The synthesis and evaluation of new benzophenone derivatives as tubulin polymerization inhibitors

Inspired by the potent inhibition activity of phenstatin and millepachine against cancer cell growth, a series of new benzophenone derivatives were synthesized and evaluated as tubulin polymerization inhibitors. Among them, compound 10a exhibited 0.029-0.062 μM of IC50 for five human cancer cell lines, which is much better than that of the two leading compounds. Flow cytometric analysis showed that 10a induces G2/M phase arrest and apoptosis in A549 cells. Cellular studies revealed that the induction of apoptosis by 10a was associated with the collapse of the mitochondrial membrane potential (MMP). Overall, the current study demonstrates that the benzophenone derivatives are promising anticancer agents by targeting tubulin.

1,4-Benzodioxane Lignans: An Efficient, Asymmetric Synthesis of Flavonolignans and Study of Neolignan Cytotoxicity and Antiviral Profiles

1,4-Benzodioxane lignans are a class of bioactive compounds that have received much attention through the years. Herein research pertaining to both 1,4-benzodioxane flavonolignans and 1,4-benzodioxane neolignans is presented. A novel synthesis of both tra

Synthesis and Photoswitching Properties of Bioinspired Dissymmetric I-Pyrone, an Analogue of Cyclocurcumin

Cyclocurcumin (CC), a turmeric curcuminoid with potential therapeutic properties, is also a natural photoswitch that may undergo E/Z photoisomerization under UV light. To be further exploited in relevant biological applications, photoactivation under near-infrared (NIR) irradiation is required. Such requirement can be met through opportune chemical modifications, by favoring two-photon absorption (TPA) probability. Herein, a general and efficient synthesis of a biomimetic 2,6-disubstituted-δ-pyrone analogue of CC is described, motivated by the fact that molecular modeling previews an order of magnitude increase of its NIR TPA compared to CC. Three retrosynthetic pathways have been identified (i) via an aryl-oxazole intermediate or via aryl-diynone through (ii) a bottom-up or (iii) a top-down approach. While avoiding the passage through unstable synthons or low-yield intermediate reactions, only the latest approach could conveniently afford the 2,6-disubstituted-I-pyrone analogue of CC, in ten steps and with an overall yield of 18%. The photophysical properties of our biomimetic analogue have also been characterized showing an improved photoisomerization yield over the parent natural compound. The potentially improved nonlinear optical properties, as well as enhanced stability, may be correlated to the enforcement of the planarity of the pyrone moiety leading to a quadrupolar D-π-A-π-D system.

Indazole compounds and pharmaceutical compositions for inhibiting protein kinases, and methods for their use

Indazole compounds that modulate and/or inhibit the activity of certain protein kinases are described. These compounds and pharmaceutical compositions containing them are capable of mediating tyrosine kinase signal transduction and thereby modulate and/or inhibit unwanted cell proliferation. The invention is also directed to the therapeutic or prophylactic use of pharmaceutical compositions containing such compounds, and to methods of treating cancer and other disease states associated with unwanted angiogenesis and/or cellular proliferation, such as diabetic retinopathy, neovascular glaucoma, rheumatoid arthritis, and psoriasis, by administering effective amounts of such compounds.

Synthesis of compounds of interest in proton transfer spectroscopy

A new series of compounds has been prepared for use in proton transfer spectroscopy. The complexes 6a-6d have been converted into the fully characterised perchlorates 7a-7d and the corresponding anhydro bases 8a-8d.
