Azotides as Modular Peptide-Based Ligands for Asymmetric Lewis Acid Catalysis
Jacobsen, Christian Borch,Nielsen, Daniel Steen,Meldal, Morten,Diness, Frederik
, p. 6940 - 6945 (2019/06/10)
Synthesis of azotides and evaluation of these as ligands for enantioselective Lewis acid catalysis is reported. The ligands were readily prepared from the chiral pool of amino acids and perform well in the cobalt(II)-catalyzed formation of asymmetric hete
Polythiazole linkers as functional rigid connectors: A new RGD cyclopeptide with enhanced integrin selectivity

Polythiazole amino acids clasp linear peptides to generate cyclic derivatives, however, the resulting species are not merely stapled peptides but bear a complex heterocyclic moiety displaying its intrinsic set of interactions. As a proof of concept, a bisthiazole moiety has been grafted onto an RGD sequence to deliver a new cilengitide analogue with improved integrin selectivity and remarkable in vivo antiangiogenic activity.
Core refinement toward permeable β-secretase (BACE-1) inhibitors with low hERG activity
Ginman, Tobias,Viklund, Jenny,Malmstr?m, Jonas,Blid, Jan,Emond, Rikard,Forsblom, Rickard,Johansson, Anh,Kers, Annika,Lake, Fredrik,Sehgelmeble, Fernando,Sterky, Karin J.,Bergh, Margareta,Lindgren, Anders,Johansson, Patrik,Jeppsson, Fredrik,F?lting, Johanna,Gravenfors, Ylva,Rahm, Fredrik

By use of iterative design aided by predictive models for target affinity, brain permeability, and hERG activity, novel and diverse compounds based on cyclic amidine and guanidine cores were synthesized with the goal of finding BACE-1 inhibitors as a treatment for Alzheimer's disease. Since synthesis feasibility had low priority in the design of the cores, an extensive synthesis effort was needed to make the relevant compounds. Syntheses of these compounds are reported, together with physicochemical properties and structure-activity relationships based on in vitro data. Four crystal structures of diverse amidines binding in the active site are deposited and discussed. Inhibitors of BACE-1 with 3 μM to 32 nM potencies in cells are shown, together with data on in vivo brain exposure levels for four compounds. The results presented show the importance of the core structure for the profile of the final compounds.

Novel phenolic thiazoles compounds were prepared which demonstrated potent antioxidant activity and potent in vivo neuroprotection in mitochondrial toxin models and also possess good oral bioavailability.
Synthesis of primary thioamides from nitriles and hydrogen sulfide catalyzed by anion-exchange resin
Liboska, Radek,Zyka, Daniel,Bobek, Miroslav
, p. 1649 - 1651 (2007/10/03)
A new method has been developed for converting nitriles into primary thioamides. Treatment of various nitriles (Table 1, entries 1-12) with gaseous hydrogen sulfide in a mixture of methanol-water or ethanol-water and in the presence of anion-exchange resin (Dowex 1X8, SH- form) at room temperature and ambient pressure gave the corresponding thioamides in 25-96% yield.

A new asymmetric synthesis of (S)-dolaphenine and its heteroaromatic congeners utilizing (+)-2-hydroxy-3-pinanone and (-)-3-hydroxy-2-caranone as chiral auxiliaries
Irako, Naoko,Hamada, Yasumasa,Shioiri, Takayuki
, p. 12731 - 12744 (2007/10/02)
(+)-2-hydroxy-3-pinanone ((+)-HyPN,(+)-2a) and (-)-3-hydroxy-2-caranone ((-)-2b) were respectively converted to the corresponding Schiff bases 18a and 18b with 1-(2-thiazolyl)methylamine (17). Alkylation followed by removal of the chiral auxiliaries (+)-2a and (-)-2b afforded (S)-dolaphenine (10) as an optically pure form. The method was applied to the asymmetric synthesis of the dolaphenine analogs 27a-d.
