Pure diastereomeric spirocyclic analogs of fluorocortivazol were conveniently prepared by a short and efficient synthetic sequence recently developed in our laboratory. The structures and conformations of several key products were confirmed by single crystal X-ray diffraction analysis. Conformational assignments were also supported by DFT calculations. Biological evaluation led to the identification of a highly potent hGR agonist with excellent anti-inflammatory effects in the subnanomolar range. All tested compounds from this series were also selective versus the progesterone receptor.
Cascade cyclization: An easy access to highly unsaturated polycyclic ring systems through a tandem stille/[4 + 2] reaction under mild conditions

Oxidative ring contraction of cyclic α-formyl ketones was facilitated by the action of H2O2under operationally simple and environmentally benign reaction conditions. The process was highly regioselective and enables stereospecific construction of contiguous quaternary all-carbon centers from stereodefined all-substituted all-cyclic ketones. The asymmetric syntheses of (+)-cuparene and (+)-tochuinyl acetate were also successively achieved by taking advantage of this novel protocol.
Synthesis and Oxidative Cleavage of Oxazinocarbazoles: Atropselective Access to Medium-Sized Rings

Polycyclic systems can be converted into medium-sized-ring-containing compounds through the controlled oxidative cleavage of internal double bonds. This approach is particularly accessible in systems that contain a suitably substituted indole ring. Here, a robust approach to the synthesis of the understudied oxazinocarbazole system is reported. After regioselective incorporation of a carbonyl functional group, m-chloroperoxybenzoic acid (MCPBA) is used to cleave the indole 2,3-double bond that this system contains. This results in a competition between two processes, oxidative cleavage of the double bond and a pinacol-type rearrangement, both of which occur with very high diastereoselectivity. The balance between the two processes is studied as a function of the substrate structure. Extensive use of X-ray crystallographic analysis of the products enables detailed mechanistic conclusions to be drawn.
A novel necroptosis inhibitor - Necrostatin-21 and its SAR study
Wu, Zhijie,Li, Ying,Cai, Yu,Yuan, Junying,Yuan, Chengye
supporting information, p. 4903 - 4906 (2013/09/02)
An initial structure-activity relationship study of the novel necroptosis inhibitor Nec-21 was described. Any changes of the tetracyclic scaffold were detrimental for the activity. Introduction of a substituent to 7 or 8 position (e.g., cyano or methoxy group, respectively), would increase the activity. The 7 and 8-position disubstituted compound 17b was 35-fold as potent as the lead, while EC50 reached 14 nM.
A back-to-front fragment-based drug design search strategy targeting the DFG-out pocket of protein tyrosine kinases
Iwata, Hidehisa,Oki, Hideyuki,Okada, Kengo,Takagi, Terufumi,Tawada, Michiko,Miyazaki, Yasushi,Imamura, Shinichi,Hori, Akira,Lawson, J. David,Hixon, Mark S.,Kimura, Hiroyuki,Miki, Hiroshi

We present a straightforward process for the discovery of novel back pocket-binding fragment molecules against protein tyrosine kinases. The approach begins by screening against the nonphosphorylated target kinase with subsequent counterscreening of hits against the phosphorylated enzyme. Back pocket-binding fragments are inactive against the phosphorylated kinase. Fragment molecules are of insufficient size to span both regions of the ATP binding pocket; thus, the outcome is binary (back pocket-binding or hinge-binding). Next, fragments with the appropriate binding profile are assayed in combination with a known hinge-binding fragment and subsequently with a known back pocket-binding fragment. Confirmation of back pocket-binding by Yonetani-Theorell plot analysis progresses candidate fragments to crystallization trials. The method is exemplified by a fragment screening campaign against vascular endothelial growth factor receptor 2, and a novel back pocket-binding fragment is presented.
