Highly regioselective and sustainable solar click reaction: A new post-synthetic modified triazole organic polymer as a recyclable photocatalyst for regioselective azide-alkyne cycloaddition reaction

The synthesis of pharmaceutically active 1,2,3-triazoles has been continuously scrutinized in the search for unique and effective catalysts to make the process efficient, green, and sustainable. Here, we are presenting a new visible light active Ni(ii) cyclam-integrated triazole-linked organic polymer (Ni-TLOP) photocatalyst for the synthesis of 1,2,3-triazole compounds with excellent efficiency and regioselectivity. The reaction was studied for a series of substrates and the absolute regioselectivity of a representative triazole product has also been confirmed by X-ray crystallography. The proficiency and chemical orthogonality of the Ni-TLOP are remarkable and it shows enhanced efficiency and regioselectivity. The use of a recyclable photocatalyst and non-hazardous reagents makes the catalytic system sustainable and environmentally friendly. This photocatalyzed click reaction technique has been successfully applied to the expedient synthesis of one of the most sold anti-epileptic drugs rufinamide.

Using the same hydroxamic acid derivative and HDAC8 inhibitor (by machine translation)

Disclosed are: a compound which is capable of inhibiting the function of HDAC8; and an HDAC8 inhibitor. Specifically disclosed is a hydroxamic acid derivative which is characterized by being composed of a compound represented by general formula (1) (wherein X represents an aromatic substituent or an optionally substituted 3-8 membered ring, and n represents an integer of 0-20), or a pharmaceutically acceptable salt, hydrate, solvate or prodrug thereof.

Rapid discovery of highly potent and selective inhibitors of histone deacetylase 8 using click chemistry to generate candidate libraries

To find HDAC8-selective inhibitors, we designed a library of HDAC inhibitor candidates, each containing a zinc-binding group that coordinates with the active-site zinc ion, linked via a triazole moiety to a capping structure that interacts with residues on the rim of the active site. These compounds were synthesized by using click chemistry. Screening identified HDAC8-selective inhibitors including C149 (IC50 = 0.070 μM), which was more potent than PCI-34058 (6) (IC50 = 0.31 μM), a known HDAC8 inhibitor. Molecular modeling suggested that the phenylthiomethyl group of C149 binds to a unique hydrophobic pocket of HDAC8, and the orientation of the phenylthiomethyl and hydroxamate moieties (fixed by the triazole moiety) is important for the potency and selectivity. The inhibitors caused selective acetylation of cohesin in cells and exerted growth-inhibitory effects on T-cell lymphoma and neuroblastoma cells (GI50 = 3-80 μM). These findings suggest that HDAC8-selective inhibitors have potential as anticancer agents.
