Significant improvements in the realm of a recently disclosed, novel synthetic concept towards the Iboga alkaloid family are presented. The key step for the construction of the bicyclic aliphatic core consists of an intramolecular nitrone-olefin 1,3-dipolar cycloaddition reaction of a 1:1 mixture 15/16 yielding the two diastereoisomeric tricyclic isoxazolidine derivatives 17 and 18. The required nitrones were prepared from the readily available (S)-hydroxylactone 6 in twelve steps with an oyerall yield of 15% (average: 83.5% per step). The relative configuration of the minor isomer was deduced unambiguously by single-crystal X-ray analysis of the derived tricyclic carbamate 21. As four out of five asymmetric centers in the pair 17/18 have opposite configuration, destruction of the one possessing the same absolute configuration transforms the original set of diastereoisomers into a pair of enantiomers. We verified this contention by oxidizing the two alcohols 20 and 22 to yield the two antipodal forms of ketone 23. The absence of significant amounts of by-product and the high reproducibility of the crucial cycloaddition reaction represent marked improvements over our earlier attempts. In addition, the new route, which starts from L-glutamate, should provide access to both naturally occurring antipodal series of the targeted alkaloid class.

Indirubins have been identified as potent ATP-competitive protein kinase inhibitors. Structural modifications in the 5-and 3?-position have been extensively investigated, but the impact of substituents in 5?-position is not equally well-studied. Here, we report the synthesis of new indirubin 3?-and 5?-derivatives in the search of water-soluble indirubins by introducing basic centers. Antiproliferative activity of all compounds in tumor cells was evaluated along with kinase inhibition of selected compounds. The results show the 3?-position to tolerate large substituents without compromising activity, whereas bulk and rigid substituents in 5?-position appear unfavorable. Screening molecular targets of water-soluble 3?-oxime ethers revealed 6ha as preferential inhibitor of insulin-like growth factor 1 receptor (IGF-1R) in a panel of 22 protein kinases and in cells. Consistently, 6ha inhibited tumor cell growth in the NCI 60 cell line panel and induced apoptosis. The results indicate that the 5?-position provides limited space for chemical modifications and identify 6ha as a potent water-soluble indirubin-based IGF-1R inhibitor.

Transition metal ion-assembled three-helix bundle proteins provide templates to investigate the thermodynamic and dynamic structural consequences of the deletion of a single backbone hydrogen bond from an I±-helical architecture. This deletion does not perturb the steady-state secondary structure of the protein as measured by circular dichroism spectroscopy but does decrease the overall folding free energy by ca. 0.7 kcal/mol. We have used intraprotein electron transfer as a measure of the structure-sensitive dynamics of our system. The deletion of a single hydrogen bond in one of the helices of a three-helix bundle does not significantly change the measured electron-transfer rate. This is in agreement with “Greenpath” electron-transfer pathway calculations, which assume a constant and invariant structure for the architecture. Given the exponential dependence of electron-transfer rate on distance and that fluctuations in the intervening secondary structure will cause variations in electron donor-acceptor distances, the measured electron-transfer rate associated with hydrogen bond deletion allows us to calculate a differential dynamic structural fluctuation associated with hydrogen bond deletion of less than 0.6 AI¿ over the millisecond time scale of the experiment.
