- Design, synthesis and biological evaluation of deuterated nintedanib for improving pharmacokinetic properties
-
Nintedanib is a novel triple angiokinase inhibitor that inhibits three growth factors simultaneously. Deuterated derivatives of nintedanib at certain metabolically active sites were prepared and evaluated in vitro and in vivo. In particular, deuterated compound SKLB-C2202 had significantly improved pharmacokinetic properties compared with nintedanib. These efforts lay the foundation for further investigating the druggability of SKLB-C2202. Deuterated derivatives of nintedanib at certain metabolically active sites were prepared and evaluated in vitro and in vivo. Deuterated compound SKLB-C2202 had significantly improved pharmacokinetic properties compared with nintedanib. Further research is underway.

- Design, synthesis, and evaluation of indolinones as triple angiokinase inhibitors and the discovery of a highly specific 6-methoxycarbonyl-substituted indolinone (BIBF 1120)
-
Inhibition of tumor angiogenesis through blockade of the vascular endothelial growth factor (VEGF) signaling pathway is a newtreatment modality in oncology. Preclinical findings suggest that blockade of additional pro-angiogenic kinases, such as fibroblast and platelet-derived growth factor receptors (FGFR and PDGFR), may improve the efficacy of pharmacological cancer treatment. Indolinones substituted in position 6 were identified as selective inhibitors of VEGF-, PDGF-, and FGF-receptor kinases. In particular, 6-methoxycarbonyl-substituted indolinones showed a highly favorable selectivity profile. Optimization identified potent inhibitors of VEGF-related endothelial cell proliferation with additional efficacy on pericyctes and smooth muscle cells. In contrast, no direct inhibition of tumor cell proliferation was observed. Compounds 2 (BIBF 1000) and 3 (BIBF 1120) are orally available and display encouraging efficacy in in vivo tumor models while being well tolerated. The triple angiokinase inhibitor 3 is currently in phase III clinical trials for the treatment of nonsmall cell lung cancer.

- Synthesis and photophysical characterization of a new, highly hydrophilic caging group
-
o-Nitrobenzyl-protected bioactive compounds are useful tools in biophysics, allowing controlled photorelease of biologically active compounds with high temporal and spatial precision. Thus, it is possible to study biological processes, such as neurotransmitter-receptor interaction, and many other processes, in much more detail than before. In this respect, these caged compounds have become established as extremely useful tools. In some cases, however, their biological properties (the caged compound should not interact with the biological system), their photochemical properties (quantum yield and kinetics of the photorelease), and their physical properties (high hydrophilicity) are not satisfactory. In order to address the last problem, we examined means to increase the hydrophilicity of caged compounds based on the o-nitrobenzyl moiety. Here, we report the synthesis and the photochemical and biological characterization of a new caged Daspartate derivative with vastly improved hydrophilicity, compared to derivatives reported previously, and satisfactory photophysical properties. Caged compounds with this improved o-nitrobenzyl group may thus represent a valuable new tool for different kinds of biophysical investigations. Wiley-VCH Verlag GmbH, 69451 Weinheim, Germany, 2002.
