One main source of cyanide (CN?) exposure for mammals is through the plant consumption; thus, the sensitive and selective cyanide detection in plant tissue is a significant and urgent work. Here, a simple sensor N′-(2,4-dihydroxybenzylidene)naphtha[2,1-b]furan-2-carbohydrazide (Q1-3) was designed and synthesized for selective and sensitive dual-channel detection of cyanide in aqueous medium (DMSO/H2O, 1:9, v/v). Acylhydrazone and phenolic hydroxyl groups on Q1-3 are the recognition sites, and naphthofuran group is the signal report group. The intramolecular charge transfer between the benzene group and naphthofuran group was impeded because of the electron-withdrawing groups (hydroxyl) on sensor Q1-3. Interestingly, the sensor Q1-3 exhibited an intramolecular charge transfer absorption band at 400?nm and emission band at 500?nm, respectively, directly realizing an “OFF–ON” response after the deprotonation process induced by cyanide anions in aqueous medium (DMSO/H2O, 1:9, v/v). Notably, this sensor was successfully applied to detect cyanide anions in food samples, which proves a very simple and selective platform for on-site monitoring of cyanide in agriculture samples. In addition, the test strips and silica gel plates based on Q1-3 were also fabricated, which could act as test kits and silica gel plates for convenient and efficient detection of cyanide anions.

The present invention relates to (E)-ethyl 2-(2-methyl-3-((2-(naphtho[2,1-b]furan-2-carbonyl)hydrazono)methyl)-1H-indol-1-yl)acetate as a novel tubulin polymerization inhibitor and a method for synthesizing the same. The compound of the present invention can inhibit mitosis and induce apoptosis and thus be used as an anticancer agent, by binding to tubulin to inhibit microtube polymerization. According to the synthesis method of the present invention, the reaction is simplified and the efficiency is 60%, or higher, leading to a very high yield, thereby providing an effective synthesis method.

Ethyl naphtho[2,1-b]furan-2-carboxylate has been prepared from 2-hydroxy-1- naphthaldehyde 1 and ethyl chloroacetate, which on further treatment with hydrazine hydrate gave naphtha[2,1-b]furan-2-carbohydrazide 3. The resulting compound 3 was treated with substituted aldehydes of 2-chloro-3-formylquinolines to give the Schiff base, which on treatment with chloro acetyl chloride gave the title compounds. The structure of the compounds has been confirmed by elemental analysis and spectral studies. The synthesized compounds were screened for their antibacterial and antifungal activities. ARKAT.
