Aldehydes are relevant analytes in a wide range of samples, in particular, food and beverages but also body fluids. Hydrazines can undergo nucleophilic addition with aldehydes or ketones giving origin to hydrazones (a group of stable imines) that can be

Folic acid-conjugated magnetic ordered mesoporous carbon nanospheres (FA-MOMCNs) are developed as a targeting delivery vehicle of doxorubicin (DOX) in this work. Investigations on DOX loading mechanism show that the loading capacity of FA-MOMCNs is up to 577.12 mg g-1 by means of

A convenient and efficient synthesis of multi-substituted dihydropyrano[2,3-c]pyrazole derivatives is reported. The four-component reaction of 4-hydrazinobenzoic acid, β-keto esters, aromatic aldehydes, and malononitrile using 10 mol% CAN catalyst in water under ultrasound irradiation produced the target compounds in good-to-excellent yields.

Hydrazone chemistry has been firstly explored as capturing mode for interface supported toehold strand displacement cascade (TSDC). The method has been further established for analysis of 5-hydroxymethylfurfural (HMF) based on hydrazone chemistry-mediated TSDC. HMF containing aldehyde group can be covalently

4-Hydrazinobenzoic acid, an ingredient of mushroom Agaricus bisporus, is carcinogenic to rodents. To clarify the mechanism of carcinogenesis, we investigated DNA damage by 4-hydrazinobenzoic acid using (32)P-labeled DNA fragments obtained from the human p53 and p16 tumor suppressor genes. 4-Hydrazinobenzoic
