A series of 7H-pyrrolo[2,3-d]pyrimidine derivatives were designed and synthesized as reversible BTK inhibitors, and evaluated their kinase selectivity, anti-proliferation against the B-cell lymphoma cell lines (Ramos, Jeko-1) and cell line BTK enhanced (Daudi) in vitro. Among them, compound 28a exhibited the most excellent potency (IC50 = 3.0 nM against BTK enzyme, 8.52 μM, 11.10 μM and 7.04 μM against Ramos, Jeko-1, Daudi cells, respectively), good kinase selectivity and inhibited BTK Y223 auto-phosphorylation and PLCγ2 Tyr1217 phosphorylation. Importantly, 28a showed efficacy anti-arthritic effect on collagen-induced arthritis (CIA) model in vivo. 28a 60 mg/kg dose level once a day group displayed markedly reduced joint damage and cellular infiltration without any bone and cartilage morphology change.

4-Fluoro and 4-hydroxy pyrrolidine-thioxotetrahydropyrimidinones: Organocatalysts for green asymmetric transformations in brine

, p. 5464 - 5473 (2015/06/16)
The synthesis of both trans- and cis-diastereomers of pyrrolidinine-thioxotetrahydropyrimidinone bearing either a fluorine or a hydroxyl group was accomplished. The new compounds were tested for their catalytic properties in a variety of asymmetric organic transformations and compared with the first generation catalyst. It was found that the new catalysts could efficiently catalyze the reactions in brine, without the use of organic solvent, and by employing an almost stoichiometric amount of reagents. Thus, the products were isolated by simple extractions, avoiding the use of chromatography in excellent yields, diastereoselectivities, and enantioselectivities.

An Efficient approach to the securinega alkaloids empowered by cooperative n-heterocyclic carbene/lewis acid catalysis
Elsohly, Adel M.,Wespe, Daniel A.,Poore, Tyler J.,Snyder, Scott A.
, p. 5789 - 5794 (2013/07/11)
Folding it all together: Most of the syntheses developed for the securinega alkaloid class require lengthy sequences to create their bridging butenolide domains. A novel approach uses N-heterocyclic carbenes (NHCs) and Lewis acids to forge the entire domain in a single step from appropriate precursors, showing that ynal-derived homoenolates can participate as nucleophiles in intramolecular settings (see scheme).

A novel method to access chiral nonnatural 2,4-disubstituted pyrrolidines from aldehydes and nitroolefins only with an α-substituent
Zheng, Bo,Wang, Hui,Han, Yong,Liu, Changlu,Peng, Yungui
, p. 4561 - 4563 (2013/06/04)
A series of α-substituted nitroolefins were employed in organocatalytic asymmetric Michael reactions with aldehydes. γ-Nitro carbonyl products were achieved in good yields (up to 86%) with good stereoselectivities (up to 96% ee and 24 : 1 dr). Reduction of the nitro group followed by intramolecular reductive amination successfully afforded various novel optically active 2,4-disubstituted pyrrolidine compounds.
Design, synthesis, and antileukemic activity of stereochemically defined constrained analogues of FTY720 (Gilenya)

FTY720 functions as an immunosuppressant due to its effect on sphingosine-1-phosphate receptors. At doses well above those needed for immunosuppression, FTY720 also has antineoplastic actions. Our published work suggests that at least some of FTY720's anticancer activity is independent of its effects on S1P receptors and due instead to its ability to induce nutrient transporter down-regulation. Compounds that trigger nutrient transporter loss but lack FTY720's S1P receptor-related, dose-limiting toxicity have the potential to be effective and selective antitumor agents. In this study, a series of enantiomerically pure and stereochemically diverse O-substituted benzyl ethers of pyrrolidines was generated and tested for the ability to kill human leukemia cells. The stereochemistry of the hydroxymethyl was found to be a key determinant of compound activity. Moreover, phosphorylation of this group was not required for antileukemic activity.
