- Structure-Based Optimization of 3-Phenyl-N-(2-(3-phenylureido)ethyl)thiophene-2-sulfonamide Derivatives as Selective Mcl-1 Inhibitors
-
Selective Mcl-1 inhibitors may overcome the drug resistance caused by current anti-apoptotic Bcl-2 protein inhibitors in tumors with Mcl-1 overexpression. Based on previously discovered compounds with a 3-phenylthiophene-2-sulfonamide core moiety, in this work, we have obtained new compounds with improved binding affinity and/or selectivity under the guidance of structure-based design. The most potent compounds achieved sub-micromolar binding affinities to Mcl-1 (Ki～ 0.4 μM) and good cytotoxicity (IC5015N-heteronuclear single-quantum coherence NMR spectra suggested that these compounds bound to the BH3-binding groove on Mcl-1. Several cellular assays revealed that FWJ-D4 as well as its precursor FWJ-D5 effectively induced caspase-dependent apoptosis, and their target engagement at Mcl-1 was confirmed by co-immunoprecipitation experiments. Treatment with FWJ-D5 at 50 mg/kg every 2 days on an RS4;11 xenograft mouse model for 22 days led to 75% reduction in tumor volume without body weight loss.

- Method for preparing azoxystrobin on basis of Suzuki reaction
-
The invention relates to a method for preparing azoxystrobin on basis of a Suzuki reaction. The method comprises the following steps: dissolving a mixture composed of methyl (E)-2-[2-(6-chloropyrimidinyl-4-yloxo)phenyl]-3-methoxy acrylate, cesium carbonate and 2-cyanophenol according to a molar ratio of 1:2:2 in a solvent, stirring at 85DEG C under the protection of N2 for 7h, and separating and purifying the obtained mixture to prepare azoxystrobin. The novel green synthesis method provided by the invention has the advantages of low cost, high yield, simple process, and suitableness for mass production.

- Stereoselective synthesis of (±)-rocaglaol analogues
-
(Chemical equation presented) An intramolecular hydroxy epoxide opening was used to access the cyclopenta[d]benzofuran ring system of the natural product rocaglaol (2). Our route allowed the stereocontrolled preparation of the rocaglaol derivative (±)-(1S*,3S*,3aR*,8bS*)-3b. The synthesis of the (±)-(3R*)-epimer of 3b was also achieved. Our strategy is well-suited for the production of analogues with variation of the western ring.
