Novel Hypoxia-Inducible Factor 1alpha (HIF-1alpha) Inhibitors for Angiogenesis-Related Ocular Diseases: Discovery of a Novel Scaffold via Ring-Truncation Strategy

Ocular diseases featuring pathologic neovascularization are the leading cause of blindness, and anti-VEGF agents have been conventionally used to treat these diseases. Recently, regulating factors upstream of VEGF, such as HIF-1alpha, have emerged as a desirable therapeutic approach because the use of anti-VEGF agents is currently being reconsidered due to the VEGF action as a trophic factor. Here, we report a novel scaffold discovered through the complete structure-activity relationship of ring-truncated deguelin analogs in HIF-1alpha inhibition. Interestingly, analog 6i possessing a 2-fluorobenzene moiety instead of a dimethoxybenzene moiety exhibited excellent HIF-1alpha inhibitory activity, with an IC50 value of 100 nM. In particular, the further ring-truncated analog 34f, which showed enhanced HIF-1alpha inhibitory activity compared to analog 2 previously reported by us, inhibited in vitro angiogenesis and effectively suppressed hypoxia-mediated retinal neovascularization. Importantly, the heteroatom-substituted benzene ring as a key structural feature of analog 34f was identified as a novel scaffold for HIF-1alpha inhibitors that can be used in lieu of a chromene ring.

Synthesis of tetrahydro-1H,7H-benzo[ij]quinolizine-1,7-dione derivatives

Tetrahydro-1H,7H-benzo[ij]quinolizine-1,7-diones have been obtained by the cyclization of N-alkoxyphenyl-N-(2-carboxyethyl)-beta-alanines. Fission of the ester bond occurs on cyclization of N-(4-ethoxyphenyl)-N-(2-carboxyethyl)-beta-alanine, but the cyclization of the 3,4-dialkoxyphenyl derivative leads to the formation of 9-alkoxy-8-hydroxy-2,3,5,7-tetrahydro-1H,7H-benzo[ij]quinolizine-1,7-diones. The corresponding dioximes and diphenylhydrazones were obtained.

Cycloalkylation of C(sp3)-H Bond with Neighboring Carboxylic Acid as Traceless Activating Group

Selective functionalization of inert C(sp3)-H bond is one of cutting-edge challenges in chemical synthesis. A novel strategy for selective C(sp3)-H bond cycloalkylation is developed with neighboring carboxylic acid as a traceless activating group. Primary and secondary alkyl carboxylic acids undergo decarboxylation/alpha-C(sp3)-H cleavage/cycloalkylation to give the five-membered cyclization products, while tertiary acids undergo decarboxylation/beta-C(sp3)-H cleavage/cycloalkylation to generate the six-membered cyclization products.

Efficient hydrogenation of benzaldoximes and Schiff bases on ceramic high-porosity palladium catalysts

An efficient catalytic method for the synthesis of benzyl- and dibenzylamines by hydrogenating oximes and Schiffbases was developed on palladium supported high-porosity foamed ceramic block catalyst. The multiple regeneration ability of the foamed ceramic block catalyst can significantly decrease the Pd consumption as compared to the use of the conventional 10%Pd/C catalyst. Owing to a high hardness of the foamed ceramic catalyst, the reaction mixture can rapidly be removed from the reactor without using filtering devices. The structures produced by the reaction are fragments of biologically active and natural molecules. Antiproliferative properties of dibenzylamines revealed on the sea urchin embryo model suggest that these compounds can be considered as promising agents for the design of new anticancer drugs.

Discovery of novel guanidinophenylpyrazole human acrosin inhibitors by molecular hybridization

Human acrosin is a promising target for male contraceptives. A series of novel guanidinophenylpyrazole derivatives were rationally designed by molecular hybridization of the phenylpyrazole and guanidinobenzoate inhibitors. Most of the target compounds showed potent human acrosin inhibitory activities. In particular, compound F3 was a highly active human acrosin inhibitor (IC50 = 1.26 muM) with good selectivity over trypsin. Molecular docking studies revealed that compound F3 formed hydrophobic and hydrogen bonding interactions with the active site of human acrosin. Compound F3 represents a promising lead compound for the development of novel male contraceptives.

The titled compound showed, upon spectrophotometric titrations with Group II cations, a spectacular bathochromic shift (c.a. 50 nm) with Mg2+ but not with the other cations. This result is – understood in terms of internal charge-transfer species expressly favored by Et2N and ArCO substituents and best matching of ionic diameter and charge density of Mg2+. This finding may lead to new simple photoactive probes.
