Small Molecule Inhibitors of the Neuropilin-1 Vascular Endothelial Growth Factor A (VEGF-A) Interaction
摘要:
We report the molecular design and synthesis of EG00229,2, the first small molecule ligand for the VEGF-A receptor neuropilin 1 (NRP1) and the structural characterization of NRP1-ligand complexes by NMR spectroscopy and X-ray crystallography. Mutagenesis Studies localized VEGF-A binding in the NRP1 b1 domain and it peptide Fragment of VEGF-A was shown to bind at the same site by NMR, providing the basis for small molecule design. Compound 2 demonstrated inhibition of VEGF-A binding to NRP1 and attenuated VEGFR2 phosphorylation in endothelial cells. Inhibition of migration of endothelial cells was also observed. The viability of A549 lung carcinoma cells wits reduced by 2, and it increased the potency of the cytotoxic agents paclitaxel and 5-fluorouracil when given in combination. These studies provide the basis for design of specific small molecule inhibitors of ligand binding to NRP1.
Synthesis of Substituted Benzenes via Bi(OTf)3-Mediated Intramolecular Carbonyl Allylation of α-Prenyl or α-Geranyl β-Arylketosulfones
摘要:
Intramolecular carbonyl allylation of alpha-prenyl or alpha-geranyl beta-arylketosulfones 5 in the presence of molecule sieves (MS) affords substituted benzenes 6-7 in moderate to good yields. The facile transformation proceeds by a synthetic sequence starting with the alpha-prenylation or alpha-geranylation of 1 and the Bi(OTf)(3)-mediated annulation of 5 followed by a sequential desulfonative aromatization or then an intramolecular FriedelCrafts alkylation. A plausible mechanism has been studied and proposed.

2-Aryl-indenylphosphine ligands: design, synthesis and application in Pd-catalyzed Suzuki–Miyaura coupling reactions
A focused library of phosphine ligands was constructed for structural optimization. The catalyst can be used to perform the Suzuki–Miyaura cross-coupling reaction of aryl and heteroaryl chlorides.
An easily available Pd(OAc)2/(2-(anthracen-9-yl)-1H-inden-3-yl) dicyclohexylphosphine/toluene/iPrOH/water catalyticsystem was developed, which shows high catalytic activity in the Suzuki–Miyaura cross-coupling reactions of a diverse array of aryl and heteroaryl chlorides with Pd loadings down to 0.01 mol%.

lndazole-3-carboxamide compounds for treating various diseases and pathologies are disclosed. More particularly, the present disclosure concerns the use of an indazole-3- carboxamide compound or analogs thereof, in the treatment of disorders characterized by the activation of Wnt pathway signaling (e.g., cancer, abnormal cellular proliferation, angiogenesis and osteoarthritis), the modulation of cellular events mediated by Wnt pathway signaling, as well as genetic diseases and neurological conditions/disorders/diseases due to mutations or dysregulation of the Wnt pathway and/or of one or more of Wnt signaling components. Also provided are methods for treating Wnt-related disease states.
