Introduction Acridine derivatives form an important class of heterocycles containing nitrogen due to their broad range of pharmaceutical properties. The reaction of the corresponding imines 34a—c with 9-chlorotacrine 35 in the presence of pentanol obtained compounds 36a—c Scheme 1. To date, many derivatives of acridine have been synthesized and tested for antitumour activity.

Additionally, it may be that a methoxy group into the pendant benzyl group imparted a higher activity than chlorine, methyl, and bromine substituents. IFM Furthermore, a weak interaction between chlorine and the backbone carbonyl group of amino acid is beneficial. It is a yellow powder, soluble in hot water. In this survey, we describe acridine and acridone derivatives reported since , methods of their synthesis and their potential clinical applications.

Thus monocyanoethylation of 4-methoxybenzylamine followed by treatment with 4-chlorobutyronitrile gave the dinitrile N- 2-cyanoethyl -N- 3-cyanopropyl methoxy-benzylamine. The carbon 9-position of acridine is activated for addition reactions. The target compounds 47a—p were synthesized by the reaction of propynyl acridinone derivatives 45 in the presence of CuI and the freshly prepared azide derivative These analogues were described as herbicide models, and their inhibition of photosynthesis was investigated against both photosystem I and II. Chrysaniline forms red-coloured salts, which dye silk and wool in a fine yellow; and the solutions of the salts are characterized by their fine yellowish-green fluorescence. Docking studies showed that the orientation of analogue 47b in the active site of AChE was the same as donepezil.
