclosed.
Biomimetic synthesis, antibacterial activity and structure-activity properties of the pyroglutamate core of oxazolomycin
Angelov, Plamen,Chau, Yui Kwan Sonia,Fryer, Paul J.,Moloney, Mark G.,Thompson, Amber L.,Trippier, Paul C.
scheme or table, p. 3472 - 3485 (2012/06/01)
Biomimetic intramolecular aldol reactions on oxazolidine templates derived from serine may be used to generate densely functionalised pyroglutamates, which are simpler mimics of the right hand side of oxazolomycin. Some of the compounds from this sequence exhibit in vivo activity against S. aureus and E. coli, suggesting that pyroglutamate scaffolds may be useful templates for the development of novel antibacterials, and cheminformatic analysis has been used to provide some structure-activity data.
Toward a total synthesis of divergolide A; Synthesis of the amido hydro- Quinone core and the C10-C15 fragment
Zhao, Guanglian,Wu, Jinlong,Dai, Wei-Min
, p. 2845 - 2849 (2013/02/22)
A ring-closing metathesis (RCM) approach was envisioned for installing the E double bond at the C9 and C10 positions of divergolide A, isolated from a mangrove endophyte. Accordingly, the C10-C15 diene diol fragment and the amido hydroquinone core with the requisite functionalities and stereochemistry have been synthesized by using the norephedrine-based syn-selective glycolate aldol and the anti-selective aldol reactions, respectively. CuI-catalyzed amidation was employed to access the anilide intermediate, which was further transformed into the amido hydroquinone core. Copyright
[3,3]-sigmatropic rearrangement/5-exo-dig cyclization reactions of benzyl alkynyl ethers: Synthesis of substituted 2-indanones and indenes
Tudjarian, Armen A.,Minehan, Thomas G.
supporting information; experimental part, p. 3576 - 3581 (2011/06/25)
Substituted benzyl alkynyl ethers, prepared from the corresponding α-alkoxy ketones in a two-step sequence involving enol triflate formation and KOtBu-induced E2 elimination, undergo [3,3]-sigmatropic rearrangement/ intramolecular 5-exo-dig cyclization at 60 °C to form substituted 2-indanones in good overall yields. 1,3-cis-Disubstituted-2-indanones are formed preferentially when the benzylic substituent R1 is bulky. Substituted indenes may be prepared from 2-indanones in high yields by Horner-Wadsworth-Emmons reaction.
Practical preparation of benzyloxyacetic acids
Linn, Kathleen,Kuethe, Jeffrey T.,Peng, Zhihui,Yasuda, Nobuyoshi
, p. 3762 - 3765 (2008/09/21)
An efficient and practical method for the preparation of benzyloxyacetic acids is described. The procedure involves the reaction of readily available chloroacetic acid with benzyl alcohol in the presence of powdered KOH providing a safer alternative to the known literature procedures, which completely eliminates the use of pyrophoric bases such as sodium hydride and sodium metal.
